Medial Pulvinar Nucleus as a Causal Hub for Heteromodal Naming Our ability to retrieve the names of objects in our environment is a fundamental aspect of everyday life. This process requires a complex, dynamic network of cortical and subcortical interactions. Whi...

Out now in #JNeurosci! We used direct recordings and stimulation in human pulvinar to probe its causal role during naming from pictures, and spoken and written descriptions. We found naming-selective responses and stim-induced pure anomia.

We measured brain stimulation evoked potentials (BSEPs) to evaluate how network dynamics change after a brief trial of DBS during #iEEG. The effects were not immediate, and only after DBS was delivered for >1.5 hours, we observed that BSEP amplitude was reduced compared to baseline.

Today is the day!
So excited for this moment.

Brain Dynamics of Mental Manipulation Humans effortlessly juggle their internal thoughts, but the neuronal dynamics that support mental manipulation are largely unknown. Leveraging the high spatiotemporal fidelity of intracranial recordin...

What happens in the brain when we manipulate our thoughts?

We asked 30 epilepsy patients to mentally invert short melodies.

Intracerebral #iEEG recordings suggest brain synchrony and sensory inhibition are key for mental manipulation:

this looks great! (+ cool plots)

given that alpha rhythm is often decreased in frequency (e.g. 8 Hz instead of 10 Hz) for epileptic patients and this is #iEEG data, I find it tricky to call this theta-activity; but it's also different from classical mu-dynamics (Fig. S4). 🤔

Transfer learning via distributed brain recordings enables reliable speech decoding - Nature Communications Speech brain-computer interfaces face challenges scaling across individuals with different brain organization. Using minimally invasive recordings from 25 patients, the authors developed transfer learning methods that enable robust speech decoding even with incomplete brain coverage.
