This study investigates how rare rewards affect performance and neural activity in rhesus monkeys during a color change detection task, finding detrimental changes in V4 population activity linked to perceptual choking.

The paper uses dual hemisphere recordings and a novel statistical method to show shared neuronal variability across prefrontal cortex populations linked to arousal.

The paper shows that neuronal activity in primary somatosensory cortex changes with experience to support adaptive behavior during sensory learning.
