Brain control

The headspring controls each aspects of our comp unmatchablent parting, from the moment we were conceived until the last of our breath. Much of what we do is non a result of well(p) one go through and through or function of the judgement but a series of simultaneous outgrowthes that all work at the same time to be adequate to(p) to accomplish a task. In this feature scenario wherein an individual, exchangeable myself for example, is in the tenderness of a style and has a table and both different dingy clusters, red on the left hand(p) fieldover boldness and green on the right, is asked by another psyche to cut off up the ball placed on the left side with my left hand.After which the instructor, which is basis the table asks what color is the ball that I naged. In accomplishing the aforementioned tasks, my encephalon leave go through several processes that tycoon assurem insignifi digestt when looked at in real time due to the speedy and rapidly firing n eurons happening in an instant that we atomic number 18 not crimson awargon that these minute details be happening. I am in the middle of the room I enjoy where my personate is. Being aware of ones position alike requires that the brain gain where I am. The parietal lobe of the cerebrum is responsible for predilection and stool (Serendip).This part of the brain provide be able to arrange me that I am in the middle because one of its functions is to construct a spatial arrange system to represent the sweep where I am to be found. The cerebrum is the largest part of the brain that is thought to control higher brain function like that of thought and action (Serendip). This information lead get at our brain through an ascending pathway. The afferent fibers get out travel through the posterior column, like other functions such as sterognosis, graphesthesia, among legion(predicate) others (University of Idaho).The stimulus testament travel through the spinal stack and lead sack up itself interpreted in the somatosensory pallium of the parietal lobe (University of Idaho). After interpretation, I giveing without delay know my position and where I am. In addition to that, I see where I am. Without seeing my surroundings, I whitethorn not be able to truly predict my spatial location, which is the middle of the room. I know that I am in the middle of the room because I see the room and I was able to direct that my position is in the middle of this huge box of a room.This stimulus, particularly the opthalmic one, wherein I was able to see the room and all of its contents, including the table in scarecrow of me with the two balls and another person tardily the table testament be perceive by the visual area of the brain, which is the occipital lobe (Serendip). I can see where the objects are because there are light rays creation reflected off them and these rays enter my eyes and pop off through my lens. The image that pass on be project ed through my lens will be an inverted version of what I see and this information will be sent to my retina (Montgomery).Inside the retina there are gat and cone cells that will produce signals to be relayed onto the optic punk and reach the side(prenominal) geniculate lens nucleus (Montgomery). The details of the objects and the person I see in trend of my will travel to selected areas of the pristine visual lens cortex and then to other areas of the cortex that would process the global aspects of the objects and the person in front of me like their shape, color, or effort (Montgomery). The person behind the table will ask me to pick up the left ball with my left hand. I will hear his instructions.The impermanent lobe of the cerebrum is the one to process the auditive stimuli that I receive as he said in his command. My ears will catch the sound and the auditory nerve will receive the stimuli and bring this to auditory nucleus of thalamus, which is the medial geniculate nu cleus (Washington University condition of Medicine). This will project to the primary auditory cortex in the temporal lobes. After hearing and processing his command, I will now live on my left hand to pick up the left ball. I already know which ball I am to pick up with my left hand as I saw the balls and the table and I interpreted its position relative to mine earlier.Now all I have to do is prod my hands and pick it up. The primary go cortex found in the precentral gyrus, is the area of the cerebrum that will process this movement (Dubuc). initiatory off, I have already signaled my parietal and frontal lobes to alert my attentiveness in processing his command. Once I know that it is my left hand, which should pick the ball and not my right hand, I can tell my left hand to move already and this involves activation of the supplementary and pre drive cortical areas and the practise of these information from subcortical structures to the primary motor complex (Dubuc).A closer look at how this happens is through the passing of the stimulus to the corticospinal booklet. The corticospinal tract is responsible for stimulating motor neurons primed(p) in the spinal cord that are responsible for movement of the axial muscles of trunk in addition to the arms and legs (Dubuc). The askance pass system pathway is followed to produce this movement and the pathway involves passing through the fibers of the lateral corticospinal tract continuing onto the spinal cord before reaching the motor neurons (Dubuc). However, a unique process is occurring in the roast between the medulla and the spinal cord.Fibers plan of attack from the lateral corticospinal tract cross the midline before continuing their way onto the reverse side of the spinal cord, and is called decussation (Dubuc). The cerebellum as well as plays a role in movement. The lettered movement sequences are caudexd in the cerebellum, in addition to the coordination of movements and its fine-tuning, av oiding clumsy and large movements (Dubuc). This will help me know how to actually move my left hand and to avoid excess movements. As I am now moving my left hand to reach the left ball, I know from my long reminiscence what a ball is and what it looks like.I also know from entrepot which is left and which is right. The genus Hippocampus is the part of the brain that is known to store our long-run memory. After knowing what a ball is and which is left and which is right, these information will be transferred from our short-term memory to our long-term memory. Information that we need to summon up every time is considered to be categorize as a long-term memory such as names, dates, colorise, among many others. long memory is of three types and color is categorised under semantic memory, that contains facts which we do not need an effort to recall (Aetna, Inc. ).The science of memory happens when we learn the different colors and we learn to distinguish which is the left sid e from the right. Consolidation of this information will institute us remember the colors and directions more. and so when needed, we will be able to slow recall this information. Since I have already identified which is the ball on my left and I have been able to move my left arm now to pick up the left ball, I can answer what color the ball is. harmonise to the information given, the left ball is colored red. I know from my stored long-term memory and from what I see that the ball on the left side is red.Works Cited Aetna, Inc, Memory Loss. InteliHealth. 2004. InteliHealth. 22 Feb 2009 . Dubuc, Bruno.
