TLDR
The results suggest that heavy cannabis consumption in adolescence may induce subtle alterations in the emotional circuit in female rats, ending in depressive-like behavior, whereas male rats show altered sensitivity to rewarding stimuli.About:

Persistent sexually dimorphic effects of adolescent THC exposure on hippocampal synaptic plasticity and episodic memory in rodents
TL;DR: In this paper, a 14-day course of daily Δ9-tetrahydrocannabinol treatments administered to adolescent rats and mice (aTHC) leads to profound but selective deficits in synaptic plasticity in two axonal systems in female, and to lesser extent male, hippocampus as assessed in adulthood.

Transcriptomic Changes and the Roles of Cannabinoid Receptors and PPARγ in Developmental Toxicities Following Exposure to Δ9-Tetrahydrocannabinol and Cannabidiol.
TL;DR: In this article, larval zebrafish (Danio rerio) were used to measure THC and CBD-mediated changes on transcriptome and the roles of cannabinoid receptors (Cnr) 1 and 2 and peroxisome proliferator activator receptor γ (PPARγ) in developmental toxicities.

Altered subjective reward valuation among female heavy marijuana users.
Kathryn R. Hefner,Mark J. Starr +1 more
TL;DR: The results suggest sex differences in sensitivity to high risk rewards may be one pathway contributing to severer consequences of heavy marijuana use among women.

Molecular Basis of Cannabis-Induced Schizophrenia-Relevant Behaviours: Insights from Animal Models
Rose Chesworth,Tim Karl,Tim Karl +2 more
TL;DR: Animal models indicate several molecular mechanisms by which chronic cannabinoids contribute to schizophrenia-relevant neural and behavioural change, and it is likely that a number of these mechanisms are simultaneously impacted by chronic cannabinoids, thereby increasing schizophrenia risk in individuals who use cannabis.

Cognitive Development and Cannabis Use in Adolescents.
Alessandro Frolli,Maria Carla Ricci,Antonella Cavallaro,Agnese Lombardi,Antonia Bosco,Francesca Di Carmine,Francesca Felicia Operto,Luisa Franzese +7 more
TL;DR: In this article, the authors investigated how global cognitive functions can be affected by the frequency of cannabinoid consumption in different categories of consumers (chronic, occasional, and non-users), through the evaluation of executive functions.

The adolescent brain and age-related behavioral manifestations
TL;DR: Developmental changes in prefrontal cortex and limbic brain regions of adolescents across a variety of species, alterations that include an apparent shift in the balance between mesocortical and mesolimbic dopamine systems likely contribute to the unique characteristics of adolescence.
Journal ArticleDOI
Behavioural despair in rats: a new model sensitive to antidepressant treatments.
TL;DR: Positive findings with atypical antidepressant drugs such as iprindole and mianserin suggest that the method may be capable of discovering new antidepressants hitherto undetectable with classical pharmacological tests.

Critical periods of vulnerability for the developing nervous system: evidence from humans and animal models.
Deborah C. Rice,Stan Barone +1 more
TL;DR: Of critical concern is the possibility that developmental exposure to neurotoxicants may result in an acceleration of age-related decline in function, and the fact that developmental neurotoxicity that results in small effects can have a profound societal impact when amortized across the entire population and across the life span of humans.

The use of a plus-maze to measure anxiety in the mouse
TL;DR: The plus-maze appears to be a useful test with which to investigate both anxiolytic and anxiogenic agents.

The Mesolimbic Dopamine Reward Circuit in Depression
TL;DR: It is proposed that the NAc and VTA contribute importantly to the pathophysiology and symptomatology of depression and may even be involved in its etiology.
