Publications

These are ~30 papers/preprints I have published over the years on a variety of topics including decision-making, motor control, and multisensory integration. My scholar page has all the numbers you want:. I have also included altmetric badges where available for these papers as a measure of the impact of these studies. As of July 2024, the lab has a h-index of 21, and cited more than 2400 times.

Code and Data

This paper is the published version of a preprint with the same data but less complete analyses as the published Nature Comm. paper.

Additional information
This paper is closely related to three other papers. The paper started out with only PMd data and over time evolved to have data from DLPFC and a new intellectual framework (information bottlenecks developed by Tishby et al.).
