Neurobiologists Uncover how Stress turns into Fear in the Brain in Conditions such as PTSD

Our nervous systems are naturally wired to sense fear. Whether prompted by the eerie noises we hear alone in the dark or the approaching growl of a threatening animal, our fear response is a survival mechanism that tells us to remain alert and avoid dangerous situations.Read More

Neurobiologists Identify a New Gene important for Healthy Daily Rhythms

Loss of this gene affects daily behavior, disrupting ~24-hour sleep-wake cycles. Life is organized on a 24-hour schedule. Central to this regular rhythm is the circadian clock, timekeepers that are present in virtually every organ, tissue and cell type. When a clock goes awry, sleep disruption or a variety of diseases can result.

A recent Northwestern University discovery could help in understanding how this clock is linked to daily cycles. A team of neurobiologists has identified a new gene, called Tango10, that is critical for daily behavioral rhythms. This gene is involved in a molecular pathway by which the core circadian clock (the “gears”) controls the cellular output of the clock (the “hands”) to control daily sleep-wake cycles.

While the study was done using the fruit fl...
