Experience shapes activity dynamics and stimulus coding of VIP inhibitory cells

…, K Roll, DR Ollerenshaw, PA Groblewski, ND Ponvert… - elife, 2020 - elifesciences.org
Cortical circuits can flexibly change with experience and learning, but the effects on specific
cell types, including distinct inhibitory types, are not well understood. Here we investigated …

Auditory thalamostriatal and corticostriatal pathways convey complementary information about sound features

ND Ponvert, S Jaramillo - Journal of Neuroscience, 2019 - Soc Neuroscience
Multiple parallel neural pathways link sound-related signals to behavioral responses. For
instance, the striatum, a brain structure involved in action selection and reward-related learning…

[HTML][HTML] Stable representation of sounds in the posterior striatum during flexible auditory decisions

L Guo, WI Walker, ND Ponvert, PL Penix… - Nature …, 2018 - nature.com
The neuronal pathways that link sounds to rewarded actions remain elusive. For instance, it
is unclear whether neurons in the posterior tail of the dorsal striatum (which receive direct …

The role of sensory cortex in behavioral flexibility

L Guo, ND Ponvert, S Jaramillo - Neuroscience, 2017 - Elsevier
To thrive in a changing environment, organisms evolved strategies for rapidly modifying their
behavioral responses to sensory stimuli. In this review, we investigate the role of sensory …
