There is strong evidence that reactivation of a memory returns it to a labile state, initiating a restabilization process termed reconsolidation, which allows for updating of the memory. In this study we investigated reactivation-dependent updating using a new positively motivated spatial task in rodents that was designed specifically to model a human list-learning paradigm. On Day 1, rats were...

Several lines of evidence in humans and experimental animals suggest that the hippocampus is critical for the formation and retrieval of spatial memory. However, although the hippocampus is reciprocally connected to adjacent cortices within the medial temporal lobe and they, in turn, are connected to the neocortex, little is known regarding the function of these cortices in memory. Here, using ...

Sammendrag/Abstract: This report gives a brief overview of different applications, problems and methods related to pattern recognition in music. Many of the applications of musical pattern recognition are connected to music information retrieval. This area covers fields like information retrieval, signal processing, pattern recognition, artificial intelligence, databases, computer music and mus...

Avoidance is considered as a central hallmark of all anxiety disorders. The acquisition and expression of avoidance, which leads to the maintenance and exacerbation of pathological fear is closely linked to Pavlovian and operant conditioning processes. Changes in conditionability might represent a key feature of all anxiety disorders but the exact nature of these alterations might vary across d...

Purpose To explore whether philosophical insights from Plato’s dialogue ‘Parmenides’ on the complex and often paradoxical nature of change can illuminate the nature of information retrieval (IR). IR is modeled as a dialectic process involving mutually dependent yet conflicting forces between the subjective and the objective. These forces operate to produce change in the subjective experience of...

We describe a system for rapidly determining document similarity among a set of documents obtained from an information retrieval (IR) system. We obtain a ranked list of the most important terms in each document using a rapid phrase recognizer system. We store these in a database and compute document similarity using a simple database query. If the number of terms found to not be contained in bo...
