Digestion is a necessary part of the absorption process. Food first enters the stomach after you chew and swallow it. The stomach stores the food and liquid you swallow and mixes it with digestive juices that the stomach makes.
Processing primarily occurs in the primary somatosensory area in the parietal lobe of the cerebral cortex: information is sent from the receptors via sensory nerves, through tracts in the spinal cord and finally into the brain.he sensory information (touch, pain, temperature etc.,) is then conveyed to the central nervous system by afferent neurons. There are a number of different types of afferent neurons that vary in their size, structure and properties.
The cerebral cortex is responsible for higher brain functions like language and memory. The cerebral cortex is a layer of the brain responsible for complex functions. The cerebral cortex is the outermost layer of brain.View slideshow of images above.he cerebral cortex is responsible for higher brain functions like language and memory.
