Project Title: Mapping the Development of Repetitive Behaviors in Mice
BASIS Advisor: Dr. Hight
Internship Location: Graybiel Laboratory at MIT
Onsite Mentor: Dr. Emily Hueske
What does instigating and quantifying the development of repetitive behaviors in autism spectrum disorder (ASD) model mice reveal? The SHANK3 gene, which is found in the 22q13 chromosome, is one of the autism gene candidates. A mutation in this gene has been found in 1-2% of individuals with ASD. To this end, SHANK3 mice are used in studies focused on the development of repetitive behaviors, an aspect of autism. For my internship, I will work with Dr. Emily Hueske at Graybiel Laboratories to research the development of repetitive behaviors in SHANK3 model mice through the use of softwares: DeepLabCut and B-SOiD. DeepLabCut provides a marker-less (as opposed to the old method of attaching physical markers to animals) pose mapping software. B-SOiD can provide specific clustering of pose movement data from DeepLabCut. These softwares will provide information on model mice that have been affected by Designer Receptors Exclusively Activated by Designer Drugs (DREADDs), which will allow for manipulation of the striatum, part of the brain involved in motor function. The goal of this project is to develop a better understanding of the development of repetitive behaviors in autism model mice.

This week I worked on making a model from the top down perspective from older videos that my mentor sent me. The purpose of this is mainly for comparison to bottom up video data and for this type of work to be publishable both camera angles would be necessary. However, I ran into some noticeable […]

This week I worked on making the model that my mentor and I intend to use for the bottom up camera perspective. I trained DeepLabCut on a total of 6 videos: 2 cane mice, 2 Shank mice, and 2 amphetamine mice. The reason for including these different types in addition to the shank mice is […]

Hello! This fourth week I managed to figure out some solutions to the problems I mentioned last week. Regarding adding new videos to an already created project, the problem lies with the way they are added. When using the GUI feature to add new videos, a symlink is added to the project folder instead of […]

For my third week, I did some labeling and created a model for a few habituation videos. These habituation videos are taken while the mice acclimate to the chamber in which they are recorded. I will later analyze videos from a later period after they have been in the chamber multiple times. I did encounter […]

Hello! This second week I continued to work with DeepLabCut and B-SOID. The main change was that my advisor purchased 60fps cameras and I ran the two aforementioned programs on new videos of mice. This time there was a noticeable difference as I found labeling pose markers to be easier as the mouse body parts […]

This first week I started my virtual internship with Graybiel Laboratory as part of my senior project. My work mainly consisted of working with my on-site mentor, Emily Hueske, to try and run a sample set of data through DeepLabCut and B-SOID. This sample video consisted of about 7 minutes wherein a mouse is filmed […]

Hello! My name is Jason Lee and I am currently a senior at Basis Independent McLean. For my senior project, I want to better understand how animal movement and behavior mapping programs can be used to understand repetitive behaviors due to mutations in mice. I have a particular interest in this topic because of my […]
