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 ...
Chemical synapses transmit information within the nervous system. When a presynaptic cell is electrically excited, synaptic vesicles fuse with the presynaptic membrane causing messenger substances ...
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 ...
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 ...
