PSYCH 10 Lecture Notes - Lecture 4: Temporal Lobe, Auditory Cortex, Neurogenesis
Document Summary
Lecture 4: tools of discovery and older brain structures. Scientists can selectively destroy tissue (excising or removing a portion of brain tissue: or electrically, chemically, or magnetically stimulate the brain, eeg (electroencephalogram) Our brains have evolved over time: brains adapt continually to new stimuli, less complex brain in primitive vertebrates. Handle basic survival functions: more complex brain in advanced mammals contain new brain systems built on the old. The brain stem and thalamus: without the brainstem, the brain wouldn"t work, composed of medulla, pons, reticular formation, thalamus, thalamus is the coordinator of the sensory input. Takes in motor information from the brain and sends it back through the spinal cord: the farther down the brainstem, the more essential the function. The right side of brain controls movements on left side of body. Right side paralysis = left side of brain damage: the oldest and innermost brain region. Medulla: located at base of the brainstem, controls heartbeat and breathing.
