Saturated fatty acid levels rise in the brain during the formation of new memories, researchers say. The highest levels of saturated fatty acids were found in the amygdala, an area of the brain associated with fear and emotional memories.
The apical intercalated cell cluster (apITC), a specialized portion of inhibitory circuitry in the amygdala, has rich connectivity and plays a unique role in modulating synaptic plasticity.
A new study sheds light on how highly sensitive people process information. After experiencing something emotionally evocative, brain activity displayed a depth of processing while at rest. Depth of processing is a key feature of high emotional sensitivity.
A new study reveals activity in the amygdala remains consistent when a person views neutral stimuli following viewing negative stimuli. The persistent activity increased negative mood and decreased positive feelings.
Following exposure to visual stimuli, the neurons activated by the stimuli remain more active during subsequent sleep. Sleep is vital for these neurons to connect an emotional or fearful memory to a sensory event.
