019 What is Summation (2 Types)

In this video, Leslie Samuel explains the concept of summation in neuroscience, focusing on how postsynaptic potentials add up to reach the threshold for an action potential. The video covers the basics of membrane potential and introduces two types of summation: temporal and spatial. Temporal summation involves repeated signals from the same neuron over time, while spatial summation involves signals from multiple neurons. The video concludes with a comparison of these summation types, providing a clear understanding of how they contribute to action potentials.
