Aberrant prefrontal activity and arousal level correlate with action initiation and response vigor

Frederike J. Klein, Dmitrii Vasilev, Ryo Iwai, Masataka Watanabe, Nelson K. B. Totah

The paper links prefrontal cortex activity to response vigor and arousal in rats performing a Go/NoGo task.

Volitional stopping is preceded by a transient beta oscillation

Joana F. Doutel Figueira, Reetta A. Ojala, Dmitrii Vasilev, Alejandro De Miguel, Lucas Jeay-Bizot, Ryo Iwai, Isabel Raposo, Negar Safaei, Lilian de Sardenberg Schmid, Uri Maoz, Masataka Watanabe, Nelson K. B. Totah

This study shows that beta oscillations in the motor cortex precede stopping in rats, but have limited utility for real-time decoding.

Brightness illusions evoke pupil constriction and a preceding primary visual cortex response in rats

Dmitrii Vasilev, Isabel Raposo, Nelson K. B. Totah

This study shows that a brightness illusion that causes pupil constriction in humans also does so in rats, with V1 cortex activity preceding the pupil response.

Focusing perceptual attention in the past constrains outcome-based learning in the future by adjusting cortico-cortical interactions

Dmitrii Vasilev, Negar Safaei, Ryo Iwai, Hessam Bahmani, Ioannis S. Zouridis, Masataka Watanabe, Nikos K. Logothetis, Nelson K. B. Totah

The paper shows that perceptual attention in one sensory modality affects subsequent outcome-based learning in another modality by altering cortico-cortical interactions in rats.

Three water restriction schedules used in rodent behavioral tasks transiently impair growth and differentially evoke a stress hormone response without causing dehydration

Dmitrii Vasilev, Daniel Havel, Simone Liebscher, Silvia Slesiona-Kuenzel, Nikos K. Logothetis, Katja Schenke-Layland, Nelson K. B. Totah

This study examines the effects of three water restriction schedules on rodent growth, hydration, and stress hormone levels over 80 days, finding no dehydration but differential stress responses.
