Talk:Cerebral cortex

message: The image captioned "Location of the Cerebral cortex" should really be replaced.  It (regardless of source) is highly inacurate.  The blood vessles are all in the wrong places, the thalamus is about four times too big, and the pattern of invaginations show severe departures from reality, most notably the lack of a temporal lobe, sylvian fissure, or central sulcus.  Does anyone have a better picture?

replies: text:  Can the above description of location be re-added past it's deletion? I notice that as of 8/30/18, that description of location of the cerebral cortex is missing, replaced by a rewrite of the introduction on July 6, 2017 by , which rewrite does not now include a description of its location. Since the person who asked about the location of the Cerebral Cortex, and myself, and probably many other non-neuroscientists may not have (or had) any idea at all where the cortex of the cerebrum is located, I wonder if the description I mentioned above could be re-added to the beginning of the introduction?  I respect the fact that many people, including Neuron Doc, know a lot more about the brain than I do, but I think the location, what it does, what it's made of, and its structure are basic things which deserve to be mentioned in the introduction. I hesitate to re-add it myself, out of respect for those who are more knowledgeable than I. UnderEducatedGeezer (talk) 02:25, 31 August 2018 (UTC)
replies: text:  I do question the statement, "The cerebral cortex is the most anterior (rostral) brain region...", as it's my understanding that the cortex of the cerebrum is the entire outer surface of the cerebrum (minus the meninges), including all lobes, as well as the medial surface and the insula. And I think it's not the cortex that's divided into two hemispheres, but rather the cerebrum itself, yielding two cerebral hemispheres. UnderEducatedGeezer (talk) 02:25, 31 August 2018 (UTC)

text:    I appologize for the scattershot notification to you all, but I have developed a respect for your knowledge, & really think that the lede by  has some very misleading statements, in that it conflates cerebral CORTEX with the whole CEREBRUM itself, speaking of the cerebrum itself as if it IS the cerebral CORTEX, & is therefore VERY misleading. Eventually I will try to fix it, I'd just like to see someone else acknowledge that the items I've mentioned in my messages above this one are valid concerns.  I think "The cerebral cortex is the cerebrum's outer layer of neural tissue..." would be a good & reasonable start, as well as removing, "... is the most anterior (rostral) brain region...".

thread_title:  Picture 

message: Where in the brain is the cortex located? All i've found is the picture, and it's not very precise. If it is indeed said in the text of the article, perhaps it needs rewording?

thread_title:  Location 

message: There are references to homotypic, heterotypic and heterogenetic - none of which explained - I can only find them used in botanical texts.  Any objections to their removal? Iztwoz (talk) 13:31, 29 September 2013 (UTC)
replies: text: Well, parsing the Greek I expect that the words mean "usual", "unusual", and "unusual in origin".  But I don't recall ever seeing that terminology, and I certainly don't have any objections to removing it. Looie496 (talk) 15:16, 29 September 2013 (UTC)

message: The numbers specified by 78.30.129.166 are wrong. While the elephant cerebellum has ~250 billion neurons as opposed to the ~70 billion of the human cerebellum, the elephant cerebral cortex has only 5-6 billion neurons as opposed to the ~20 billion of the human cerebral cortex http://nautil.us/issue/35/boundaries/the-paradox-of-the-elephant-brain.
