Surprising effects of oxytocin on cocaine addiction

In men with a history of childhood trauma, oxytocin reduced the activity within the amygdala and cravings for cocaine. Women who were addicted to cocaine and had experienced childhood trauma showed an increase in amygdala activity following exposure to oxytocin.

Study sheds light on link between cannabis, anxiety and stress

A naturally occurring molecule produced by the brain activates endocannabinoid receptors, protecting against stress by reducing anxiety-producing connections between the amygdala and the prefrontal cortex. The findings may help explain why people turn to marijuana when they feel anxious or stressed.

Adolescent drinking increases anxiety and alcohol abuse risk later in life

Teenage binge drinking is linked to altered gene expression in the brain, specifically the central nucleus of the amygdala. Adolescent rats exposed to alcohol had increased levels of miR-137, resulting in lower expression of proteins essential for healthy neuron growth. During adulthood, these rats displayed higher levels of anxiety and an increased preference for alcohol consumption.

How brain injury can lead to post-traumatic stress disorder

Traumatic brain injury caused five times as many neurons in the amygdala to be active during white noise exposure in rats. Altered sensory processing within subcortical sensory-emotional networks following TBI impacts the facilitation of traumatic memory and may contribute to the development of PTSD.
