Discover how magnesium deficiency affects 45% of Americans, causing symptoms from irregular heartbeats to sleep issues, plus ...

Brain ion channels have molecular memory, changing shape after repeated signals, affecting neurotransmitter release.

When an action potential reaches the axon terminal, it triggers calcium influx, prompting vesicles to release neurotransmitters into the synaptic cleft. These chemical messengers such as dopamine ...

PDNP-mediated NIR stimulation caused clear increases in calcium signaling. When acetylcholine breakdown was inhibited, this response was prolonged, indicating sustained neurotransmitter release. When ...

The team then used imaging techniques to measure acetylcholine levels and calcium influx. Calcium is essential for neurotransmitter release. In the eIF4E mice, acetylcholine binding to dopamine axons ...

A mix of neurotransmitters — chemical messengers of the nervous system — could be behind the phenomenon, Richard said, although researchers are still working to confirm the exact mechanism by ...

Calcium channels play a central role in pain signaling, in part through the release of neurotransmitters such as glutamate and GABA -- "the currency of the pain signal," according to Rajesh Khanna ...

Distinct synaptic vesicle pools, released by different calcium channels, could be used to tune the speed, voltage-dependence, and quantal content of neurotransmitter release. Here, we demonstrate in C ...

Opioid receptor activation enhances potassium channel (KV) and inhibits calcium channel (CaV) function, reducing neurotransmitter release or producing changes in postsynaptic excitability. Opioid ...

All membrane fusion reactions proceed through an initial fusion pore, including calcium-triggered release of neurotransmitters and hormones. Expansion of this small pore to release cargo is ...

She has just received $1.9 million from the National Eye Institute for her project titled, "Dynamics of calcium signals control neurotransmitter release in retinal ribbon Synapses". The goal of Dr ...
