Experimental evidence implies that L1 and neural cell adhesion molecule (NCAM) are involved in long-term memory formation. Changes in their expression and glycosylation appear to modify the synaptic strength underlying memory consolidation. Interference with L1 and NCAM function in a variety of learning tasks in different species severely attenuates memory consolidation, indicating their involv...
The aim of this editorial note is to interpreter the assumption that muscle fiber has indeed memory ability. Muscle memory is a relatively new feature of all the characteristics ascribed to skeletal muscle cell (fiber). Muscle cell capacity to unite and fuse with a neighboring cell is defined as 'syncytium' and it exists in the first cell development, but also as a result of the development of ...
The dorsolateral prefrontal and posterior parietal cortex play critical roles in mediating attention, working memory, and executive function. Despite proposed dynamic modulation of connectivity strength within each area according to task demands, scant empirical data exist about the time course of the strength of effective connectivity, particularly in tasks requiring information to be sustaine...
This research contrasts two hypotheses concerning componential storage of meaning. The Complexity Hypothesis assumed by Fodor (The language of thought, NY: Crowell, 1975), Kintsch (The representation of meaning in memory, Hillsdale, NJ : Erlbaum, 1974), and Thorndyke (Conceptual complexity and imagery in comprehension and memory . Journal of Verbal Learning and Verbal Behavior, 1975, 14, 359-36...
Recent research and meta-analytic reviews suggest that 1 observed pattern of impaired and intact memory performance with advancing age is a deficit in measures of episodic but not semantic memory. The authors used computational modeling to explore a number of age-related parameters to account for this pattern. A 2-parameter solution based on lifelong experience successfully fit the pattern of r...
It is well established that the memory strength of studied items is more variable than the strength of new items on tests of recognition memory, but the reason why this occurs is poorly understood. One account for this old item variance effect is based on single-process theory, which proposes that this effect is due to variability in how well items are initially encoded into memory (i.e., the e...
Episodic memory performance is the result of distinct mental processes, such as learning, memory maintenance, and emotional modulation of memory strength. Such processes can be effectively dissociated using computational models. Here we performed gene set enrichment analyses of model parameters estimated from the episodic memory performance of 1,765 healthy young adults. We report robust and re...
