Split-Brain: What We Know Now and Why This is Important for Understanding Consciousness
The idea of split consciousness in a split-brain had its origin in the early split-brain studies (Gazzaniga, 1967; Gazzaniga, 1975; ... But crucially, the latter was the case, independent of whether the patient responded with the left or the right hand. Thus, it seems that in split-brain patients perceptual processing is largely split, yet ...

Metrics. Since the 1960s, researchers have been scrutinizing a handful of patients who underwent a radical kind of brain surgery. The cohort has been a boon to neuroscience — but soon it will be ...

Split brain: divided perception but undivided consciousness. In extensive studies with two split-brain patients we replicate the standard finding that stimuli cannot be compared across visual half-fields, indicating that each hemisphere processes information independently of the other. Yet, crucially, we show that the canonical textbook ...

The term "split-brain" refers to patients in whom the corpus callosum has been cut for the alleviation of medically intractable epilepsy. Since the earliest reports by van Wagenen and Herren and Akelaitis (1941, 1943) on the repercussions of a split-brain, two narratives have emerged.First and foremost is the functional description, pioneered by Gazzaniga, Sperry and colleagues (Gazzaniga ...

Interaction in isolation: 50 years of insights from split-brain
Introduction. Fifty years ago, one of the first studies that showed the neuropsychological consequences of sectioning the corpus callosum, that great bundle of fibres that connects the two cerebral hemispheres, was published in Brain (Gazzaniga and Sperry, 1967).With the help of several patients who have undergone this procedure and generously given of their time as willing participants in ...

Discovering the split mind
W.J. was the first of a series of split-brain patients that the Sperry laboratory would study. Their data provided some of the clearest evidence then of the functional differences between the hemispheres. The test with blocks suggested, for example, that the right hemisphere excelled at visuospatial tasks, compared with the left hemisphere.

A split-brain case study on the hemispheric lateralization of
Split-brain patients lack commissural fibers for inter-hemispheric communication, and therefore the hemisphere that processes a visual stimulus must complete the task indicated by the stimulus. Thus, presenting a task in the lateral visual field of a split-brain patient can isolate the function of a single hemisphere.
Split-Brain Patient
Abstract. Split-brain patients constitute a small subpopulation of epileptic patients who have received the surgical resection of the callosal fibers in an attempt to reduce the spread of epileptic foci between the cerebral hemispheres. The study of callosotomy patients allowed neuropsychologists to investigate the effects of the hemispheric ...

Biopsychology: Hemispheric Lateralisation & Split Brain Research
Split-Brain Research Sperry and Gazzaniga (1967) were the first to investigate hemispheric lateralisation with the use of split-brain patients. Background: Split-brain patients are individuals who have undergone a surgical procedure where the corpus callosum, which connects the two hemispheres, is cut.

The split-brain: Rooting consciousness in biology
The Sperry laboratory was going full tilt with experiments of all kinds on the so-called "split-brain" ( 1 ). Cats and monkeys were the main animals, and the results were clear and riveting. Train one side of the brain on a sensory task, and the other side didn't know anything about it.
