|
Term
| how does the hypothalamus exert control on emotions and internal homeostasis? |

|
Term
|
Definition
| cortex surrounding hippocampus that serves to help store memory |

|
Definition
| associated with memory retrieval and recognition of scenes |
|
|
Term
| function of the entorhinal cortex? |
|
Definition
| pathway in and out of hippocampal formation, associated with spatial memory. Part of the parahippocampal gyrus |
|
|
Term

|
Definition
complex analysis
planning

|
Term
| function of Dorsolateral Prefrontal Cortex? |
|
Definition
| working memory, executive function, integrates many areas |
|
|
Term
| function of anterior/inferior temporal cortex? |
|
Definition
| verbral memory (L), spatial memory (R) |

|
|
Term
| stimulation of caudal VL periacqueductal gray provokes? |
|
Definition
| immobile, relaxed posturing |
|
|
Term
|
Definition
associated with dopamine projections and reward system
leads to increased likelihood of conditioned motor reponse and repeating rewarded behaviors |
