The CIMeC Colloquia Series is an annual set of invited talks given by leading researchers in the mind/brain sciences, both from Italy and abroad, aimed principally at our PhD Students. Given the multi-disciplinary backgrounds of the CIMeC students and researchers, the Colloquia are aimed at a general scientific level rather than at a more specialized audience.
JUNE 6, 2019 04:00 p.m. - Palazzo Fedrigotti, I floor, Conference Room, Corso Bettini 31, Rovereto.
SPEAKER: Matteo Carandini - Professor – University College London
TITLE: Local and global neural correlates of vision and action
ABSTRACT: Behavior arises from neuronal activity patterns, but it is not known whether the relevant neurons are concentrated in a few brain regions or distributed across many regions. We trained mice to report perceptual decisions about visual stimuli, and used high-density Neuropixels arrays to record from >30,000 individual neurons across 42 brain regions in the cerebral cortex, basal ganglia, hippocampus, thalamus, and midbrain. Task-relevant visual and auditory signals propagated through a wide set of brain regions, much wider than expected from passive sensory stimulation. Furthermore, neurons in nearly all brain regions responded around the time of action. Neurons encoding choice prior to action were observed in few regions, with the earliest signals seen in midbrain. These results demonstrate that task-related signals related to sensory processing and motor actions are widely distributed in the brain, and suggest a simple model for how the brain decides between alternatives.
