Chapter 3 the brain and the nervous system. In between neurons that are neither efferent nor afferent. All or none law: all action potentials have same strength and speed regardless of action potential. Neurotransmitters: agonist try to prolong effects of a neurotransmitter by blocking reuptake, mimicking effects of the nt or counteracting enzyme that cleans up the nt. Also may provide special ingredient needed to create more the of the nt: antagonist do the opposite, blocking receptor to prevent binding , speeding up reuptake and augmenting cleanup enzymes. Transcranial magnetic stimulation studies: turns on and off certain brain mechanism using strong magnetic impulses, only influences structures near the surface of the brain tho, is being used as therapy for clinical depression. Brain anatomy spatial precision can indicated when brain activity took place. Brain activity during task brain activity when not doing task = brain activity because of task: longitudinal fissure divides brain into left and right hemisphere.
