Previous research on the role of the basal ganglia in category learning has focused on patients with Parkinson's and Huntington's disease, neurodegenerative diseases frequently accompanied by additional cortical pathology. The goal of the present study was to extend this work to patients with basal ganglia lesions due to stroke, asking if similar changes in performance would be observed in patients with more focal pathology. Patients with basal ganglia lesions centered in the putamen (6 left… Expand
Rule-based categorization deficits in focal basal ganglia lesion and Parkinson's disease patients
TLDR
The data suggest that the demands on selective attention and working memory affect the presence of impairment in patients with focal BG lesions and the nature of the impairment in users of dopaminergic medication. Expand
ule-based categorization deficits in focal basal ganglia lesion and Parkinson ’ s isease patients
Patients with basal ganglia (BG) pathology are consistently found to be impaired on rule-based category learning tasks in which learning is thought to depend upon the use of an explicit,Expand
Prefrontal contributions to rule-based and information-integration category learning
TLDR
Examination of rule-based and information-integration category learning in 13 patients with damage primarily to ventral PFC regions provides further evidence that the ventromedial prefrontal cortex is critically important for the ability to monitor and integrate feedback in order to select and maintain optimal learning strategies. Expand
Rule-based and information-integration category learning in normal aging
TLDR
The results suggest that normal aging impacts both forms of category learning and that there are some important similarities and differences in the explanatory locus of these deficits. Expand
The role of the orbitofrontal cortex in human discrimination learning
TLDR
Data support the notion that the orbitofrontal cortex play a role in normal discrimination learning, and suggest qualitative similarities in learning performance of patients with OFC damage and medicated PD patients. Expand
Functional Neuroanatomy and Behavioural Correlates of the Basal Ganglia: Evidence from Lesion Studies
TLDR
It is often difficult to precisely map associations between cognitive, emotional or behavioural functions and particular basal ganglia substructures, due to the non-specific nature of the lesions, but evidence from lesion studies shows that most symptoms correspond with established non-motor frontal-subcortical circuits. Expand
Contributions of the putamen to cognitive function
It is now well accepted that the basal ganglia contribute to cognition. Much of the cognitive functionality of the basal ganglia has been attributed to the striatum in general, and the caudateExpand
Impact of putamen stroke on task context updating: Evidence from P300 brain waves
TLDR
The delayed auditory P300 component in both patient groups but neither control group suggests impairment of memory updating in patients with putamen stroke comparable with thalamic stroke, illustrating the important role of subcortical structures subserved in context updating. Expand
Frontal and Basal Ganglia Contributions to Memory and Attention
Herein I research the role of the basal ganglia and prefrontal cortex in visual working memory and attention by examining patients with focal, unilateral lesions to these brain regions. By combiningExpand
The evaluative role of rostrolateral prefrontal cortex in rule-based category learning
TLDR
The results revealed that rlPFC activation persisted into correct trials in classification, but not matching, suggesting that it continues to be involved in the evaluations of evidence for a rule even after participants have arrived at the correct rule. Expand

Rule-Based Category Learning is Impaired in Patients with Parkinson's Disease but not in Patients with Cerebellar Disorders
TLDR
Model-based analyses indicate that the patients with Parkinson's disease were able to select the appropriate categorization rule, but that they adopted suboptimal category boundaries in both conditions and were more variable in the application of the selected rule. Expand
Characterizing rule-based category learning deficits in patients with Parkinson's disease
TLDR
Parkinson's disease patients and normal controls were tested in three category learning experiments to determine if previously observed rule-based category learning impairments in PD patients were due to deficits in selective attention or working memory, and these findings help to delineate the conditions under which PD patients display rule- based category learning deficits. Expand
Category learning deficits in Parkinson's disease.
TLDR
The hypothesis that learning in these 2 tasks is mediated by functionally separate systems is supported, as patients with Parkinson's disease and older controls were compared in 2 category-learning tasks. Expand
Category learning deficits in Parkinson's disease.
Sixteen patients with Parkinson's disease (PD), 15 older controls (OCs), and 109 younger controls (YCs) were compared in 2 category-learning tasks. Participants attempted to assign colored geometricExpand
Dissociation of Habit-Learning in Parkinson's and Cerebellar Disease
TLDR
The probabilistic learning task is an implicit, nonmotor learning task which is sensitive for basal ganglia pathology but remains unaffected in the case of cerebellar pathology. Expand
Effects of focal basal ganglia lesions on timing and force control
TLDR
The results indicate that unilateral basalganglia lesions tend to produce minor motor problems in force control, and fail to support the hypothesized role of the basal ganglia in timing. Expand
Role of the basal ganglia in category learning: how do patients with Parkinson's disease learn?
TLDR
Examining learning strategies among patients with basal ganglia dysfunction showed that patients with Parkinson's disease exhibit different patterns of strategy use, and most controls adopted a more complex, optimal learning strategy, integrating single-cue associations to predict outcomes for multiple-cue stimuli. Expand
Information-integration category learning in patients with striatal dysfunction.
TLDR
It is suggested that the striatum may be particularly involved in information-integration category learning when the rule is highly complex. Expand
A possible role of the striatum in linear and nonlinear category learning: evidence from patients with Huntington's disease.
TLDR
It is suggested that Huntington's disease can result in a deficit in learning both linear and nonlinear categorization rules. Expand
The role of the striatum in rule application: the model of Huntington's disease at early stage.
TLDR
It is found that early Huntington's disease patients were impaired in rule application in the linguistic and non-linguistic domains (morphology, syntax and subtraction), whereas they were broadly spared with lexical processing, which suggests that the striatum is involved in rule processing more than in lexicalprocessing and that it extends to linguistic andnon-lingUistic domains.
