Document Summary
Life and energy: a general rule of nature is that if you separate things, or move them out of equilibrium, they will tend to re-equilibrate. It doesn"t really matter what type of force is involved. If a stimulus causes this potential to rise (move toward 0), this is called a depolarization. If a stimulus causes this potential to fall (become more negative, move further from 0), this is called a hyperpolarization. If membrane is depolarized to -60mv, it will just return to -70mv: similarly, if membrane is hyperpolarized to -80mv, it will also find its way back to -70mv. +30mv: action potential causes membrane to go to +30 and then down past , the action potential: the players. Myelinated axons have a faster rate of conduction. Inhibitory: neurotransmitters such as gaba and glycine are classified as inhibitory because their receptors allow the influx of anions (negative ions like cl-)
