Westmont Researchers Use High-Tech Tool to Study Neurological Disorders

As part of a summer research project, Yi-Fan Lu, Westmont assistant professor of biology, and senior Heidi Pullmann used the new microelectrode array, purchased through the Westmont Provost’s Office, to detect and record the response of neurons to genetic mutation or toxins.

Westmont’s academic program gives students opportunities to work directly with faculty on research and scholarly projects.

Pullmann and 22 other students will present their findings at the Celebration of Summer Research, 3:30 p.m. Friday, Sept. 21, in Westmont’s Winter Hall Atrium.

Lu will offer live demonstrations with the MED64 Presto, Monitor Neuronal Activities in Real Time: A Novel Tool for Modeling Neurological Disorders and Drug Discovery, at 4 and 4:30 p.m. in Winter Hall, room 331, in the psychology wing.

“The microelectrode array can also be used to screen for new drugs, examining if any compounds have reversed the effect of the mutation or the toxin to the neurons,” Lu said.

“This equipment has the power to push neurological disorder research to the next level in 20 years and potentially discover new drugs for many diseases that currently have no cure,” Lu said.

Lu and Kristi Cantrell, associate professor of chemistry at Westmont, are collaborating with colleagues at UCSB to examine peptides that may lead to Alzheimer’s disease.

This summer, Lu worked with Pullmann, a Westmont senior biology major from Florence, SC, testing four shorter tau peptide variants.

“I hope this research will lead to the advancement of the understanding of Alzheimer’s and other neurodegenerative diseases,” Pullman said.

“The project that we are working on is part of a much larger study into the mechanisms of the disease, and I would love to contribute to the knowledge of the scientific community,” he said. “Scientific advancement typically happens in small increments, but I hope that what we are doing is an important one.”

After graduating in May, Pullmann is interested in attending graduate school to study agricultural and plant sciences.

“I am interested in developing better ways to grow plants through plant genetics or agricultural technologies, and in aiding in discoveries that can help end world hunger,” she said.

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
