Limbic System Flashcards
Main relay station in the olfactory pathways
Olfactory bulb
connection of olfactory cortex to what part of thalamus provide anatomic basis for a role in olfaction in emotional behavior
Dorsomedial;
Most vulnerable part of the hippocampus
CA1 (Sommer sector)
Type of memory that refers to conscious retrieval of information
Explicit memory
Type of explicit memory that refers to personally experienced facts and events with special spatial adn temporal localization
Episodic (unique) memory
Type of memory that refers to the memory of culturally and eudcationally acquired encyclopedic knowledge
Semantic memory
Refers to the memory that suports the learning and retention of skills
Implicit memory
Refers to the phenomenon in which repeated performance of a motor act, such as driving or riding a bike, enhances and automates future skill for the same act
Procedural Memory
refers to short- lived enhancement of perceptually based performance following a recent exposure to visually similar material
Priming
Anatomic Corelates
Episodic Memory
Mesial temporal cortex
Others:
- cortico-cortical connections from posterior and anterior neocortices to the entorhinal cortex
- hippocampus- mamillary body0 anterior and medial thalamic nuclei via fornix and MT tract
- basal forebrain cholinergic nuclei
Anatomic Correlates:
Semantic Memory
temporal, parietal, occipital lobes, particularly temporoal neocortex
Anatomic Correlates:
Short- term memory
L Prefrontal cortex- verbal material
R PFC- nonverbal material
Anatomic Correlates:
Procedural Memory
subcortical circutis- basal ganglia, cerebellum
Anatomic Correlates:

not certain
Most common type of amnesia
Anterograde
