In many organisms, the sense of smell, driven by the olfactory system, serves as the primary sensory modality that guides a plethora of behaviors such as foraging for food, finding mates, and evading predators. Using an array of biological sensors, the olfactory system converts volatile chemical inputs from an organism’s environment into well-patterned neural responses that inform downstream motor neurons to drive appropriate behaviors (e.g., moving towards food or away from danger). For many external cues, the elicited neural responses are often determined by the genetic makeup of the organism, which assigns an innate preference, or valence, for these different …

The hippocampus is the part of the brain that is involved in memory and navigation. Neurons in the hippocampus, known as place cells, fire in specific locations within this region of the brain as the subject navigates through their environment. As these cells fire, they create a map-like representation of this environment. However if the environment is altered in any way, the place cell firing pattern is adjusted to incorporate this new information. This adjustment will inevitably cause subjects to take more time to complete their task. The goal of our testing was to assess how various manipulations, both spatial …
