I find intuitions to be very misleading when thinking about consciousness. I can return a similar set of questions to you: which part of your brain do you feel unsure about? The sodium-potassium pumps? The dentate gyrus? The anterior commissure?

RESULTS: Compared with HC, patients with MwoA exhibited significant reductions in GMV in the left amygdala (cluster size =305; FDR-corrected q=0.046), left parahippocampal gyrus (cluster size =273; q=0.036), left lingual gyrus (🧵 8/14)

I gave a talk as well - using small ANN models I showed how circuit organization shapes fast learning and generalization in the hippocampus.

Big computational finding: dentate gyrus at the input stage is necessary and sufficient for fast learning. #cinetconference #neuroskyence 🧠�

We found a top-down alignment in this anterior superior temporal gyrus area: the representation for the 1st, 2nd, 3rd... phoneme peaks at the same moment as the meaning, at a fixed delay after the word starts.

Excited to share that my postdoc work with Timothée Proix
@ndlab.bsky.social is now in Nature Communications!🎉

Recording from 624 human neurons, we show that semantic predictions realign phonetic population activity—revealing how meaning feeds back to reshape speech-sound processing.

I agree. I've been looking into subconscious processing of aphantasia and the fusiform gyrus isn't routed to the hippocampus like those without it. It goes through the amygdala. I can examine my subconscious with the colors we talked about. There are several levels to it. Quite a bizarre experience.

Structural alterations in the superior temporal gyrus associated with depressive symptoms in migraine without aura: a voxel-based morphometry and surface-based morphometry magnetic resonance imaging study
CONCLUSIONS: Patients withMwoA exhibited widespread GMV reductions across brain regions involved in emotional and pain-related processing. In addition, patients with higher depressive symptom levels showed a distinct cortical morphological feature characterized by lower LGI in...

탐색적 부분 상관 분석 결과, FDR 보정 후 어떤 영상 지표도 HAMD-17 점수나 기타 임상 측정값과 유의미한 연관성을 보이지 않았다(모두 q>0.05).

결론: MwoA 환자들은 정서 및 통증 관련 처리에 관여하는 뇌 영역 전반에 걸쳐 광범위한 회백질 부피(GMV) 감소를 나타냈다. 또한, 우울 증상 수준이 높은 환자들은 우측 상측두회(superior temporal gyrus)에서 LGI가 낮은 것을 특징으로 하는 뚜렷한 대뇌 피질 형태학적 특징을 보였으나, (🧵 6/7)

전조 증상이 없는 편두통에서 우울 증상과 관련된 상측두회(superior temporal gyrus)의 구조적 변화: 복셀 기반 형태측정법(VBM) 및 표면 기반 형태측정법(SBM)을 활용한 자기공명영상(MRI) 연구
배경: 전조 없는 편두통(MwoA)은 우울 증상과 빈번히 동반되지만, 이러한 동반 질환의 기저에 있는 신경생물학적 기전은 아직 충분히 규명되지 않았다. 본 연구는 복셀 기반 형태측정법(VBM)과 표면 기반 형태측정법(SBM)을 통합하여, MwoA 환자와 건강한 대조군(HC) 간의 회백질 부피(GMV) 및 대뇌 피질 형태를 비교하고, 우울증 증상 중증도에 따라 분류된 MwoA 하위군 간에 뇌 구조적 변화가 다른지 여부를 추가로 규명함으로써, 이를 통해 이 집단에서 우울 증상의 잠재적 구조적 상...
