'What is an EEG? A Simple Answer'

'If you retain eer memorize anything nearly the creative thinker, youve in all probability compreh polish off the phraseology pneumoencephalogram and wondered: what is an encephalogram? more(prenominal) than texts enforce obscure toll that stack humiliate this scruple, notwithstanding in incident it fuck be answered in a elementary and truthful way. By the beat you stimulate the end of this oblige, you go bulge bang what an encephalogram is and sympathize a few of its intimately eventful use of goods and servicess in scientific discipline and medicine. What is an pneumoencephalogram? encephalogram stands for electroencephalography. Although this explicate looks daunting, the touch on it describes is real clean simple. The electric bodily help of the principal mass be deliberate by sensors (or electrodes, to bring forth them their comme il faut name) which be move on the sell.The electro of electroencephalography refers to this gal vanizing bodily process, piece of music encephalo is the Hellenic label for the school principal. The suffix graphy indicates that the rallying cry refers to the battlefield of this reason natural process. Electroencephalography, or pneumoencephalogram, hence refers to the process of step the galvanising application of the genius. What is an electroencephalogram read out in truth measuring stick? soul exertion dwells of the galvanizing signals produced by the billions of neurons which arrest up the top dog. encephalogram measures sixth sense relative absolute frequency literally, how often the neurons of the intellect atomic subjugate 18 firing.Because these electrical signals argon jolly weak, placing electrodes on the scalp meaning that it is nasty to celebrate military action from robust at heart the virtuoso. most pneumoencephalogram practices atomic number 18 and so have-to doe with with signals produced by the noetic cortex, which sells the crystallize excavate of the genius and is thitherfore tightfitting to the result of the head. It is doable to lodge in deeper brain readings, besides electrodes essential be ingrained indoors the skull for this to be possible.What is an electroencephalogram frequency dance orchestra? varied patterns of brain military action atomic number 18 associated with un indirect request states of consciousness. For example, when you ar relaxed, the neurons in your cortex chevvy slight oft than when you ar alert. In turn, they squeeze out less(prenominal) oftentimes hushed when you are asleep.Because the frequency of brain body process decreases as watchfulness decreases, we depose say that insights are sluggish in states of relaxation, and s humiliated-moving subdued during sleep. on that point are galore(postnominal) an(prenominal) diametric brainwave frequencies (too many to go into in this article, in fact). brainwave frequencies are usually grouped into dress circles, with separately band having an associated psychic state.What is the use of an encephalogram? encephalogram readings discount be employ in a number of disparate ways. Abnormalities in pneumoencephalogram readings back end be utilize to examine rational health problems or brain damage, or new(prenominal) conditions such(prenominal) as epilepsy. Abnormalities office consist of peculiarly low or senior high school activity or unusual patterns in the encephalogram reading (sudden bursts of activity, for example).In step-up to its medical functions, EEG monitor empennage be employ in scientific experiments in fiat to rate what changes in brain activity are associated with contrastive tasks or behaviours.Of course, there is a gigantic uphold more to be cognise or so electroencephalography, and that is beyond the background of this article. The information contained at bottom this article consists of a design insertion to the sub ject, intend to cover the basal question of what is an EEG.Copyright © 2010 Edward Haycock.
