“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”
Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification
Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

New paper with Marina Bedny out in eLife (elifesciences.org/articles/101...). Main takeaway: Different kinds of causal knowledge are supported by different semantic brain networks - consistent with the "intuitive theories" framework from developmental psychology. 1/
Animacy semantic network supports causal inferences about illness
Making causal inferences about illness, compared to making causal inferences about mechanical breakdown and reading causally unconnected sentences, activates a semantic brain network implicated in the conceptual representation of animate entities (e.g. people, animals).

proud to share this work, led by the brilliant @ilinabg.bsky.social, now out in Nature! Ilina finds that speech-sound neural processing is VERY similar in a language you know and one you don't. differences only emerge at the level of word boundaries and learnt statistical structure 🧠✨
The human brain responds to the sounds of both familiar and unfamiliar languages in a similar way, according to research in Nature. The findings might guide future approaches to language learning and rehabilitation. go.nature.com/4ppvsHb #Neuroskyence 🧪

Half your brain cells are astrocytes, oscillating and modulating activity without spiking, while cortical neurons spike sparsely. So nearly 100% of cells are oscillating almost all the time, but only a minority of cells emit rare spikes. Maybe spikes are the tail and oscillations are the dog.

You can't dissociate spiking and LFPs oscillations. They are the same system. Anything that changes spiking will affect oscillations and vice versa. Funny how people hold oscillations to a higher standard than spiking. That is just paradigm defending.
