Slideshow provides detailed facts, animations, and videos of the transfer of information that propagates from one neuron to the next.

We're going to talk about how neurons in a neural network learn by getting their math adjusted, called backpropagation, and how we can optimize networks by finding the best combinations of weights to minimize error. [12:08]

Learn about two different types of neurotransmitter receptors - ionotropic and metabotropic. [6:36]

Synapses are where neurons contact and communicate with their target cells. This video explains the structure and types of synapses using diagrams. [6:50]

Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received through the dendrites, travel to...
