Utah Electrode Array

 

 

When implanted in the brain, the Utah Electrode Array (UEA) can record action potentials and local field potentials, and be used for micro-stimulation of neural tissue.

Decoding spoken words

Decoding spoken words using local field potentials recorded from the cortical surface

Communication in patients with “locked-in syndrome” is often an arduous task. Intuitive and rapid communication may be restored by directly interfacing with language areas of the cerebral cortex. We used a grid of closely spaced, nonpenetrating micro-electrodes to record local field potentials (LFPs) from the surface of face motor cortex and Wernicke’s area. From these LFPs we successfully classified a small set of words on a trial-by-trial basis at levels well above chance, demonstrating that this approach can be used to potentially restore communication to locked-in patients.

Electrodes detect finger movement

Detection and classification of multiple finger movements using a chronically implanted Utah Electrode Array

This work demonstrates a decoding method that can detect and classify finger movements without any a priori knowledge of the data, task, or behavior, and lend further support that a chronically implanted Utah Electrode Array is suitable for both acquiring and decoding neuronal data. Go to PubMed
