Check out our new tool, openEyeTrack, a low-cost open-source high-speed eye tracker for tracking eye position in head-fixed applications. This was a summer project for a talented undergraduate in the lab, Jorge Paolo Casas. We were able to architect a multi-threaded eye tracker using OpenCV, Teledyne DALSA Camera, and C++. We are currently running behavioral […]

If you are interested in arbitrating between DDMs, urgency gating or collapsing boundary models to describe the behavior of observers in perceptual decision-making tasks, then check out our paper (ChaRTr paper) and accompanying toolbox (https://github.com/mailchand/CHaRTr).
We have had a reasonably productive and successful September. Karen Marmon joined the lab. She comes to us from Salzmann lab and will be a research tech with us and lab manager for Jerry Chen. Kenji Lee joined us as a graduate student. He comes from the Allen Institute and brings a lot of experience! […]
Our first paper from the new lab – Audiovisual detection at various intensities and delays has been accepted into Journal of Mathematical Psychology Chandrasekaran C, Gondan MG, Audiovisual detection at different intensities and delays, under revision for Journal of Mathematical Psychology, see biorxiv preprint (link). In this paper, we modeled the accuracy (i.e., hit rate) […]
If you are like me and obsessed about understanding the reaction times and choice behavior of monkeys performing cognitive tasks, then check out our new toolbox, CHaRTr, which has the ability to use a wide range of decision-making models to describe behavior. The biorxiv paper is here and the toolbox is available here :)
Matt golub, a collaborator of mine from Stanford will be presenting our work titled “Joint neural-behavioral models of perceptual decision making”. Matt has worked on a new framework to train RNNs to model both the neural data and behavior simultaneously. He will be presenting this work at COSYNE.
Our new study “Macaque dorsal premotor cortex exhibits decision-related activity only when specific stimulus-response associations are known” has been accepted for publications at Nature Communications. Please see an earlier version of this manuscript on biorxiv (link). The actual published article is now available on the Nature Communications Website (Link to the paper)
My new paper on beta band activity in dorsal premotor cortex coauthored with Iliana Bray and Krishna Shenoy is now available! See link
We have now reworked our webpages. Almost all of our content is live and more is coming soon!
Our new lab is almost ready! We are hiring and super excited to embark on our research :)!!
