The external pallidum: think locally, act globally [PDF]
arXiv, 2021 The globus pallidus (GPe) of the basal ganglia has been underappreciated for decades due to poor understanding of its cells and circuits. The advent of molecular tools has sparked a resurgence in interest in the GPe. Here, we review a recent flurry of publications that has unveiled the complexity of the molecular landscape and cellular composition ...

Frontiers in Computational Neuroscience, 2013 Many computational models of the basal ganglia have been proposed over the past twenty-five years. While computational neuroscience models have focused on closely matching the neurobiology of the basal ganglia, computational cognitive neuroscience models

The causal interaction in human basal ganglia
Scientific Reports, 2021 The experimental study of the human brain has important restrictions, particularly in the case of basal ganglia, subcortical centers whose activity can be recorded with fMRI methods but cannot be directly modified.

How Laminar Frontal Cortex and Basal Ganglia Circuits Interact to Control Planned and Reactive Saccades [PDF]
, 2000 The basal ganglia and frontal cortex together allow animals to learn adaptive responses that acquire rewards when prepotent reflexive responses are insufficient.

Bidirectional Control of Absence Seizures by the Basal Ganglia: A Computational Evidence [PDF]
, 2014 Absence epilepsy is believed to be associated with the abnormal interactions between the cerebral cortex and thalamus. Besides the direct coupling, anatomical evidence indicates that the cerebral cortex and thalamus also communicate indirectly through an important intermediate bridge--basal ganglia.

Volumetric segmentation of multiple basal ganglia structures [PDF]
, 2009 We present a new active contour-based, statistical method for simultaneous volumetric segmentation of multiple subcortical structures in the brain. Neighboring anatomical structures in the human brain exhibit co-dependencies which can aid in segmentation,

Basal ganglia role in learning rewarded actions and executing previously learned choices: Healthy and diseased states [PDF]
, 2020 The basal ganglia (BG) is a collection of nuclei located deep beneath the cerebral cortex that is involved in learning and selection of rewarded actions. Here, we analyzed BG mechanisms that enable these functions.

, 2020 AbstractThe basal ganglia include the striatum (caudate, putamen, and ventral striatum) which receive from all cortical areas, and which project via the globus pallidus and substantia nigra back to the neocortex. The basal ganglia are implicated in stimulus-response habit learning, which may be provided by a reinforcement learning signal received by ...

Thalamic interaction between the input and the output systems of the basal ganglia [PDF]
, 1999 The striatal return through the thalamus is largely neglected in current studies dealing with basal ganglia function, and its role within this circuitry remains obscure.

Who dominates who in the dark basements of the brain? [PDF]
, 2007 Subcortical substrates for behavioural integration include the fore/midbrain nuclei of the basal ganglia and the hindbrain medial reticular formation. The midbrain superior colliculus requires basal ganglia disinhibition in order to generate orienting ...
