The Sophistication of the Brain Essay -- Neurology

To what extent is it true that the brain is a sophisticated information processor?The human brain is the almost important part of the nervous system. The brain along with the spinal cord makes up the central nervous system and together they control all of the luggage compartments important functions, such as labor functions, speech, vision, hearing and also involuntary functions like breathing. Many of these functions are localised to a specific field of battle of the cerebrum. The cerebrum is split into four lobes the frontal, parietal, temporal and occipital lobes, which are specialised to carry out their different roles. The cortex is divided into two hemispheres the left hemisphere is associated with motor control, speech and language functions and logic whereas the right hemisphere is linked to spatial perception and creativity.Communication in the brain occurs via neurons which transmit galvanizing impulses to other neurons by neural conduction (Wickens, 2009). They are co nnected by synapses which are small gaps between two nerve cells. There are approximately one billion neurons in the brain (Wickens, 2009), meaning that there are even more synapses. Synapses allow electrical impulses to be passed from neurone to neurone as chemical messages in the form of neurotransmitters, since electrical messages cannot cross the synapse.Cognitivism was developed in the 1960s to help explain what behaviourism and the biological perspective could not. It aims to find out how conscious thought processes can excise behaviours. The theory likens the processes of the mind to the way in which a computer processes information. The modularity of the mind theory was mentioned by Jerry Fodor in his 1983 book Modularity of Mind. He suggests that the mind is compos... ...splayed on the screen. However, the brain is not as fast as a computer when completing tasks that involve calculations or retrieving information from the stores. Nevertheless it is capable of understandi ng emotions and storing entropy by the depth of processing. It can encode semantically which does not require rehearsal and allows memories to be retrieved easily without cues.Works CitedBaddeley, A. (2000).
