We observed an anomaly in the human electroencephalogram (EEG) associated with exposure to terrestrial trunked radio (TETRA) Radiofrequency Fields (RF). Here, we characterize the time and frequency components of the anomaly and demonstrate that it is an artefact caused by TETRA RF interfering with the EEG recording equipment and not by any direct or indirect effect on the brain.

Event-related brain potentials (ERPs) were recorded from 13 scalp electrodes while subjects read sentences containing syntactic ambiguities. Words which were inconsistent with the "preferred" sentence structure elicited a brain potential (P600) quite distinct from the potential previously observed following contextually inappropriate words (N400). Furthermore, final words in sentences typically...

PURPOSE: To describe the imaging features of a brain anomaly found on studies of three patients, and to speculate on the embryologic basis leading to the development of this abnormality. PATIENTS AND METHODS: Clinical records (three patients) , MR scans (two patients). and CT scans (two patients) of three patients with fusion of the middle portions of the cerebral hemispheres in the presence of...

With the advent of deep learning and increasing use brain MRIs, a great amount interest has arisen in automated anomaly segmentation to improve clinical workflows; however, it is time-consuming expensive curate medical imaging. Moreover, data are often scattered across many institutions, with privacy regulations hampering its use. Here we present FedDis collaboratively train an unsupervised con...

BACKGROUND: Computer-aided diagnosis (CAD) systems have been the focus of several research endeavors and it based on the idea of processing and analyzing images of different hemorrhage of the brain for a quick and accurate diagnosis. This paper proposed for automated brain anomaly segmentation are developed and applied to a large dataset of brain PD, T1and T2-weighted MR images.

Cerebral cavernous malformations are commonly associated with a developmental venous anomaly. Sparing this anomaly is considered important as it frequently is part of the venous drainage of normal brain parenchyma. We present a case in which a developmental venous anomaly of the third ventricle associated with a thalamic cavernous malformation increased the degree of difficulty of successful en...

We describe a case of body stalk anomaly which was diagnosed at 10 weeks of gestation on a dating scan. The fetus was visualized within the exocelomic cavity outside an apparently intact amniotic membrane. The fetus displayed multiple anomalies characteristic of body stalk syndrome including a skull and brain defect, abdominal wall defect, kyphoscoliosis and gross deformities of the lower limbs...

BACKGROUND AND PURPOSE Developmental venous anomalies are considered variants of venous development that, in and of themselves, are of little clinical import. A possible association between intrinsic brain tumors and developmental venous anomalies has been suggested, but a rigorous investigation has not been performed. The aim of this study was to assess any association between developmental ve...

Morning glory syndrome (MGS), an uncommon optic disc anomaly, is characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. Generally, it is an isolated ocular abnormality. The authors describe two patients in whom MGS developed in association with brain abnormalities. In both cases, there was enlargement of the optic nerve that showed increased r...
