Corticotropin-releasing factor and neuropeptide Y work in synchronized opposition to each other to remodel and rewire neurons in the amygdala as a response to stress. The process, researchers say, can be manually reversed to help relieve anxiety.
When hippocampal firing rates are high before exposure to a learning task, people are better able to successfully encode memory. Findings suggest the hippocampus may have a “ready to encode” mode that facilitates memory recall.
Age, sex, and gender influence the organization of the brain’s opioid system. Findings shed light on why there are significant differences between the opioid system on an individual level, and why some are more prone to developing opioid-linked patholo…
Researchers identified a distinct population of GABAergic neurons activated by general anesthetic in the central amygdala of mice. The findings point to central amygdala GABAergic neurons as a potential therapeutic target to alleviate chronic pain.
Study provides insight into the neural mechanisms of how prey animals use the sounds or actions of others to infer danger and respond defensively.
Increased levels of serotonin transporters in the amygdala may explain why some people are more prone to anxiety than others.
Chromosome 16p11.2 duplication impacts several different inhibitory neuron types that use GABA in brain areas that are dysfunctional in schizophrenia, including the prefrontal cortex, hippocampus, and amygdala. The chromosome 16p11.2 duplication also r…
Turning off kappa opioid receptors in the brain decreases the urge the binge drink. Findings suggest the kappa opioid receptor system is important not only for the negative state of withdrawal but also for driving binge drinking behaviors.
