central sulcus seperates what
frontal lobe from parietal lobe
parieto-occipital sulcus seperates what
occipital from parietal
pre-occipital notch seperates what
occipital lobe from temporal lobe
lateral fissure separates what
the frontal and parietal lobes from temporal
Long association fibers are called
bundles
Commissural fibers
Connections that occur between the same area on both hemispheres.
Corpus collosum Runs through
all lobes and connects frontal, parietal, temporal, and occipital lobes
Anterior commissure:
temporal lobes
Brodmann numbers
a map of the cc that helps to locate functional area
Brodmann numbers 1,2,3
Primary somatosensory cortex (sensation)
Broadmann number 4
Primary motor cortex
Broadmann number 44 and 45
Broca’s area expressive aphasia if damaged
Broadmann number 22
Wernickes area receptive aphasia if damaged
The premotor cortex helps
plan voluntary movement before it happens
If the premotor cortex is damaged A person may have trouble with
motor planning
The supplemental motor area helps
plan and initiate coordinated movement patterns
Internally generated, meaning
the person decides to move without an outside cue
The frontal eye field controls
voluntary eye movements
Broca’s motor speech area is the part of what lobe
frontal
Broca’s motor speech area is the part of the frontal lobe that helps
turn thoughts into spoken words.
What does Primary Somatosensory area (S1) detect
touch, pain, temperature, pressure, vibration, proprioception
Secondary somatosensory cortex, is a sensory processing area that helps the brain do what
interpret and make meaning of touch information
Left brain is generally
Understanding and production of language, intellect, analytical thinking, logical, Controlled, mathematical, rational, positive emotions
Right brain is generally
Nonverbal processing, artistic ability, sensory, emotion, nonverbal thinking, hand eye coordination, body image awareness, expression of negative emotions
