More Than Just Static: Dynamic Functional Connectivity Changes of the Thalamic Nuclei to Cortex in Parkinson's Disease With Freezing of Gait

Frontiers in Neurology, 2021
Background: The thalamus is not only a key relay node of the thalamocortical circuit but also a hub in the regulation of gait. Previous studies of resting-state functional magnetic resonance imaging (fMRI) have shown static functional connectivity (FC ...

Subcortical Hubs of Brain Networks Sustaining Human Consciousness. [PDF]

Hum Brain Mapp
To inform the next generation of neuromodulatory targets for promoting recovery in patients with disorders of consciousness, we mapped the subcortical connectivity of six canonical networks and identified hub regions of high network integration.

Mouse thalamic differentiation: Gli-dependent pattern and Gli-independent prepattern

Frontiers in Neuroscience, 2012
Sonic hedgehog (Shh) is essential for ventral neural tube development. The Gli transcription factors act downstream Shh—while Gli2 is the major activator (GliA), Gli3 acts primarily as a repressor (GliR).

The intralaminar thalamus – an expressway linking visual stimuli to circuits determining agency and action selection

Frontiers in Behavioral Neuroscience, 2014
Anatomical investigations have revealed connections between the intralaminar thalamic nuclei and areas such as the superior colliculus that receive short latency input from visual and auditory primary sensory areas.

Mapping thalamic-anterior cingulate monosynaptic inputs in adult mice

Molecular Pain, 2022
The anterior cingulate cortex (ACC) is located in the frontal part of the cingulate cortex, and plays important roles in pain perception and emotion. The thalamocortical pathway is the major sensory input to the ACC.

Where Actions Meet Outcomes: Medial Prefrontal Cortex, Central Thalamus, and the Basal Ganglia

Frontiers in Behavioral Neuroscience, 2022
Medial prefrontal cortex (mPFC) interacts with distributed networks that give rise to goal-directed behavior through afferent and efferent connections with multiple thalamic nuclei and recurrent basal ganglia-thalamocortical circuits. Recent studies have

Connectivity-based parcellation of the thalamus explains specific cognitive and behavioural symptoms in patients with bilateral thalamic infarct [PDF]

, 2013
A novel approach based on diffusion tractography was used here to characterise the cortico-thalamic connectivity in two patients, both presenting with an isolated bilateral infarct in the thalamus, but exhibiting partially different cognitive and ...

Characterization of Hippocampal-Thalamic-Cortical Morphometric Reorganization in Temporal Lobe Epilepsy

Frontiers in Neurology, 2022
IntroductionBrain cortico-subcortical connectivity has been investigated in epilepsy using the functional MRI (MRI). Although structural images cannot demonstrate dynamic changes, they provide higher spatial resolution, which allows exploration of the ...

Re-examination of the thalamostriatal projections in the rat with retrograde tracers [PDF]

, 2002
Topographical arrangements of thalamostriatal projection neurons was examined in the rat by the retrograde tract-tracing method. After injecting Fluoro-Gold (FG) and/or cholera toxin beta-subunit (CTB) in different regions of the caudate-putamen (CPu ...

Thalamic inputs to dorsomedial striatum are involved in inhibitory control: evidence from the five-choice serial reaction time task in rats [PDF]

, 2017
Rationale Corticostriatal circuits are widely implicated in the top-down control of attention including inhibitory control and behavioural flexibility. However, recent neurophysiological evidence also suggests a role for thalamic inputs to striatum in
