Document Summary
Receptors: parts of the cell membrane that receive neurotransmitters that will prevent or initiate a current. Synaptic transmission or (electro-chemical action: two parts to elector-chemical actions: conduction and transmission. What makes neurotransmitters stop acting on neurons: 1. Reuptake: occurs when neurotransmitters are reabsorbed by the terminal buttons: 2. Enzyme decativation: speci c enzymes that break down speci c neurotransmitters: 3. Bind to autoreceptors: detect how much of a neurotransmitter has been released in the gap or the synapse and they send a signal to the neurons to stop releasing the neurotransmitter when an excess is present. Too much of one neurotransmitter or not enough to the other can e ect behavior, cognition, and mood. Brain is 3lbs: hindbrain : coordinated info coming in and out from the spinal cord. Contralateral control: each hemisphere controls the areas of the body opposite to the location of the location of the brain hemisphere.
