Coordinated Plasticity among Glutamatergic and GABAergic Neurons and Synapses in the Barrel Cortex Is Correlated to Learning Efficiency

Frontiers in Cellular Neuroscience, 2017
Functional plasticity at cortical synapses and neurons is presumably associated with learning and memory. Additionally, coordinated refinement between glutamatergic and GABAergic neurons occurs in associative memory.

Contextual effects in sensorimotor adaptation adhere to associative learning rules

eLife, 2022
Traditional associative learning tasks focus on the formation of associations between salient events and arbitrary stimuli that predict those events. This is exemplified in cerebellar-dependent delay eyeblink conditioning, where arbitrary cues such as a ...

High-throughput automated methods for classical and operant conditioning of Drosophila larvae

eLife, 2022
Learning which stimuli (classical conditioning) or which actions (operant conditioning) predict rewards or punishments can improve chances of survival.

Pavlov's dog associative learning demonstrated on synaptic-like organic transistors [PDF]

, 2013
In this letter, we present an original demonstration of an associative learning neural network inspired by the famous Pavlov's dogs experiment. A single nanoparticle organic memory field effect transistor (NOMFET) is used to implement each synapse.

Dopamine transients do not act as model-free prediction errors during associative learning

Nature Communications, 2020
Dopamine neurons are proposed to signal the reward prediction error in model-free reinforcement learning algorithms. Here, the authors show that when given during an associative learning task, optogenetic activation of dopamine neurons causes associative,

The company that words keep: comparing the statistical structure of child- versus adult-directed language [PDF]

, 2013
Does child-directed language differ from adult-directed language in ways that might facilitate word learning? Associative structure (the probability that a word appears with its free associates), contextual diversity, word repetitions and frequency were ...

Training on multiple days results in better learning in embedded eyeblink conditioning in young human adults

npj Science of Learning
Eyeblink conditioning is mediated by similar cerebellar pathways in humans and animals and is typically investigated using delay or trace protocols. These studies show that humans can easily acquire eyeblink conditioning within a single day of training ...

Pictorial Referents Facilitate Recognition and Retrieval Speeds of Associations Between Novel Words in a Second Language (L2) and Referents

Frontiers in Communication, 2021
This study reveals associative processes for novel words in a second language (L2) and their referents. Thirty Japanese participants learned associative pairs for novel words in Chinese and pictorial referents (CP), as well as novel words in Chinese and ...

Self-organized learning in multi-layer networks [PDF]

, 2010
We present a framework for the self-organized formation of high level learning by a statistical preprocessing of features. The paper focuses first on the formation of the features in the context of layers of feature processing units as a kind of resource-
