Functions
| Question | Answer |
|---|---|
| Pons and medulla | waking, sleeping, and locomotion |
| Cerebellum | learned skilled movements (think throwing a dart) |
| reticular formation | maintaining general arousal |
| tectum | superior colluculi: receives sensory input from eye inferior colliculi: receives sensory input from ear |
| red nucleus | limb movement |
| periacquecutal gray | species-typical behavior |
| substantia nigra | produces dopamin -- reward-bahaviour and movement initiation |
| hypothalamus | interacts with pituitary gland involved in motivated behaviour |
| What two parts make up the epithalamus? | Pineal Gland and the Habenula |
| thalamus | relay station -collection of nuclei which receive sensory motor inputs -functions to integrate different inputs and project them to various cortical areas |
| lateral geniculate body | receives visual input and routes it to occipital cortex |
| medial geniculate body | receives auditory input and routes it to temporal lobe |
| ventrolateral posterior nucleus | receives somatosensory input and routes it to parietal cortex |
| ventral anterior nucleus | receives motor input from basal ganglia and routes it to frontal (motor) cortex |
| Basal Ganglia | functions controlling and coordinating movement patterns |
| What makes up the limbic system. | hippocampus, amygdala, septum, cingulate gyrus |
| hippocampus | functions in learning and memory |
| amygdala | functions in emotion and behaviour |
| septum | functions in emotional behaviour |
| Primary areas | project to spinal motor systems or receive sensory input (via thalamus) |
| secondary areas | adjacent to primary areas Sensory: primary - secondary Motor: secondary - primary |
| tertiary areas | associated with cortex, located between secondary areas, not specific to sensory to motor information, perform complex functions |
| fasciculi | long tracts that connect one lobe to another |
| what fascicles connects Brocca's area to Wernicke's area? | Arcuate Fisciculus |
| arcuate fibers | short connections between adjacent gyri |
| mamililiary bodies | recollective behaviour (sometimes called part of the thalamus) |
| Pineal Gland | Circadian Rhythm |
| Habenula | hunger and thirst |
