Name the (3) different organizations of the cerebral cortex: superficial grey matter (neurons), white matter tracts (axons), deep nuclei (neurons): formed around ventricles; lateral to thalamus. Primary motor cortex: neurons that allow you to voluntarily move your muscles. Primary sensory cortex: receiving information from your skin. Where is it located: superficial grey matter is located in the cortex, organized into columns at the cellular level. Describe the (2) areas that are associated with speech. Broca"s area: located in the frontal lobe and is responsible for motor movement, of the tongue and mouth, to produce speech. Wernicke"s area: located in the temporal lobe, the understanding of speech.
