Discuss Various Biological Limitations Upon Clear Thinking

BIOLOGICAL LIMITATIONS TO CLEAR THINKINGMental health problems have been identified as a major component of global disease and befooling . These types of diss account for approximately 12 of check-adjusted life-years lost globally (Affi 2007 . The concept of clear cerebration is the main symptom that is run into in most psychiatric diss , such as Alzheimer s disease schizophrenic psychosis , Huntington s disease . Such disorganization of deception or behavior follows that main concept of Pia allow s theory of cognitive development , which is in the first cast based on the interrelations between repel sensory and genial development , which atomic number 18 experienced by means of and through a series of chronological make ups of preeminence starting from relationship to adulthood (Flavell , 1996 . Hence , the co gnitive office that is observed in standard individuals may also associate to consciousness or aw atomic number 18ness , which argon two ambiguous yet all- alpha(prenominal) terms in the field of cognitive neuroscience . Loss of cognitive ability is usually reflects imperfections or redress in the routine of the point , resulting in a disassociation from awargonness of consciousnessClear thinking is influenced by various biologic processes in the human carcass . Memory is a very important aspect in human thinking , and its loss or amnesia , is a usual neurologic dis observed later on a pathologic condition such as snapshot , anoxia or cephalitis . Patients with amnesia often suffer from a severe disability to remember things as well as loss their normal capabilities to think deeply . It has been determined that the proteins atomic number 20 calmodulase kinase II and adenylate cyclase are responsible for the normal learning and repositing . An opposite biological l imiting factor to learning and remembering ! is azotic oxide , which stimulates synaptic messages to the neuronal arranging for transmitting When nitrous oxide is deficient in amounts in the ace and blood system neural transmission is affected . The brains of stroke patients usually go through an oxygen-deficient stage that results in neural damage due to excessive fruit and release of excitatory neurotranmitters such as glutamate .

High levels of glutamate are deleterious to nerve cells because this paves the way for nitric oxide to bind with other molecules which in turn destroys the lipids and protein molecules in the brain One unfavourable effects is that th e deoxyribonucleic acid of brain cells are damaged and the DNA repair enzymes are unable to remodel the normal settings of the brain cells . And since DNA carries the information for the all the cellular processes , excessive ability is lost from the cell and the cell dies of deficiency in cellular storagesAnother biological limitation to clear thinking is the ability to concord attention and to process information . Deficiencies in these mental capabilities are observed in psychiatric cases of schizophrenia The inability to cover attention is caused by the failure to elucidate external hoo-ha or stimuli from what is presented to the patient for mental process . Such fragmentation of cognitive processes may be a result of the expiry of sensory gating , which is measured based on sound or touch answers . The simplest human startle response is the eyeblink response , which is mainly controlled by a gene rigid in...If you want to get a full essay, order it on our websit e: OrderCustom! Paper.com
