Brain‐wide magnetic resonance imaging analysis of neurobehavioral comorbidities in temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective In temporal lobe epilepsy (TLE), patients often present with neurobehavioral comorbidities encompassing affective and cognitive difficulties. Whereas the latter have been related to atypical connectivity of mesiotemporal and frontotemporal circuits, the brain basis of affective symptoms remains incompletely understood.

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

Epilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Grundlagen und Mechanismen der Neocortex-Expansion.

, 2020
During primate, and notably human, evolution, the neocortex increased massively in size. This increase forms the basis of our higher cognitive abilities in comparison to other mammals.

Kv3.1 activation suppresses provoked and spontaneous seizures in a mouse Dravet syndrome model

Epilepsia, EarlyView.
Abstract Objective γ‐Aminobutyric acidergic (GABAergic) parvalbumin‐positive (PV+) interneurons are critical for maintaining cortical inhibitory tone, with their dysfunction predictably leading to epilepsy. Rapid PV+ interneuron firing is essential for their normal function and is maintained in part by potassium voltage‐gated channels.

Why is the right side of the brain responsible for the left side of the body? The evolutionary history of a puzzling trait

Frontiers in Neuroanatomy
In humans, the right motor cortex controls the spinal motoneurons that cause the limbs on the left sides of our bodies to move. Similarly, the right side of the cerebral cortex predominantly receives sensory information about the left side of our bodies ...

An adaptive threshold in mammalian neocortical evolution.

PLoS Biology, 2014
Expansion of the neocortex is a hallmark of human evolution. However, determining which adaptive mechanisms facilitated its expansion remains an open question.

Limited sex‐specific structural alterations across common epilepsies: A worldwide ENIGMA study

Epilepsia, EarlyView.
Abstract Objective Epilepsy is characterized by widespread cortical and subcortical structural alterations beyond the epileptic zone. Importantly, the clinical manifestation of epilepsy, including seizure types, psychiatric comorbidities, and treatment responses, has been shown to differ between sexes. However, sex differences in structural alterations

Transcriptomic analysis reveals distinct expression patterns in focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a common cause of drug‐resistant epilepsy in children and adults and exhibits substantial clinical and histopathological heterogeneity. However, morphological classification alone does not fully explain variability in epileptogenicity, disease severity, or treatment response.

Spike detection in the wild: Screening of suspected temporal lobe epilepsy cases using a tailored 2‐channel wearable EEG

Epilepsia Open, EarlyView.
Abstract Objective To clinically validate the contribution of a custom‐built EEG wearable device (waEEG) compared to a full 10–20 electrode array ambulatory EEG (aEEG) for screening epilepsy cases in patients with suspected temporal lobe epilepsy (TLE) but negative routine EEGs. Methods Patients (aged 16–91 years) with clinically suspected TLE who were

Timing is everything: The effect of early‐life seizures on developing neuronal circuits subserving spatial memory

Epilepsia Open, EarlyView.
Abstract Spatial memory, the aspect of memory involving encoding and retrieval of information regarding one's environment and spatial orientation, is a complex biological function incorporating multiple neuronal networks. Hippocampus‐dependent spatial memory is not innate and emerges during development in both humans and rodents.
