Process of the cell that collects and receives info/impulses from other cells and transmits impulses toward the cell body by way of electrical disturbances.

Dendrites are typically short and highly branched.

26
Q

What is ‘chaos’?

A

Electrical energy or billions of impulses.

27
Q

Dendritic spines

A
