Field EPSP
The field EPSP (engl. Field EPSP) is in the neurobiology the name for a electric potential , which is at a neuronal excitation extracellularly can be derived and measure. It is formed by ion currents that flow through the cell membrane of the nerve cell . The field EPSP is characterized by an initial negative deflection in the monosynaptic evoked field potential which, when derived, reflects the primary synaptic activation of the derived neuron population.
It is the extracellular counterpart of the excitatory or excitatory postsynaptic potentials (EPSP) triggered on the individual neurons when stimulated .
