PSYCH 345 Lecture Notes - Lecture 3: Medulla Oblongata, Temporal Lobe, Corpus Callosum
Document Summary
Thalamus, hypothalamus, pineal gland: basal ganglia. A lot of inhibitory and excitatory areas in here so can contribute to diseases like huntingtons and parkinsons: limbic system. Involved a lot in ptsd and anxiety patients: midbrain, cerebral peduncles, corpora quadrigemina, superior colliculi (part of tectum) Receives projections from the retina: inferior colliculi (part of tectum) Receives projections from the ear: nuclei: controls heartbeat, physical functions, etc. Tegmentum: contains nuclei that control limb movements (red nuclei) and approaching desired objects (substantia nigra: hindbrain, cerebellum. Damage causes issues with equilibrium, posture, and skilled motor activity (gait ataxia: reticular formation. Damage causes permanent unconsciousness: pons and medulla oblongata. Bridge between higher functions: brainstem, hindbrain, midbrain, diencephalon, diencephalon, thalamus: sensory gateway, many nerve fibers from sensory systems synapse here, hypothalamus: Cerebral cortex: phylogenetically youngest structure (neocortex, humans have more cerebral cortex, mainly the frontal area, well developed in mammals, accounts for 90% of the human nervous system, has four lobes, occipital.
