Amplitude of low‐frequency fluctuation of resting‐state fMRI in primary nocturnal enuresis and attention deficit hyperactivity disorder
Sign Up to like & getrecommendations! Published in 2020 at "International Journal of Developmental Neuroscience"
DOI: 10.1002/jdn.10020
Abstract: Children with attention deficit hyperactivity disorder (ADHD) and nocturnal enuresis (NE) have similar symptoms, for example, inattention and dysfunction of working memory. We investigate disorder‐specific abnormal activity by using the simple resting‐state functional magnetic resonance… read more here.

DOI: 10.1097/wnr.0000000000002145
Abstract: Autistic traits exist on a continuum within the general population, yet how these traits influence regional neural activity during real-world social interactions remains unclear. Using functional near-infrared spectroscopy (fNIRS), we investigated how autistic traits relate… read more here.
