Vulnerability in early life to changes in the rearing environment plays a crucial role in the aetiopathology of psychiatric disorders.

The results suggest that the frontal cortex and amygdala undergo structural remodelling induced by the stress of maternal separation and isolation, which alters behavioural and physiological responses in adulthood, including anxiety, memory and other cognitive processes.

Consequences of Post-Weaning Social Isolation on Anxiety Behavior and Related Neural Circuits in Rodents

Overall, the majority findings suggest that post-weaning social isolation that encompasses pre-adolescence produces long-lasting alterations to anxiety behavior, while measures of monoaminergic activity in various limbic regions during social isolation suggest alterations to dopamine and serotonin systems.

Neurobehavioural sequelae of social deprivation in rodents revisited: Modelling social adversity for developmental neuropsychiatric disorders

The early development of the paradigm by which rats were reared post-weaning in social isolation is described and compared with other early experience manipulations, and the specification of the neural and behavioural phenotype of the isolate is brought up-to-date.

Early Adolescent Emergence of Reversal Learning Impairments in Isolation-Reared Rats

The putative time course of reversal learning deficits in isolation-reared rats was examined and it was shown that isolation rearing of rats may offer a unique model to examine the ontogeny of behavioral and neurobiological alterations that may be relevant to preclinical models of prodromal psychosis.

Potential role of serotonin1A receptors in post-weaning social isolation-induced abnormal behaviors in rodents.

It is found that serotonin (5-HT)(1A)-receptor ligands attenuate abnormalities in social isolation-reared mice, suggesting the pharmacological role of the receptor in treatment of psychiatric disorders.

Influence of Postweaning Social Isolation in the Rat on Brain Development, Conditioned Behavior, and Neurotransmission

The effects of rearing rats from weaning in social isolation are reviewed and some recent results indicating hippocampal dysfunction are reported, which should improve knowledge of how environmental events may alter brain development and function, and play a role in the development of neuropsychiatric disorders.

Behavioural and neurochemical effects of early social deprivation in the rat

The behavioural and neurochemical sequelae of rearing in early social isolation are reviewed, and in vivo measurement of amine activity in isolates shows elevations in dopamine concentration in both the nucleus accumbens (ventral striatum) and the caudate-putamen.

Specific abnormalities in serotonin release in the prefrontal cortex of isolation-reared rats measured during behavioural performance of a task assessing visuospatial attention and impulsivity

These findings highlight a rather specific deficit in 5-HT release in the prefrontal cortex of isolation-reared rats, although this appears not to affect visual attentional function.

Abnormalities of presynaptic protein CDCrel‐1 in striatum of rats reared in social isolation: relevance to neural connectivity in schizophrenia

Altered levels of the septin CDCrel­1 in isolation‐reared rats may contribute to changes in neuronal connectivity and neurotransmission, and suggest a potential role for CDCrel‐1 in schizophrenia related to chromosome 22q11 deletion syndrome.

Effect of isolation rearing on pre‐ and post‐synaptic serotonergic function in the rat dorsal hippocampus

Isolation rearing in the rat results in hippocampal dysfunction, including reduced serotonergic and enhanced muscarinic activity of some neurones, which may in part underlie the behavioural consequences of isolation relevant to human developmental disorders.

Chronic (–)-Deprenyl Administration Attenuates Dendritic Developmental Impairment Induced by Early Social Isolation in the Rat

Dendritic quantification of the Golgi-Cox-Sholl-stained neurons indicated that chronic (–)-deprenyl administration partially compensated the dendritic growth impairment induced by social isolation.
