Biases in facial and vocal emotion recognition in chronic schizophrenia
Frontiers in Psychology, 2014 There has been extensive research on impaired emotion recognition in schizophrenia in the facial and vocal modalities. The literature points to biases toward non-relevant emotions for emotional faces but few studies have examined biases in emotional ...

On the Origin of Tremor in Parkinson's Disease [PDF]
(2012) PLoS ONE 7(7): e41598, 2012 The exact origin of tremor in Parkinson's disease remains unknown. We explain why the existing data converge on the basal ganglia-thalamo-cortical loop as a tremor generator and consider a conductance-based model of subthalamo-pallidal circuits embedded into a simplified representation of the basal ganglia-thalamo-cortical circuit to investigate the ...

Brain tissue properties differentiate between motor and limbic basal ganglia circuits [PDF]
, 2014 Despite advances in understanding basic organizational principles of the human basal ganglia, accurate in vivo assessment of their anatomical properties is essential to improve early diagnosis in disorders with corticosubcortical pathology and optimize ...

Involvement of the cortico-basal ganglia-thalamocortical loop in developmental stuttering [PDF]
, 2019 Stuttering is a complex neurodevelopmental disorder that has to date eluded a clear explication of its pathophysiological bases. In this review, we utilize the Directions Into Velocities of Articulators (DIVA) neurocomputational modeling framework to ...

A biologically constrained model of the whole basal ganglia addressing the paradoxes of connections and selection [PDF]
Journal of Computational Neuroscience, Springer Verlag (Germany),
2014, 36 (3), pp.445-468, 2015 The basal ganglia nuclei form a complex network of nuclei often assumed to perform selection, yet their individual roles and how they influence each other is still largely unclear. In particular, the ties between the external and internal parts of the globus pallidus are paradoxical, as anatomical data suggest a potent inhibitory projection between ...

Potential mechanisms for imperfect synchronization in parkinsonian basal ganglia [PDF]
, 2012 Neural activity in the brain of parkinsonian patients is characterized by the intermittently synchronized oscillatory dynamics. This imperfect synchronization, observed in the beta frequency band, is believed to be related to the hypokinetic motor ...

Biomimetic race model of the loop between the superior colliculus and the basal ganglia: Subcortical selection of saccade targets [PDF]
Neural Networks, Elsevier, 2015, 67, pp.54-73, 2015 The Superior Colliculus, a laminar structure involved in the retinotopic mapping of the visual field, plays a cardinal role in the several cortical and subcortical loops of the saccadic system. Although the selection of saccade targets has long been thought to be the sole product of cortical processes, a growing body of evidence hints at the ...

Neurobiology of Disease, 2021 L-DOPA-induced dyskinesia (LID) is a significant complication of dopamine replacement therapy in Parkinson's disease (PD), and the specific role of different dopamine receptors in this disorder is poorly understood.
