Cerebral Cortex/Lobes
Vocabulary | Definition |
---|---|
gyrus/gyri | folds or wrinkles of the cerebral cortex |
sulcus | shallow groove between gyri |
fissure | deep groove between gyri or parts of the brain |
longitudinal fissure | separates the cerebrum into right and left hemispheres |
transverse fissure | separates the cerebrum from the cerebellum |
central sulcus | separates the frontal lobes from the parietal lobes |
lateral fissure | separates the temporal lobes from the rest of the cerebrum |
primary motor cortex | responsible for voluntary skeletal muscle movement, found in the frontal lobes |
premotor cortex | retains the memory of your skeletal muscle movements (like playing a sport or instrument), found in the frontal lobes |
precentral gyrus | home of the primary motor cortex, gyrus in front of the central sulcus |
postcentral gyrus | home of the primary somatosensory cortex, a gyrus behind the central sulcus |
prefrontal cortex | area of thought, reasoning, judgment, decision-making; found in the frontal lobes |
Broca's area | a motor area that allows you to form words (to speak), found in one of the frontal lobes - usually the left |
primary somatosensory cortex | area that collects all sensory information from the skin, allows spatial discrimination; found in the parietal lobes |
somatosensory association cortex | allows you to identify objects by touch alone, found in the parietal lobes |
gustatory cortex | allows for your sense of taste, found in the frontal lobes |
primary auditory cortex | receives impulses from your ears to allow you to hear, found in the temporal lobes |
auditory association cortex | allows you to recognize what you hear, found in the temporal lobes |
olfactory cortex | allows you to smell and tell the difference between odors, found in the temporal lobes |
Wernicke's area | allows you to understand language (either heard or read), found in the temporal lboes |
primary visual cortex | receives impulses from your eyes and allows you to see, found in the occipital lobes |
visual association area | allows you to recognize what you see, found in the occipital lobes |
tract | group of axons in the central nervous system |
pyramidal cells | large neurons found in the primary motor cortex |
