Researchers from Kyushu University have developed an innovative technique to non-invasively measure two key signals, membrane voltage and intracellular calcium levels, at the same time, in neurons of ...

Nonlinear responses of individual neurons are both experimentally established and considered fundamental for the functioning of neuronal circuitry. Consequently, one may envisage the collective ...

Neurons carry vital signals all over our body, and the nervous system controls many crucial functions, from breathing to digestion to movement. It’s long been thought that neurons were mostly powered ...

Seminal positron emission tomography (PET) functional imaging studies in humans by Fox and Raichle revealed that, during sensory activation, glucose utilization and oxygen consumption are uncoupled, ...

The brain contains many cell types, from the prominent neurons to the lesser-known microglia. The latter are integral to the brain's immune system and play a crucial role as the brain's cleanup crew.

Different brain regions are connected by—and interact through—networks of neurons. But the extent to which neuronal wiring drives shared function between these different regions is not well understood ...

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 ...

BOSTON, Mass. (July 15, 2024)—A groundbreaking study conducted at the lab of Beth Stevens, PhD, at Boston Children’s Hospital has revealed that an immune protein impacts neuronal protein synthesis in ...

A new Yale study has revealed that neurons — the energy-hungry cells that connect and direct activity in the brain — are equipped with “backup batteries” that kick in to keep the brain running during ...

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 ...

The rapid advancement of artificial intelligence (AI) and machine learning systems has increased the demand for new hardware components that could speed up data analysis while consuming less power. As ...

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 ...
