Twenty years of stem cells

In 1998, UW–Madison developmental biologist James Thomson introduced the world to the first laboratory-derived human embryonic stem cells. Twenty years later, UW–Madison remains at the forefront of stem cell research. The Waisman Center at UW–Madison is a hub of stem cell research, especially in the fields of human development, developmental disabilities and neurodegerative disorders. You …

Blockages in nerve-cell protein ‘factory’ implicated in neurodegenerative disease

Research by Waisman affiliate Jon Audhya shows new insight into the molecular basis underlying the neurodegenerative condition, hereditary spastic paraplegia (HPS). His recent study shows how a mutation in the TFG gene–one of several linked to HPS–impairs neurons from forming structures needed to transmit signals properly.

Mental health in pregnancy may affect development of newborns’ brains

By Marianne Spoon, UW Communications Many factors can influence the development of a baby during pregnancy and after birth, but until recently, researchers knew little about the relationship between an expectant mother’s mental health and the subsequent development of her baby after birth. Findings from a University of Wisconsin–Madison team published Monday, Aug. 27, in …

Ben Parrell, PhD – Slide of the Week

When we speak, we are able to use what we hear about that speech (auditory feedback) to alter our speech movements both in real time within a single word (feedback control) as well as over longer time scales across multiple utterances (feedforward control).

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.

Expecting to learn: Language acquisition in toddlers improved by predictable situations

In an upcoming study in Current Biology, published online Aug. 16, researchers at the Arizona State University Department of Psychology and the Waisman Center report a factor that is important for language learning in children: the predictability of the learning environment.

Caroline A Niziolek, PhD – Slide of the Week

Disorders of speech production may be accompanied by abnormal processing of speech sensory feedback. Here, we introduce a semi-automated analysis designed to assess the degree to which speakers use natural online feedback to decrease acoustic variability in spoken words.

Xinyu Zhao, PhD – Slide of the Week

Adult neural stem cells in mouse models of fragile X syndrome (FXS) have elevated histone acetylation, leading to reduced neurogenesis. Treatment with either Nutlin-3 or Curcumin rebalances histone acetylation and rescues cognitive functions

Houri K. Vorperian, PhD – Slide of the Week

A single-word identification test was used to study speech production in children and adults with Down syndrome (DS) to determine the developmental pattern of speech intelligibility with an emphasis on vowels.

Xinyu Zhao receives 2018 National Fragile X Foundation (NFXF) Research Award

Xinyu Zhao, PhD, received the 2018 National Fragile X Foundation (NFXF) Research Award for outstanding contributions to the understanding of fragile X syndrome. Zhao is a professor of neuroscience and Waisman Center investigator at the University of Wisconsin-Madison.
