Individualized closed-loop acoustic stimulation suggests an alpha phase-dependence of sound-evoked and induced brain activity measured with electroencephalogram (EEG) recordings.
SUMMARY. Healthy adult brains generate alpha oscillations and individual subjects have unique alpha oscillation frequencies, which impacts how they dynamically process, ignore, and attend to sensory information. Our study uses a novel closed-loop technology and individualized approach to play sounds at physiologically distinct peak or trough phases of ongoing alpha oscillations. We find sounds played phase-locked to trough versus peak alpha phases measured with electroencephalography (EEG) elicit distinct brain potentials and changes in alpha oscillations. This study supports the feasibility of using a novel individualized, closed-loop, neuromodulation to investigate and potentially improve abnormal alpha and other oscillation activity associated with multiple neurological disorders.

New results! The prefrontal cortex uses a low-dimensional โcoding spaceโ. Info can be captured in just 3โ6 dimensions. The brain compresses what we remember.

After wrapping up an R01 submission, this felt like the perfect Friday neuroscience paper. As a vision scientist, I never get tired of a good illusion. Two simple rotating circles become a 3D cylinder in the mind's eye, revealing how the brain constructs perception from ambiguity

Very cool analysis of the degree to which brain signals can be predicted by backprop signals. One issue though is confounding. Not sure there is a way to correct.

Being a scientist and an engineer, I have to insist that they both actually *are* identities. And if you are either you will feel it. It is not merely that you engineer. You *are* an engineer. You don't merely research. You *are* a scientist. And @ylecun always will be both.
