Researchers identify how cells control calcium influx
(Medical Xpress)—When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through which these molecules enter the cells. Until now, the "stop" signal mechanism that cells ...

Alzheimer's disease is associated with removal of the synaptic protein ADAM10
Alzheimer's disease is characterized by the accumulation of neurotoxic β-amyloid peptide (A-beta). ADAM10, a protein that resides in the neural synapses, has previously been shown to prevent the formation of A-beta.

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 ...
