Abstract
According to rough estimates, at least one third of the population in developed countries suffers, to varying degrees, from certain forms of primary headache, the modern pharmacotherapy of which is not always effective and has a number of limitations. The non-pharmacological treatment of headache can be an alternative to the prescription of pharmacological agents and the only possible assistance option for patients developing drug-resistant cephalalgias. This review describes various methods of electrical neuromodulation that are used for the management of primary headaches. The authors provide information on current stages in implementation of implantable and non-invasive equipment into clinical practice, which makes possible electrical stimulations of peripheral nerves and of the sphenopalatine ganglion, as well as allows transcranial magnetic stimulation. Also the appearance and usage of portable electrical devices available on the world market are described, and mechanisms that can underlie anticephalgic action of neuromodulation therapy are discussed. Special attention is paid to the methods that are applied for electrostimulation of the vagus nerve and occipital nerves.

Abstract
BACKGROUND Buspirone, a partial agonist of the 5-HT1a receptor (5-HT1a R), owing to potential antinociceptive properties may be useful in treatment of abdominal pain in IBS patients. The pain-related effects of buspirone are mediated via the 5-HT1a Rs, specifically located within the ventrolateral medulla (VLM). The most animal studies of the 5-HT1a R involvement in pain control have been carried out with somatic behavioral tests. The 5-HT1a R contribution in visceral pain transmission within the VLM is unclear. The objective of our study was to evaluate the 5-HT1a R contribution in abdominal pain transmission within the VLM. METHODS Using animal model of abdominal pain (urethane-anaesthetized rats), based on the noxious colorectal distension (CRD) as pain stimulus we studied effects of buspirone (1.0-4.0 mg kg-1 , iv) on the CRD-induced VLM neuron and blood pressure responses as markers of abdominal pain before and after the 5-HT1a R blockade by antagonist, WAY 100,635. RESULTS The CRD induced a significant increase in VLM neuron activity up to 201.5 ± 18.0% and depressor reactions up to 68 ± 1.8% of baseline. Buspirone (1.0-4.0 mg kg-1 , iv) resulted in an inhibition of the CRD-induced neuron responses which were changed inversely with dose increase and decreased depressor reactions directly with dose increase. These effects were antagonized by intracerebroventricular WAY 100,635. CONCLUSION Buspirone exerts complex biphasic action on the pain-related VLM neuron activity inversely depending on dose. The final effect of buspirone depends on the functional balance between of activation the pre- and postsynaptic 5-HT1a Rs in mediating pain control networks.

Abstract
We have demonstrated that activation of 5-HT1A receptors with buspirone promotes visceral analgesia in awake dogs. The administration of 0.035 mg/kg (i.m.) of the drug caused depression of viscero-motor (contraction of the abdominal muscles) and pressor (increase in the heart rate) responses to noxious distension of the large intestine. An increase in the dose to 0.07 and 0.14 mg/kg did not enhance the antinociceptive effect of buspirone but triggered basal tachycardia. The obtained results provide evidence of the inhibitory role of 5-HT1A receptors in modulating visceral pain sensitivity and the possibility of an exciting effect of their activation on the cardiovascular system.

Abstract
The caudal ventrolateral medullary reticular formation is the first supraspinal level processing visce- ral nociceptive signals. In experiments on rats reactions of neurons of this zone to nociceptive stimulation of large intestine were examined and effects of selective blockade of 5-HT3-receptors on these reactions were assessed. According to the character or responses to nociceptive colorectal stimulation (CRS) the re- corded medullary cells were divided into three groups - excitated, inhibited and indifferent. Intravenous injection of 5-HT3-antagonist granisetron (1 and 2 mg/kg) as well as local application of the substance on medulla surface (1.25 and 2.5 nmole) suppressed dose-dependently background and evoked discharges of the reticular neurons excited by CRS but did not exert so much expressed influence on the cells inhibited by visceral nociceptive stimulation. Spike activity of the group of neurons indifferent to CRS under simi- lar conditions was of 5-HT3-independent character. The results obtained provide evidence that 5-HT3-re- ceptors mediate the facilitating effect of serotonin on the supraspinal transmission of abdominal nocicep- tive stimulus which, partly at least, is realized through selective activation of visceral nociceptive neurons of the medulla. The blocking of this mechanism may underlie the analgesic effect of 5-HT3-antagonists in a abdominal pain syndromes.

Abstract
Effects of millimeter-wave electromagnetic radiation (40 GHz frequency, 0.01 mW power) on the spontaneous fi ring of convergent neurons of the spinal trigeminal nucleus and their responses to electrical stimulation of the dura mater were studied in neurophysiological experiments on rats. Irradiation of the area of cutaneous receptive fields of spinal trigeminal nucleus reversibly inhibited both spontaneous discharges and activity induced by electrical stimulation of the dura mater. The second and third exposures to electromagnetic radiation with an interval of 10 min were ineffective. These results suggest that suppression of neuronal excitability in the spinal trigeminal ganglion can be a mechanism of the anti-migraine effects of electromagnetic radiation observed in clinical practice.

Abstract
BACKGROUND Migraine is a chronic neurological disorder characterized by episodes of throbbing headaches. Practically all medications currently used in migraine prophylaxis have a number of substantial disadvantages and use limitations. Therefore, the further search for principally new prophylactic antimigraine agents remains an important task. The objective of our study was to evaluate the effects of a fixed combination of dextromethorphan hydrobromide and quinidine sulphate (DM/Q) on activity of the spinal trigeminal neurons in an electrophysiological model of trigemino-durovascular nociception. METHODS The study was performed in 15 male Wistar rats, which were anaesthetized with urethane/α-chloralose and paralysed using pipecuronium bromide. The effects of cumulative intravenous infusions of DM/Q (three steps performed 30 min apart, 15/7.5 mg/kg of DM/Q in 0.5 mL of isotonic saline per step) on ongoing and dural electrical stimulation-induced neuronal activities were tested in a group of eight rats over 90 min. Other seven animals received cumulative infusion of equal volumes of saline and served as control. RESULTS Cumulative administration of DM/Q produced steady suppression of both the ongoing activity of the spinal trigeminal neurons and their responses to electrical stimulation of the dura mater. CONCLUSIONS It is evident that the observed DM/Q-induced suppression of trigeminal neuron excitability can lead to a reduction in nociceptive transmission from meninges to higher centres of the brain. Since the same mechanism is believed to underlie the pharmacodynamics of many well-known antimigraine drugs, results of the present study enable us to anticipate the potential efficacy of DM/Q in migraine.

Abstract
Neuroanatomical studies demonstrated the existence of direct descending projections from the insular cortex to the area of the solitary tract nucleus responsible for mediating the vagovagal reflexes of the proximal part of the gastrointestinal tract. These studies provided grounds for suggesting that one of the mechanisms mediating the influences of the insular cortex on stomach function may be modulation of its vagovagal reflex reactions, one of which is the antrofundal inhibitory reflex. Experiments on conscious dogs were performed to study the effects of electrical stimulation of the insular cortex on execution of the antrofundal gastric reflex in conditions of intermittent gastrointestinal tract activity during fasting. Stretching of the walls of the antral segment of the stomach during the active period of intermittent gastric activity led to suppression of contractions in the fundal segment. Electrical stimulation of the insular cortex was found to prolong this reflex reaction. Thus, one result of activation of the insular area of the cortex is enhancement of the inhibitory vagovagal gastric reflexes, in all probability occurring as a result of modulation of neurotransmission in the vagovagal reflex arc system.

Abstract
New data were obtained on modification of heterochromatin parameters in the nuclei of medulla oblongata neurons in Wistar rats after stimulation of the vagus nerve: decrease in the area of heterochromatin regions and redistribution of chromocenters within the neuronal nuclear system. It was concluded that realization of the viscero-visceral reflex is associated with rearrangement of chromatin in neurons involved in transmission of the corresponding information.

Abstract
Electrophysiological and neuroanatomical experiments on Wistar rats were performed to study the mechanisms of the modulatory influences of the amygdaloid nuclei on reflex motor activity in the stomach. Electrical stimulation of the central nucleus was accompanied by reproducible changes in the ongoing motor activity of the stomach in activity evoked by activation of the vagovagal reflex arc. The most marked, and predominantly inhibitory, effects were seen in response to stimulation of the medial part of the nucleus. Microinjections of the anterograde neuron marker Phaseolus vulgaris leucoagglutinin (PHA-L) into the central nucleus of the amygdala revealed the existence of direct descending projections from its dorsomedial part to the area containing cells of the vagosolitary complex, associated with performance of the vagovagal reflexes of the stomach. Electrical stimulation of this part of the central nucleus led to changes in neuron responses in the bulbar "gastric" center evoked by stimulation of the vagus nerve. These features may underlie one of the mechanisms of the amygdalar modulation of the reflex activity of the stomach.
