Sensory attenuation deficit and auditory hallucinations in schizophrenia: a causal mechanism or a risk factor? Evidence from meta-analyses on N1 ERP-EEG component.
Sensory attenuation (SA), the dampened perception of self-generated sensory information, is typically associated with reduced ERP signals, like for the N1 component of auditory ERPs. SA, together with efficient monitoring of intentions and actions, should facilitate the distinction between self-generated and externally-generated sensory events, optimizing the interaction with the world.According to many, SA is deficient in schizophrenia. The question arises whether altered SA reflects a sufficient mechanism to explain positive symptoms like auditory hallucinations. (Source: Biological Psychiatry)

Individual differences in volitional social self-administration and motivation in male and female mice following social stress
A key challenge in developing treatments for neuropsychiatric illness is the disconnect between preclinical models and the complexity of human social behavior. We integrate voluntary social self-administration into a rodent model of social stress, as a platform for the identification of fundamental brain and behavior mechanisms underlying stress-induced individual differences in social motivation.

Disrupted maturation of white matter microstructure after concussion is associated with internalizing behavior scores in female children
Some children, particularly females, who experience concussions develop long-lasting emotional and behavioral problems. Establishing the potential contribution of pre-existing behavioral problems and disrupted white matter maturation has been challenging due to a lack of pre-injury data.

The Microbiome at the Interface of the Exposome and Risk for Psychiatric Disorders
The microbiome is emerging as a key modifier of brain function and behavior during homeostasis and in conditions related to brain disorders. There is a concomitant awareness that the exposome —representing all the environmental exposures of an individual across the lifespan—has profound influences on health and risk for neurological and neuropsychiatric disease. With the microbiome situated at the interface of environmental exposures and their impacts on the host, research directed a t uncovering how the microbiome responds to various environmental factors experienced at different stages of life could yield new mechani...

Guide for Authors
Biological Psychiatry, founded in 1969, is an official journal of the Society of Biological Psychiatry and the first in the Biological Psychiatry family of journals. Companion titles include Biological Psychiatry: Cognitive Neuroscience and Neuroimaging and Biological Psychiatry: Global Open Science. The Society ’s purpose is to promote excellence in scientific research and education in fields that investigate the nature, causes, mechanisms, and treatments of disorders of thought, emotion, and behavior.

Individualized texture similarity network in schizophrenia
Structural covariance network disruption has been considered an important pathophysiological indicator for schizophrenia. Here, we introduced a novel individualized structural covariance (ISCN) measure named texture similarity network (TSN) and hypothesized that TSN could reliably reveal unique inter-subject heterogeneity and complex dysconnectivity patterns in schizophrenia.

Brain structural and functional damage network localization of suicide
Extensive neuroimaging research on brain structural and functional correlates of suicide has produced inconsistent results. Despite increasing recognition that damage in multiple different brain locations that causes the same symptom can map to a common brain network, there is still a paucity of research investigating network localization of suicide.

Evening Chronotypes With Depression Report Poorer Outcomes of Selective Serotonin Reuptake Inhibitors: A Survey-Based Study of Self-Ratings
Preliminary evidence suggests that evening chronotype is related to poorer efficacy of selective serotonin reuptake inhibitors. It is unknown whether this is specific to particular medications, self-rated chronotype, or efficacy. (Source: Biological Psychiatry)
