T1L21 anatomy of memory and emotion

Question 1

episodic memory:

• what
• __ into STM and ___ into LTM- __
• key area
• anatomy of consolidation
• parts of a memory
• modulation by emotion
• modulation by attention

Answer 1

• events, conversations, experiences
• encoding into STM, consolidation into LTM - recall

key area is hippocampus

consolidation:
hippocampus&raquo_space; fornix&raquo_space; mamillary bodies&raquo_space; ant thalamus

parts of a memory- neocortical sensory areas (as for perception, imagery); hippocampus links to neocortex via parahippocampal gyrus

modulation by emotion- amygdala
modulation by attention - ant cingulate gyrus

Question 2

semantic memory:
what
anatomy of linking together
anatomy of categorising
anatomy of retrieval
anatomy of parts of a concept

Answer 2

conceptual understanding, categorisation, knowledge, information

linking together parts of concept - anterior temporal cortex

categorising a visual perception- posterior inferior temporal cortex

controlling retrieval of sematic information- ventrolateral frontal cortex

parts of a concept - neocortical sensory areas

Question 3

emotion
what

contextualising

learning emotional relevance

preparing for response

visceral feelings

emotionally directed attention

emotional arousal

experience of reward

learning reward

Answer 3

• the experience of emotion or evaluation of affective relevance - the amygdala

regulating/contextualising - ventral frontal cortex

learning emotional relevance and recalling emotion- hippocampus

preparing for response - hypothalamus, autonomic ns

visceral feelings- anterior insula

emotionally directed attention- amygdala links to cortex and anterior cingulate gyrus

emotional arousal - aminergic nuclei

experience of reward - nucleus accumbens, amygdala

learning reward - ventral tegmental area
