A biologically detailed computational model is described of how categorization judgments become automatic in tasks that depend on procedural learning. The model assumes 2 neural pathways from sensory association cortex to the premotor area that mediates response selection. A longer and slower path projects to the premotor area via the striatum, globus pallidus, and thalamus. A faster, purely cortical path projects directly to the premotor area. The model assumes that the subcortical path has… 

Multiple stages of learning in perceptual categorization: evidence and neurocomputational theory

A new, neurobiologically detailed model of procedural category learning is proposed, which synthesizes evidence of multiple distinct cortical-striatal loops into a neurocomputational theory and is incompatible with existing S-R models.

A new neurocomputational model of automaticity in rule-guided behavior is proposed, which assumes two parallel neural pathways corresponding to “naïve” and “expert” rule use and includes differential equations that describes voltage changes in the relevant brain areas and difference equations that describe the Hebbian learning.

Evidence for Cortical Automaticity in Rule-Based Categorization

The results of an experiment in which human participants each practiced a rule-based categorization task for >10,000 trials distributed over 20 separate sessions suggest an initial subcortical neural system centered around the head of the caudate that is gradually replaced by a cortical systemcentered around the ventrolateral prefrontal cortex.

Neurocomputational models of corticostriatal interactions in action selection

A general overview of findings related to frontostriatal circuits is given, focusing on neurological, neuropsychological, neurobiological, and neurophysiological features, which should help constrain in both neural and psychological term.

Abstract relational categories, graded persistence, and prefrontal cortical representation

A theory of prefrontal cortical function is presented that proposes that neurons in PFC are particularly sensitive to relationship information, and that they develop response preferences for relationship information that increases in abstractness and complexity along the posterior–anterior axis.



The neurobiology of category learning.

Cognitive neuroscience literature on category learning appears contradictory until the results are partitioned according to the type of category-learning task that was used, and results are consistent with the hypotheses that (a) learning in rule-based tasks requires working memory and executive attention and is mediated by frontal-striatal circuits, and (b)learning in information-integration tasks requires procedural memory and ismediated primarily within the basal ganglia.

Comparison of learning‐related neuronal activity in the dorsal premotor cortex and striatum

As monkeys learned conditional visuomotor associations, neurons in the premotor cortex and associated parts of the putamen changed their rates at approximately the same time, confirming the hypothesis that cortex and basal ganglia function in distributed architectures known as cortical–basal ganglionic modules or ‘loops’.


Dissociating explicit and procedural-learning based systems of perceptual category learning

Neural correlates of rule-based and information-integration visual category learning.

Functional neuroimaging was used to assess activity in medial temporal lobe and posterior regions of the caudate systems during category-learning tasks with category structures designed to afford either RB or II learning.

Making Working Memory Work: A Computational Model of Learning in the Prefrontal Cortex and Basal Ganglia

This article presents an attempt to deconstruct this homunculus through powerful learning mechanisms that allow a computational model of the prefrontal cortex to control both itself and other brain areas in a strategic, task-appropriate manner.

FROST: A Distributed Neurocomputational Model of Working Memory Maintenance

A computational model of WM, called FROST, is proposed in which the representation of items and spatial positions is encoded in the lateral prefrontal cortex, and successfully accounts for a wide variety of WM data, including single-cell recording data and human behavioral data.

A Biologically Based Computational Model of Working Memory

This model defines working memory as controlled processing involving active maintenance and/or rapid learning, where controlled processing is an emergent property of the dynamic interactions of multiple brain systems, but the prefrontal cortex and hippocampus are especially influential owing to their specialized processing abilities.

Model of cortical-basal ganglionic processing: encoding the serial order of sensory events.

A modular neural network model of the prefrontal (PF) cortex and basal ganglia that encodes the serial order of events into spatial patterns of PF activity is presented and a method for analyzing serial receptive fields is presented for comparing the model units to single-unit data.

Visual categorization and the primate prefrontal cortex: neurophysiology and behavior.

The training of monkeys to categorize computer-generated stimuli as "cats" and "dogs" suggests that the lateral prefrontal cortex is an important part of the neuronal circuitry underlying category learning and category-based behaviors.
