A new study reveals how the brain determines whether a smell is pleasant or revolting, highlighting the role of the amygdala and two genetically distinct cell types that can assign either positive or negative value to odors. This discovery could lead to treatments for anxiety, PTSD, or sensory disorders.
Researchers found that meditation led to changes in activity in the amygdala and hippocampus, key brain regions involved in emotional regulation and memory. The study may help explain the positive impact of meditation on memory and emotional regulation.
