Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

The upside of epilepsy: Theories of an evolutionary paradox

Epilepsia Open, EarlyView.
Abstract The persistence of common, heritable conditions, like epilepsy, that are associated with reduced reproductive fitness is an evolutionary paradox. Endogenous analgesic, anti‐depressant, and inflammatory mechanisms able to repair compromised functions can offer advantages in unexpected crises.

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

Revista Chilena de Radiología
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.

Methodological aspects of analyzing high resolved brain connectivity for multiple subjects

Current Directions in Biomedical Engineering, 2017
Analyzing directed interactions within brain networks of high spatial resolution is always associated with a limited interpretability due to the high amount of possible connections.

Abnormalities of thalamus and thalamocortical pathways in patients with refractory epilepsy caused by focal cortical dysplasia – MRI study

Epilepsia Open, EarlyView.
Abstract Objective Drug‐resistant epilepsy, a severe and diagnostically challenging neurological condition often linked to focal cortical dysplasia (FCD), represents a significant social and healthcare burden. While the thalamus is notably altered in this disorder, it remains unclear whether these changes result from epilepsy manifestation or ...

Seeing in the dark: High-order visual functions under scotopic conditions

iScience
Summary: It is unknown how and to what degree people function visually in almost complete darkness, where only rod photoreceptors are active (scotopic conditions). To explore this, we first tested scotopic acuity and crowding.

Prefrontal Cortex Recruitment to Food Stimuli Differs in Overweight/Obesity and Binge Eating Disorder

European Eating Disorders Review, EarlyView.
ABSTRACT Background At a phenotypical level, the repeated occurrence of binge eating episodes clearly differentiates individuals with binge eating disorder (BED) from individuals with overweight but without BED. Their neural profiles during food‐related inhibition, however, indicate prefrontal hypoactivation in both groups.
