Rational thoughts in neural codes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Complex behaviors are often driven by an internal model, which integrates sensory information over time and facilitates long-term planning to reach subjective goals. A fundamental challenge in neuroscience is, How can we use behavior and neural activity to understand this internal model and its dynamic latent variables?

Challenges to the Vestibular System in Space: How the Brain Responds and Adapts to Microgravity

open access: yesFrontiers in Neural Circuits, 2021
In the next century, flying civilians to space or humans to Mars will no longer be a subject of science fiction. The altered gravitational environment experienced during space flight, as well as that experienced following landing, results in impaired ...

Indices for Testing Neural Codes [PDF]

open access: yesNeural Computation, 2008
One of the most critical challenges in systems neuroscience is determining the neural code. A principled framework for addressing this can be found in information theory. With this approach, one can determine whether a proposed code can account for the stimulus-response relationship.

Internal State Dependent Odor Processing and Perception—The Role of Neuromodulation in the Fly Olfactory System

open access: yesFrontiers in Cellular Neuroscience, 2018
Animals rely heavily on their sense of olfaction to perform various vital interactions with an ever-in-flux environment. The turbulent and combinatorial nature of air-borne odorant cues demands the employment of various coding strategies, which allow the

Outcome contingency selectively affects the neural coding of outcomes but not of tasks [PDF]

open access: yes, 2019
Value-based decision-making is ubiquitous in every-day life, and critically depends on the contingency between choices and their outcomes. Only if outcomes are contingent on our choices can we make meaningful value-based decisions.

An inhibitory gate for state transition in cortex

open access: yeseLife, 2017
Large scale transitions between active (up) and silent (down) states during quiet wakefulness or NREM sleep regulate fundamental cortical functions and are known to involve both excitatory and inhibitory cells.

Characterization of multiscale logic operations in the neural circuits

open access: yesFrontiers in Bioscience-Landmark, 2021
Background: Ever since the seminal work by McCulloch and Pitts, the theory of neural computation and its philosophical foundation known as ‘computationalism’ have been central to brain-inspired artificial intelligence (AI) technologies. The present study

Learning Task-Related Activities From Independent Local-Field-Potential Components Across Motor Cortex Layers

open access: yesFrontiers in Neuroscience, 2018
Motor cortical microcircuits receive inputs from dispersed cortical and subcortical regions in behaving animals. However, how these inputs contribute to learning and execution of voluntary sequential motor behaviors remains elusive. Here, we analyzed the

A general decoding strategy explains the relationship between behavior and correlated variability

open access: yeseLife, 2022
Improvements in perception are frequently accompanied by decreases in correlated variability in sensory cortex. This relationship is puzzling because overall changes in correlated variability should minimally affect optimal information coding.
