The hippocampus plays a critical role in memory formation, but our understanding of just what the hippocampus does and how it performs its functions are still issues of considerable controversy. To enhance our knowledge about hippocampal function, we are pursuing a combination of neuropsychological studies of the nature of memory loss in animals with damage to the hippocampus and related cortical areas, and we are pursuing electrophysiological recording studies that seek to determine how information is represented by the hippocampus and associated cortical areas.

My research interests encompass all areas of brain and behavior, as well as many different scientific subjects at large. Presently, I’m managing the Eichenbaum Lab and exploring context-dependent firing in the hippocampus and supporting structures. I’m also actively instructing and advancing educational outreach projects to share our amazing science with the children of the world.

My work is centered around understanding the neural network responsible for the formation and retrieval of contextual memory representations. Using electrophysiology techniques to record neuronal activity patterns, current work explores how cells in the prefrontal cortex represent the context in which events happen.

My current research focuses primarily on the cortico-hippocampal processing stream providing contextual or “where” information to the hippocampus. Using a combination of electrophysiology and lesion techniques, this research will examine how cortical regions such as the entorhinal and retrosplenial cortices interact with the hippocampus and medial temporal lobe during learning and memory.

My research investiages how hippocampal afferents influence intrahippocampal processing, utilizing a combination of optogenetics, pharmacology, and extracellular recording in the behaving rat.

During my PhD in Germany, my research focused on prefrontal-hippocampal interactions in neonatal rats. At that stage, these regions already communicate with each other This is presumably a prerequisite for accomplishing higher cognitive functions in adulthood. Now, I have the chance to focus on these functions while rats perform behavioral tasks. My goal is to understand how neurons in the medial prefrontal cortex encode and retrieve information about the “what” and “where” features of memory.

One of the primary goals of my research is to better understand the different mechanisms through which cells in the dentate gyrus of the hippocampus can account for differences in spatial and non-spatial features of events, contexts, and their associations. I would like to understand how the representation of these differences at the single cell level ultimately contributes to discrimination abilities in behavior. Moreover, I am interested in understanding how input into the hippocampus is deferentially processed within the dentate gyrus, CA3, and CA1 subregions and how these structures work together in the service of learning. Lastly, I am interested in the rich oscillatory activity of the dentate gyrus, the modulation of these oscillations by learning, and what we can learn from single cell and local field potential relationships within and across structures.

One day thirteen years ago, I decided not to cut class in order to attend a seminar on hippocampal neural network modeling, and I’ve been hooked on neuroscience ever since.  For my current project, I’m using genetic tools and miniaturized microscopes to examine the activity of many hippocampal neurons over long time periods.

Memory is life, as we know it. From sub-cellular processes necessary for enhanced connection, to the systems responsible for lasting cognition, I’d like to better understand how this representation of life is acquired, maintained and recalled. I’m currently fond of assessing the hippocampal formation by employing a combination of in vivo and behavioral techniques. Both up and down stream processing can be cool too.

Nicholas Robinson recently graduated from The University of Edinburgh’s Neuroscience undergraduate program where he developed a particular interest for the encoding, storage and retrieval of episodic memories. He has experience performing lesion studies and in vivo tetrode recordings from the hippocampus of behaving animals. He is also a keen tennis and squash player and enjoys hiking and rock climbing.

My research is looking to further our understanding of how the brain processes temporal information in relation to memory.  Recent studies have described a new phenomenon in pyramidal cells of dorsal CA1 in the Hippocampus of rats we’ve called “time cells”.  These cells fire at a specific time during some memory task delays similar to how place cells fire at certain locations in space. My project aims to help identify how and in which brain structures “time cells” originate, and to gain hints at how this information percolates through and is processed by the hippocampal system.

I graduated from Arizona State University with my bachelor degree in Psychology. There, I developed an interest in further understanding how the hippocampus encodes, stores, and retrieves memories. As well, I am interested in understanding how damage to the hippocampus affects memory.

I tend to focus my efforts on all things awesome.  As my graduate career is picking up momentum, awesome things include the ventral hippocampus.

I am interested in the interplay between cortical areas and the hippocampus during the processes of consolidation/reconsolidation, when short-term memory representations transform/integrate into long-term representations.  Through the use of electrophysiological and imaging techniques, I hope to investigate the role that cortical areas, primarily the medial prefrontal cortex, play in this transformation/integration.
