Study: Neurons regulating reproductive hormone release have different activity in epileptic mice

Mice with epilepsy have altered patterns of neuron activity in the portion of the brain that controls the reproductive endocrine system, University of Illinois researchers report in a new study. Furthermore, the differences in neuron activity in female mice fluctuate across the reproductive cycle, the team found.

Researchers identify a new cause of chronic stress in the brain

In an international collaboration between MedUni Vienna, Semmelweis University in Budapest, the Karolinska Institute in Stockholm and Yale University in the USA, researchers have identified a new process in the brain that is responsible for the delayed stress response and the long-term effects of stress: with a delay of 10 minutes after the "danger", the area of the brain that reacts to stress and responsible for further action is activated via the cerebral fluid.

Study: Fox domestication linked to changes in gene activity in the pituitary gland

A study of foxes offers new insights into the brain changes that occur in wild canids as they become more tame, researchers report. The study links fox domestication to changes in gene activity in the pituitary gland, a brain center that kicks out hormones to regulate various bodily functions, including the stress response.
