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 …

Rhythmic oscillations within the hippocampus are thought to synchronize various subregions during learning, maximizing efficiency of the neural circuits. In rats, the most prominent oscillation is hippocampal theta. Theta is known to be modulated by an animal’s velocity, but it has also been shown to change in response to cognitive demands. To determine if theta is important for learning and memory, EEG recordings were examined for changes in theta related to the decision point of a spatial or non-spatial T-maze task. Additionally, a straight runway served as a control to verify the consistent relationship between velocity and theta during a …
