“…Subjects com-pleted slightly different versions of this paradigm, the details of which are described in the following paragraphs. These versions were programmed and displayed to subjects using the Panda Experiment Programming Library (Solway et al, 2013), which is a Python-based wrapper around the open-source game engine Panda3d (with 3D models created using Autodesk Maya) or the Unity Game Engine (Unity Technologies).…”

The medial temporal lobe (MTL) is known as the locus of spatial coding and episodic memory, but the interaction between these cognitive domains as well as the extent to which they rely on common neurophysiological mechanisms is poorly understood. Here, we use intracranial electroencephalography and a hybrid spatial-episodic memory task (29 subjects, 15 female) to determine how spatial information is dynamically reactivated in subregions of the human MTL and how this reactivation guides recall of episodic information. Our results implicate theta oscillations across the MTL as a common neurophysiological substrate for spatial coding in navigation and episodic recall. We further show that our index of retrieved spatial context is high in the hippocampus (HC) in an early time window preceding recall. Closer to recall, it decreases in the HC and increases in the parahippocampal gyrus. Finally, we demonstrate that hippocampal theta phase modulates parahippocampal gamma amplitude during retrieval of spatial context, suggesting a role for crossfrequency coupling in coding and transmitting retrieved spatial information.

Memory retrieval modulates spatial tuning of single neurons in the human entorhinal cortex

The medial temporal lobe (MTL) is critical for both spatial navigation and memory. While single neurons in the MTL activate to represent locations in the environment during navigation, it remains unclear how this spatial tuning relates to memory for events involving those locations. We examined memory-related changes in spatial tuning by recording single-neuron activity from neurosurgical patients performing a virtual-reality object-location memory task. We identified "memory-trace cells" whose activity was spatially tuned to the retrieved location of the specific object that subjects were cued to remember. Memory-trace cells in the entorhinal cortex (EC), in particular, encoded discriminable representations of different memories through a memory-Users may view, print, copy, and download text and data-mine the content in such documents, for the purposes of academic research, subject always to the full Conditions of use:
