Tau proteins play an important role in our normal brain function, mainly by helping to stabilize neurons in the brain. But in Alzheimer’s disease, tau proteins can misfold and tangle inside neurons.

The cerebral cortex, the brain's outermost region responsible for higher cognitive functions, depends on a highly ordered, layered structure. Its proper development requires newly generated neurons to ...

Brain functions stem from and rely on electrical signals created and propagated by neurons. As such, scientists measure electrical signals to study neuronal function at both single-cell and systemic ...

A clearance mechanism involving microglia has been known to relieve neurons of toxic protein aggregates such as those associated with Alzheimer’s disease and Parkinson’s disease. Unfortunately, this ...

A new McGill University study has found a direct link between age-related declines in neuron activity in the cerebellum and worsening motor skills, including gait, balance and agility. While it is ...

A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

An EEG (electroencephalogram) is a painless test that uses small sensors placed on the scalp to measure the brain's ...

Fluctuations in brain activity, also known as neural variability, enable us to be flexible in adjusting our behavior to the current situation. A new study shows that neural variability increases ...
