An Investigation into the Mechanisms Underlying Mnemonic Precision
… imagery. Specifically, we examined perceptual pattern completion, the process that enables us to recognize an entire object from a partial stimulus, and asked if this process is differentially impacted by visual disruption in aphantasics. We find that while aphantasics have intact pattern …

Tracking The Flow of Information Through The Hippocampal Formation In The Rat
… two competitive, yet complementary, processes. Pattern separation, hypothesized to occur in the dentate gyrus (DG), refers to the ability to decrease the similarity among incoming information by producing output patterns that overlap less than the inputs. In contrast, pattern completion, …

An Enhanced Learning for Restricted Hopfield Networks
… are useful for different applications such as pattern restoration, pattern completion/generalization, and pattern association. In this study, we propose an enhanced training method for RHN which not only improves the convergence of the training sub-routine, but also is shown to enhance the …

Effects of Memorability on Mnemonic Discrimination
… across memory for similar events. Hippocampal pattern separation permits the differentiation between similar experiences, while pattern completion allows for the reconstruction of experiences from partial cues. However, these hippocampal computations have yet to be examined in the context of …

An Examination of Hippocampal and Prefrontal Contributions to Spatial Learning and Memory using Immediate Early Gene Imaging
… with flexible spatial memory recall (i.e. pattern completion). Finally, we revealed that spatial memory deficits induced by NMDA receptor blockade could be partially prevented by extended environmental experience.

Source Code Matching for Reuse of Formal Specifications
… With Substitution and Generation) algorithm for pattern completion and generate new specifications into our target/problem code. Finally, we present our evaluation and show that between structurally similar programs, the formal specifications can be fully transferred and successfully verified. …

Engrams, Neurogenesis, and Forgetting
… the initial learning event. In a process akin to pattern completion, memory recovery was associated with reinstatement of both hippocampal and cortical engram neurons. Recent work from our lab has shown that hippocampal neurogenesis promotes forgetting in both infants and adults. In project 3, the …

The Medial Entorhinal Cortex's role in temporal and working memory : characterization of a mouse lacking synaptic transmission in Medial Entorhinal Cortex Layer III
… synaptic transmission is also necessary for pattern-completion contextual recall in the pre-exposure contextual fear conditioning paradigm. Contrary to previous literature, the MEC-II to CAl pathway is not necessary for consolidation of spatial memories and anatomical tracings using this …

Using Multimodal MRI Techniques to Understand the Role of Hippocampus in Schizophrenia
… functions in dentate gyrus could decrease its pattern separation function. Multimodal MRI techniques including proton magnetic resonance spectroscopy (1H-MRS), cerebral blood volume (CBV), cerebral blood flow (CBF) and functional MRI at 3T were used to examine the metaplasticity model and probe …
