Animal behavior is patterned neuronal activity

In animals that have a nervous system, all motor, mental and visceral actions (and therefore behavior) are the product of neuronal activity. When neuronal activity in the relevant structures or pathways is disrupted or impeded – for example, with anesthetics -, that behavior stops. But this does not yet explain what is it about neuronal activity that…...

First Principles: Neuronal activity is contagious excitation, an electrochemical signal

“Activity” is a term that, in a neuron, usually describes the undoing of the voltage of their cell membrane. If such changes occurred in other cells, they would most likely soon be dead, intoxicated by high levels of calcium released from intracellular stores. In neurons, in contrast, either the undoing of the membrane potential is quickly reversed, or else it…...
