cerebral lobes and divisions:
fissures are deeper than sulcuses (s for shallow)
dividing frontal and temporal lobes = lateral fissure = runs horizontal,
temporal lobe below
temporal lobe = 3 gyri - top is superior temporal gyrus
transverse temporal gyrus (of heschl) is the most superior gyrus of the
temporal lobe running inside the lateral fissure
^ STG and TTG are auditory
planum temporale = posterior part of inside of lateral fissure (technically
parietal lobe?) = interpretation of words
Neuroanatomy practicals 1
, dividing frontal and parietal lobes = central sulcus = about halfway across
cerebrum where sulci go from running longitudinally to perpendicularly, runs
all the way from medial to lateral fissure
frontal lobe anterior to motor cortex = prefrontal cortex
anterior to central sulcus = motor cortex
posterior to central sulcus = sensory cortex
mapping from lateral to medial part of gyri: face > hand > upper limb >
head neck trunk > upper legs/pelvis (down into longitudinal fissure) >
lower leg > foot > genitals
central sulcus also forms paracentral lobule (u shape) in half brain
Neuroanatomy practicals 2
, dividing parietal and occipital lobes = parieto-occipital fissure = deep fissure
running perpendicular in sagittal brain
parietal lobe divided into superior and inferior lobules
dividing cerebellum and cortex = transverse/horizontal fissure
dividing hemispheres = longitudinal fissure = contains superior sagittal sinus
and lies overtop falx cerebri
dominant hemisphere is the one with language centres (usually left):
brocas = left inferior part of frontal lobe (motor) - expressive
wernickes = near planum temporale in left temporal - receptive
Neuroanatomy practicals 3
, corpus callosum = white matter curve above lateral ventricles, connects L/R
hemispheres
cingulate gyrus = above corpus callosum in sagittal brain (contains cingulum -
inputs from all cortex) > cingulate sulcus above that
diencephalon = thalamus, hypothalamus, epithalamus, subthalamus
thalamus/hypothalamus make walls of third ventricle, groove between is
hypothalamic sulcus
pineal gland = part of epithalamus, secretion of melatonin for circadian
rhythms, found posterior to thalamus
