Study sheds light on molecular underpinnings of long-term memory

On a late summer day in 1953, a young man who would soon be known as patient H.M. underwent experimental surgery. In an attempt to treat his debilitating seizures, a surgeon removed portions of his brain, including part of ...

Astrocytes identified as master 'conductors' of the brain

In the orchestra of the brain, the firing of each neuron is controlled by two notes—excitatory and inhibitory—that come from two distinct forms of a cellular structure called synapses. Synapses are essentially the connections ...

Discovery of a new key player in long-term memory

A McGill-led multi-institutional research team has discovered that during memory consolidation, there are at least two distinct processes taking place in two different brain networks—the excitatory and inhibitory networks. ...

Calcium channel subunits play a major role in autistic disorders

The ability of the human brain to process and store information is determined to a large extent by the connectivity between nerve cells. Chemical synapses are very important in this context as they constitute the interface ...
