Regulation Of Emotion

The medial prefrontal cortex (mPFC) is a crucial cortical region that integrates information from numerous cortical and subcortical areas and converges updated information to output structures. It plays essential roles in the cognitive process, regulation of emotion, motivation, and sociability. Dysfunction of the mPFC has been found in various neurological and psychiatric disorders, such as depression, anxiety disorders, schizophrenia, autism spectrum disorders, Alzheimer’s disease, Parkinson’s disease, and addiction. In the present review, we summarize the preclinical and clinical studies to illustrate the role of the mPFC in these neurological diseases.

AbstractThe aim of this study was to identify the sequence mutations in the Neurexin 1 (NRXN1) gene that has been considered as one of the strong candidate genes. A total of 30 children and adolescents (aged 3-18) with non syndromic autism were enrolled this study. Sequencing of the coding exons and the exon-intron boundaries of the NRXN1 gene was performed. Two known mutations were described in two different cases. Heterozygous S14L was determined in one patient and heterozygous L748I was determined in another patient. The S14L and L748I mutations have been described in the patients with autism before. Both of these mutations were inherited from their father. In this study, two of 30 (6.7%) autism spectrum disorder (ASD) patients carrying NRXN1 gene mutations were detected. It indicates that variants in the NRXN1 gene might confer a risk of developing nonsyndromic ASD. However, due to the reduced penetrance in the gene, the causal role of the NRXN1 gene mutations must be evaluated carefully in all cases.

The Social

As a frontal node in the primate social brain, the medial prefrontal cortex (MPFC) plays a critical role in coordinating one's own behavior with respect to that of others. Current literature demonstrates that single neurons in the MPFC encode behavior-related variables such as intentions, actions, and rewards, specifically for self and other, and that the MPFC comes into play when reflecting upon oneself and others. The social moderator account of MPFC function can explain maladaptive social cognition in people with autism spectrum disorder, which tips the balance in favor of self-centered perspectives rather than taking into consideration the perspective of others. Several strands of evidence suggest a hypothesis that the MPFC represents different other mental models, depending on the context at hand, to better predict others’ emotions and behaviors. This hypothesis also accounts for aberrant MPFC activity in autistic individuals while they are mentalizing others. Expected final online publication date for the Annual Review of Neuroscience, Volume 44 is July 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

The review presents an analysis of the mechanisms of iron effect on the brain development. The importance of iron deficiency in the perinatal period is considered as a risk factor for the development of neuropsychiatric disorders in children with autism spectrum disorders (ASDs). Possible causes of sideropenia are discussed; data on haematological and biochemical parameters characterizing iron metabolism in children with ASDs are presented. The demand for studying the role of iron metabolism imbalance in the development of neuropsychiatric disorders in order to clarify pathogenetic mechanisms of ASDs and to determine methods for their correction is emphasized.
