JG Week 9

This week was slightly chaotic due to everything that was taking place in the lab. I continued running some of the rats on the Linear Track and also some on the W-maze. The Linear Track rats are improving, but the W-maze rats are not learning their task too well. However, we were not too focused on the Linear Track and W-maze this week because about 15 rats were undergoing surgery for a new project. Unlike the hyperdrive surgery where the rats are implanted with permanent electrodes, this surgery consists of injecting a certain substance that can later be used to locate areas of brain activity under certain conditions. I was allowed to watch the surgeries take place after running my rats on the mazes. I got to see the craniotomy (exposing the brain by removing a part of the skull) and the suturing (closing the head back up).
