Sense of place
My lab studies the activity of single neurons in the hippocampus and in those regions that project to it, in order to understand what environmental information the cells use to form their map of space. We study rats and mice, and our collaborators extend those findings into studies in humans. Our experimental setup is shown below, in which a rat explores (searching for food) while the activity of hippocampal neurons is monitored.
Below are shown typical recordings from each of the four main spatial cell types; a place cell, a head direction cell, a grid cell and a border cell.
