The trial-to-trial variability of neuronal responses and the correlated response variability among neurons are modulated by visual stimulus size in a manner that depends on cortical layer, suggesting ...
A new McGill University study has found a direct link between age-related declines in neuron activity in the cerebellum and ...
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 ...
Other cells, such as glial cells, support the function of neurons. Neuroscience has often painted glial cells as the glue ...
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 ...
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 ...

Brain activity grows increasingly variable during development before stabilizing in adolescence, study shows
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 ...
Scientists have shown that specialized cells involved in how the body responds to insulin are activated in the brain after exercise, suggesting that physical activity may directly improve brain ...
