Low Rates of Pointing in 18-Month-Olds at Risk for Autism Spectrum Disorder and Extremely Preterm Infants: A Common Index of Language Delay?

Frontiers in Psychology, 2019
Infants with an older sibling with an Autism Spectrum Disorder diagnosis (Sibs ASD) are at high risk for language delay (LD) as well as infants born preterm, especially those with an extremely low gestational age (ELGA, GA ≤ 28 weeks).

Engineering Pareidolia: Mental Imagery, Perceptual Scaffolding, and Visual Creativity

Brain Sciences
Pareidolia is often framed as a viewer-side illusion: a tendency to perceive meaningful forms—especially faces—in ambiguous inputs. This Concept Paper argues that pareidolia can also be deliberately engineered and therefore provides a tractable entry ...

Real-Time Surface EMG Pattern Recognition for Hand Gestures Based on an Artificial Neural Network

Italian National Conference on Sensors, 2019
In recent years, surface electromyography (sEMG) signals have been increasingly used in pattern recognition and rehabilitation. In this paper, a real-time hand gesture recognition model using sEMG is proposed.

Neurosyphilis and limbic encephalitis: practical guidance for diagnosis and treatment sequencing at an infection–autoimmunity interface

Frontiers in Neurology
Syphilis remains a re-emerging global infection with protean neurologic manifestations. Although neurosyphilis has long been framed as a direct infectious involvement of the central nervous system, an emerging case-based literature suggests that, in ...
