Summary of "The neural basis of complex audiovisual objects maintenances in working memory."

Working memory research has primarily concentrated on studying our senses separately; the neural basis of maintaining information from multiple sensory modalities in working memory has been not well elucidated. It is debated whether multisensory information is maintained in the form of modality-specific representations or amodal representations. The present study investigated what brain regions were engaged in both types of complex audiovisual objects maintenances (semantically congruent and incongruent) using functional magnetic resonance imaging and conjunction analysis, and examined in which form to maintain multisensory objects information in working memory. The conjunction analysis showed that there was common brain regions activation involving left parietal cortex (e.g., left angular gyrus, supramarginal gyrus, and precuneus) while maintaining semantically congruent audiovisual object, while the common brain regions activation including the bilateral angular, left superior parietal lobule, and left middle temporal gyrus was found during maintaining semantically incongruent audiovisual objects. Importantly, the shared conjoint brain regions activation consists of bilateral angular gyrus and left middle frontal gyrus was observed while maintaining both types of semantically congruent and incongruent complex audiovisual objects. And these brain regions may play different role while maintaining these complex multisensory objects, such as supramodel storage per se and intentional attention. The findings of the present study may support the amodal view that working memory has a central storage system to maintain multisensory information from different sensory inputs.

Recurrent Neural Networks With External Addressable Long-Term and Working Memory for Learning Long-Term Dependences.

Learning long-term dependences (LTDs) with recurrent neural networks (RNNs) is challenging due to their limited internal memories. In this paper, we propose a new external memory architecture for RNNs...

Working memory capacity is enhanced by distributed prefrontal activation and invariant temporal dynamics.

The amount of information that can be stored in working memory is limited but may be improved with practice. The basis of improved efficiency at the level of neural activity is unknown. To investigate...

The interdependence of attention, working memory and gaze control: behavior and neural circuitry.

Visual attention, visual working memory, and gaze control are basic functions that all select a subset of visual input to guide immediate or subsequent behavior. In this review, we focus on the relati...

Working memory improves developmentally as neural processes stabilize.

Working memory performance is a key indicator of cognitive and developmental status. While recent evidence indicates that stabilizing neural gain supports the stabilization of working memory during ad...

Medical and Biotech [MESH] Definitions

Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.

An enduring, learned predisposition to behave in a consistent way toward a given class of objects, or a persistent mental and/or neural state of readiness to react to a certain class of objects, not as they are but as they are conceived to be.

A term used in Eastern European research literature for the functional neural unit that provides the basis for differential sensitivity; the analyzer consists of receptor, afferent nerves, and their central connections. (From Campbell's Psychiatric Dictionary, 8th ed.)

Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI). (From Memory 1997 Jan-Mar;5(1-2):49-71)

Type of declarative memory, consisting of personal memory in contrast to general knowledge.
