Removing a brain area and its impact on tidal rhythms in mangrove crickets
AI simplified
Abstract
Surgical removal of the pars intercerebralis decreased the proportion of mangrove crickets exhibiting a circatidal rhythm.
- More than half of the crickets displayed arrhythmic activity after the removal of the pars intercerebralis.
- Surgical removal of regions around the pars intercerebralis similarly affected locomotor activity.
- The findings indicate that the pars intercerebralis and its surrounding regions may play a crucial role in both circadian and circatidal rhythms.
- There may be a common neural or hormonal pathway in the pars intercerebralis and surrounding regions that influences both rhythmic patterns.
