2. Parietal lobe: It is involved in motor control and understanding information regarding the skin senses like touch, pressure, temperature, and pain.
3. Occipital lobe: It controls our vision. It is a visual processing center. The information regarding the shape, colour, depth, and speed of the object is received and interpreted in the occipital lobe.
