I just want to know if anyone knows what drugs affect the red nucleus. Also, what behavior the red nucleus contributes or affects?
Thanks.

What the heck is the red nucleus?? -- sounds like the centre of an atom bomb...

Never heard of the "red" nucleus, but have heard the term "cordate nucleus". are they the same? DOn't know anything else. Bob, oh BOB, are you out there anywhere???

Ok, found my brain anatomy coloring book (I started working on it a couple of years ago and only got through the first few pages). Nevermind my random association to the caudate nucleus (not "cordate"). I found several references to the red nucleus, but this book doesn't say what functions it has, just where it is located, etc.

I think you win, Noa. I just asked my clinical intern partner here and when I mentioned "red nucleus", she responded with "caudate nucleus." She did get an A in neuropsychology, but that *was* over a year ago... she's gonna check her coloring books as well.

I am skeptical about it...I think there are lots of "nuclei" of various sorts, from the looks of the index in my coloring book. Oh well....
Seems you are online right now. Just wanted to say hi.

When I had neuroanatomy we learned that the function of the red nucleus (in the midbrain which is in the upper part of the brain stem)was mostly voluntary movement. It is the origin of something called the Rubrospinal tract--a group of nerves that go to the arms and legs. The other main tract that effects voluntary movement in the arms and legs comes from much further up in the brain--the cerebral cortex (what we usually think of as the "brain"). When someone has a stroke or injury in that part of the brain, the Rubrospinal tract can take over. Another part of the red nucleus is connected to the cerebellum which has to do with movement and balance.

Red nucleus is a structure of the midbrain tegmentum involved in motor movements. It is really small and little is known about its function. Because many fibers or tracts run through it, damages to these tracts affect the red nucleus as well. It is not the same as cordate or caudate nucleus, but sometimes it is also called the ruber nucleus.

I was. Brain bin again. Looks like we were wrong, tho.
