Also I would write this the same way you write resume descriptions. Just super bland and basic. When I was writing my AACOMAS app I would include a sentence about how this experience was valuable in medical school or as a physician somehow. I can show you two personal examples.
This is what I would write on the CV application: Researched aggression in the hypothalamus in rat models in both wet and dry labs. Sliced and mounted samples for analysis and imaged and analyzed dyed slides with in-depth understanding of structure of hypothalamus.
Versus what I wrote for AACOMAS: As a research assistant, I studied aggression-mediated gene activation in the ventromedial hypothalamus. I worked in a wet lab embalming, mounting, and staining mouse brains and at a separate facility where I imaged and analyzed our slides using Brain Maps 4.0. Dr. X used this research for The X Project, a global effort to map the cytoarchitecture of the brain. I developed the ability to differentiate minute regions within the hypothalamus from hazy, nissl- stained slides and have furthered my appreciation for the complexity of the brain.
