Star-shaped glial cells act as the brain's 'motherboard'

The transistors and wires that power our electronic devices need to be mounted on a base material known as a "motherboard." Our human brain is not so different—neurons, the cells that transmit electrical and chemical signals, ...

Cell death in retina helps tune our internal clocks

(Medical Xpress)—With every sunrise and sunset, our eyes make note of the light as it waxes and wanes, a process that is critical to aligning our circadian rhythms to match the solar day so we are alert during the day and ...

Study shows how brain cells shape temperature preferences

While the wooly musk ox may like it cold, fruit flies definitely do not. They like it hot, or at least warm. In fact, their preferred optimum temperature is very similar to that of humans—76 degrees F.

Less tau reduces seizures and sudden death in severe epilepsy

Deleting or reducing expression of a gene that carries the code for tau, a protein associated with Alzheimer's disease, can prevent seizures in a severe type of epilepsy linked to sudden death, said researchers at Baylor ...

Scientists describe the genetic signature of a vital set of neurons

Scientists at NYU Langone Medical Center have identified two genes involved in establishing the neuronal circuits required for breathing. They report their findings in a study published in the December issue of Nature Neuroscience. ...

A step forward in regenerating and repairing damaged nerve cells

A team of IRCM researchers, led by Dr. Frédéric Charron, recently uncovered a nerve cell's internal clock, used during embryonic development. The discovery was made in collaboration with Dr. Alyson Fournier's laboratory ...
