Behavioral expression of decision confidence engages disentangled confidence coding in the orbitofrontal cortex Open
Task engagement is thought to recruit subsets of neurons encoding task-relevant variables, but it remains unclear whether it also reorganizes the geometry of population codes and how such reorganization supports behavior. Here we show that…

A neural circuit targeting technique for investigating functional input-output organization in the nervous system Open
Neurons communicate information across circuits and the function of cells in these circuits is determined by both the afferent inputs they receive and the efferent outputs they send to other brain regions 1,2 . To study the activity and fu…

Auditory Cortex Neurons Show Task-Related and Learning-Dependent Selectivity toward Sensory Input and Reward during the Learning Process of an Associative Memory Task Open
The activity of primary auditory cortex (A1) neurons is modulated not only by sensory inputs but also by other task-related variables in associative learning. However, it is unclear how A1 neural activity changes dynamically in response to…

Hippocampal CA1 Neurons Represent Positive Feedback During the Learning Process of an Associative Memory Task Open
The hippocampus is crucial for forming associations between environmental stimuli. However, it is unclear how neural activities of hippocampal neurons dynamically change during the learning process. To address this question, we developed a…

Over-representation of fundamental decision variables in the prefrontal cortex underlies decision bias Open
The brain is organized into anatomically distinct structures consisting of a variety of projection neurons. While such evolutionarily conserved neural circuit organization underlies the innate ability of animals to swiftly adapt to environ…

Contribution of non-sensory neurons in visual cortical areas to visually guided decisions in the rat Open
It is widely assumed that trial-by-trial variability in visual detection performance is explained by the fidelity of visual responses in visual cortical areas influenced by fluctuations of internal states, such as vigilance and behavioral …

Visually-evoked choice behavior driven by distinct population computations with non-sensory neurons in visual cortical areas Open
It is widely assumed that variability in visual detection performance is attributed to the fidelity of the visual responses in visual cortical areas, which could be modulated by fluctuations of internal states such as vigilance and behavio…

Dynamic coordination of the perirhinal cortical neurons supports coherent representations between task epochs Open
Cortical neurons show distinct firing patterns across multiple task-epochs characterized by distinct computational aspects. Recent studies suggest that such distinct patterns underly dynamic population code achieving computational flexibil…
