Subcortical influences on the topology of cortical networks align with functional processing hierarchies

NeuroImage, 2023
fMRI of the human brain reveals spatiotemporal patterns of functional connectivity (FC), forming distinct cortical networks. Lately, subcortical contributions to these configurations are receiving renewed interest, but investigations rarely focus ...

Automated parcellation and atlasing of the human subcortex with ultra-high resolution quantitative MRI. [PDF]

Imaging Neurosci (Camb)
Brain mapping efforts are time-consuming and benefit from an incremental approach. This allows periodic updates with newly acquired data, analysis methods, and resulting atlases and automated delineation approaches.

Multi-study fMRI outlooks on subcortical BOLD responses in the stop-signal paradigm

eLife
This study investigates the functional network underlying response inhibition in the human brain, particularly the role of the basal ganglia in successful action cancellation.

Underlying mechanism of subcortical brain protection during hypoxia and reoxygenation in a sheep model - Influence of α1-adrenergic signalling. [PDF]

PLoS ONE, 2018
While the cerebral autoregulation sufficiently protects subcortical brain regions during hypoxia or asphyxia, the cerebral cortex is not as adequately protected, which suggests that regulation of the cerebral blood flow (CBF) is area-specific.

A probabilistic atlas of the basal ganglia using 7 T MRI

Data in Brief, 2015
A common localization procedure in functional imaging studies includes the overlay of statistical parametric functional magnetic resonance imaging (fMRI) maps or coordinates with neuroanatomical atlases in standard space, e.g., MNI-space.

Hippocampal structural alterations in early-stage psychosis: Specificity and relationship to clinical outcomes

NeuroImage: Clinical, 2022
Hippocampal dysfunctions are a core feature of schizophrenia, but conflicting evidence exists whether volumetric and morphological changes are present in early-stage psychosis and to what extent these deficits are related to clinical trajectories.

Visual attention lies within subcortex [PDF]

British Journal of Ophthalmology, 2002
New research from Germany shows that the subcortex of the brain affects selective visual attention. The discovery comes from a study by Fimm et al of 15 patients (10 with bleeding: five right sided and five left and five with infarction: three right and two left) …

Astrocytes may play a role in the etiology of absence epilepsy: A comparison between immature GAERS not yet expressing seizures and adults

Neurobiology of Disease, 2007
Neuronal–astrocytic interactions in 1-month-old Genetic Absence Epilepsy Rats from Strasbourg (GAERS) before the occurrence of seizures are compared to those in non-epileptic rats (NERs) and in adult GAERS expressing epilepsy.

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

A case of pericapillary arteriovenous malformation

Interdisciplinary Neurosurgery, 2021
Background: Pericapillary arteriovenous malformation (pAVM) frequently causes intracerebral hemorrhage (ICH). However, definitive diagnosis of pAVM is difficult, as it manifests angiographically as cerebral venous malformations.
