Introduction

(Zilmer,2001) is quoted with no full reference. A full reference for that quote would be dandy. — Preceding unsigned comment added by 68.150.60.121 (talk) 00:28, 1 November 2013 (UTC)[reply]

Hemispheric Specialization

Source [9]: Witelson, Sandra F; Wazir Pallie (1973). "Left Hemisphere Specialization for Language in the Newborn". Neuroanatomical Evidence of Asymmetry.(https://www.polyu.edu.hk/cbs/rclcn/images/cdl_articles/W/Witelson__Pallie._1973.pdf) has nothing to do with the claim it is supposed to back up. It is only about language and not once in the article there is mention of "In a cognitive sense the right hemisphere is responsible for recognizing objects and timing, and in an emotional sense it is responsible for empathy, humour and depression. On the other hand, the left hemisphere controls the primary sensory functions of the right side of the body and is responsible for scientific and maths skills, and logic" Am i missing something here ?

I thought the idea "that the left hemisphere is 'analytic' or 'logical' while the right hemisphere is 'holistic' or 'intuitive'" had been disproved. For example, many people simply want to believe logic and intuition are opposites, etc. This is irrelevant here. In fact, I thought fMRI studies showed "thinking about math or logic" looked right-sided on naturally right-handed people. But people writing equations (communicating to others via a language) activate left side areas. But I do not know. This article gives no authority for the statement it makes in this regard. "It is claimed..." Yeah? By whom? This is an encyclopedia. Why not say this is a popular belief with no support. Or else provide the reference. Or remove it for now. I would think somebody has the fMRI study footnotes to fix this by now. --JimRodgers (talk) 07:24, 17 February 2011 (UTC)[reply]

I've added a reference to an article by Dr JR Dew, which expounds the theory. (Personally I am not convinced by it, but it seems to be so widely believed that I think it is worth retaining in the article.) AlanD1956 (talk) 09:57, 15 March 2012 (UTC)[reply]

Under "Corpus callosotomy," the first paragraph has no citations. The second paragraph has one at the end, but it is unclear where (in the cited source) to find the information relayed in this paragraph, even upon further inspection of the source. — Preceding unsigned comment added by 69.207.5.74 (talk) 14:56, 19 May 2015 (UTC)[reply]

Control

"One issue that can happen with their body control is that one side of the body is doing the opposite of the other side called the intermanual effect."

Changed affect to effect. Still not convinced, source would be welcomed. Google not helpful either. Nergar (talk) 21:47, 11 August 2016 (UTC)[reply]

Added citation needed tag. Could it be possible that the intermanual effect is the same as alien hand syndrome? On that page the term "intermanual conflict" is also used.--VeniVidiVicipedia (talk) 11:27, 23 December 2016 (UTC)[reply]

I don't think opposing movement in terms of the movement being mechanically mirrored (which is what the sentence seams to imply) is particularly characteristic of the split-brain condition. In contrast opposing intentions are observed as are involuntary movements. ^[1]--

Also the partial reference

{{Citation needed|date=September 2017|reason=Behavioural Brain Research
Volume 56, Issue 1, 30 July 1993, Pages 43-57|The bilateral reach to grasp movement=}}

seems to describe a movement in healthy individuals and not split brain patients...

Abnormal brains to begin with ?

Just asking ... (84.193.174.59 12:14, 4 March 2006 (UTC))[reply]

Struck me too.

______

They are abnormal in the sense that the person is experiencing epileptic seizures, an electrical storm in the brain if you will, that cannot be controlled by medication. By severing the corpus collosum (the fibres connecting the two hemispheres) you prevent the electrical storm from reaching the entire brain.

"In Arts" section

Split brain in arts sounds like a "Wikipedia euphemism" for split brain in popular culture -- id est, just another trivia section. 69.236.107.118 05:01, 15 July 2007 (UTC)[reply]

Computing

Apparently split brain is a computing term for when computers in a failover/redundant cluster lose communication with each other and things go wrong. I don't really know the details. 131.111.245.195 (talk) 00:36, 22 January 2009 (UTC)[reply]

Religion/Philosophy

Even accepting the gross oversimplification of some of the traits listed as particular to each hemisphere, what is philosophy doing on the right (or indeed on any side)? Logic, the discipline, is a formal sub-discipline of philosophy. But logic is listed as a left-brain trait. This portion of the article isn't even coherent. — Preceding unsigned comment added by 98.209.89.113 (talk) 22:59, 19 November 2011 (UTC)[reply]

Yes, that section was pop-sci hokum, with a reference nowhere near satisfying WP:RS. Nixed. --David-Sarah Hopwood ⚥ (talk) 23:57, 7 January 2012 (UTC)[reply]

Non-invasive Corpus Callosotomy?

"Using new technology, a machine called the diffusion tensor magnetic resonance image, allows for a non-invasive procedure that does a bisection of the anterior ⅔ of the corpus callosum for patients that suffer for severe epilepsy that even anticonvulsive medications will not work; it has been deemed as a successful procedure" Is this correct? — Preceding unsigned comment added by Seemannstreue (talk • contribs) 18:39, 18 July 2014 (UTC)[reply]

This is not correct at all - DTI is an imaging technique, which should be apparent from the abstract of the referenced paper. There is no non-invasive way to bisect the corpus callosum, and I would suggest that this sentence and the reference are removed from the article. — Preceding unsigned comment added by 194.75.37.250 (talk) 10:10, 4 December 2014 (UTC)[reply]

Further to my above comment, I have removed the sentence. I have left the reference in place however, as it is referenced again later in the section. — Preceding unsigned comment added by 194.75.37.250 (talk) 10:25, 4 December 2014 (UTC)[reply]
