Document Summary

Temporal: lower part is involved in what stream objects are coded, auditory system, 3. The lateral sulcus or sylvain fissure = a deep groove: causes the temporal lobe to come outs like a wing sticking out of the brain. Central sulcus separates the partial from the frontal lobe. Somatosensory touch: the whole body is laid out here. Information first comes into v1, but it also comes into the primary areas of the other senses as well. In the rat, primary sensory and motor areas occupy nearly all the cortex. Premotor areas send commands to the motor areas: the prefrontal and parietal-temporal-occipital association areas (figure 5. 1d, these make up over half of the cortex. It is where: different modalities combine, hearing, touch, vision, planning occurs and decisions are made, b) attention is shifted, d) things are remembered. In humans, these association areas occupy 80% of the cortex.
