the cerebral cortex
| Question | Answer |
|---|---|
| thalamus | receives sensory signals and sends signals to areas of forebrain |
| the only one of the senses that is not processed by the thalamus | smell |
| HYPOTHALAMUS* | regulates hunger&thirst, endocrine system, internal motivation (desire to eat food/water=growling) |
| reticular formation | draws arousal and attention especially in the higher parts of the brain. Is made up of a loose network of neurons. |
| limbic system | coordinates stress and itnegrates actions of the nervous system; regulates emotion, memory |
| cerebral cortex | divides the brain into 2 hemispheres and 4 lobes. Controls perceiving, thinking, speaking |
| Occipital Lobe | responsible for vision (Two i's) |
| Temporal Lobe | controls auditory input, speech, music, and balance |
| parietal lobe | a somato-sensory cortex that processes info about temperature, texture, pressure, and pain |
| frontal lobes | Controls abstract thought and emotions; MOTOR cortex (Phineas Gage) |
| pre-frontal cortex | planning, complex behavior, decision making |
| basil ganglia | controls part of motor system (parkinson's) |
| the central fissure divides what two areas of the brain? | the frontal and parietal lobe |
| motor cortex (location and function) | at the rear of frontal lobes; controls VOLUNTARY mvmts |
| somatosensory cortex (function and location) | at the front of parietal lobes; processes body touch and mvmt sensations. |
| association areas | areas of cerebral cortex NOT involved in sensory/motor functions, but involved in mental functions (learning, remembering, thinking) |
| Broca's area (function and location) | controls language expression (speech); located on the frontal lobe |
| Aphasia | Language problems (with spoken or written words) |
| apraxia | inability to organize mvmt (cannot move/uncontrolled) |
| alexia | inability to read (cannot decipher individual letters) |
| agnosia | inability to process sensory input (seeing) |
| brain plasticity | the brain's ability to change by improving after damage or building new pathways based on experience. |
| neurogenesis | the formation of new neurons |
