Selective visual representation of letters and words in the left ventral occipito-temporal cortex with intracerebral recordings.

Proc Natl Acad Sci U S A 2018 08 23;115(32):E7595-E7604. Epub 2018 Jul 23.

Psychological Sciences Research Institute, UCLouvain, B-1348 Louvain-La-Neuve, Belgium.

We report a comprehensive cartography of selective responses to visual letters and words in the human ventral occipito-temporal cortex (VOTC) with direct neural recordings, clarifying key aspects of the neural basis of reading. Intracerebral recordings were performed in a large group of patients ( = 37) presented with visual words inserted periodically in rapid sequences of pseudofonts, nonwords, or pseudowords, enabling classification of responses at three levels of word processing: letter, prelexical, and lexical. While letter-selective responses are found in much of the VOTC, with a higher proportion in left posterior regions, prelexical/lexical responses are confined to the middle and anterior sections of the left fusiform gyrus.

Automated Detection of Convulsive Seizures Using a Wearable Accelerometer Device.

IEEE Trans Biomed Eng 2018 Jun 11. Epub 2018 Jun 11.

Epileptic seizure detection requires specialized approaches such as video/electroencephalography monitoring. However, these approaches are restricted mainly to hospital setting and requires video/EEG analysis by experts, which makes these approaches resource- and labor-intensive. In contrast, we aim to develop a wireless remote monitoring system based on a single wrist-worn accelerometer device, which is sensitive to multiple types of convulsive seizures and is capable of detecting seizures with short duration.

Atypical Presentation of a Progressive and Treatable Encephalopathy in an Older Child With Gelastic and Dacrystic Seizures.

Semin Pediatr Neurol 2018 07 23;26:95-100. Epub 2017 May 23.

From the Pediatric Neurology Division, Nationwide Children's Hospital, The Ohio State University, Columbus, OH.

We discuss an unusual case of a teenage boy who presented with waxing and waning cognitive decline and gelastic-dacrystic seizures, evolving later into a rapidly progressive encephalopathy with status epilepticus. Extensive genetic and metabolic testing did not lead to a specific diagnosis. Cerebrospinal fluid studies performed during admission to the intensive care unit provided the information needed to establish a diagnosis. Read More
