Analysis of higher-order coincident activity in multiple parallel processes [PDF]

open access: yes, 2002
The synchronization of neuronal firing activity is considered an important mechanism in cortical information processing. The tendency of multiple neurons to synchronize their joint firing activity can be investigated with the 'unitary event' analysis ...

What happens in between? Human oscillatory brain activity related to crossmodal spatial cueing. [PDF]

open access: yes, 2008
Previous studies investigated the effects of crossmodal spatial attention by comparing the responses to validly versus invalidly cued target stimuli. Dynamics of cortical rhythms in the time interval between cue and target might contribute to cue effects

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.

Neural masses and fields: modeling the dynamics of brain activity. [PDF]

open access: yes, 2013
This technical note introduces a conductance-based neural field model that combines biologically realistic synaptic dynamics—based on transmembrane currents—with neural field equations, describing the propagation of spikes over the cortical surface. This

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Paramagnetic Rim Lesions and Choroid Plexus Volume at Diagnosis Are Associated With Cognitive Progression Independent of Relapse and MRI Activity in Early Relapsing–Remitting Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Paramagnetic rim lesions (PRLs) and choroid plexus (CP) enlargement reflect smoldering inflammation in multiple sclerosis. Their role in cognitive progression remains unexplored. Eighty‐seven early relapsing–remitting MS patients were enrolled at diagnosis and followed longitudinally.

Role of Robo1 receptor in semaphorin signalling system and cortical interneuron migration [PDF]

open access: yes, 2010
En route to the cerebral cortex, interneurons encounter the developing striatum and avoid it. It has been shown that these cells express neuropilin (Nrp) as well as PlexinA receptors, which allow these cells to respond to Sema3A and Sema3F ...

Thalamo‐Lesional Connectivity Signatures of Bilateral Tonic–Clonic Seizures in Focal Cortical Dysplasia‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

OBTENCION DE MAPAS CORTICALES DE AREAS MOTORA Y VISUAL, CON RESONANCIA MAGNETICA CEREBRAL FUNCIONAL

open access: yesRevista Chilena de Radiología, 2006
La resonancia magnética funcional (RMF) es una técnica no invasiva que permite medir los cambios relacionados con flujo sanguíneo cerebral regional. Se efectuó un mapeo de la corteza sensitivo-motora y de la corteza visual en 24 voluntarios sanos.
