<p><strong>Neuronal timescales are functionally dynamic and shaped by cortical microarchitecture.</strong></p>
<p>In this project, we developed a method for measuring neuronal timescales from neural field potential data via <a href="https://github.com/fooof-tools/fooof">spectral parameterization</a>, and apply it to invasive ECoG data from humans and macaques. We find a gradient of neuronal timescales that increase from sensory/motor towards association brain regions, and further combine several other brain-wide structural, gene expression, and behavioral datasets to dissect the physiological factors that underly variations in timescale across the brain, as well as its change during behavior and aging.</p>
