Demonstration of the ability of MPnRAGE to correct for severe motion artifacts in a 7 year old girl. Retrospective motion correction greatly reduced motion-induced blurring in both structural T1-weighted images and quantitative T1 maps. The correction greatly improves the reliability of brain imaging measurements in children. The plots indicate the estimated amount of head motions that were corrected.
Brain Imaging
Doug Dean, III, PhD – Slide of the Week
White matter microstructure, essential for efficient and coordinated transmission of neural communications, undergoes pronounced development during the first years of life, while deviations to this neurodevelopmental trajectory likely result in alterations of brain connectivity relevant to behavior. Hence, systematic evaluation of white matter microstructure in the normative brain is critical for a neuroscientific approach to both typical and atypical early behavioral development.
Fraction Understanding in 8th Graders
The Educational Neuroscience Lab and Mathematics Education Learning & Development Lab are working with the Waisman Center to investigate the development of fraction knowledge in children. Knowledge of fractions and mathematical competence are important determinants …
Brain Imaging Study for Adults with Down Syndrome
The Waisman Center is seeking adults with Down syndrome, ages 30 and above, for a research study involving an MRI and a PET scan to examine amyloid plaque in the brains of these individuals. Researcher …
Neuroimaging in FXS and ASD
The Waisman Center at the University of Wisconsin-Madison is recruiting boys with fragile X syndrome and autism spectrum disorder for a study on language and communication skills and Magnetic Resonance Imaging (MRI). Boys should be …
Pediatric Brain Care Study
The Pediatric Brain Care Study is recruiting typically developing children, 9-17 years old, with no history of head injury for a brain imaging research study. Those who participate will have a MRI brain scanning and …
The Effects of Video Game Learning on the Brain in Adolescents with Autism
The Motor and Brain Development Lab at the Waisman Center is recruiting high-functioning adolescents with Autism Spectrum Disorder (14-17 years old) from the Madison, WI area for a research study that looks at brain and …
Researchers unveil new strategy to correct for motion during MRI scans
Individuals undergoing a magnetic resonance imaging (MRI) scan often need to minimize movements for up to 10 minutes at a time to maximize scan quality. That can be challenging for many people.

Empathy, the ability to understand others’ emotions, can occur through perspective taking and experience sharing. Neural systems active when adults empathize include regions underlying perspective taking (e.g. medial prefrontal cortex; MPFC), and experience sharing (e.g. inferior parietal lobule; IPL).

Alzheimer’s disease is characterized by accumulation of beta amyloid (Aβ) and hyperphosphorylated tau proteins, which neuropathology suggests follow distinct spatiotemporal patterns.
