ErbB4 regulation of a thalamic reticular nucleus circuit for sensory selection
Sandra Ahrens,Santiago Jaramillo,Santiago Jaramillo,Kai Yu,Sanchari Ghosh,Ga-Ram Hwang,Raehum Paik,Cary Lai,Miao He,Miao He,Z. Josh Huang,Bo Li +11 more
TL;DR: This work shows in mice that deficiency of the Erbb4 gene in somatostatin-expressing TRN neurons markedly alters behaviors that are dependent on sensory selection, and proposes that ErbB4 sets the sensitivity of the TRN to cortical inputs at levels that can support sensory selection while allowing behavioral flexibility.

Stable representation of sounds in the posterior striatum during flexible auditory decisions
TL;DR: This study shows that auditory information is represented by neuronal activity of the posterior tail of the dorsal striatum in mice, and that this brain region mediates rodent’s flexible decision making based on auditory cues.
Response outcomes gate the impact of expectations on perceptual decisions
Ainhoa Hermoso-Mendizabal,Alexandre Hyafil,Alexandre Hyafil,Pavel E. Rueda-Orozco,Santiago Jaramillo,David Robbe,Jaime de la Rocha +6 more
TL;DR: Rats can learn to either alternate or repeat their actions based on reward likelihood and the influence of bias on their actions disappears after making an error, demonstrating that, based on previous outcomes, rats flexibly modulate how expectations influence their decisions.
Auditory Thalamostriatal and Corticostriatal Pathways Convey Complementary Information about Sound Features.
TL;DR: Characterizing the sound-evoked responses of thalamostriatal and corticostriata neurons demonstrates that these neural pathways convey complementary information about the temporal features of sounds, and opens new avenues for investigating how these pathways could be selectively recruited depending on task demands.

Response outcomes gate the impact of expectations on perceptual decisions
Ainhoa Hermoso-Mendizabal,Alexandre Hyafil,Pavel E. Rueda-Orozco,Santiago Jaramillo,David Robbe,Jaime de la Rocha +5 more
TL;DR: It is shown that rats use behavioral outcomes to flexibly modulate how expectations derived from the recent history influence their decisions, as captured by a non-linear generative model of rat behavior.
