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 ...

Neurons are the specialized cells that allow our bodies to transmit impulses, like factories that process inputs. They send signals that help us catch a ball, recognize a favorite song or pull our ...

Synaptic vesicles act as the brain’s chemical couriers, transporting neurotransmitters between cells. When a nerve impulse arrives, these vesicles fuse with the neuron’s membrane and release their ...

The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but ...

A new study probing quantum phenomena in neurons as they transmit messages in the brain could provide fresh insight into how our brains function. Our brains process information via a vast network ...

Alzheimer's disease and Parkinson's disease, along with stroke, are among the top three neurodegenerative disorders, characterized by the malfunction and progressive degeneration of neurons, the nerve ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...
