Updated word search and mirror-tracing tasks for Qualtrics

I finally had some spare time to document and post the mirror tracing and word-search tasks I developed for some replication work my students and I completed ​(Cusack, Vezenkova, Gottschalk, & Calin-Jageman, 2015)​.

Each task is (I think) pretty nifty, and I’ve had lots of emails about them over the past couple of years. I’ve finally posted both code bases to github along with working demos in Qualtrics and some rudimentary instructions. The code itself is not pretty–I was learning javascript and wrote most it during a conference I was attending in Amsterdam. Still, it works, and I’m sure it could come in handy.

The mirror-tracing task is just like it sounds–participants trace an image with their mouse or track pad but the mouse movements are mirrored, making it hard to stay in the line. You can vary task difficulty by changing line thickness. There is an expected weak negative correlation with age. The script can even posts the traced images back to your server, which is cool for making figures showing how groups differ with representative data.

The word-search task is also like it sounds. You can use pre-defined grids, or the script can generate a grid for you. I’ve used it to try priming for power (control vs. power-related words hidden in the grid) and to look at frustration (by having a grid that *doesn’t* have all the target letters…mean, I know).

Kids, Neurons, and Robots

At the end of February I (Dr. Bob) visited a local elementary school as part of the Oak Park Educational Foundation’s Science Alliance Program.

I was matched up with Sue Tressalt’s Third Grade Class at Irving Elementary. For an activity, I brought along the neuroscience program’s collection of Finch Robots, a set of laptops, and the Cartoon Network simulator I have been developing (Calin-Jageman, 2017, 2018). I introduced kids to the basic rules of neural communication, and they explored Cartoon Network, learning how to make brains to get the Finch Robots to do what they wanted (e.g. avoid light, sing when touched, etc.). It was a great class, and a ton of fun.

I’m proud of Cartoon Network, and the fact that it can make exploring brain circuitry fun. It’s simple enough that the kids were able to dive right in (with some help), yet complex enough that really interesting behaviors and dynamics can be modelled.

As a kid, my most formative experience in science was learning logo, the programming language developed by Seymour Papert and colleagues at MIT. Logo was fun to use, and it made me need/want key programming concepts. I clearly remember sitting in the classroom writing a program to draw my name and being frustrated at having to re-write the commands to make a B at the end of my name when I had already typed them out for the B at the beginning of my name. The teacher came by and introduced me to functions, and I remember being so happy about the idea of a “to b” function, and I immediately grasped that I could write functions for every letter once and then be able to have the turtle type anything I wanted in no time at all.

Years later I read Mindstorms and it remains, to my mind, one of the most important books on pedagogy, teaching, and technology. Papert applied Piaget’s model of children as scientists (he had trained with Piaget). He believed that if you can make a microworld that is fun to explore, children will naturally need, discover, and understand deep concepts embedded in that world. That’s what I was experiencing back in 2nd grade–I desperately needed functions, and so the idea of them stuck with me in a way that they never would in an artificial “hello world” type of programming exercise. Having been a “logo kid” it was amazing to read Mindstorms and recognize Papert’s intentionality behind the experiences I had learning Logo.

Anyways, bringing Cartoon Network to an elementary school for a day gave me a great feeling of carrying on a tiny piece of Papert’s legacy. The insights kids develop in just an hour of playing with neural networks are amazing–the idea of a recurrent loop made immediate sense to them, and that also sets up the idea that both excitation and inhibition are important. And, like in Logo, the kids were excited to explore–to know that their experience was not dependent on getting the ‘right’ answer but on trying, observing, and trying again.

The day was fun and even better I received a whole stack of thank-you cards this week. Reading through them has kept a smile on my face all week. Here’s a sample.

This kid has some great ideas for the future of AI

“I never knew neurons were a thing at all”–the joy of discovery
“Your job seems awesome and you are the best at it”—please put this kid on my next grant review panel.

SlugLab Alum Derek Stek heading to medical school with a full ride scholarship

Graduates of the sluglab have been moving on to amazing careers. So we were excited to get the news that lab alumni and neuroscience major Derek Stek has just been offered a full scholarship to attend medical school at the School of Medicine and Public Health at the University of Wisconsin. Woo hoo!

The slug lab in summer of 2018. Derek is the tall guy on the left-side of the table; this was just before he shipped out to UCLA.

Derek spent the summer of 2017 working in the lab, and also did summer research programs at the University of Colorado (2016) and UCLA (2018). In the sluglab, Derek learned how to do extract RNA (which does *not* start by vortexing the DNA-ase) and conduct qPCR. He helped track the expression of several transcripts regulated after learning, and was a co-author on the lab’s most recent paper (Patel et al., 2018).

Derek was also a star outside of the classroom, playing a big part on the DU varsity basketball team. This year, as he finishes at DU, Derek has been working with children with autism and learning behavioral therapy.

Congrats, Derek!

New preprint on the very long-lasting transcriptional response to learning

The sluglab has a new preprint out, currently under review at the Neurobiology of Learning and Memory.  We shows that both transcription and savings can persist for as long as 2 weeks after the induction of long-term sensitization, way beyond the decay of recall.  Interestingly, all the long-lasting transcriptional changes start within 1 day of training.  Lots of student co-authors on this one; it was a *lot* of work.  Looking forward to the reviews.

When you forget

Quanta Magazine recently ran a feature article on the nature of forgetting.  The piece covers several new lines of research on forgetting, including the work we’ve been doing with Aplysia.  It’s a great piece, and it’s amazing to see strong public interest in our work.

Of course, accolades like this would not be possible if it were not for our amazing students.  Here’s the lab enjoying our end-of-summer party.

 

DU Connections and a New Slug Home

The slug lab is kicking off summer research with a brand new aquarium and mixing station for housing Aplysia.  It’s a great upgrade and an even better story that involves some strong DU connections.

The slug lab has been running for 10 years now (gasp!) and our aquariums were showing signs of wear.  Like the wooden stand on one of the tanks starting to collapse.  Pretty strong sign.  (fortunately a student was in the room as the tank started to tip; she called for help, we drained the tank, and disaster was averted).  By fall of 2017 we were down to just 1 tank and worried about how we’d get back to 2 in time for our blitz of summer research.

DU Connection Number 1: In late fall 2017 we were thrilled to receive a McNichols grant from a Dominican Alumni.  This grant was specifically targeted at funding science education at Dominican. We had some meetings and identified several great projects that could be helped by this generous gift–work to improve our greenhouse, a new measurement instrument for the PChem lab, and… a new tank for the slug lab.  Hooray, and a big thanks to the McNichols family.

DU Connection Number 2: We knew we wanted to upgrade beyond a hobbyist tank.. but there were so many options and it was difficult to determine the best path forward.   Enter DU connection #2, Romney Cirillo and his company Something Fishy.  Romney was a business major at Dominican.  When he graduated he wasn’t entirely sure what to do.  But he remembered Al Rosenbloom’s advice to find something he was passionate about and to find a way to make it a life’s work.  Combining that advice with a great entrepreneurship class he had completed, Romney decided to start a business related to his life-long interest in raising exotic fish.  He recruited a great friend as a business partner.  Something Fishy was quickly born as a full-service aquarium design and maintenance company.   Since its founding, Something Fishy has thrived by providing great service and incredible craftsmanship.  Things were going well, so Romney started giving back to DU–installing a gorgeous salt-water tank in Parmer hall.  That’s how I met Romney and got to know Something Fishy.  So, naturally, when it came time for a new tank, Romney was the first person to call.  Thank goodness for these strong DU connections.

The amazing tank.  Romney and Mike visited the slug lab, walked us through options and designed a customized setup exactly suited for our needs:

  • a bigger tank with a better filter system
  • lower to the ground with a huge lid to make experimental access easier (our students say thank you!)
  • incredibly tough and corrosion resistant tank stand (no more collapses from wooden stands)
  • better insulation to make our chillers work less hard
  • and an incredible mixing station for making salt water, complete with a DI line and an auto-shutoff (no more leaks down into the classroom below).

We just finished our first round of experiments with animals housed in the new tank… wow!  Even on the day of shipment the tank water stayed at crystal clear.  Good water -> healthy animals -> a good platform for good science.

Not only is the tank *way* better than what we had, it looks amazing–the install is clean and sharp; it really looks space age.  Best of all, the cost was not astronomical.

So – thanks to two great DU alum we have a great new home for our animals.

Romney (right) showing me the features of the tank on install day.

Here are some photos, but they don’t really do the tank justice for how cool and clean it all looks.

First fillup. Water has just had salt added.

Smiles even on tank cleaning day! The new tank setup is soooo sharp. (Melissa, Ushma, and Leticia… there are slugs in the tank, but all are hiding in the back).

Slug Lab 2018 – Summer Edition

Summer is here, so the Slug Lab is running full speed.

We’re lucky to be joined once again by a really talented and dedicated team of students.  Here’s most of us at a pizza party to inaugurate a summer of research.  

From far left we have

  • Kayla Hall, joining us from Amherst for the summer
  • Ushma Patel, who has graduated but will stay in the lab for the start of the summer (and then on to study biomedical illustration at UIC)
  • Athira Jacob, lab alum now studying for her MCAT
  • Derek Steck, lab alum who this summer will be in the UCLA summer research program this summer
  • Steven Farrell, who has graduated but is also sticking with the lab for part of the summer while prepping for the MCAT
  • Dr C-J and myself (end of the table)
  • Tanya Rosiles, new lab member
  • Everett Krause, new lab member
  • Leticia Perez, lab alum sticking around for part of the summer before heading to UofI for veterinary medicine

And not yet in the photo but planning on joining when she returns from Ireland: Shannon Wilcox

I hope I don’t jinx anything when I say that we’re off to a great start, with a very successful round of behavioral experiments and RNA isolations.  Looking forward to another great slug lab summer.

 

Slug Lab Triumph! First place in the cSFN undergraduate poster competition for Leticia Perez and Ushma Patel

So pleased and proud to announce that Leticia Perez and Ushma Patel have won first place in the Chicago Society for Neuroscience undergraduate poster competition.   Congrats Leticia and Ushma on a great presentation on the work you’ve been doing in the slug lab on the transcriptional correlates of forgetting and savings memory.

Leticia and Ushma are following up their spectacular win with exciting post-graduation plans.  Leticia is enrolling at the University of Illinois School of Vetrinary Medicine (and had her choice of programs!).  Ushma is enrolling at UIC’s prestigious medical illustration MA program (and also had her choice of programs!).  Congrats to both on all the hard work they put into collecting data, analyzing results, and presenting their exciting research.

Want to know more about the research Leticia and Ushma presented?  See their paper in Learning and Memory here: (Perez, Patel, Rivota, Calin-Jageman, & Calin-Jageman, 2017)

Not to brag, but this is the 3rd time a DU student has placed in this competition in the past 10 years (Kristine Bonnic had a 3rd place win and Tim Lazicki had a first place win).  That means DU neuroscience students have earned 1/3 of all the awards given out for undergraduate research by the Chicago Society for Neuroscience–an organization that includes Northwestern, Loyola, University of Chicago, DePaul, Midwestern, Roosevelt, North Central, and more…. relative to our student body we’re punching way above our weight!
