Her PhD is in Neuroscience and her research career spans universities in Asia, North America and Europe, including the lab of Nobel Laureate Prof. John O'Keefe.Dr Chen’s research group at QMUL focuses on the neuronal basis of spatial cognition and memory in mice, making use of state-of-the-art virtual reality techniques and in vivo electrophysiological recording (tetrode and Neuropixels probe recordings). The research is primarily funded by the Biotechnology and Biological Sciences Research Council (BBSRC). ORCID iD: 0000-0002-5459-660X Twitter: @GuifenChen Undergraduate TeachingFundamentals of Neurobiology (SNU209) ResearchResearch 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 electrophysiological recording (tetrode and Neuropixels probe recordings) and 2-photon imaging.
