Innovative Lab Contest Winner

We are pleased to announce that Tracy Hodgson, Assistant Professor of Instruction, Northwestern University, has won the Innovative Lab Contest sponsored by iWorx. Here's the winning lab abstract.
 

Drosophila Electroretinogram (ERG)

Using simple extracellular recording electrodes (a thread wick on the surface of the eye, and a broken intracellular pipet electrode inserted into the fly's thorax for the ground), students recorded electroretinograms (ERGs) from unanesthetized, restrained Drosophila.

 

Students examined the spectral sensitivity of the ERG with color filters, and recorded the ERGs of wild type and mutant flies (white and orange eye) to observe any changes in the receptor and synaptic potentials underlying the ERG that were affected by the presence or absence of screening pigments.

 

The full lab will be featured in our September 2015 newsletter.

 

About the Professor

Tracy Hodgson, Innovative Lab Contest WinnerTracy is an Assistant Professor of Instruction at Northwestern University. She has been at NU since 2001, teaching physiology and neurobiology lecture and laboratory courses. She received her bachelor's degree in biology from Wayne State University in Detroit (her home town), and a  Ph.D. in physiology and neuroscience from the University of Pittsburgh School of Medicine. For her doctoral dissertation she studied learning and memory in the invertebrate model Hermissenda (a type of sea snail called a nudibranch).

 

Tracy was awarded an iWorx isolated ECG/EMG/GSR Biopotential Recording Module in appreciation of her effort.

 

Thanks to all of you who submitted abstracts for the contest and congratulations to Randi Lite, Simmons College, who won the $100 Amazon gift card.

 

Have a great summer everyone!

Physiology in the News

Read our monthly digest of fun facts about what’s happening in the world of Anatomy & Physiology. Check out what your colleagues are doing and learn about new breakthroughs and advances in and out of the lab.

Artificial Muscles and Onion Skins
Researchers discover a way to create artificial muscles from the skin of onions.
 

Chicken Grows Face of Dinosaur
A molecular mechanism for the origin of a key evolutionary innovation, the bird beak and palate, revealed by an integrative approach to major transitions in vertebrate history. Both of these articles deal with the evolution of birds. How did that beak actually form from the toothy jaw of a velociraptor?
 

Inside Out and Upside Down
Researchers have captured the first 3D video of a living algal embryo turning itself inside out. This discovery will hopefully lead to new knowledge of embryonic formation.
 

Finding the Body Clock’s Molecular Reset Button
Researchers at McGill and Concordia Universities have discovered the mechanism involved in adjusting rhythms of the circadian clock.
