Excitatory Postsynaptic Potential: How Neurons Fire
EXCITATORY POSTSYNAPTIC POTENTIAL (EPSP) The Core Definition of EPSP The Excitatory Postsynaptic Potential (EPSP) represents a transient depolarization of the postsynaptic neuron membrane caused by the influx of positively charged ions. In its simplest form, an EPSP is a graded electrical potential that occurs when an excitatory neurotransmitter is released from the presynaptic terminal, binding […]
EXCITATORY FIELD
Introduction: Defining the Excitatory Field The concept of an excitatory field in neuroscience refers to the localized electrical activity that promotes the firing of a neuron, moving its membrane potential closer to the threshold required for generating an action potential. This phenomenon is predominantly characterized by the excitatory postsynaptic potential (EPSP), which is a temporary […]
