By looking at THC’s effect on a rat brain, the researchers showed that THC, the main psychoactive compound in marijuana, can produce highly rewarding effects in the front-most part of a region of the brain called the nucleus accumbens. The image is in the public domain.
The secretory pathway delivery of cannabinoid type 1 receptor is axonally based, and surface expressed CB1R is more stable in axons than dendrites.
More than 80% of parents reported significant or moderate improvements in their child's ASD symptoms following medical cannabis treatment, a new study reports.
Researchers evaluate the psychological and neurobiological impact of teen cannabis use. The findings, to be presented at the 13th Annual Canadian Neuroscience Meeting, will cover how cannabis contributes to cognitive impairments, psychosis and deficits in decision making in adolescents.
Schizophrenia risk may predict cannabis use, rather than the other way around, a new study reports.
Sibling study reveals moderate cannabis use during adolescence has adverse effects on cognitive function that cannot be explained by genetics or other environmental factors.
Researchers look to explore which cognitive functions are most affected by cannabis use, and how long the effect of the drug can last.
