This episode explains how your nerve cells, called neurons, make connections called synapses with other neurons to transmit information from one neuron to the next, through changes in the electrical potentials between the inside and outside of neural membranes. It is important basic information that you’ll need to understand how your brain works, but it isn’t specific to Nexus Theory, so if you’re a scientist or someone already familiar with these structures and functions, you can safely skip to Episode 6.
