Document Summary
You may wish to skip this and the next two lectures if you have a background in. If the brain is a stage, the undeniable star is a neuron. Neurons are tiny (25 millionths of a meter) The things that look like branches are called dendrites, and the one long, slender branch in the centre is called the axon. The cortical neuron is not the only kind. There are many different kinds of neurons: parametal neurons are the ones with triangular bodies at the bottom of the visual cortex picture. Information flows from the dendrites to the axon via the cell body (there are also some exceptions here) Dendrites surrounding a cell body, and then an axon. The inputs to the dendrites look like the following: When you get the epsps arriving, they are added together. Once they reach a certain threshold, then there is an output spike.
