Dopaminergic contributions to vocal learning

LA Hoffmann, V Saravanan, AN Wood… - Journal of …, 2016 - Soc Neuroscience
Although the brain relies on auditory information to calibrate vocal behavior, the neural
substrates of vocal learning remain unclear. Here we demonstrate that lesions of the …

Songbird: a unique animal model for studying the molecular basis of disorders of vocal development and communication

C Mori, K Wada - Experimental animals, 2015 - jstage.jst.go.jp
Like humans, songbirds are one of the few animal groups that learn vocalization. Vocal
learning requires coordination of auditory input and vocal output using auditory feedback to …

Cingulate and cerebellar beta oscillations are engaged in the acquisition of auditory‐motor sequences

M Herrojo Ruiz, B Maess, E Altenmüller… - Human Brain …, 2017 - Wiley Online Library
Singing, music performance, and speech rely on the retrieval of complex sounds, which are
generated by the corresponding actions and are organized into sequences. It is crucial in …

Altering attention to split-belt walking increases the generalization of motor memories across walking contexts

DM Mariscal, PA Iturralde… - Journal of …, 2020 - journals.physiology.org
Little is known about the impact of attention during motor adaptation tasks on how
movements adapted in one context generalize to another. We investigated this by …

Adaptation to pitch-altered feedback is independent of one's own voice pitch sensitivity

R Alemi, A Lehmann, MLD Deroche - Scientific reports, 2020 - nature.com
Monitoring voice pitch is a fine-tuned process in daily conversations as conveying accurately
the linguistic and affective cues in a given utterance depends on the precise control of …

Dopamine depletion affects vocal acoustics and disrupts sensorimotor adaptation in songbirds

V Saravanan, LA Hoffmann, AL Jacob, GJ Berman… - ENeuro, 2019 - eneuro.org
Dopamine is hypothesized to convey error information in reinforcement learning tasks with
explicit appetitive or aversive cues. However, during motor skill learning feedback signals …

Predicting plasticity: acute context-dependent changes to vocal performance predict long-term age-dependent changes

LS James, JT Sakata - Journal of neurophysiology, 2015 - journals.physiology.org
Understanding the factors that predict and guide variation in behavioral change can lend
insight into mechanisms of motor plasticity and individual differences in behavior. The …

Chance, long tails, and inference in a non-Gaussian, Bayesian theory of vocal learning in songbirds

B Zhou, D Hofmann, I Pinkoviezky… - Proceedings of the …, 2018 - National Acad Sciences
Traditional theories of sensorimotor learning posit that animals use sensory error signals to
find the optimal motor command in the face of Gaussian sensory and motor noise. However …

Developmental modulation and predictability of age-dependent vocal plasticity in adult zebra finches

LS James, JT Sakata - Brain Research, 2019 - Elsevier
Predicting the nature of behavioral plasticity can provide insight into mechanisms of
behavioral expression and control. Songbirds like the zebra finch rely on vocal signals for …

Sensorimotor control of vocal production in early childhood.

NE Scheerer, DS Jacobson… - Journal of Experimental …, 2020 - psycnet.apa.org
