Past and Future of Analog-Digital Modulation of Synaptic Transmission [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2019
Action potentials (APs) are generally produced in response to complex summation of excitatory and inhibitory synaptic inputs. While it is usually considered as a digital event, both the amplitude and width of the AP are significantly impacted by the ...
