New paper out

In our new review paper, “White Matter Plasticity in Anxiety: Disruption of Neural Network Synchronization during Threat-Safety Discrimination”, we argue that stress- and anxiety-related disorders are associated with altered myelin plasticity. In turn, changes in myelin plasticity, compromise synchronous communication within circuits that are crucial for proper learning of threat - safety discrimination.

How can we boost the ability to learn about safety? When we amplify the salience of stimuli that signal safety, we improve their effectiveness. But that’s not all - we also improve discrimination of new non-threatening stimuli, and increase exploration of new environments, thereby decreasing generalized fear.

Our new paper is out showing these positive behavioral effects of Salient Safety training in the Safety issue of Behavioural Brain Research.

We Welcome Emma to the lab!

Emma Denholtz has officially joined the lab and is fully immersed in our work on circuits that encode safety signaling in the brain. In this period of uncertainty (and associated anxiety), we’re very interested in figuring out how the brain extracts information about cues that organisms rely on for safety, as a means to relieve anxiety. Emma is working on using behavior, electrophysiology, neuroanatomy, and calcium signaling to delve into this question. Happy to have you on board!

July 13th - FENS virtual seminar session (13:00 - 14:30 British Summer Time!)

If you are attending FENS, virtually stop in to say hello at our session, where we on focus on how to develop new therapeutic approaches to battle fearful and addictive memories.

Salient Safety Conditioning Improves Novel Discrimination Learning.

Overgeneralized fear is a prevalent symptom in disorders of anxiety, and we are interested in finding therapeutic approaches to increase discrimination of non-threat in high-anxiety populations. We show that high anxiety mice (that also typically have high overgeneralized fear, like humans), improve in learning outcomes and discriminate non-threatening stimuli better after we train them on salient safety cues. It’s possible that our salient safety paradigm, trains the same networks as will later be active during non-threatening stimuli.

Great teamwork by Itzik and Jenny in the lab!

Does Wikipedia do a good job covering the work that women do in STEM?

In their blog piece, Rebecca Zhang from the lab and Mackenzie Lemieux from Kay Tye’s lab (Salk Institute) highlight how building Wikipedia pages for women in STEM is a game changer for disseminating the scientific accomplishments of women working in science. The recognition has a myriad benefits, including helping prospective graduate students, like Rebecca, find out about potential mentors and pinpoint suitable graduate programs that might never be discovered otherwise.

Take a read!

Talk at the Advanced Science Research Center

Looking forward to sharing our work at the ASRC Lunch & Learn online seminar series on Thursday, June 4th from 12:00 - 1:30.

I will be discussing “Novel pathways of fear suppression learning”.

Congratulations to Rebecca on winning the Fulbright Scholarship!

In the fall, Rebecca will be heading off to Germany to work with Nadine Gogolla at the Max Plank Institute of Neurobiology to study the insular cortex. In the lab Rebecca has been working on the pathways linking the prefrontal cortex, amygdala, and the basal forebrain in emotion regulation, which is a perfect segue for this next stage in her research career. Awesome job!

Response to COVID19

FaceShields.jpg

Our lab PPE went out to medical staff in NYC, and we are 3D printing face shields that are going out to hospitals in NY, NJ, and PA. Special thanks to Rebecca for optimizing the design for our printer, to allow for scaling up our face shield production! We are printing a modified version of the original design by Carbon, which works with our Form2 Formlabs printer (Draft or Tough resin).

There are a variety of online communities focused on 3D printing PPE, including NYC Makes PPE, and FormLabs.
