What did Michael Gazzaniga discover in his split-brain research?
Gazzaniga, 71, now a professor of psychology at the University of California, Santa Barbara, is best known for a dazzling series of studies that revealed the brain's split personality, the division of labor between its left and right hemispheres.
What did Gazzaniga do for psychology?
Through his extensive work with split-brain patients, Gazzaniga has made important advances in the understanding of functional lateralization in the human brain and how the cerebral hemispheres communicate with one another.
What did Sperry and Gazzaniga discover?
Working in the lab of Roger Sperry, who later won a Nobel Prize for his work, Gazzaniga discovered that the two halves of the brain experience the world quite differently.
Who discovered the split-brain?
SperrySperry severed the corpus callosum in cats and monkeys to study the function of each side of the brain. He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain.
What happens if your brain is split in two?
Since information cannot be directly shared between the two hemispheres, split-brain patients display unusual behaviours, particularly concerning speech and object recognition.
Do they still do split-brain surgery?
Split-brain syndrome The most common cause is a surgical procedure called a corpus callosotomy, but this is rarely performed today, only for severe cases of congenital refractory epilepsies. It is reserved as the last measure of treatment for extreme and uncontrollable epilepsies.
Do humans have 2 consciousness?
The idea of dual consciousness has caused controversy in the neuroscience community. No conclusive evidence of the proposed phenomenon has been discovered.
What did Roger Sperry and Michael Gazzaniga do quizlet?
What did roger sperry and michael gazzaniga do? They cut the corpus callosum of monkeys/cats in half. What happens in split brain surgery? corpus callosum is cut so the 2 hemispheres can't communicate.
What did Michael Gazzaniga do with split-brain patients quizlet?
Michael Gazzaniga (1967) conducted individual BLANK studies on split-brain patients, so called because each of them had his or her corpus callosum severed.
Why is split-brain important?
For several decades, split-brain research has provided valuable insight into the fields of psychology and neuroscience. These studies have progressed our knowledge of hemispheric specialization, language processing, the role of the corpus callosum, cognition, and even human consciousness.
Who discovered the left and right side of the brain?
Psychobiologist Roger SperryPsychobiologist Roger Sperry discovered that human beings are of two minds. He found that the human brain has specialized functions on the right and left, and that the two sides can operate practically independently.
What can split-brain patients not do?
The canonical idea of split-brain patients is that they cannot compare stimuli across visual half-fields (left), because visual processing is not integrated across hemispheres.
What did Michael Gazzaniga do with split-brain patients quizlet?
Michael Gazzaniga (1967) conducted individual BLANK studies on split-brain patients, so called because each of them had his or her corpus callosum severed.
How did Sperry contribute to our knowledge of brain functioning?
Psychobiologist Roger Sperry discovered that human beings are of two minds. He found that the human brain has specialized functions on the right and left, and that the two sides can operate practically independently.
What did William James study in psychology?
Inspired by evolutionary theory, James's theoretical perspective on psychology came to be known as functionalism, which sought causal relationships between internal states and external behaviors. In 1890 James published a highly influential, two-volume synthesis and summary of psychology, Principles of Psychology.
What did William James believe about consciousness?
The Function of Consciousness James (1890) argued against the structuralist position that states conscious can be broken into constituent parts. Coining the phrase 'stream of consciousness', James proposed that mental life is a unity that flows and changes (thus consciousness is a continuum).

Who did the split brain study?
The Split-Brain study was conducted by Michael Gazzaniga and Roger Sperry. The motivation for the research to do the study in the first place when Sperry and Ronald Myers made a discovery that when the two hemispheres were incised, they saw that “each hemisphere functioned independently as if it were a complete brain” (Gazzaniga). Before the study was done, what the researchers had known about the topic came from Sperry and Myers discovery, research from animal studies, and humans who had undergone a “brain-splitting” operation. The intent of the study was to determine if the hemispheres could function independently of one another when they were separated, in patients who had epilepsy and undergone surgery. Moreover, regarding the study …show more content…
When was insulin discovered?
For example, the discovery of insulin was credited through animal tests in 1922; however, the real finding of insulin was from Thomas Crawley, who performed an autopsy on a diabetic in 1788 which was found by the leading source of pros and cons of controversial topics, the pro con website (5). Although the experiment was falsely credited, the true finding of the cure was performed on a human. Researchers have found that “...human comparisons are necessary to truly understand the root causes of human diseases and to develop effective responses” (Driscoll and Finley 2). If animals do not directly or similarly reflect humans, researchers can find another alternative. Numerous studies do not result in effective outcomes, making it animal testing pointless because it wastes money and lives.…
