What role do cortical regions play in #mathematical learning? This study reveals the causal role of dorsolateral #PrefrontalCortex & #frontoparietal network in #math learning using #transcranial neuromodulation in human participants @PLOSBiology plos.io/45SyMUI

Top left: Calculation problems (denoted by “§”) began with the presentation of a problem, a brief mask, and an unlimited input duration. Upon giving the correct response, the participant was presented with a new problem. Incorrect responses led to the repetition of the same problem until the correct response was provided. Bottom left: Drill problems (denoted by “♯”) were presented as a combination of two operands and an outcome. In contrast to the calculation problems, in the drill problems, the underlying algorithm to derive the result by calculation was not known. The combination had to be memorized and reproduced after masking. Both presentation time and response input time decreased from one session to the next, overall. Problems were repeated when answered incorrectly. Right: A 3D volume, generated manually in CONN, depicting the four frontoparietal seeds (left dlPFC, right dlPFC, left PPC, right PPC) as well as the right and left frontoparietal connectivity that was used in the functional connectivity analyses.

The medial #PrefrontalCortex (mPFC) is a key brain area for pain sensation & #ChronicPain. This study shows that modulation of a circuit projecting from nucleus reuniens of the thalamus to mPFC improves neural & behavioral indicators of chronic pain in mice @PLOSBiology plos.io/4mpMuEj

RE neurons respond to pain-like stimuli, emotional changes, and social interaction in SNI mice. Top: Diagram of virus injection (left) and an example image (right) of GCaMP6s expression in the RE. Bottom: Heat maps of changes in GCaMP6s and eYFP signals in the RE in response to von Frey filament (vF) stimulation on the injured hind paw in SNI or sham mice.

@mick
Cool stuff, congrats!!
Were there no connections between Nucleus Reuniens and Dentate Gyrus or CA3?

I also wonder what you think of this commentary on Ito et al., 2015, by Blake Porter: blakeporterneuro.com/writing/s 👀

Really interesting preprint from researchers at on characterising activity in shared communication between the and the . I found it particularly intriguing that theta power appeared to decrease subspace dimensions and increase subspace predictability, while theta had much less of an effect. biorxiv.org/content/10.1101/20

Maybe I did it, somehow...

Matter is: now my #prefrontalCortex is #inControl , while my #limbicSystem is not, not anymore, and has to ask the former #whatShouldILike ...

Ravens and parrots with brains of 5–20 grams demonstrate cognitive abilities similar to those of great apes, whose brains weigh approximately 400 grams. 😮 An interesting article about why birds can support complex cognition with such small brains + a hypothesis about the minimum neurological requirements for this:

@Learning @cogneurophys some gems in there we take for granted now, but went against the grain or were simply unknown at the time. Remarkable opus. #prefrontalcortex #neuropsychology #HippocampusGurus #HippocampusHistory #neuroscience #cognitivepsych
