| What are the components of the limbic system? | Limbic association cortex, hippocampal formation, amigdaloid complex, septal nuclei, basal ganglia, thalamus, hypothalamus, epithalmus, portions of the periaqueductal gray and the reticular formation. | |
| What are the components of the limbic association cortex? | Orbito-frontal, cingulated, entorhinal, and temporal pole (parahippocampal gyrus and uncus). | |
| Where is the hippocampal formation? | The temporal lobe. | |
| What does hippocampal formation include? | Hippocampus (Ammon’s horn), subiculum, and dentate nucleus. | |
| What is the purpose of the hippocampus (Ammon’s horn)? | It converts info to memory. | |
| What is the purpose of the subiculum? | It connects the parahippocampal gyrus to the hippocampus, receives sensory info. | |
| What is the purpose of the dentate nucleus? | Projects information out of the cortex. | |
| What are the complex of nuclei in the amigdaloid complex? | Cortical medial, basolateral, and central nucleus. | |
| What is the purpose of the corticomedial nucleus? | Olfaction. | |
| What is the purpose of the basolateral nucleus? | All other emotions. | |
| What is the purpose of the central nucleus? | To project an information out. | |
| What are the subnuclei in the septal nuclei? | Medial, lateral, and dorsal subnuclei. | |
| What is the purpose of the medial, lateral, and dorsal subnuclei? | Emotions behind eating. | |
| What are the components of the basal ganglia? | Ventral striatum, ventral pallidum, and nucleus accumbens. | |
| What are the components of the thalamus? | Anterior nuclei, dorsomedial nucleus. | |
| What is the purpose of the hypothalamus? | It provides the major output pathway of the limbic system. | |
| What are the components of the hypothalamus? | Mammillary nuclei, ventromedial nucleus, lateral hypothalamic area. | |
| What are the components of the epithalmus? | The habenula. | |
| What is the purpose of the habenula? | To store smell memories. | |
| What are the functions of the limbic system? | MMOVE: motivation, memory, olfaction, visceral responses, and emotions. | |
| What is the role of the hippocampus and memory? | To convert short term memory into long term memory. | |
| What is the role of the amygdala? | Autonomic and the orienting responses, emotion, food intake, arousal, and sexual activity. | |
| What is the role of the septal area? | Emotions, learning, autonomic responses, drinking, feeding, and sexual activity. |
