Exploring healthy infant brain development

The Howell Lab is a group of Virginia Tech scientists working at the Fralin Biomedical Research Institute in Roanoke, VA. We are dedicated to improving mother-infant health outcomes for our community by exploring the factors that influence healthy infant brain and behavioral development. We help families in our community through scientific research and provide a welcoming environment for our research participants.

What kind of tests do we do?

We perform a variety of assessments, while focusing on provide a welcoming, safe environment for all of our research participants. All of our research methods are non-invasive, and help our researchers understand and define characteristics that influence healthy infant brain development. Known factors that are important to healthy neurodevelopment include feeding and sleep habits, nutrition, stress levels, and social interactions.

Participant visits may include:

  • Brain scanning

  • Fun and games (behavioral testing)

  • Surveys for mom

  • Collection of infant stool samples

  • Collection of breast milk samples

What to expect during your study visit:

Current Study: Impact of Nutrition and Experience on Infant Neurodevelopment

We at the MIND Lab want to gain a better understanding of characteristics that influence healthy brain development. In order to do that we will collect several different types of data from both mom and baby across two years. We collect this data by remotely observing interactions between mom and baby (via Zoom), surveys about mom and baby’s health, environment, and past experiences, analyzing infant stool samples, analyzing breast milk samples, and non-invasive infant brain imaging.

Current Study: Analyzing the Effects of COVID-19 on Pregnant Women and New Mothers

Scientists at the MIND Lab are asking pregnant women and moms who have given birth within the last six months to provide input about their experiences amid the COVID-19 pandemic. The 20-25 minute questionnaire will ask study participants to answer questions about their experiences, thoughts, and feelings related to the pandemic. Participants will also complete a brief personality survey and a short task to help us learn how pregnant women and new moms value the future in the context of COVID-19.
