BMS11004 - WEEK 5 WEDNESDAY Flashcards
cerebral cortex, cerebellum, hippocampus, basal ganglia, amygdala, neocortex, thalamus
state the 3 types of cortex
neocortex (dark pink)= ‘new’, expanded to be bigger in human
hippocampus
olfactory cortex
how is neocortex divided up by lateral, central, parieto-occipital sulcus
lateral sulcus divides temporal from frontal and parietal lobe
central sulcus divides frontal and parietal lobe (the only sulcus running from superior down to lateral sulcus)
parieto-occipital sulcus divide parietal and occipital lobe
how deep is neocortex, how many layers
6mm and 6 layers
what is pia mater (neocortex)
very thin and cling to outside of brain to keep edge of brain separate from CSF
what does Wiegert-PAL show
stain myelin, showing myelinated axon
what are gyri
bumps on outside, ridges between fissures and sulci
what are sulci
the inside grooves, small fissure
what is Brodmanns cytoarchitectural map
show cortical map of layers, and differences in size or density. each cortical area has number, with model suggesting cortical areas that look different are also different function
how can you map the neocortex
Brodmanns cytoarchitectural map
lesions/direct stimulation
noninvasive (PET, fMRI, EEG)
where is limbic lobe, and contains what
medial aspect of temporal lobe, with hippocampus, cingulate gyrus
process emotions, motivation
what is insula cortex (in hidden area of the neocortex)
function ranges sensorimotor processings to emotive regulations
give functions of basal ganglia
initiates movement, communicate with primary and association motor cortex
impairment cause Parkinson
what does amygdala do
control fears, anxiety
what is function of the hippocampus
memory
what are oldest part of cortex
hippocampus
olfactory cortex
