Bilinearity, Rules, and Prefrontal Cortex
Humans can be instructed verbally to perform computationally complex cognitive tasks; their performance then improves relatively slowly over the course of practice. Many skills underlie these abilities; in this paper, we focus on the particular question of a uniform architecture for the instantiation of habitual performance and the storage, recall, and execution of simple rules. Our account bui...
متن کاملPrefrontal cortex and flexible cognitive control: rules without symbols.
Human cognitive control is uniquely flexible and has been shown to depend on prefrontal cortex (PFC). But exactly how the biological mechanisms of the PFC support flexible cognitive control remains a profound mystery. Existing theoretical models have posited powerful task-specific PFC representations, but not how these develop. We show how this can occur when a set of PFC-specific neural mechan...
متن کاملA Comparison of Abstract Rules in the Prefrontal Cortex, Premotor Cortex, Inferior Temporal Cortex, and Striatum
The ability to use abstract rules or principles allows behavior to generalize from specific circumstances. We have previously shown that such rules are encoded in the lateral prefrontal cortex (PFC) and premotor cortex (PMC). Here, we extend these investigations to two other areas directly connected with the PFC and the PMC, the inferior temporal cortex (ITC) and the dorsal striatum (STR). Monk...
متن کاملP142: The Prefrontal Cortex and Stress-Related Psychopathologies
The prefrontal cortex (PFC) plays a central role in processing both normal and pathological affective states and it is among the brain regions most closely associated with stress-related psychopathology in humans. The ventromedial PFC (vmPFC) in particular has been shown to be required for healthy emotional regulation, social function and risk assessment and decision-making. Also this region ex...
متن کاملBasic mathematical rules are encoded by primate prefrontal cortex neurons.
Mathematics is based on highly abstract principles, or rules, of how to structure, process, and evaluate numerical information. If and how mathematical rules can be represented by single neurons, however, has remained elusive. We therefore recorded the activity of individual prefrontal cortex (PFC) neurons in rhesus monkeys required to switch flexibly between "greater than" and "less than" rule...
