The brain is divided into lobes. The parietal lobe is located at the back of the brain. It functions processing sensory information regarding the location of parts of the body as well as interpreting visual information and processing language and mathematics.
The Parietal is divided into two hemispheres
The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus.
One of the main functions of the parietal lobes is to receive and process sensory information from all over the body. The somatosensory cortex is found within the parietal lobes and is essential for processing touch sensations.
Therefore the above explains that the tactile signals displayed by the baby are received by the parietal lobes
