Neuromodulation of prefrontal cortex cognitive function in primates: the powerful roles of monoamines and acetylcholine
The primate prefrontal cortex (PFC) subserves our highest order cognitive operations, and
yet is tremendously dependent on a precise neurochemical environment for proper …

Cortical hierarchy, dual counterstream architecture and the importance of top-down generative networks
Hierarchy is a major organizational principle of the cortex and underscores modern
computational theories of cortical function. The local microcircuit amplifies long-distance …

Hierarchical action encoding in prefrontal cortex of freely moving macaques
Our natural behavioral repertoires include coordinated actions of characteristic types. To
better understand how neural activity relates to the expression of actions and action …

Abstract task representations for inference and control
Behavioral flexibility depends on our capacity to build and leverage abstract knowledge
about tasks. Recently, two separate lines of research have implicated distinct brain networks …

Representations of common event structure in medial temporal lobe and frontoparietal cortex support efficient inference
Prior work has shown that the brain represents memories within a cognitive map that
supports inference about connections between individual related events. Real-world …

The prefrontal cortex: from monkey to man
R Levy - Brain, 2024 - academic.oup.com
The prefrontal cortex is so important to human beings that, if deprived of it, our behaviour is
reduced to action-reactions and automatisms, with no ability to make deliberate decisions …

Neural representation of abstract task structure during generalization
Cognitive models in psychology and neuroscience widely assume that the human brain
maintains an abstract representation of tasks. This assumption is fundamental to theories …

Policy abstraction as a predictor of cognitive effort avoidance.
Consistent evidence has established that people avoid cognitively effortful tasks. However,
the features that make a task cognitively effortful are still not well understood. Multiple …

Echolocation-related reversal of information flow in a cortical vocalization network
The mammalian frontal and auditory cortices are important for vocal behavior. Here, using
local-field potential recordings, we demonstrate that the timing and spatial patterns of …
