Long-term unsupervised recalibration of cursor-based intracortical brain–computer interfaces using a hidden Markov model - Nature Biomedical Engineering A hidden Markov model that uses probabilistic retrospective inference allows for up to one month of unsupervised recalibration in an online cursor-based intracortical brain–machine interface.

Frequent BCI recalibration due to changing neural activity mark a significant hurdle in long-term BCI engagement. Researchers at stanford now demonstrate a clever approach enabling unsupervised decoder adaptation by infering task labels and reinforcing the neural decoder

Selective engagement of the primate orbitofrontal cortex during value-based but not perceptual decisions A fundamental question in neuroscience is whether the brain uses specialized sub-systems for different types of decisions or relies on a unified decision-making network. The orbitofrontal cortex (OFC)...

New study challenges the idea of a unified decision network: Neuropixel recordings in primate OFC showed robust encoding during value-based choices but near-silence during perceptual decisions, even when rewards are at stake. #RewardSignals #neuroskyence www.biorxiv.org/content/10.1...

Towards decoding individual words from non-invasive brain recordings - Nature Communications While deep learning has enabled the decoding of language from intracranial brain recordings, achieving this with non-invasive recordings remains an open challenge. Here the authors introduce a deep le...

Speech decoding on the basis of single words has so far been limited to intracranial recordings. Scientists demonstrated the feasibility of non-invasive language decoding using EEG and MEG, finding that more training data consistently increases model performance

Non-invasive ultrasonic neuromodulation of the human nucleus accumbens impacts reward sensitivity - Nature Communications This study shows that non-invasive ultrasound to the human nucleus accumbens can modulate deep brain activity and enhance reward-guided learning, offering a potential alternative to invasive neuromodu...

Changing behavior with ultrasound 🔊🧠

Focused ultrasound is shown to reliably modulate deep brain areas such as the nucleus accumbens, comparable to DBS. Stimulation during a reinforcement learning task altered reward expectation, learning curves and task strategy

Insular error network enables self-correcting intracranial brain-computer interface Error recognition is fundamental to adaptive behavior, enabling rapid compensatory action when outcomes deviate from expectations. Central to this function are neural circuits for performance monitori...

Insular neural interfaces

Cognitive error signals in the anterior insula propagate toward prefrontal cortex when a BCI fails to follow the user’s intention. Real-time integration enables a self-correcting neural interface that compensates for its own decoder misclassifications

Thalamus for vision BCIs

Scientists have recorded single neurons in the human LGN for the first time, revealing how it links the retina to visual cortex. When one eye is closed, neurons tuned to that eye reduce their activity, while neurons tuned to the open eye increase in spikerate

Human superior temporal gyrus (STG) encodes the progression of a word as it unfolds in time. The neural activity tracks relative position within the word, regardless of its length, and resets at each new word boundary.
