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

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

Spiking activity near intracortical stimulation sites proved to accurately predict the brightness and sharpness of perception. Using these signals in real time could one day optimize the individualized experience of each phosphene

The company behind the stentrode just raised $200M in Series D funding, led by Double point ventures, Bezos Expeditions and ARCH ventures. The funding will be used to develop smaller stentrodes reaching multiple brain regions 🧠

Researchers demonstrated that stimulation of the thalamus helped reduce seizures by over 80%. Their approach showed a reduction in epileptiform discharges, in line with the nuclei's critical role in seizure termination

A recent study used transfer learning on distributed iEEG recordings to enhance speech decoding. By learning shared latent manifolds, their cross-subject model outperformed individual models in a speech motor task.

ICMS affects both vascular and immune responses. Higher currents increase blood-brain barrier leakage, letting substances enter surrounding tissue. Soon after, microglia activate and cluster around highly active regions

Scientists mapped the precise nerve circuits causing dangerous spikes in mice, rats, and humans. By stimulating these circuits with epidural electrical stimulation, they activated a competing pathway that stabilized blood pressure.
