Neural Mechanisms of Auditory Behaviors: from trained behaviors to naturalistic vocal communication

We have been tackling a challenge in auditory neuroscience: bridging a gap between our understanding of primate auditory behaviors and their neural mechanisms. Previous work focused on neural mechanisms of task-trained auditory behaviors, auditory categorization and perceptual decision-making (Tsunada et al., 2011, 2012, 2016, 2019). We recently started and keep studying naturalistic auditory behavior, vocal communication (Eliades and Tsunada, 2018, Tsunada and Eliades, 2020).
