Topic: Choice bias as a window to the microscopic dynamics of choice

Idiosyncratic tendency to choose one alternative over another in the absence of an identified reason is a common observation in two-alternative forced-choice experiments. I will present experimental and theoretical evidence that even in an idealized experiment, in which the settings are symmetric, idiosyncratic choice bias inevitably emerges from the dynamics of competing neuronal networks. Finally, I will discuss the stability of the bias over months and the implications regarding the stability of synaptic connectivity.
