EPSPs (Excitatory Post-Synaptic Potentials) are important in neural communication and can be described as follows:
- EPSPs are due to an influx of sodium ions.
- EPSPs occur at chemically gated channels.
- EPSPs depolarize the cell, making it more likely to generate an action potential.
So, the correct choices for EPSPs in the given options are:
a. are due to an influx of sodium ions
b. occur at chemically gated channels
e. depolarize the cell
These characteristics define the role and mechanism of EPSPs in neuronal signaling.
