Octopamine signaling from clock neurons plays dual roles in Drosophila long-term memory.

PLoS Genetics
Circadian clock genes are best known for regulating circadian rhythms, but they also play crucial roles in memory processes. This suggests that memory is modulated by neural networks containing clock neurons, although the underlying mechanisms remain ...

Semantic similarity dissociates shortfrom long-term recency effects: testing a neurocomputational model of list memory [PDF]

, 2006
The finding that recency effects can occur not only in immediate free recall (i.e., short-term recency) but also in the continuous-distractor task (i.e., long-term recency) has led many theorists to reject the distinction between short- and long-term ...

Novel dual-channel long short-term memory compressed capsule networks for emotion recognition [PDF]

Expert Systems with Applications, 2022
Recent analysis on speech emotion recognition has made considerable advances with the use of MFCCs spectrogram features and the implementation of neural network approaches such as convolutional neural networks (CNNs). Capsule networks (CapsNet) have gained gratitude as alternatives to CNNs with their larger capacities for hierarchical representation ...

Dual Memory LSTM with Dual Attention Neural Network for Spatiotemporal Prediction

Sensors, 2021
Spatiotemporal prediction is challenging due to extracting representations being inefficient and the lack of rich contextual dependences. A novel approach is proposed for spatiotemporal prediction using a dual memory LSTM with dual attention neural ...

Dual effect of morphine in long‐term social memory in rat [PDF]

British Journal of Pharmacology, 2013
Background and PurposeBimodal dose–response relationships have been demonstrated in animals and humans following morphine administration. We examined if systemic administration of morphine, in extremely low (μg) and high (mg, analgesic) doses, changed the learning process.Experimental ApproachIn the social learning test, an adult rat investigates a ...

A Kinase to Remember: Dual Roles for MAP Kinase in Long-Term Memory [PDF]

Neuron, 1997
The selective down-regulation of the transmembrane apCAM isoform has been proposed to remove inhibitory constraints on neuronal outgrowth by promoting the disassembly of adhesive contacts between sensory neuron processes that normally inhibit growth. However, any role that the internalization of the transmembrane form of apCAM plays in the relief of ...

Long‐term SARS‐CoV‐2‐specific and cross‐reactive cellular immune responses correlate with humoral responses, disease severity, and symptomatology

Immunity, Inflammation and Disease, 2022
Background Cellular immune memory responses post coronavirus disease 2019 (COVID‐19) have been difficult to assess due to the risks of contaminating the immune response readout with memory responses stemming from previous exposure to endemic ...

Long memory in the Ukrainian stock market [PDF]

, 2013
This paper examines the dynamics of stock prices in Ukraine by estimating the degree of persistence of the PFTS stock market index. Using long memory techniques we show that the log prices series is I(d) with d slightly above 1, implying that returns are
