Diversity of cortical activity changes beyond depression during spreading depolarizations

A Nasretdinov, D Vinokurova, CL Lemale… - Nature …, 2023 - nature.com
Spreading depolarizations (SDs) are classically thought to be associated with spreading
depression of cortical activity. Here, we found that SDs in patients with subarachnoid …

Intracranial voltage profiles from untangled human deep sources reveal multisource composition and source allocation bias

J Makarova, R Toledano, L Blázquez-Llorca… - Journal of …, 2025 - jneurosci.org
Intracranial potentials are used as functional biomarkers of neural networks. As potentials
spread away from the source populations, they become mixed in the recordings. In humans …
