Proof that "blind sight (blind site)" which is supposed to be unconscious but appears unconsciously happens in daily life

ByHorrigans

BlindnessWhat is "blindsight · blind site" is that, regardless of whether there is no visual acuity due to damage of the brain related to vision, or it is in a state that it is not perceptually visible, "Where is it because it is incorrect "When you are told" When you say "at a significant level above the chance level" it is said that it was proved to happen in daily life even if it is not under special conditions.

"I can not see it unconsciously" Evidence of blindness in daily life scenes - Even without being conscious of "visible" by visual impairment due to cerebrovascular disorder "movement" "brightness" "color" Look to the prominent part - / National Institute of Physiological Sciences

It is an image of blind view that this seems to be unable to be conscious when it is visible. Despite being unaware that the person himself is visible, some visual functions such as eye movements can be recovered from damage.


Normally, information seen in the "retina" of the eye is sent to "visual cortex" via "thalamus", and it is conscious as the first time "seeing" here, but this is the research team of Isa et al. From the results of the research, it is understood that information is unconsciously transmitted to the brain via the "upper hill" of the midbrain when the "visual cortex" is impaired due to cerebral infarction, etc. Thing.


This is an image image of "how to see" of a monkey in blindness. Even a monkey blinded by visual impairment can capture the characteristics of image information such as "movement", "brightness", "color" from the visual information, and can turn his eyes, that is, "I can not see it unconsciously That's it.


In this time, the research team examined whether the blindness phenomenon occurs in the scene of daily life, not the special visual stimulation condition of the laboratory, using the image of the daily life scene, and the visual field which should not be seen He said that he can turn his eyes on the part that is prominent in "movement" "brightness" "color". In other words, just by looking at the movements of the eyes, it seems to be able to see where you are attentive to unconsciously, although you can not see it.


According to Yoshida Assistant Professor, "In a visually-impaired patient due to cerebrovascular disorder (such as semi-blind after the cerebral infarction), the possibility that blindness can be used in everyday life has been clarified, and visually impaired patients can also visually It can be said that it showed the significance and possibility of function recovery.In addition, it is possible to inspect to what extent (unconscious) can be seen by the inspection method "Measurement of eye movements while watching a movie clip" I understand. "The possibility that vision recovery of visually impaired patients due to cerebrovascular disorder and the development of the rehabilitation method can be made has become big by this.
