The spontaneous replay of patterns of activity related to past experiences and memories is a
striking feature of brain activity, as is the coherent activation of sets of brain areas …

Humans and animals use mental representations of the spatial structure of the world to
navigate. The classical view is that these representations take the form of Euclidean …

We developed a miniaturized two-photon microscope (MINI2P) for fast, high-resolution,
multiplane calcium imaging of over 1,000 neurons at a time in freely moving mice. With a …

The last decade has produced exciting new ideas about retrosplenial cortex (RSC) and its
role in integrating diverse inputs. Here, we review the diversity in forms of spatial and …

The mammalian hippocampal formation contains several distinct populations of neurons
involved in representing self-position and orientation. These neurons, which include place …

The hippocampus and its extended network contribute to encoding and recall of episodic
experiences. Drawing from recent anatomical, physiological, and behavioral studies, we …

The retrosplenial cortex is reciprocally connected with multiple structures implicated in
spatial cognition, and damage to the region itself produces numerous spatial impairments …

This paper reviews the recent experimental finding that neurons in behaving rodents show
egocentric coding of the environment in a number of structures associated with the …

Bouts of high frequency activity known as sharp wave ripples (SPW-Rs) facilitate
communication between the hippocampus and neocortex. However, the paths and …

There has been considerable research showing populations of neurons encoding for
different aspects of space in the brain. Recently, several studies using two-photon calcium …
