Distributed associative memory
… codes and Bloom filters to create high-capacity associative memories. These associative memories use principled statistical inference and are distributed as no single component contains enough information to complete the task by itself, yet the components can collectively solve the task by …

Associative Memory Processes in Schizophrenia
… in a number of domains, including episodic memory: EM). Memory for both individual items and associations between items is impaired in schizophrenia, with some indication of a more severe deficit in associative memory. Furthermore, such memory impairments have been consistently linked with …

The Impact of Emotion on Associative Memory
The effect of emotion on associative memory remains unclear. Inconsistent findings in the literature are leading to theories with opposite predictions. Obtaining a clearer view of the impact of emotion on associative memory remains of crucial importance, particularly as it could shed light on the …

An Associative Memory Trace in the Cerebellar Cortex
Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the …

Building cell assembly based associative memory with spiking neurons
Associative memory is a fundamental component of cognitive function. The CA (CA) frame-work, first proposed by Hebb, provides a biologically plausible foundation for understanding the operation of associative memory. The formation and storage of memories depends on structural changes and …

Arbitrary associative memory: a candidate cognitive endophenotype for probable Alzheimer's disease
… domains, with a particular focus on episodic memory (Study 1). As expected, effect sizes for all cognitive domains were small, and none were significantly different to zero. The largest difference between groups was found for visuospatial ability (d = 0.16), with offspring of probable AD …

Use of multimodal stimuli to facilitate associative memory in older adults
… suggested that this may be one cause of the associative memory deficit in older adults (Naveh-Benjamin, 2000), demonstrating that the associative deficit could be simulated with sensory degradation in younger adults. The present studies attempted to extend these results by using multimodal …

Towards a neocortically-inspired ab initio cellular model of associative memory
… and could be used as the basis of an associative memory. The dissertation details the relevant background and results of a series of experiments designed to accomplish this objective. The results provide encouraging empirical evidence that such a model can be used for encoding …

Effects of Priming on Subsequent Associative Memory: Testing Prediction Error and Attentional Accounts
… strong reasons to expect related processes in memory, less work has been done to investigate this. One difficulty addressing this question concerns the role of attention in memory formation; although the roles of PE and attention are theoretically distinct, when events are surprising we are …

The Energy Landscape of Associative Memory Energy Functions and Their Application to Ab Initio Protein Structure Prediction
… ab initio prediction. In particular the class of associative memory models are explicitly based on energy landscape ideas. In an associative memory model the energy of a particular conformation is a function of a set of sequence-structure correlations learned from a database of known structures. …

Mapping the time-course and content of visual predictions with a novel object-scene associative memory paradigm
… novel object-scene pairs in a paired associate memory paradigm. At test, we presented the scene first, followed after a delay by the test object, which either matched or mismatched the scene. We manipulated two key factors. 1) In all three experiments, we manipulated the severity of contextual …

Are Associations All You Need? Overcoming the Problem of One-to-Many Association and Nonlinear Relationships with Contiguity in a Bidirectional Associative Memory Framework
… model. It focused on using recurrent neural associative memories, specifically, a biological and cognitively plausible Bidirectional Associative Memory framework. The objective was to overcome its current limitations in learning one-to-many associations and nonlinear relationships. It …

Attention-memory interactions in children and young adults
Associative memory (the ability to bind parts of an event into an integrated unit) is important for encoding episodic events. Critically, associative memory changes throughout the lifespan, such that memory shows protracted development into young adulthood, then declines in older adults. In this …

Associative and Error-Driven Learning in Younger and Older Adults
<p>Previous research has consistently shown associative deficits in older adults learning and memory (Chalfonte & Johnson 1996; Naveh-Benjamin, 2000; Naveh-Benjamin, Hussain, & Bar-On 2003) that are related to decreases in hippocampal function (Driscoll et al., 2003; Mitchell, Johnson, Raye, & …

Exploring the Behavioural Effects of Compound-21 Using Novel Object Recognition and Object in Place Tests in Long Evans Rats
… When used with spontaneous behavioural tests of memory in rodents, DREADDs allow for a unique opportunity to advance our understanding of how specific neuronal populations contribute to cognition. While data on the use of DREADDs to study memory with spontaneous tasks in rats is somewhat limited, …
