Neuroimaging of septo-optic dysplasia-plus with midbrain hypoplasia and ophthalmoplegia

eNeurologicalSci, 2020
Septo-optic dysplasia is a rare brain malformation that can be associated with anomalous cortical development, such as schizencephaly, which is referred to as septo-optic dysplasia plus.

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Anatomical functional changes in a patient presenting a complex malformation of cortical development.

, 2004
The authors describe a case of right fronto-parietal micropoligyria associated with small schizencephaly clefts and the presence of a frontal open-lip schizencephaly with corpus callosum agenesis.

Material Coupling in Hybrid Neuromorphic Devices: From Fundamentals to System‐Level Applications

Advanced Functional Materials, EarlyView.
Hybrid neuromorphic devices utilize heterointerfaces between emerging semiconductors, where charge transfer and trapping, ion or defect modulation, and photogating are translated into synaptic functions. This paper discusses coupling strategies that tailor interfacial electronic and ionic properties in organic semiconductors, metal oxides, two ...

Tubulin genes and malformations of cortical development [PDF]

European Journal of Medical Genetics, 2018
A large number of genes encoding for tubulin proteins are expressed in the developing brain. Each is subject to specific spatial and temporal expression patterns. However, most are highly expressed in post-mitotic neurons during stages of neuronal migration and differentiation.

Focal Cortical Dysplasia Type IIB and Human Papillomavirus

Pediatric Neurology Briefs, 2013
Researchers at Temple University School of Medicine, Philadelphia, PA tested the hypothesis that human papillomavirus type 16 oncoprotein E6 (HPV16 E6) is present in human focal cortical dysplasia type IIB (FCDIIB) specimens.

Cerebral activation in malformations of cortical development [PDF]

Brain, 1998
Malformations of cortical development (MCD) are an important aetiology of localization-related epilepsy. Previous MRI and [11C]flumazenil PET studies have demonstrated widespread structural and neuroreceptor abnormalities beyond the region of MCD that is visually apparent on MRI.

Magnetoactive Hydrogels to Probe Curvature‐Directed Endothelial Cell Mechanosensing

Advanced Healthcare Materials, EarlyView.
This work establishes a platform to investigate local curvature as a regulator of endothelial mechanosensing independent of shear stress. Magnetoactive hydrogels enable on‐demand curvature of endothelial monolayers to reproduce tortuosity quantified by clinically established metrics.
