BIOL 430 Lecture Notes - Lecture 32: Medulla Oblongata, Basal Ganglia, Olfactory Nerve
Document Summary
No brain stem (oldest part of brain) Embryonic development 6 major brain regions. Most developed in humans, olfactory nerve, optic nerves (chiasm), corpus callosum. Continuation of the spinal cord and consists of the medulla oblongata, pons, and midbrain. Gives rise to the thalamaus & hypothalamus. Newest (evolutionarily) and largest part of the brain as a whole. It is in the cerebral cortex that perception, thought, imagination, judgment, and decision making occur. Higher cortical functions: morals, decisions, math, ethics. Brain lateralization connects the two cerebral hemisphere. Flash word only on right side of screen. Passing word through left side of brain. Flash word only on left side of screen. Each lobe associated with a different function. 4 major divisions frontal, parietal, occipital and temporal. Frontal reasoning, planning, parts of speech, movement, problem solving, ethics, judgement. Parietal movement, orientation, recognition, perception of sensory stimuli. Occipital visual processing temporal lobe associated with perception and recognition of auditory stimuli, memory, and speech.
