Seeing what the eyes are telling us

Extra! Extra!

At the lab of Christopher Pack of the Montreal Neurological Institute and Hospital, the focus is on visual perception, specifically, how neurons communicate with one another to decipher what the eyes are seeing. Focusing on the visual cortex, the “Pack Lab” uses microelectrode recordings to listen to individual neurons as they talk to their neighbours.

The brain gives up more secrets


New research led by the Research Institute of the McGill University Health Centre demonstrates that brain cells, known as astrocytes, which play fundamental roles in nearly all aspects of brain function, can be adjusted by neurons in response to injury and disease. The discovery, which shows that the brain has a far greater ability to adapt and respond to changes than previously believed, could have significant implications on epilepsy, movement disorders, and psychiatric and neurodegenerative disease.
