	Seeing what you don't see? (Site not responding. Last check: 2007-10-10)
		The phenomenon, called "blindsight", is one of the more dramatic of a number of lines of evidence suggesting that being aware of doing something is distinguishable from doing something, that areas of the brain underlying the experience of doing at least some things are distinct from those needed to actually do those things.
		Blindsight - the ability to respond appropriately to visual inputs while lacking the feeling of having seen them - might be something which only occurs in cases of brain damage, but seems much more likely to be a significant phenomenon of intact brain function as well.
		Blindsight by L. Weiskrantz (Oxford, 1986) is a valuable monograph by one of the pioneer investigators of the phenomenon.

	20th WCP: Blindsight and the Role of the Phenomenal Qualities of Visual Perceptions
		Since blindsighted persons receive informations without conscious perception, blindsight is often understood as supporting the claim that the phenomenal qualities of visual perceptions do not have a function for the information-processing which gives rise to their intentional contents, and, consequently, that they are not intentional qualities.
		Blindsight is a defect which some persons suffer from as a result of a partial damage of their primary visual cortex.
		Blindsight is remarkable because of the contrast between the lack of declarative knowledge of the blindsighted persons about the stimuli presented within the blind area, and the high rate of correct answers to questions concerning those stimuli.

	Blindsight (Site not responding. Last check: 2007-10-10)
		However, it can be seen in blindsight research that behavior can be directed in a zombie-like fashion due to the unconscious processing of these stimuli indicating that conscious awareness is not a sufficient requirement to behave in the world.
		This is not to say that blindsight subjects are limited to the mere detection of stimuli, but rather have been able to discriminate stimuli on multiple dimensions as described in Weiskrantz (2003).
		It is of importance to note that the blindsight sight evidence is based upon a small population of intensely studied subjects and not all subjects display all capabilities.

	Blindsight and Consciousness (Site not responding. Last check: 2007-10-10)
		As stated above, blindsight is seen clinically as a contrast between a lack of declarative knowledge about a stimulus and a high rate of correct answers to questions about the stimulus (1).
		The damage in blindsight patients has been shown to be in the striate cortex, which is part of the visual cortex.
		He explains blindsight as a representation of absence of information about visual stimuli, so that no information about the visual stimuli enters in to the drafts while they are being written in the brain (4).

	Mystery of "Blindsight" Lets Some Blind People "See," Study Shows (Site not responding. Last check: 2007-10-10)
		The phenomenon of "blindsight" occurs in some people who suffer injuries to the primary visual cortex, the region of the brain considered essential for sight.
		Blindsight allows people to use visual information they get through their eyes even though they have no consciousness of the visual experience, said Christopher Mole, a postdoctoral fellow in philosophy at Washington University in St. Louis, Missouri.
		Blindsight is most prevalent among people who suffer damage to the primary visual cortex, such as in some stroke victims, Mole explained.

	Blindsight - Wikipedia, the free encyclopedia
		However, the route from retina through V1 is not the only visual pathway into cortex (though it is by far the largest); it is commonly thought that the residual performance of people exhibiting blindsight is due to preserved pathways into extrastriate cortex that bypass V1.

	Zombies Dolphins and Blindsight
		Blindsight is possible, the neurologists assume, because the visual pathway splits into many parallel streams as it approaches the cortex and some streams go on to different parts of the brain, bypassing the primary visual cortex.
		Blindsight can thus give clues as to which parts of the brain are essential to generate consciousness.
		Induced blindsight work is most promising since it deals with normal subjects.

	Psyche 7(4): Who Is Blind to Blindsight? by Peter Carruthers
		Although the phenomenon of blindsight is, initially, highly counter- intuitive, it is not especially surprising when seen from the perspective of neurophysiology.
		The explanation of blindsight, therefore, is that visual information is still available (in parietal cortex) to control movement, which is not available (via temporal cortex) for conscious awareness.
		This is a form of self-prompting blindsight, in which a subject would spontaneously entertain the very same kinds of thought which actual blindsight patients voice in forced-choice experimental situations (e.g., "horizontal" or "vertical" when asked to guess the orientation of a grating).

	Mechanism of 'blindsight' explored
		Blindsight is a phenomenon in which people with a deactivated primary visual cortex -- an area of their brain essential for visual perception -- can still sense objects in their field of vision.
		Blindsight seems to confirm that the skin acts like a potential portal of info as well as quasi retina for the sightless and has about the same number of axons as the retina feeds into the optic nerve.
		Empirical data on blindsight seems to support our theory of "Biophysics Resonance" whereby our "bandaid for the blind" can paint video pictures with dots of heat (IR) instead of light using AM TFT active matrix of thin film transistors extracted from LCD used in cell phones.

	Blindsight Also Occurs In Monkeys
		One explanation of blindsight maintains that the visual cortex has not been totally destroyed, and that functional remnants remain.
		Therefore, blindsight does not seem to be "suboptimal functioning" of a damaged brain -- at least in monkeys.

	Psyche 7(08): "Spontaneous Blindsight and Immediate Availability: A Reply to Carruthers" by Charles Siewert
		After all, I explicitly say that, in conceiving of spontaneous amblyopic reflective blindsight, I do not ask the reader to assume that such feats of visual discrimination without visual experience are compatible with the natural organization and functioning of the human nervous system (pp.
		First, he says that I ask us to construe "blindsight cases" so broadly "as to cover anything described in any proposed reductive explanation of consciousness." And that is merely to define blindsight so as to rule out any successful reductive explanation of consciousness--which surely is to assume what is to be shown.
		I can conceive of a case-a spontaneous blindsight case--in which it seems one would have all that one needed to count as the possessor of a visual state whose content is immediately available to higher order thought, in Carruthers' sense, while one lacked the relevant conscious visual experience.

		A temporal /nasal asymmetry for blindsight: Evidence for extrageniculate mediation.
		MP was tested in a 2-alternative forced-choice localisation task, with either the right eye or the left eye patched in separate blocks.
		The temporal/nasal asymmetry is consistent with blindsight in MP's hemianopic field being mediated by a subcortical, extrageniculate route.

	Blindsight of a Parked Car
		The term "blindsight" is normally used to describe the subconscious visual perception that has been found in some blind people: these blind people perform better than chance would predict when asked to point at visual events, although they have no conscious perception of light or sight.
		Brain scans appear to confirm that people with blindsight do not "fake" their lack of conscious visual perception.
		No blindsight in the conventional sense is required or involved here.

		Blindsight takes on the evolutionary benefits of sociopathic behavior, and the ethics of torture, the puzzle of sentience, and what it means to intentionally develop a simulacrum of empathy and conscience (and whether it's worthwhile to do so).
		Blindsight isn't about aliens or vampires or the future of technology.
		Anyway, if you'd like to wrap your copy of Blindsight (or some other book, for that matter) in something just as authentic, but different from the official release -- or, if you just want a taste of some of the other jacket concepts that floated around "Blindsight" during production -- go to www.rifters.com.

	The Emperor's New Mind
		But there are other experiments which appear to suggest that some parts of the cerebral cortex are more to be associated with consciousness than are others.One of these has to do with the phenomenon of blindsight.
		Damage to a region of the visual cortex can cause blindness in the corresponding field of vision.If an object is held in that region of the visual field,then that object will not be perceived.Blindness occurs with respect to that region of vision.
		All this seems to show that some areas of the cerebral cortex (eg the visual cortex) are more associated with conscious perception than are other areas,but that with training,some of these other areas can apparently be brought within the scope of direct awareness.

	Blindsight \| Book Reviews \| SCI FI Weekly
		The series that began with his first novel, Starfish, also featured a crew of tough-to-love maniacs living in isolation from humanity.
		No matter how wild the material he puts before readers—invisible aliens, paleogenetics, a vampire's inability to deal with a crucifix—it is heavily researched and convincingly sold.
		Blindsight throws down a challenge to every banal first-contact tale that features quirky but ultimately lovable life forms, novels where humanity meets up with bipedal, oxygen-breathing aliens whose primary differences from ordinary people can be resolved with some empathy and fast talking.
