Packapalooza 2019!

Last weekend, Packapalooza drew large crowds despite the rainy weather. Luckily for us, the Sombers Lab was representing the chemistry department under a tent! Our brain models, sample slides, and researchers all stayed nice and dry while they told NCSU students about all the different kinds of neurochemical research occurring right here at NC State!

Summer Research - Happened So Fast

NC State offers amazing opportunities for undergraduates to engage, develop, present, and publish research. In our lab, we’re very proud to have Hannah Stylers. Hannah is just now starting her junior year and already rocks some impressive research credentials!

Hanna presented her work on enzyme modified electrodes this summer during the 18th Annual NCSU Summer Undergraduate Research and Creativity Symposium. Working under one of our 2nd year grad students, Hannah has been developing methods for electrochemical detection of new analytes not previously detectable by FSCV.

Congrats, Hannah! She will be continuing her summer projects into the school year—exploring the brain’s use of glucose and lactate in real time.

Neurochemical Monitoring and Drift Subtraction

We may be biased, but FSCV is a beautiful technique. However, sometimes our signal can get a little muddled with pH shits and drift due to changes in the brain or on our electrode. Our technique uses background subtraction to look at analyte of interest, so background drift can mess up this signal. As such, a lot of neuroscientists will monitor chemical release for a minute or two before collecting a new background to avoid drift problems.

Wouldn’t it be nice to monitor your experiment for longer? Maybe even clean up some of that drift, interference, and pH?

New from the Sombers’ lab, Carl Meunier has a solution for you!

Using a small potential waveform as a predictor of drift, Carl can view drift over time as it occurs without interrupting our signal of interest! Now we can look at dopamine fluctuations over longer periods of time without sacrificing the quick-scan measurements.

This technique not only helps clean up your data but can more accurately report dopamine concentrations during large release events with interference.

Monitoring Glucose and Lactate with Electrochemistry

Electrochemical circuits are often used to study energy, but what about biological sources of energy? How the brain uses its energy stores is still not fully understood. As such, Sombers’ lab is looking for answers.

Alex Forderhase has been producing some sweet data using enzyme-modified electrodes for glucose and lactate monitoring. Here she is presenting her work last month for the 20th Annual Student/Postdoc Symposium of the W.M. Keck Center for Behavioral Biology:

Alex has been crafting new techniques for looking at electro-chemically inactive molecules. By bringing in new molecules for analysis by FSCV, she can monitor brain activity in new, unexpected ways!

Meet Our 2019 Lab

The Sombers lab has been kicking it into high gear with graduating students, post-docs moving on to their next big opportunity (congrats Dr. Sam Smith!), and training three new first-year students.

Finally, we’ve all been able to rendezvous for a group photo. Meet the new Sombers lab!

Here’s to dopamine, peptides, and electrochemistry for all its use in analyzing the brain!

Sombers Defends Six-Year Title at Winter Brain

This year’s Winter Conference on Brain Research (Winter Brain) took place in the beautiful Snowmass, Colorado. With powder this fresh and crisp, who could resist tackling the trails and carving it up? Our lab’s P.I., Dr. Sombers, is no exception. She has been killing it on the slopes! Defending her title for 2019’s Smitty Stevens Memorial Race, Sombers cinched a victory for fastest female racer.

This victory makes Dr. Sombers a six-time champion. Can anyone take down this Winter Queen? You’ll have to catch her first!
