Document Summary
Myelination occurs into the final stages of your 20"s. Brodman looked at the human brain and divided cortex up into different areas depending on the cell types or location. Central sulcus- deep into the brain. used to describe different parts of cortex. In front of this sulcus is the motor strip- plays a role in moving toes/fingers. Betz cells- biggest cell in the human cortex. Behind sulcus is sensory gyrus- all information comes in there. How developed your cortex is to determine how much something means to you. Lateral sulcus(fissure)- used to describe different parts of cortex. The brain is divided into general lobes: frontal lobe- occipital lobe (vision, parietal lobe- sensory cortex, temporal lobe- limbic system ( emotional regions , auditory cortex. Brodman found different types of cells as you go through the cortex. Top layer: layer 1- a lot of glial cells.
