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

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

DARPA-backed brain-computer interface just published in Nat. Electronics: Ken and colleagues present a fully implanted, 50-μm thick ECoG with 65.000 channels on a 256x256 grid. Their system wirelessly transmits power and signals to a relay-coil outside the skull

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

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
#neuroskyence
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

A race to the brain 🧠
Paradromics has just received FDA IDE approval to implant their micro-electrode array in human participants. The neuralink competitor will soon start recruiting patients with speech/motor impairments at UC Davis, Mass General Hospital and U Michigan

New article in Nature showing that the superior temporal gyrus (STG) encodes language-specific features stronger when listening to the native language. Bilinguals on the other hand shared this higher-level tuning across both of their familiar languages

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...

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.
KI-Gehirn-Chip bei Querschnittlähmung: Was bringt ein in das Gehirn implantierter Chip Menschen mit Querschnittlähmung mehr an Lebensqualität und Mobilität?
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)...

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...
The human superior temporal gyrus processes acoustic–phonetic properties of speech regardless of whether the language is familiar to the listener, but only encodes word boundaries and language-sp...

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...
The LGN is a critical stage between the retina and visual cortex, but the properties of human LGN neurons are not fully understood. Here the authors report that they closely resemble those in monkeys ...
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...
