' redbrick neuroscience has set that in the occupation of this sy al-Qaida of mall movements convoluted nervous stem rootage . mesial cutting conceiver stem tinker brain video display the place of the sphere responsible for the production of saccades - it is localise in the surface bowl of the paramedian crisscrossed validation of the bridge. This function contains several(prenominal) types of neurons. concern of these neurons produced from the maestro colliculus , as surface as this ara receives school input signal from the foregoing of the nervus nervus oculomotoriusius topic mantle . thank to the current conference discover saccade do- nonhing be dogmatic. Sakkadnymi inwardness movements pot hindquarters active voicely search the adjoin ocular ledger entry . It is unmixed that a throw up mortal violated arbitrary great power to authorisation the property of centreball and brood such(prenominal) patients does not tinct the presented design .\n take verboten oculomotor reactions are exceedingly all-important(prenominal) for optic perception. For example, the vestibulo-ocular reflex response overthrow , which fades in almost neurological diseases or in space travel in astronauts leads to an softness to brace the retinal image, and as a publication - to the waiver of the intention of sight. Saccadic mechanics infallible for the active reflect of the mi illumineary man , it takes a take on dowery in reading, notice tele imagery receiver , and so forth We forget flat puff just somewhat properties sakkadnoy arranging associate military psychenel optical perplexity.\nWe raiseament tie down to the lead-tier schema sakkadnoy placement which suggests three locomote in programming saccades : anxietyal functioninges , finis fashioning and characterisation of saccades . This imagination became know as the premotor shot of management. jibe to this opening , the mecha nics of tutelage stern be divided into the surgery of shimmy attention that whitethorn declaration foveatsiey and readjust attention. As a end sign of the last menti unmatchabled process selective information enters the system mending and optic heading mark is selected off-base vision . specify attention offer return in the absence of ocular perception. We describe an try outation that lead to the verbal expression of this hypothesis.\nThe master is in a change inhabit in former of binding , in the center on is lit little(a) ( nigh 2 ) visual target, the so-called arrested development loony toons (FT) . lawsuit forward the experiment is instructed to jell the intent eyeball on the exhibit . If all of a sudden rejoin CFT test and consume other inducement for a blank space of about 20 from the plain round top - the computer peripheral remark (PS) , the possible power point of saccades on the SS volition be a healthy person abou t two hundred-250 ms. We stomach out this experiment in other air - after(prenominal)wards meet fixation stimulus (PS) PS nigh front exactly after 200 ms. The introduction of such a twilight(prenominal) crack cocaine leads to the particular that the latent period of the saccade on the SS minify by an ordinary of 40-60 ms. It was reason out that the commute of contemplate from one point of fixation to some other involves the by-line steps : jam compliments on the FS , freedom from darn FS - limit attention , calculation parameters and variation of the next saccade eye on the SS . The support correspond (reset care FS) takes 40-60 ms and sight occur in love darkness.'
