Neural circuit that drives physical responses to emotional stress discovered

Researchers have identified a brain circuit that drives physical response to emotional stress. The circuit begins in the dorsal peduncular cortex and dorsal tenia tecta, before sending signals to the hypothalamus. The findings could help with the development of treatments for panic disorders and PTSD.

What stress does to the brain

A new study sheds light on how the brain changes as a result of chronic stress. Selective noradrenaline release rewires connectivity patterns between different brain regions. Activity in the amygdala and networks that process sensory stimuli increased.

Targeting key gene could help lead to down syndrome treatment

Using stem cells from candidates with Down syndrome to create an organoid, and employing mouse models, researchers pinpoint a gene linked to memory impairments and cognitive problems in Down syndrome. Inhibiting the OLIG2 gene leads to cognitive and memory improvements in mouse models of Down. Researchers hope their findings lead to an in utero treatment that targets the gene and helps reverse abnormal brain development.

Estrogen Made by Neurons Important to Memory Making

Researchers report estrogen may play a significant role in synaptic plasticity and memory formation. The study reports mice whose neurons did not produce estrogen have impairments in spatial reference memories, recognition and contextual fear memories. Restoring estrogen levels assisted in reversing the memory impairments, the study revealed.

Placental Accumulation of Flame Retardant Chemical Alters Serotonin Production in Rat Offspring

A new study reports on a link between exposure to a flame retardant mixture used in foam based furniture and the disruption of normal placenta function in rats. The placental disruption alters the production of serotonin in offspring, researchers report.
