Document Summary
Memory impairment from marijuana use occurs because the thc alters how information is processed in the hippocampus, a brain area responsible for memory formation. Tying human behaviour with neurons is dif cult. Synapses between terminal buttons of the axon of a motor neuron and a muscle. Simplest neural circuit = our re exes: brain > spinal cord > the interneuron excited motor neuron, causing muscular contraction > the muscle causes withdrawal from source of pain > axon of sensory neuron (pain) Central (brain and spinal cord) verse peripheral nervous system (sensory neurons that spread out and motor neurons to move muscles// nerves that lead to muscles and organs) Autonomic (controls self-regulated action of internal organs and glands. 3 kinds of neurons connect cns to body. Afferent nerve carries info from sensory receptors in to to the brain. Efferent nerve carries info from the brain to the herons. In mammals, little more than a relay station.
