Biological Bases of Behavior
Term | Definition |
---|---|
Frontal Lobe | -Behind the forehead, last to fully develop, and is connected to speaking, judgement, decision making, and impulse control -Contains broca's area on the left side: expressive speech |
Parietal lobe | -Top of the head, contains Somatosensory cortex and motor cortex -Functions: Spatial organization, sensory information |
Somatosensory cortex | Receives information from sense organs |
Motor cortex | Sends commands back to the body |
Temporal lobe | -Near your ears (Auditory processing, Auditory cortex) |
Auditory processing | Left lobe contains Wernicke’s Area: receptive speech |
Auditory Cortex | Receives information from OPPOSITE ear |
Broca’s & Wernicke’s Aphasia | the loss of ability to understand or perform speech |
Occipital Lobe | -Back of your head, and Contains visual cortex Receives information from opposite visual field of each eye |
Cerebellum | -“Little Brain” Functions: Balance, motor function & memory |
Two Hemispheres | Connected by the corpus callosum The brain is cross-wired to the body |
Left hemisphere | Language, analytical thinking, control of right side of body |
Right hemisphere | Spatial reasoning, control of left side of body |
Split Brain & Hemispherectomy | Brain hemispheres can be separated to stop seizure activity -Sever corpus callosum -Remove one half of the brain |
Plasticity | Ability of the brain to find new pathways around damaged areas |
Neurogenesis | Production of new neurons |
Split Brain & Hemispherectomy con’t | -Split brain studies: Michael Gazzaniga -Left brain reads; right brain interprets |
