Stress physically alters communication in the brain.
Astrocytes, which are brain cells that regulate neuronal communication, show long-term degradation from stress.
In research with mice, Liu’s study finds that even a single stressful event can quickly cause long-lasting changes to an astrocyte.
When experiencing stress, the astrocytes shrink away from synapses resulting in disruption of neural communication. Synapses are structures that allow information to pass from one cell to another via neurotransmitters.
