5 0. Question 7 Action Potentials are the neurons output. Action potentials also known as spikes. These spikes are: Important energy source for the cells Binary (digital) representation of the neuronal information; each spike is either "all" ("") or "none" ("0") Although very important, we find them in very few nerve cells Analog representation of the neuronal information larger spikes are capable to transmit more information. Total / Question 8 Optogenetics is a new scientific method allowing: Coloring of different cell types with different colors Activation (or inactivation) of specific cells (that were /9
