Abstract
Autism is a complex condition with many traits, including differences in auditory sensitivity. Studies in human autism are plagued by the difficulty of controlling for aetiology, whereas studies in individual rodent models cannot represent the full spectrum of human autism. This systematic review compares results in auditory studies across a wide range of established rodent models of autism to mimic the wide range of aetiologies in the human population. A search was conducted in the PubMed and Web of Science databases to find primary research articles in mouse or rat models of autism which investigate central auditory processing. A total of 88 studies were included. These used non-invasive measures of auditory function, such as auditory brainstem response recordings, cortical event-related potentials, electroencephalography, and behavioural tests, which are translatable to human studies. They also included invasive measures, such as electrophysiology and histology, which shed insight on the origins of the phenotypes found in the non-invasive studies. The most consistent results across these studies were increased latency of the N1 peak of event-related potentials, decreased power and coherence of gamma activity in the auditory cortex, and increased auditory startle responses to high sound levels. Invasive studies indicated loss of subcortical inhibitory neurons, hyperactivity in the lateral superior olive and auditory thalamus, and reduced specificity of responses in the auditory cortex. This review compares the auditory phenotypes across rodent models and highlights those that mimic findings in human studies, providing a framework and avenues for future studies to inform understanding of the auditory system in autism.

Nakajima M, Watanabe T, Aoki R, Shimizu R, Okuyama S, Furukawa Y. Phenotypes associated with psychiatric disorders are sex-specific in a mutant mouse line. Brain Res 2016; 1652:53-61. [PMID: 27693417 DOI: 10.1016/j.brainres.2016.09.037] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Revised: 07/31/2016] [Accepted: 09/27/2016] [Indexed: 11/25/2022]
Abstract
Wnt1-Cre- and Wnt1-GAL4 double transgenic (dTg) mice are used to study neural crest cell lineages by utilizing either the Cre/loxP or the GAL4/UAS system. We have previously shown that these mice exhibit behavioral abnormalities that resemble certain behaviors of psychiatric disorders and histologic alterations in the cholinergic and glutamatergic systems in the brain. The objective of the current study was to extend the behavioral analyses in these mice and to determine whether there were any sex-specific differences in the prevalence or severity of these behaviors. In the present study, we demonstrate additional behavioral abnormalities in dTg mice, such as increased locomotor activity, decreased social behavior, and an increased frequency in vertical jumping. Of these, the proclivity for vertical jumping was observed only in male dTg mice. In contrast, MK-801 administration induced increased locomotion in only female dTg mice. Furthermore, the concentrations of prolactin in the sera and oxytocin in the hypothalamus were both reduced only in female dTg mice, compared to controls. These sex-dependent behavioral and hormonal abnormalities in the dTG mice suggest that the phenotype of certain psychiatric disorders may be influenced by both genetic and sex-specific factors.
