In line citations

Please use inline citations. The current method, employing "sup" and "/sup" tags, is incredibly difficult to work with, and doesn't provide any of the benefits of the standard method of citation.Fuzzform (talk) 05:09, 1 March 2009 (UTC)[reply]

The anatomy section is unwieldy. It needs reorganization and clarification.Fuzzform (talk) 05:24, 1 March 2009 (UTC)[reply]

The reference "Crutcher, Michael D. Telephone Interview. 19 November 2008." cannot be found via google or any other search method. It needs to be clarified.Fuzzform (talk) 05:52, 1 March 2009 (UTC)[reply]

Is the picture correct ?

The purple region seems the striatum, ie to include both the caudate and outer/lateral part of the striatum, the putanem. The orange region seems like it could be the thalamus... 70.81.15.136 (talk) 12:04, 12 May 2009 (UTC)[reply]

You're definitely right, thanks for catching the error -- I've changed it. Looie496 (talk) 14:45, 12 May 2009 (UTC)[reply]

confusing study

It says samples were taken and made into lines... why not words?

And it says the categories were rotated. Shouldn't we say the lines were given two categories and they had to separate? —Preceding unsigned comment added by 173.16.38.68 (talk) 11:01, 29 January 2010 (UTC)[reply]

This is a low-quality article, and I recommend against taking anything in it seriously unless you verify it from the source. I really don't even think that experiment is notable enough to be worth describing here. Looie496 (talk) 16:09, 29 January 2010 (UTC)[reply]

Unecessary mention of trans women

It's well-documented that there are sexually dimorphic brain areas. It's also well-documented that the brains of trans individuals, as they transition, change i.e. a trans woman's brain becomes more similar to that of a cis woman's. This section says that the putamen of trans women is different than that of a typical biological male. This is neither interesting nor novel, and therefore doesn't need to be here at all.

Even the next sentence "this possibly suggests that a fundamental difference in brain composition may or may not exist between trans women and biological men" is a useless read. It not only suggests nothing, but it also contradicts the sentence right before it. There are plenty of other wiki articles that cover sex, transgenderism, and neurology that also happen to contain real scientific claims, facts, and appropriate descriptions.

Can we please remove this? Doughpamine (talk) 05:29, 12 February 2023 (UTC)[reply]

Edit: I have read through the study, and now understand why this fact was inluded. I want to find an appropriate way to specify in the article that the MTF individuals from the study were not yet treated with feminizing hormones, and that is why this anatomical difference is noteworthy. — Preceding unsigned comment added by Doughpamine (talk • contribs) 06:32, 20 February 2023 (UTC)[reply]

Wrong information given about dopamine release

The following section is wrong. Or written in a way easy to misunderstand:

Wikipedia: "When a cell body of a neuron (in the putamen or caudate nuclei) fires an action potential, dopamine is released from the presynaptic terminal." Since projections from the putamen and caudate nuclei modulate the dendrites of the substantia nigra, the dopamine influences the substantia nigra, which affects motor planning."

The cell bodies of the dopaminergic neurons are located in the substantia nigra. The axons of these dopaminergic cells project into the striatum and thus dopamine is released into the striatum. This is called the nigrostriatal pathway.
