In this paper, we are discussing CAUSALITY seriously and how much our beloved Neuroscience has been trapped in the correlational web of non-sensical stuff. It was great to see Shan Siddiqi @shansiddiqi.bsky.social, Michael Fox, Kording Lab 🦖 in action during the writing of this work. rdcu.be/cLLRN

Electrical perturbation of the hypothalamus with implanted electrodes causes raw emotions of shame, sadness & embarrassment w whole body component. "lower" structures and "higher" functions + neurobiology of human subjective experience. Full video: doi.org/10.1016/j.brs.…

(1/8) Delighted to announce our new results on medial frontal cortex’s role in performance monitoring and cognitive control! Neurons formed domain-general representations of errors, conflict, and conflict probability, while preserving task-specific info. science.org/doi/10.1126/sc…

Where fMRI gets it wrong: Less deactivation = activation & native brain space = standard MNI space. What intracranial EEG reveals about the brain's functional architecture in mm scale is astonishing! Fig4 is must see! doi.org/10.1007/s00429…

Initial S.A.F.E.R Trial (MGH, UNM, UWisc & Yale) data presented Neurocritical Care Society today: 295 patients had Ceribell-EEG & 670 had cEEG. Same PREDICTIVE value with both EEGs: If the first 1-hour of Ceribell-EEG has no epileptic abnormality, risk of seizures in the next 72hrs is <5%!!!

Lower motor neuron homunculus! Great essay in Brain. Another reason for moving beyond Corticocentric Myopia. academic.oup.com/brain/article/…

No it is NOT the default mode network! We are reporting a brain region and its connected network that is causally important for constructing a sense of physical self - when perturbed, a sense of dissociation is induced. doi.org/10.1016/j.neur…

"I am a loser." "I am amazing." In depressed and non-depressed patients, OFC responds equally during negative judgments, but OFC responses during positive self-judgments are nearly absent in those with high depression scores! jneurosci.org/content/44/11/…

Decoding the human thalamus: iEEG and stimulation data now shared with anyone interested: doi.org/10.1038/s41593…. Thanks to Vivek P. Buch, MD for great collaboration and for taking us deep inside the human thalamus —what a ride! Also check doi.org/10.1038/s41593… in the same issue.
