Chronic stress alters how mice process sound, causing weaker reactions to softer noises, study finds.
Researchers from Ben-Gurion University found that chronic stress changes how mice process sound.
Under stress, mice showed weaker reactions to lower-decibel sounds but maintained strong responses to louder sounds.
This was linked to increased activity in certain brain cells that suppress reactions to sound.
The study, published in PLOS Biology, suggests that chronic stress can alter responses to neutral stimuli like everyday sounds.
