Neurons Vulnerable to Alzheimer’s Identified

Researchers identified a subset of neurons in the mammillary body of the hypothalamus which are susceptible to hyperactivity and neurodegeneration. This damage often leads to memory impairment associated with Alzheimer's disease. Treating these neurons with a drug currently used in the treatment of epilepsy reverses memory impairments caused by this hyperactivity and neurodegeneration.

Small Differences in Mom’s Behavior May Show Up in Child’s Epigenome

A mother's social interaction with her child, especially if her behavior is cold or awkward, correlated with a small increase in methylation of the child's NR3C1 gene. The NR3C1 is involved in the regulation of the HPA-axis which plays a critical role in stress response and the production of cortisol.

When Chronic Stress Activates These Neurons, Behavioral Problems Like Loss of Pleasure and Depression Result

Anhedonia and depression arise when POMC neurons in the arcuate nucleus of the hypothalamus become hyperactive as a result of chronic stress. Reducing the activity also reduces feelings of depression and loss of pleasure.
