Protein synthesis-dependent associative long-term memory in larval zebrafish.
The larval zebrafish is a model organism to study the neural circuitry underlying behavior. There exist, however, few examples of robust long-term memory. Here we describe a simple, unrestrained associative place-conditioning paradigm. We show that visual access to a group of conspecifics has rewarding properties for 6- to 8-day-old larval zebrafish. We use this social reward as an unconditione...
متن کاملAssociative Long Short-Term Memory
We investigate a new method to augment recurrent neural networks with extra memory without increasing the number of network parameters. The system has an associative memory based on complex-valued vectors and is closely related to Holographic Reduced Representations and Long Short-Term Memory networks. Holographic Reduced Representations have limited capacity: as they store more information, ea...
متن کاملSurface expression of NMDA receptor changes during memory consolidation in the crab Neohelice granulata.
The aim of the present study was to analyze the surface expression of the NMDA-like receptors during the consolidation of contextual learning in the crab Neohelice granulata Memory storage is based on alterations in the strength of synaptic connections between neurons. The glutamatergic synapses undergo various forms of N-methyl-D aspartate receptor (NMDAR)-dependent changes in strength, a proc...
متن کاملSpaced training induces normal long-term memory in CREB mutant mice
BACKGROUND The cAMP responsive element binding protein (CREB) is a transcription factor the activity of which is modulated by increases in the intracellular levels of cAMP and calcium. Results from studies with Aplysia, Drosophila and mice indicate that CREB-activated transcription is required for long-term memory. Furthermore, a recent study found that long-term memory for olfactory conditioni...
متن کاملProtein synthesis is required for the enhancement of long-term potentiation and long-term memory by spaced training.
Spaced training is generally more effective than massed training for learning and memory, but the molecular mechanisms underlying this trial spacing effect remain poorly characterized. One potential molecular basis for the trial spacing effect is the differential modulation, by distinct temporal patterns of neuronal activity, of protein synthesis-dependent processes that contribute to the expre...
