Profile

Guifen has recently started her own research group at the school of Biological and Chemical Sciences, QMUL, following her post-doctoral research at University College London (with Prof. John O’Keefe and then Prof Francesca Cacucci).

Guifen’s group studies the neuronal basis of spatial cognition and memory in mice, making use of the state-of-the-art virtual reality techniques and in vivo electrophysiological recording techniques.

Research

Research Interests:

The ability to navigate is an essential skill required by both humans and animals. Animals can use sensory cues across modalities, such as visual, auditory, olfactory, integrated with self-motion cues, to find their way home from a food searching journey. Neural activity in the hippocampus and adjacent cortical areas, has been shown to correlate with the physical location of an organism. However, it is not clear how an internal unified representation of space, which supports navigation, is generated by integrating sensory inputs across modalities. 

 Virtual reality offers a powerful tool for investigating spatial cognition, allowing environmental manipulations that are impossible in the real world. Two-dimensional immersive virtual reality allows a close approximation of spatial representation in the real world. Hence, my laboratory is studying the across-modal navigation in virtual environments, combining virtual reality techniques with in vivo electrophysical recording and two-photon imaging.
