Human stereoEEG recordings reveal network dynamics of decision-making in a rule-switching task - Nature Communications

How sensory evidence is transformed into motor output is not fully understood. Here, the authors use stereoEEG recordings during a rule-switching task to reveal network dynamics of decision-making.

Last week, Nicole Liddle (Sr. Clinical Research Specialist) presented Zilio, Gomez-Pilar and colleagues’ 2021 paper on how intrinsic neural timescales (INTs) relate to sensory vs. motor processing in abnormal states. This 🧵 explores her thoughts (🤍 & ❔) www.sciencedirect.com/science/arti...

Are intrinsic neural timescales related to sensory processing? Evidence from abnormal behavioral states

The brain exhibits a complex temporal structure which translates into a hierarchy of distinct neural timescales. An open question is how these intrins…

Flexible recruitment of memory-based choice representations by the human medial frontal cortex

Information stored in memory is selectively routed to the human frontal cortex only when a decision requires access to memory.

Last week, Ahmed Hadwan (3rd Year Undergraduate student, Duke Kunshan University) presented Alex Silva and colleagues’ new paper on shared cortical articulatory representations between languages for BCI. This 🧵 explores his thoughts (🤍 & ❔) www.nature.com/articles/s41...

A bilingual speech neuroprosthesis driven by cortical articulatory representations shared between languages - Nature Biomedical Engineering

Multilingual articulatory representations in the speech-motor cortex of a participant with vocal-tract and limb paralysis enabled the development of a bilingual speech neuroprosthesis.

Last week, Aaron Earle-Richardson (Research Tech) presented Arthur Pellegrino and colleague’s new paper on Dimensionality reduction beyond neural subspaces with slice tensor component analysis. This 🧵 explores his thoughts (🤍 & ❔) www.nature.com/articles/s41...

Dimensionality reduction beyond neural subspaces with slice tensor component analysis - Nature Neuroscience

Neural activity does not always lie in a low-dimensional subspace. The authors extend this classic view to show that task-relevant information is distributed across multiple covariability classes and ...

This week, Nicole Liddle (Sr. Clinical Research Specialist) presented @lauragwilliams.bsky.socialwww.biorxiv.org/content/10.1...

Hierarchical dynamic coding coordinates speech comprehension in the brain

Ramping dynamics and theta oscillations reflect dissociable signatures during rule-guided human behavior - Nature Communications

The authors show that neuronal populations in the human prefrontal-motor network interact via two discernible communication modes – ramping dynamics and neural oscillations. These modes operate in con...

Last week, Ahmed Hadwan (3rd Year Undergraduate student at Duke Kunshan University) presented Ariel Goldstein and colleagues’ new paper on shared geometrical patterns between contextual linguistic embeddings and brain embeddings. This 🧵 explores our thoughts (🤍 & ❔) www.nature.com/articles/s41...

Alignment of brain embeddings and artificial contextual embeddings in natural language points to common geometric patterns - Nature Communications

Here, using neural activity patterns in the inferior frontal gyrus and large language modeling embeddings, the authors provide evidence for a common neural code for language processing.

The CoganLab is looking for a postdoc to work on intracranial recordings of speech. Projects include speech production, verbal WM, and decoding for neural speech prostheses with micro-ECoG. Come join us at Duke! coganlab.org/postdoc24@dukebrain.bsky.social
