Stress, unaccompanied by signs of post-traumatic stress disorder, is known to decrease grey matter volume (GMV) in the anterior cingulate cortex (ACC) and hippocampus but not the amygdala in humans. We sought to determine if this was the case in stressed mice using high-resolution magnetic resonance imaging (MRI) and to identify the cellular constituents of(More)
Stress has been linked to the pathogenesis of schizophrenia. Genetic variation in neuregulin 1 (NRG1) increases the risk of developing schizophrenia and may help predict which high-risk individuals will transition to psychosis. NRG1 also modulates sensorimotor gating, a schizophrenia endophenotype. We used an animal model to demonstrate that partial genetic(More)
The evidence base for the use of medical cannabis preparations containing specific ratios of cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) is limited. While there is abundant data on acute interactions between CBD and THC, few studies have assessed the impact of their repeated co-administration. We previously reported that CBD inhibited or potentiated(More)
Schizophrenia is thought to arise due to a complex interaction between genetic and environmental factors during early neurodevelopment. We have recently shown that partial genetic deletion of the schizophrenia susceptibility gene neuregulin 1 (Nrg1) and adolescent stress interact to disturb sensorimotor gating, neuroendocrine activity and dendritic(More)
INTRODUCTION The schizophrenia susceptibility gene neuregulin 1 (NRG1) confers vulnerability to the neurobehavioural eff ects of cannabinoids differently across sexes. Male but not female Nrg1 heterozygous (HET) mice display facilitation of prepulse inhibition (PPI) to acute Δ⁹-tetrahydrocannabinol (THC) exposure compared to WT controls. We aim to observe(More)
