Neurons are always fun. Beautiful image of two STG neurons stained by students in our Biophysics course.  Social distancing and masks are not keeping us from research and education!

Our PhD candidate Margaret DeMaegd is a finalist for the ISU 'Image of Research' contest with her photo "Carcinization". Congrats!

The people's choice poll will be coming soon!

Our new review paper on the effects of climate change on crustacean nervous systems is out

Our newest paper with Steffen Harzsch in Greifswald discusses crustacean brains in times of climate change!

Newest paper is out in the Journal of Undergraduate Neuroscience Education

In this paper, we outline approaches for STEM undergraduates to identify neuronally expressed genes. We provide a helpful protocol for physiologists who want to implement molecular and genetic methods in their own labs. We also identify a GABA-A receptor in crayfish:

Finding the solution: Animal physiology lab makes most of hybrid format

posted Feb 16, 2021, 3:48 PM by Wolfgang Stein

In a lab designed to illustrate how living organisms operate, it only makes sense there’d be an entire week dedicated to respiration systems. In previous Biological Sciences (BSC) 283: Animal Physiology courses, students would measure lung capacity and simulate different chronic conditions such as asthma.

But with the COVID-19 pandemic, one of the fastest ways the novel virus travels is through the air. So, naturally, that type of assignment in a lab classroom was out of the question. Illinois State students in Dr. Stein's class proved once again they could pivot to make the best of the situation. Realizing quickly the original experiment wouldn’t work, the class used crayfish instead, placing them in both low and high saline solutions and study respiratory activity in an animal model.

New temperature paper is out in PLoS Comput Biol

How do axons deal with acute temperature changes? Our newest paper has the answer:

What makes ticks tick: Dr. Städele studies their every move!

Ticks love to bite her, and she’d like to find out why, or why they do anything, like attach to one host but ignore another.

Few researchers have studied how a tick’s brain works, but that’s what caught the attention of Dr. Carola Städele. As a post-doctoral researcher in the Stein laboratory, she studies a tick’s every move by recording them as they crawl around their Plexiglass home.

Phi Sigma Grants for our graduate students

Congratulations to our award winners at the 2020 School of Biological Sciences Award Ceremony hosted via Zoom!

Josselyn Gonzalez received the Mockford-Thompson Summer Research Fellowship, Maggie DeMaegd received the Outstanding PhD Student Award, and Liisi Vink-Lainas received the BSC 101 Teaching Assistant Award.

All three also received Weigel Research Grants! Lots of excitement coming from the Crablab!!

IMSAloquium - High School Student Presentations

posted Apr 22, 2020, 7:39 AM by Wolfgang Stein

Our high school student Saisu Talasu presented her research on Dopamine receptors today at the annual colloquium of the Illinois Mathematics and Science Academy, IMSAloquium.

Like all seminars these days, the presentations were given on Zoom - a shout-out to the organizers to make the colloquium happen. Great talk, too!
