Researchers at the University of Oxford, U.K., have discovered how the rate of exposure time to someone with COVID-19 contact relates to infection risk. They found that the duration of exposure to individuals with COVID-19 ...
In the brain, neurons communicate via neurotransmitters, which trigger electrical signals in downstream neurons by binding and activating specific receptors. Neurotransmitters are released through the fusion of synaptic vesicles, ...
