... • The brain is made up of neurons and glial cells. Neurons are communication cells that receive, process, and pass on neural signals. Glia support and insulate neurons. • Neuron signaling is an all-or-nothing event. When the number of positive inputs exceeds a certain threshold, the neuron fires an ...
