Definitions:

Sodium Channels

Protein channels in cell membranes that allow sodium ions to flow into or out of a cell, crucial for processes such as the generation of electrical signals in neurons.

EPSPs

Stands for Excitatory Postsynaptic Potentials, which are temporary increases in neuron membrane potential, making it more likely to fire an action potential.

Temporal Summation

Addition of one graded potential to another that occur close in time.

Spatial Summation

Spatial summation refers to the process where multiple synaptic inputs, predominantly from separate neurons, combine within a single neuron, potentially leading to an action potential if threshold is reached.
