Abstract

Comments on the book The Organisation of Mind by T. Shallice and R. P. Cooper (2011). The current authors report that this book provides an integrative view of the neurocognitive underpinnings of higher-level cognition, as gleaned from the cognitive neuroscience approach. It is noted that abundant neuroimaging and neuropsychological data indicate that increasingly rostral subregions of the dorsal prefrontal cortex (PFC) are recruited when task demands become more abstract. PFC subsystems may reflect in part their dissociable patterns of frontostriatal connectivity. Dorsal PFC participates in a set of GPi-mediated corticostriatal loops that preserve rostrocaudal topography and give rise to policy abstraction, operating alongside a more integrative SNr-mediated ventrofronto-striatal circuit for state abstraction. This framework provides a computationally-, neuro- psychologically-, and neuroanatomically-grounded basis for identifying isolable subsystems in higher-level cognition.
