Thrilled about our latest paper published in eLife where we found something cool: A representation of your partner's goals and actions modulates your own "intelligent reflexes", prior to voluntary movement. Led by the phenomenal, Seth Sullivan. elifesciences.org/reviewed-p…

Brain-wide representations of prior information in mouse decision-making: nature.com/articles/s41586-0…

Brain-wide representations of prior information in mouse decision-making

Nature - Brain-wide recordings in mice reveal that prior expectations are distributed through recurrent loops across all levels of cortical and subcortical processing.

A very cool new finding from our lab! During a cooperative sensorimotor task, we show that involuntary visuomotor feedback responses reflect a representation of a partner. biorxiv.org/content/10.1101/… Led by the extremely talented, @SethSullivan_

Involuntary feedback responses reflect a representation of partner actions

We have a remarkable ability to seamlessly and rapidly coordinate actions with others, from double dutch to dancing. Humans use high-level partner representations to jointly control voluntary...

We are excited to share our new paper that dives into how ongoing decision deliberation reflects ongoing movements: (jneurosci.org/content/45/31/…)/ A tour-de-force by the incredible @Jan_Calalo

Finally, we were also able to provide an alternative interpretation of previous reaching behaviour in the literature by using our decision-making and movement model.

bioRxiv has a dedicated section for negative results. Use it. Share negative results. Your colleagues will appreciate it.

Neural space has very similar issues to the behavioural models in the 1990s (e.g., dimensionality reduction, dynamical systems theory/attractors), which are more observational than mechanistic.

Attractors are usually not mechanisms.

Just finished our 3rd annual BRAIN Day for the grade 5 kids at West Park Place Elementary! Big thanks to Truc Ngo for organizing, as well as @HuRoLab, Jenn Semrau, Darcy Reisman, Jill Higginson, and all their great PhD students for making the day a success! #UDBME #UDPT #UDKAAP

Indecisions are extremely common and can lead to catastrophic outcomes. Here we asked what gives rise to indecisive behaviour: journals.physiology.org/doi/… A really nice set of experiments and modelling by the talented @SethSullivan_

Indecisive behavior can be catastrophic, leading to car crashes or stock market losses. Despite fruitful efforts across several decades to understand decision making, there has been little research...
