Kind: research · Impact: low

## In brief

- Corticosteroid treatment dysregulates circadian rhythms in the rat perirhinal cortex, according to the study headline.
- The same treatment is reported to disrupt synaptic function in that brain region.

## Why it matters

The findings link corticosteroid exposure to changes in brain clock rhythms and synapses in a memory-related cortical area, which may matter for researchers studying how steroid treatments affect the brain. The source gives no further detail, and the work is in rats.
