Dynamic Neuronal Representation in the Prefrontal Cortex
The present paper investigated the neural mechanisms underlying dynamic neural representation in the prefrontal cortex (PFC), which is thought to play a crucial role in flexible cognitive behavior. Neural representation is discrete or continuous according to the information to be encoded. The multistable attractor model is a plausible theory of flexible control of representation. Attractor stat...
متن کاملHierarchical error representation in medial prefrontal cortex
The medial prefrontal cortex (mPFC) is reliably activated by both performance and prediction errors. Error signals have typically been treated as a scalar, and it is unknown to what extent multiple error signals may co-exist within mPFC. Previous studies have shown that lateral frontal cortex (LFC) is arranged in a hierarchy of abstraction, such that more abstract concepts and rules are represe...
متن کاملPrefrontal cortex function in the representation of temporally complex events.
The frontal cortex and inferior temporal cortex are strongly functionally interconnected. Previous experiments on prefrontal function in monkeys have shown that a disconnection of prefrontal cortex from inferior temporal cortex impairs a variety of complex visual learning tasks but leaves simple concurrent object-reward association learning intact. We investigated the possibility that temporal ...
متن کاملRepresentation of Multiple, Independent Categories in the Primate Prefrontal Cortex
Neural correlates of visual categories have been previously identified in the prefrontal cortex (PFC). However, whether individual neurons can represent multiple categories is unknown. Varying degrees of generalization versus specialization of neurons in the PFC have been theorized. We recorded from lateral PFC neural activity while monkeys switched between two different and independent categor...
متن کاملCategorical representation of visual stimuli in the primate prefrontal cortex.
The ability to group stimuli into meaningful categories is a fundamental cognitive process. To explore its neural basis, we trained monkeys to categorize computer-generated stimuli as "cats" and "dogs." A morphing system was used to systematically vary stimulus shape and precisely define the category boundary. Neural activity in the lateral prefrontal cortex reflected the category of visual sti...
