Talk:Cerebral cortex

Picture

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?

Location

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?

As of Oct. 2016, "The cerebral cortex is the cerebrum's (brain) outer layer of neural tissue...", and the accompanying picture says, "The cerebral cortex is the outer layer depicted in dark violet."UnderEducatedGeezer (talk) 00:21, 17 October 2016 (UTC)

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 @Neuron Doc:, 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)

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)

@SamuelRiv, Looie496, Tryptofish, Lova Falk, and Iztwoz: I appologize for the scattershot notification to you all, but I have developed a respect for your knowledge, & really think that the lede by @Neuron Doc: 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...".

Thanks for making the change @Iztwoz:! UnderEducatedGeezer (talk) 10:21, 5 December 2018 (UTC)

Needs more - lead is not proper summary....Best --Iztwoz (talk) 10:37, 5 December 2018 (UTC)

Thanks for the ping. Iztwoz, I'm juggling a lot of stuff right now, but please let me know if there is anything in particular here that you would like me to help with. --Tryptofish (talk) 18:22, 5 December 2018 (UTC)

Thanks for that Tryptofish.--Iztwoz (talk) 20:05, 5 December 2018 (UTC)

Jorge in intro

"In large Jorge the surface of the cerebral cortex is folded,..." Is this a typo or should 'Jorge' be defined? Romanfall (talk) 05:22, 28 February 2014 (UTC)

Seems like a rogue edit and so removed it Iztwoz (talk) 09:44, 28 February 2014 (UTC)

Comparison of neuron count with other mammals

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 .

Primary regions vs Association area

In the part about Association area it is said that Association areas do not belong to Primary regions. I deduce that the Primary regions are the motor and sensory areas. These are not defined as primary in the text, as far as I can see. I suggest therefore a change. Suturn (talk) 08:06, 17 October 2025 (UTC)
