What Use Are College Rankings?

We’d be better off without college rankings

Until U.S. News & World Report came out with its first rankings of colleges and universities in 1983, few Americans obsessed over the perceived prestige of the school they attended. Some universities were rather vaguely regarded as superior because they were more selective among applicants and had some famous professors on the faculty, but there was nothing like the frenzy to get into one of them that we see today.

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.

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.

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
