Brain Might Contextual
The information we receive from the surrounding is analyzed in different areas in the brain. These areas are interconnected. Visual impulses reach the occipital lobe in the brain from where they are carried to the somatosensory are in the parietal lobe. The parietal lobe also receives sensory information from other areas of the brain. These stimuli are integrated and stored. The stored information is used to reason similar stimuli in the future. This creates a quicker response in recognition. This theory is consistent to the top down process created by Richard Gregory.
The brain is a complex body organ consisting of two cerebral hemispheres, two cerebellums and a brain stem. The brain stem is a continuation of the spinal cord. It consists of the mid brain, pons and medulla. The brain is made up of complex neurons that transmit impulses to other body organs. These impulses help other organs carry out their functions. Impulses are also transmitted to the brain after which a response is generated and sent back. Each part of the brain has specific functions that are inter-related to other parts of the brain. To understand where contextual image is processed, it becomes important to first review functions of different parts of the brain.
The cerebrum is the largest part of the brain. It consists of the frontal, parietal, temporal and occipital lobes. Each lobe carries out a specific function. The frontal lobe is associated with planning, reasoning, parts of speech, emotions and problem solving. The parietal lobe is responsible for movement, orientation, recognition and perception of stimuli. The occipital lobe is responsible for visual processing and the temporal lobe is responsible for recognition of auditory stimuli and its perception, memory and speech. (Serendip, 2005)
The cerebellum is located posteriorly and is sometimes called the little brain. This part of the brain is mainly responsible for balance. It receives information from the inner ear, sensory and optic nerves which help it to co-ordinate and develop a sense of position. Lesions of the cerebellum impair the brain's ability to analyze impulses from the eye and the ear, hence, a person with a cerebellar lesion loses the ability to precisely time and co-ordinate smooth movements. These patients also lose...
