Object-centered population coding in CA1 of the hippocampus

Abstract

Objects and landmarks are crucial for guiding navigation and must be integrated into the cognitive map of space. Studies of object coding in the hippocampus have primarily focused on activity of single cells. Here we record simultaneously from large numbers of hippocampal CA1 neurons to determine how the presence of a salient object in the environment alters single-neuron and neural-population dynamics of the area. Only a small number of cells fired consistently at the object location, or at a fixed distance and direction from it; yet the majority of the cells showed some change in their spatial firing patterns when the object was introduced. At the neural population level, these changes were systematically organized according to the animal’s distance from the object. This organization was widely distributed across the cell sample, suggesting that some features of cognitive maps – including object representation – are best understood as emergent properties of neural populations.
