PS101 Lecture Notes - Lecture 6: Phineas Gage, Frontal Lobe, Parietal Lobe
Document Summary
Substantia nigra: the nucleus from which dopamine neurons send their axons to the striatum (forebrain) Thalamus: serves as a relay station for incoming sensory information. Hypothalamus: important for motivation, basic drives, and control of the endocrine system. The limbic system: involved in the regulation of motivation, emotion, learning, and memory. Hippocampus: important for certain types of learning and memory. Striatum: produces fluid movements and helps with learning and memory that does not require conscious awareness. Nucleus accumbens: important for motivation, reward, and addiction. Frontal lobe: planning, impulse control, judgement, immediate memory, emotions, social understanding, motor skills. Parietal lobe: verbal memory, language, processing tactile sensory information. Temporal lobe: auditory processing, language skills, memory (hippocampus) Sensory cortex: registers sensory neurons, located in the parietal lobe. Motor cortex: registers the motor neurons, located in the frontal lobe. Association cortex: registers complex functions, including higher-order sensory processing, integrating information from different senses, thinking, planning, in the frontal lobe.
