Definition

I'm missing a short definition of cerebrum in the first sentence and/or disambiguation hatnotes. Is cerebrum a part of the brain, a synonym for brain or just the latin word for human brain? Isheden (talk) 16:37, 20 September 2013 (UTC)[reply]

Done (not by me though). Lova Falk talk 16:12, 4 October 2013 (UTC)[reply]

I will be adding citations for the Structure and Function sections of this page. Changes should be minimal, unless I find inaccuracies in the information. Lehession (talk) 11:55, 21 January 2015 (UTC)[reply]

"Superior-most region"

The beginning of the article says that "the cerebrum is the superior-most region of the central nervous system". While, as a layman in this area, I do have an idea of what "superior-most" mean (my guess is "uppermost" in a standing human), I am not sure, and even when I followed the link to superior-most and tried to read what it said there, I still found no answer; I was actually just more puzzled (or confirmed in my uncertainty), as it says this:

"In Man, the directional terms "superior" and "inferior" essentially refer to this rostrocaudal dimension, because our body axis is roughly oriented vertically in the erect position. However, all vertebrates develop a kink in the neural tube that is still detectable in the adult central nervous system, known as the cephalic flexure. The latter bends the rostral part of the CNS at a 90 degree angle relative to the caudal part, at the transition between the forebrain and the brainstem and spinal cord. This change in axial dimension is problematic when trying to describe relative position and sectioning planes in the brain."

What I am left with is only an "essential" (non-complete) definition and a statement that it is "problematic", and I am still not sure if "superior-most" means "uppermost" or "frontmost" when talking about the brain or the nervous system.

This might mostly be a problem with the section "Orientation in neuroanatomy" in the neuroanatomy article (it is not very easy to read if you just want a quick answer for a human orientational term, as the article tries to be general for all animals), but it could also help if it was made clearer in this article, for instance by stating " (uppermost)" or " (frontmost)" after "superior-most".

I was also thinking about changing the "superior-most" link to refer to Anatomical terms of location#Superior_and_inferior instead, as it gives a more direct description of superior and inferior which leaves me 99% sure it means "uppermost" (or "uppermost in a standing human") in this case.

Can anyone medically educated (or anyone through a credible reference) clear the last 1% of doubt in me? Does superior-most mean uppermost in this case? --Jhertel (talk) 19:03, 3 June 2016 (UTC)[reply]

Hi Jhertel it can only mean uppermost in the context - unless somebody knows better! Have changed it. cheers --Iztwoz (talk) 21:11, 3 June 2016 (UTC)[reply]

Phylogeny

I deleted the sentence ″The cerebrum is the newest structure in the phylogenetic sense, and in mammals it is the largest and most developed, out of all known species.″ Reason: The cerebrum is not phylogenetically newer than other parts of the brain: every known vertebrate, extant of fossil has (had) a cerebrum. The second part of the sentence is meaningless nonsense (if it is to refer to the large human cerebrum, elephants and some whales have bigger cerebrums). Marci68 (talk) 08:00, 28 September 2017 (UTC)[reply]

the second part doesn't seem to be meaningless nonsense, but just a gross summary of different proportions of the brain parts, in different branches of animals, which seems to be roughly correct, if these diagrams are representative of the groups. I don't see why humans specifically would be implicitly the only "mammals" on the phrase. And even the preceding part is arguably just a somewhat poor phrasing of evolutionary history. The brain didn't arise "fully formed" in evolution, even if a primitive telencephalon was already present in the earliest vertebrates. It's absent in amphioxi and tunicate larvae, AFAIK, although researches speculate potential analogies between it and their primitive ganglia. Once the "tripartite" brain is fully there, its parts don't evolve all at the same rate, but there's this "correlation" of further development of the telencephalon in more "advanced" animals, with things like the already mentioned proportionately larger cerebrum in mammals, but also extant birds having it larger than their dinosaur relatives and even extinct birds, phylogenetically more basal. — Preceding unsigned comment added by 45.234.133.142 (talk) 17:20, 13 March 2023 (UTC)[reply]

Lobes of the brain

In this article and in the text of the illustration the four lobes are summed up incorrectly as the frontal, parietal, temporal, and occipital lobes.

Embryologically, the (human) cerebrum is a c-shaped structure and therefore the four lobes of its cortex (frontal, parietal, occipital and temporal) are named in a specific order, as indicated in the anatomy template below and in wiki/Cerebral_cortex and Lobes_of_the_brain. --Tmajoor (talk) 09:04, 10 May 2018 (UTC)[reply]

You are welcome to edit the article to change this, but I wouldn't say that "incorrect" is quite the right word. With the exception of the frontal-parietal boundary (which follows the central sulcus), the lobes are defined by the overlying bones of the skull and not by any aspect of internal brain structure, so the rules governing their use are essentially arbitrary.

Self-referential etymology

Can anyone explain what the article means by "The Latin word cerebrum comes from Latin cerebrum, meaning 'brain'."? Because to me this sounds like a joke from a Clyde Crashcup cartoon. — Preceding unsigned comment added by 64.121.6.113 (talk) 19:00, 28 May 2018 (UTC)[reply]

Translations

Greek: ο άνωνους (masculine) (νους etymologically means mind and not brain, but etymology is not the same as meaning/definition/word interpretation)

Telencephalon

"Telencephalon" redirects to this page, and is used on the body of the article, but is not explained. I have found some sources that says the telencephalon and the cerebrum are the same thing, while others say "The telencephalon includes the cerebrum and olfactory bulbs". This is a key piece of terminology that should be explained at the top of the article. Jess_Riedel (talk) 15:37, 1 October 2018 (UTC)[reply]

In any case, there's no purpose in having a link for "telencephalon" if it merely redirects to the same page (Cerebrum). I'd remove the link.Omc (talk) 02:29, 6 March 2019 (UTC)[reply]
