Document Summary

Psyc100- introduction to psychology- lecture 4- behavioral neuroscience. Synapse clearing rapid cleaning needed before transmission additional signals, largely dependent on the neuron-transmitters involved. Agonist: promote or enhance operation of neurotransmitter. Antagonist: oppose or inhibit the operation of neurotransmitter. Neuromodulators: chemicals that may have a widespread or general effect on the release of neurotransmitters. Endocrine system: system of glands that produce and secrete chemicals called hormones. Hormones: chemicals produced from the endocrine system into the blood stream. Limbic system: group of structures involved in the control and direction of emotional behavior. Amygdala: emotional reactivity, aggression and processing od odors. Hippocampus: emotional reactivity and storage of memories. Forebrain: corpus callosum- allows the forebrains two hemisphere to communicate. Sometimes cut to prevent intense seizures/sever epilepsy: cerebral cortex (cerebrum)- handles sensory processing, motor controls, memory formation and storage, thalamus integrates incoming information and relays it to the cerebral cortex.
