Guided by Noise: Correlated Variability Channels Task-Relevant Information in Sensory Neurons

The paper shows that shared variability in sensory neurons aligns with task-relevant features and action plans, and that this alignment enhances behaviorally relevant information.

Orthogonal neural representations support perceptual judgements of natural stimuli

The paper shows that orthogonal neural representations in V4 allow stable perception of object position despite irrelevant background features in natural scenes.

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

The paper shows that perceptual performance and correlated variability in sensory cortex are inversely related due to observers using a general decoding strategy rather than optimal stimulus-specific decoding.

Methylphenidate as a causal test of translational and basic neural coding hypotheses

This study uses methylphenidate to test neural coding hypotheses and uncover its effects on visual attention and neuronal variability in rhesus macaques.

Topological insights into the neural basis of flexible behavior

This paper uses topological data analysis to link neural activity, cognitive processes, and behavior by showing how topological changes in neural populations relate to task performance and model discrimination.

Learning And Attention Reveal A General Relationship Between Neuronal Variability And Perception

The paper shows that neuronal variability correlates with perceptual performance in visual tasks, suggesting shared mechanisms between attention and learning.
