parahippocampal cortex - functions
- encoding and recognition of scenes
- face recognition
- understanding social context of situations
connection between hippocampus and parahippocampal gyrus
subiculum
most primitive part of the cortex
hippocampus
how many layers does the hippocampus have
3
hippocampus - function
- short term memory
- spatial navigation
- control of attention
amygdala - function
memory of emotional reactions
cingulum - define
white matter within the connection between the cingulate cortex and the parahippocampal gyrus
cingulum - function
connects frontal and parietal lobes with the parahippocampal and adjacent temporal cortical regions
connection between amygdala and thalamus
stria terminalis
stria terminalis is associated with what functions?
anxiety, gender identity
white matter connecting the hippocampus to certain midline structures
fornix
where does the fornix originate
fimbria of hippocampus
where does the fornix terminate
septal nuclei and nuclei accumbens
connects amygdala to various parts (e.g. hypothalamus, thalamus, brainstem, septal nuclei, nuclei accumbens)
