Split-brain

Our brain is divided into two halves or hemispheres. The left hemisphere specializes in language, words, understanding and reasoning while the right hemisphere is associated with spatial awareness and creativity. Split brain is a term used to describe the result when the corpus callosum connecting the two hemispheres is severed either partially or completely. Before the proceeding with the surgical procedure, the patient’s head is either partially or completely shaven in order to gain easier access

Running Head: SPLIT BRAIN LATERALIZATION Difference of Lateralization Between Split Brain And Intact Brain Patients Psychology 102 Section 6X Student Abstract Split brain patients lateralize functions in their brains to either side of the brains while intact brain patients utilize both sides of their brains. A group of 20 subjects were tested, 10 split brain and 10 intact brain patients. We gave these subjects three exams, a vocabulary test, a logical reasoning task and a face

Split-Brain Research History of split-brain research Walter Dandy, an American neurosurgeon unintentionally paved the way into research on split-brain patients in the 1930s. Split-Brain refers to patients who have had their corpus callosum severed to some extent or in whole. This procedure was mainly used as an extremely invasive surgical procedure within patients suffering from intractable epileptic seizures. The corpus callosum consists of over 200 million nerve fibres connecting the left and

a normal function brain and split brain allows us to appreciate the fact that much of our processing takes place outside of conscious awareness is that since our brain keep working and keep processing the information, even though some of us have split brain due to some disease call epilepsy (seizure), it allow us to realize that it won’t stop the brain to work from having a split brain but maybe it will give us some kind of abilities to do something that a normal function brain person can’t do. We

Split-brain syndrome, also referred as callosal disconnection syndrome will be a condition that is distinguish by a bunch of neurological abnormalities that emerge from either a partial or a complete lesioning or severing the corpus callosum, which is basically the cluster of nerves that connect the left and right hemispheres of the brain. It is still not fully understood whether or not the action of certain tasks is actually dependant on both of the brain hemispheres, because they both appear to

Split brain studies provided a great opportunity to understand how the two hemispheres different in face processing. Split brain monkey study has provided a general idea that the left hemisphere is better at distinguishing tiled lines and the right hemisphere is better at discriminating faces (Hamilton & Vermeire, 1988). Human split brain case on face processing provided a more detailed result that left hemisphere

would have a split brain, I don’t believe I would act any differently than I act now. The only way to actually notice the differences is when you put yourself through tests. However, if it was a special case, I might not be completely functioning. I would have trouble telling my body what actions to perform. Split brain occurs when there is a lack of a corpus callosum or when the corpus callosum is severed. Making it so there is no connection between the two hemispheres of a person’s brain. A person

For more than a century ago, clinical observations had shown the brain to be multifocal as well as two sided, providing different functions. Knowing that the corpus callosum would have to be severed, in 1961 neurosurgeons Philip Vogel and Joseph Bogen and the rest of the team including Roger Sperry and his graduate student Michael Gazzaniga wondered and communicated about cutting short communications to lower seizure rates by cutting the corpus callosum. The process and technique of this brilliant

work focused on the left and right hemispheres of the brain (Hockenbury and Hockenbury 2014). Roger Sperry’s area of research was categorized as neurophysiology. Sperry’s most famous research dealt with split-brain operations where the corpus callosum has been completely severed (Hockenbury and Hockenbury 2014). The corpus callosum consists of a bundle of neurons that are responsible for the communication between the two hemispheres of the brain. The severance of the corpus callosum was performed in

Question 1 Discuss the literature on split-brain and lateralization of function. What does the research tell us about each hemispheres ability to function independently (e.g., cognitively, creatively, etc.) and in unison? What are the implications for the cognitive neuroscientist in terms of research? Even though a variability of neurochemical and neuroanatomical sections are involved in the preparation of memory, functional specialization significantly regulates what kind of material can be learned
