Specialized coding of sensory, motor and cognitive variables in VTA dopamine neurons

…, J Cox, W Fleming, HJ Jang, S Ornelas, SA Koay… - Nature, 2019 - nature.com
There is increased appreciation that dopamine neurons in the midbrain respond not only to
reward 1 and reward-predicting cues 1 , 2 , but also to other variables such as the distance to …

Volumetric two-photon imaging of neurons using stereoscopy (vTwINS)

A Song, AS Charles, SA Koay, JL Gauthier… - Nature …, 2017 - nature.com
Two-photon laser scanning microscopy of calcium dynamics using fluorescent indicators is
a widely used imaging method for large-scale recording of neural activity in vivo. Here, we …

[HTML][HTML] An accumulation-of-evidence task using visual pulses for mice navigating in virtual reality

L Pinto, SA Koay, B Engelhard, AM Yoon… - Frontiers in behavioral …, 2018 - frontiersin.org
The gradual accumulation of sensory evidence is a crucial component of perceptual decision
making, but its neural mechanisms are still poorly understood. Given the wide availability …

Novel stimuli evoke excess activity in the mouse primary visual cortex

J Homann, SA Koay, KS Chen… - Proceedings of the …, 2022 - National Acad Sciences
To explore how neural circuits represent novel versus familiar inputs, we presented mice with
repeated sets of images with novel images sparsely substituted. Using two-photon calcium …

Cerebellar involvement in an evidence-accumulation decision-making task

B Deverett, SA Koay, M Oostland, SSH Wang - elife, 2018 - elifesciences.org
10.7554/eLife.36781.001 To make successful evidence-based decisions, the brain must
rapidly and accurately transform sensory inputs into specific goal-directed behaviors. Most …

[PDF][PDF] Sequential and efficient neural-population coding of complex task information

SA Koay, AS Charles, SY Thiberge, CD Brody… - Neuron, 2022 - cell.com
Recent work has highlighted that many types of variables are represented in each
neocortical area. How can these many neural representations be organized together without …

Amplitude modulations of cortical sensory responses in pulsatile evidence accumulation

SA Koay, S Thiberge, CD Brody, DW Tank - Elife, 2020 - elifesciences.org
How does the brain internally represent a sequence of sensory information that jointly drives
a decision-making behavior? Studies of perceptual decision-making have often assumed …
