Abstract
To elucidate factors underlying the increased risk of developing Alzheimers disease (AD) in older individuals, the prefrontal cortices of younger (58-79 years) and of older (over 80 years) AD patients were examined by silver impregnation, TUNEL assay and immunohistochemistry for hyperphosphorylated tau, LDH and two growth factors (BDNF, NGF). Quantitative data were compared with those of age-matched controls. TUNEL-positive cells were mainly located in superficial cortical layers of younger and in deeper layers of older AD patients. Their density was more than 5 times higher in older AD than in younger AD (p < or = 0.05), but apoptotic cell morphology was rarely seen. Significantly more neuronal somas were contacted by degenerating fibers both in younger and older AD cortices. Density of tau-immunoreactive cells, which were virtually absent in controls, was twice as high in older AD patients as in younger AD individuals (p < or = 0.05). In younger AD, TUNEL positive cells generally lacked tau immunoreaction, whereas in older AD, most cells were double-labeled for hyperphosphorylated tau and TUNEL (p < or = 0.05). Numerical density of BDNF-immunoreactive cells was significantly reduced by 20 percent in older AD patients, compared to both control individuals and younger AD patients, whereas density of NGF-positive cells was the same in all patient groups examined. The distinct differences between younger and older AD patients suggest a faster progression of AD in older patients.

Abstract
Influential factors of electrical thresholds for electrically evoked potentials elicited by intraorbital stimulation of the optic nerve, including stimulation positions of the optic nerve, stimulating electrodes, frequency and duration of electrical pulses and pathological status of the optic nerve, were evaluated in 48 pigmented rabbit eyes. Intravenous injection of sodium iodate was used to induce transneuronal degeneration of the retinal ganglion layer subsequent to photoreceptor death. Two equations were derived to predict electrical thresholds needed to elicit cortical responses.

Abstract
A study has been made of the origin and course of the centrifugal fibres in the visual pathway of the pigeon using the Nauta method. Lesions in the mid-brain involving the isthmo-optic nucleus result in fibre degeneration which can be traced through the isthmo-optic tract to the chiasma and thence into the contralateral optic nerve and retina. In the retin a severe degeneration is found throughout the optic nerve layer, and occasional degenerating fibres can be traced through the ganglion cell layer to the inner aspect of the bipolar cell layer. Here they terminate in endings similar to those described by Cajal (1889) and Dogiel (1895) in relation to amacrine cells. The projection to the retina is completely crossed. Counts of the number of cells in the isthmo-optic nucleus indicate that the number of centrifugal fibres is approximately 10000; they form 1 % of the total number of fibres in the optic nerve. The isthmo-optic nucleus receives afferents from the tectum, and in this projection there would appear to be a well-defined organization.

Abstract
Most silver methods for the demonstration of senile plaques (SP) in Alzheimer's disease (AD) give variable staining of SP and often stain a variety of other structures (including normal axons, neurofibrillary tangles (NFT), blood vessel reticulin, nucleoli of neurons, and nuclei of glia). A newly developed silver method for paraffin sections is described in this report that reliably stains densely arrayed fine processes in SP. Other structures, including NFT, are not darkly stained. The high-contrast staining of SP greatly facilitates the mapping and morphometry of SP using videomicroscopic image analysis systems and provides a new method for other research studies on SP and for diagnostic histopathology.

Abstract
The product of the permeability x vascular surface rate area (PA) of the blood-brain barrier to [14C]sucrose has been measured in rats raised on synthetic diets in which the saturated/unsaturated fat constitution was controlled at high or low levels. Gas-liquid chromatography demonstrated marked differences in brain fatty acid constitution between the dietary groups. No statistically significant differences was found between the permeability measurements in rats maintained on any of the synthetic diets, nor was there any difference from rats raised on a standard laboratory pellet food. The opportunity was taken to look at 3 other properties of brain that might be affected by lipid constitution. There was no change in the form of the membranous intracellular inclusions that can be induced by intracerebral injections of suramin, and Fink-Heimer staining of degenerating axons, which is inhibited by fat extraction, worked equally well on each diet group. The sleep time after an anaesthetic injection of alcohol was not significantly changed.

Abstract
The superficial layers of the viper optic tectum, which receive fibers from he retina, were studied using both light and electron microscopes. The optic fibers layer, or stratum opticum, is composed of 200 to 250 tight fascicles containing thin fibers, nearly all of which are myelinated. The main optic terminal layers, the stratum griseum et fibrosum superficiale, the greatest part of the cellular population is composed of small vertically oriented neurons and horizontal nerve cells, many of which are probably local circuit neurons. The neuropil of the stratum griseum et fibrosum superficiale is made up of small nerve elements, including three types of profiles containing synaptic vesicles; 1) boutons with pleiomorphic synaptic vesicles (P), representing over 47% of the total population of profiles containing synaptic vesicles and comprising three subgroups (P1, P2, and P3); 2) boutons with spheroidal synaptic vesicles (S), forming more than 29% of the total populations of profiles containing synaptic vesicles and comprising two categories, S1 and S2 (S2, the more numerous, represents the optic boutons, which make up 22% of the total populations of profiles containing synaptic vesicles); and 3) dendrites with pleiomorphic vesicles, accounting for approximately 23% of the total populations of profiles containing synaptic vesicles. A study of synaptic patterns revealed a large number of serial synapses and a lesser number of triplets or triadic synapses. The presynaptic components are boutons containing spheroidal (S1, S2) or pleiomorphic (P1, P2, P3) synaptic vesicles. The intermediate profile was always a dendrite with synaptic vesicles which frequently belonged to the small neurons of the stratum griseum et fibrosum superficiale. Comparison of the present results with other recent data shows that the synaptic circuitry in the optic tectum of Vipera aspis closely resembles the pattern observed in the optic tectum of other vertebrates, ranging form fish to mammals. However, quantitative differences exist, especially with regard to the proportion of dendrites containing synaptic vesicles. Their number seems to be higher in sauropsidians than in mammals, particularly in primates.

Abstract
This work represents an attempt to elucidate structural features of electrophysiologically characterized, individual cat dorsal spinocerebellar tract (DSCT) neurons by using intracellular application of horseradish peroxidase (HRP). Intracellular recordings and HRP injections were made in DSCT neurons of the Clarke's column in cat lumbar (L3) spinal cord. The units were identified by antidromic invasion following electrical stimulation of the ipsilateral dorsolateral funiculus at C1. In addition, sensory inputs to the DSCT neurons were determined by natural (adequate) stimuli applied to the hind limb with intact innervation. The morphological analysis is based on data obtained from 19 well-stained electrophysiologically identified neurons located in Clarke's column. Thirteen of these units received excitatory sensory inputs from muscle receptors, two were activated by cutaneous afferents only, and four had a convergent (muscle + cutaneous) input. The DSCT--muscle cells were equivalent to the large Clarke cells (class C of Leowy, '70). Their dendrites were oriented primarily in the rostro--caudal direction (up to 2500 micron) and appeared generally smooth except for some branchlets. In four of these cells, the axon was traced into the lateral funiculus. In light microscopic analysis there was no evidence that axon collaterals arose from these axons during the initial trajectory through the spinal grey matter. The four DSCT--convergent neurons were similar in shape to the DSCT--muscle units although they appeared to have somewhat smaller cell bodies. Of the two DSCT--cutaneous neurons one was found to be of the B type, with the dendritic tree having fewer branches and oriented mainly in the medio--lateral direction. The other cell, however, turned out to be similar in appearance to the C type Clarke neurons.

Abstract
Factors influencing the consistency and specificity of the staining of neuronal degeneration products were studied in brain sections by varying systematically the composition of solutions used in the steps which are common to the degeneration methods. The formation of nuclei of metallic silver was determined either by physical development of 110Ag, after dissolving reducible silver by acetic acid. In degenerating axons metallic silver nucleic are formed by their own reducing groups in the first (acid) and in the second (alkaline) impregnating bath. The first impregnation turned out to be sufficient to produce complete staining of degenerating axons. The reducing capacity of normal axons and myelin can be suppressed by oxidation or by lowering the pH of the impregnating solution. Degenerating axon terminals are not able to reduce silver ions in either of the impregnating baths. Rather, the metallic silver nuclei initiating their staining are formed in the Nauta reducer by interaction of its reducing agent (formol) with silver ions which had been trapped in the tissue during the impregnation. Thus the nuclei are enlarged to microscopic visibility by a nonstandardized physical developer coming about from the Nauta reducer and the silver ions transferred with the sections. In this reaction catalytic sites in degenerating terminals as well as ammonium ions and the alkali reserve of the tissue play an important role. On the basis of the present results it was possible to stabilize the conditions for staining degenerating axons and degenerating axons terminals in two separate staining procedures detailed in following papers.

Abstract
The abdominal nerve cord of the leech Macrobdella decora was studied under the light and electron microscopes. The ganglionic cortex consists of six hemicone-shaped packets of neuronal perikarya and apical processes regularly assembled in bilaterally symmetric rows. The orderly projection of the apical processes into the hilum of the packets is also followed by an orderly distribution of their branches across the neuropile. This part of the ganglion is made of two symmetrical halves or hemineuropiles enclosing two types of nerve tissue: coarse and fine neuropiles. The coarse neuropile has seven longitudinal and four commissural tracts of fibers and a distinctively segregated synaptic zone. Nerve processes in this neuropile mostly proceed from the neurons in the ganglia and some are the branches of giant afferent axons. The fine neuropile includes several longitudinal tracts of fibers and a non-segregated synaptic zone. Most nerve processes in this neuropile are small afferent axons and some come from neurons in the ganglia. Bundles of axons in the connectives result by the orderly projection of the neuropile longitudinal tracts and together form fiber pathways connecting the synaptic zones of successive ganglia. Pathways of through-ganglia giant axons, linking the coarse neuropile synaptic zones, and of small axons, linking the fine neuropile synaptic zones, are described.

Abstract
The spastic mutant, found in the Mexican axolotl, shows swimming coordination and equilibrium deficiencies. Histological analyses of wild-type and spastic mutant cerebella previously characterized in physiological studies revealed changes in Purkinje cell location in the mutant auricle or vestibulo-cerebellum. Purkinje cells are "translocated" ventrally correlated with a similar translocation of vestibular single units described previuosly (Ide, '77). Where wild-type Purkinje cells are distributed from the surface to a depth of 250 micrometers, mutant Purkinje cells are "crowded" between 250 and 350 micrometers. Although mutant granule cells are present, boundaries between granule cell and Purkinje cell zones are less precise in mutants. Cerebellar nucleus cells are translocated medially, failing to organize into the discrete cell group appearing in wild-type. Cerebellar white matter tracts and fibers show changes, both in orientation with respect to the underlying tegmentum, and in fascicular organization. Obvious changes in the gross anatomy of the cerebellum are confirmed in reconstructions which define cell and fiber translocation. Thus, the spastic gene is compatible with differentiation of all cerebellar elements, but appears to alter interactions between cells, or between cells and the external milieu. Although all cell types are present in the mutant cerebellum, they fail to attain their proper positions along all three body axes.

Abstract
The potential retrograde changes that occur in the proximal segment of transected nerve fibers found in the region of the spinocervical tract (SCT) and in the region of the dorsal spinocerebellar tract (DSCT) after unilateral dorsolateral column (DLC) lesions were studied in kittens and adult cats. Nerve fibers in the region of the SCT and DSCT in the spinal segments caudal to the lesion were studied in transverse sections of Epon embedded material that had been fixed by vascular perfusion with a 4% buffered paraformaldehyde solution, post-fixed in osmium tetroxide, and stained with Azur II-methylene blue. T8 level DLC lesions in the 10-week old kitten resulted in a 14 to 25% decrease in mean fiber diameter in the SCT fibers (larger than or equal to 5 mu) of the T13 level. Retrograde fiber degeneration occurred in the small and large caliber fibers of the DSCT. A 15 to 30% decrease in mean fiber diameter occurred in the DSCT fibers (greater than or equal to 5 mu). The fiber density of the DSCT decreased by 20 to 30% and this could be correlated with a 20% loss of class C neurons (Loewy, '70) and a severe atrophy affecting the remaining 80% of the surviving class C neurons in the L3 segment. Mid-cervical DLC lesions in the 10-week old kitten resulted in a 10% decrease in mean fiber diameter in the SCT fibers (less than or equal to 5 mu), a 15% decrease in mean fiber diameter in the DSCT fibers (less than or equal to 5 mu), and no change in fiber density could be determined despite the finding that these lesions produced about a 10% loss of class C neurons. A T1 level lesion in a 20-week old kitten produced no change in the SCT fibers suggesting that the changes seen in the 10-week old kitten after midcervical lesions were probably age-dependent changes. A 20% decrease in mean fiber diameter (less than 5 mu) and a 6% decrease in fiber density was detected in the DSCT. T13-L1 level DLC lesions in the adult cats resulted in degeneration of some of the large and medium size fibers in the DSCT which was most noticeable at 20 to 25 days after surgery. DLC lesions did not cause degenerative changes in the SCT fibers 5 to 25 days after surgery.

Abstract
The spinal grey projects upon the contralateral superior colliculus via two overlapping pathways in the lateral funiculus. One, more ventrally placed, is the classical spinotectal tract, which crosses immediately in the spinal cord and remains crossed. The other, lying more dorsally, ascends homolaterally but is subject to delayed crossing in the brainstem (especially the intertectal) commissures to reach the contralateral colliculus. Both sets of fibers end only in the caudal half of the colliculus, predominantly in the stratum album intermedium. The projections from individual cord segments distribute in an ordered fashion as a series of transverse, overlapping bands, the cervical cord projecting most rostrally, the sacro-coccygeal most caudally. Additional fibers, which distribute with less marked topography, end in the lateral extreme of the stratum griseum profundum and stratum album profundum.

Abstract
A new silver impregnation technique for frozen and paraffin sections of formalin-fixed nervous tissue has been devised by modifying the Fink-Heimer14 and De Olmos-Ingram6 methods. The modified versions have been combined into a single staining procedure. Cobalt or lead nitrate are substituted for uranyl nitrate. Silver nitrate in the impregnating solution is replaced by silver lactate or protargol. This procedure results in a preferential impregnation of degenerating perikarya, dendrites, axons and synaptic endings. It affords a more complete impregnation of 'preterminal' axonal arborizations than previous methods. The method is effective for the demonstration of degenerating terminals in the rat cerebellar cortex. Emphasis has been laid on the usefulness of the method for the study of drug-induced CNS lesions.

Abstract
Two steers were fed leaves of plants of the family Zamiaceae, one Bowenia serrulata and the other, Macrozamia lucida.Degenerative lesions were demonstrated in the nerve fibres of the fasciculus gracilis and the dorsal spinocerebellar pathways.Two naturally affected animals from an area where m. lucida was grazed were also examined, and in these, degenerative lesions of the fasciculus gracilis were found.
