Pupil Dynamics Reflect Behavioral Choice and Learning in a Go/NoGo Tactile Decision-Making Task in Mice

Abstract: The eye’s pupil undergoes dynamic changes in diameter associated with cognitive effort, motor activity and emotional state, and can be used to index brain state across mammalian species. Recent studies in head-fixed mice have linked arousal-related pupil dynamics with global neural activity as well as the activity of specific neuronal populations. However, it has remained unclear how pupil dynamics in mice report trial-by-trial performance of behavioral tasks, and change on a longer time scale with learning. W… Show more

“…To determine the effect of S1-or M1-corticostriatal input on sensorimotor behavior, we assessed how optogenetic stimulation of these regionally specific corticostriatal inputs affected performance of a whisker-dependent texture discrimination task in head-fixed mice ( Figure 3A-C ) [54,56,59] . In this Go/NoGo task, mice receive water reward for correct licking in response to the rough texture (Hit trial) and no water reward for licking in response to the smooth texture (False Alarm trial).…”

“…Following the implant surgery, mice were allowed to recover for an additional week prior to handling. A custom head post was fitted to each mouse using methods similar to those previously described [54,56,59,81] . Briefly, mice were anesthetized with isoflurane (4% induction, 0.8-1.5% maintenance) and mounted onto a stereotaxic frame (Stoelting) with a feedback controlled heating blanket maintained at 36℃ (FHC) on the base.…”

“…In the current experiments, we examined how the pupil response elicited by cues during learning was linked to changes in error‐driven attention predicted by the Pearce‐Hall theory. Across a wide range of experimental paradigms, pupil size has been previously reported to be linked not only to learning (Eldar, Cohen, & Niv, ; Kahneman & Peavler, ; Lee & Margolis, ; Nassar et al, ; Reinhard & Lachnit, ; Reinhard, Lachnit, & Koenig, ) and memory (Brocher & Graf, ; Naber, Fraessle, Ruitshäuser, & Einhäuser, ; van Rijn, Dalenberg, Borst, & Sprenger, ), but also to attentional orienting (Corneil & Munoz, ; Geva, Zivan, Warsha, & Olchik, ; Lynn, ; Sokolov, ; Wang & Munoz, ) and the processing of uncertainty and error (Jepma & Nieuwenhuis, ; Nassar et al, ; O'Reilly et al, ; Preuschoff, t' Hart, & Einhäuser, ; Richer & Beatty, ; Satterthwaite et al, ). In extension of these previous findings, the current article examines how changes in pupil size during learning correspond to changes in error and error‐driven attention.…”

“…In the current study we show that when in a state of engagement, defined as task responsiveness, large dilations are observed following stimulation, with larger dilations for correct than error responses ( Fig 3A). However, this difference might be reward driven (Lee and Margolis, 2016).…”
