Excited to share a soft launch of our latest work! We show that oscillatory gamma bursts in the auditory cortex organize spike-timing precision, rather than firing rate, to selectively enhance sounds coming from behaviorally relevant locations.

Neurons don't just fire more for important sounds, their activity becomes more precisely timed and rhythmic

Are brain rhythms a steady hum or a brief buzz? Both. Alpha and beta activity are relatively sustained, helping maintain ongoing brain state, supporting its role in top-down control.

The locus coeruleus, which provides norepinephrine to the rest of the brain, is even more spatially and functionally diverse than previously thought, new findings suggest.

Anatomy sets things up, but it’s not the whole story. A low-D communication subspace from PFC to motor cortex reconfigures with context, routing action signals so the same movements can be driven by different rules without rewiring the whole network.

Cortical circuits are often thought to be specialized, but the same large-scale activity patterns can arise from different circuit architectures. In other words, different instruments can play the same tune, and the same instrument can sometimes play different tunes.

Thrilled that my paper is out in the @nature.com. We explored how the brain builds complex tasks by compositionally combining simpler sub-task representations. The brain flexibly performs multiple tasks by dynamically reusing neural subspaces for sensory inputs and motor actions

When you record spikes, you also record LFPs. It’s ironic to hear people claim oscillations don’t matter while they are discarding the very data that could test that. As Thomas Kuhn would say…
