The brain’s chatter has always been partly out of reach, with electrical spikes easy to record but the chemical whispers ...

It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

HOUSTON – (Jan. 18, 2023) – The sensory organs that allow us to walk, dance and turn our heads without dizziness or loss of balance contain specialized synapses that process signals faster than any ...

Parkinson's and Alzheimer's diseases are the two most common neurodegenerative disorders, affecting millions of people worldwide. Published in the Journal of Neuroscience, new research from the ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...

A technology called single-molecule imaging has enabled scientists at the University of Maryland to identify the architecture of synapses – the tiny junctions that connect neurons together – and ...

Neurotransmission, or synaptic transmission, corresponds to the movement of signals between neurons, permitting the transmission of information through the proliferation of action potentials. This ...

Interactions of two voltage-gated calcium channels and a pump enable separate control of exocytosis and endocytosis at chemical synapses. Chemical synapses transmit information within the nervous ...
