+# Summary
+![](./figures/overview.jpg)
+
+**Neuronal timescales are functionally dynamic and shaped by cortical microarchitecture.**
+
+In this project, we developed a method for measuring neuronal timescales from neural field potential data via [spectral parameterization][napp], 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.

+# Data
+This project uses several open datasets, thanks to the generosity and foresight of those that compile and share their data. See Table 1 in the paper for a list of all datasets used.

+
+---
+# Code
+`./echo_utils.py` contains all the python helper functions used for subsequent analyses and visualizations.
+
+`./scripts/` contains analysis scripts that compute and parameterize the PSDs in each ECoG database.
+
+`./data/` contains intermediate data tables and diagnostic plots.
+
+`./notebook/` contains Jupyter notebook that explains the project and paper in its entirety, and produces the figures seen in the publication. See Table 2 in the paper for the notebook-figure correspondence.

+Surface projection of T1w/T2w and gene expression data is done using Rudy's repository [here][surface_proj].
