Chan Zuckerberg Initiative on Instagram: "These are the cells in the hippocampus, the area of the brain that is key for learning and memory. This image comes from an experiment where researchers used a genetic trick to make cells glow green if they are activated by an experience. In the top part of the image, cells in green are those responding to a negative experience. In the bottom, cells glowing green are responding to positive experiences. Grantee Steve Ramirez wants to learn more about how these cells encode memories. “Memories thread and unify our overall sense of being. They're at the core of who we are. The process of figuring out how memories work means I get to explore something so fundamental about our innermost biology, about our humanity—and I find that endlessly inspiring.” #science #biology #scicomm #neuroscience #neurology #health #brain #neuro #genetics #biomedicine #microscope #microscopy"
