Synaptic potentiation has been linked to learning in sensory cortex, but the connection between this potentiation and increased sensory-evoked neural activity is not clear. Here, we used longitudinal in vivo Ca2+ imaging in the barrel corte...
Multiple changes in connectivity between buccal ganglia mechanoafferents and motor neurons with different functions after learning that food is inedible in Aplysia [0.03%]
阿氏海兔在学习食物不可食之后，唇脑神经元与执行不同功能的运动神经元之间连接性的多次改变

Itay Hurwitz et al.
Changes caused by learning that a food is inedible in Aplysia were examined for fast and slow synaptic connections from the buccal ganglia S1 cluster of mechanoafferents to five followers, in response to repeated stimulus trains. Learning a...
Repeated stimulation of feeding mechanoafferents in Aplysia generates responses consistent with the release of food [0.03%]

How does repeated stimulation of mechanoafferents affect feeding motor neurons? Monosynaptic connections from a mechanoafferent population in the Aplysia buccal ganglia to five motor followers with different functions were examined during r...
Skewing information flow through pre- and postsynaptic plasticity in the mushroom bodies of Drosophila [0.03%]

Animal brains need to store information to construct a representation of their environment. Knowledge of what happened in the past allows both vertebrates and invertebrates to predict future outcomes by recalling previous experience. Althou...

The common fruit fly Drosophila melanogaster provides a powerful platform to investigate the genetic, molecular, cellular, and neural circuit mechanisms of behavior. Research in this model system has shed light on multiple aspects of brain ...
The caloric value of food intake structurally adjusts a neuronal mushroom body circuit mediating olfactory learning in Drosophila [0.03%]
卡路里值通过结构上调节神经蘑菇体回路来调控果蝇的嗅觉学习效应

Associative learning enables the adaptive adjustment of behavioral decisions based on acquired, predicted outcomes. The valence of what is learned is influenced not only by the learned stimuli and their temporal relations, but also by prior...
Reinforcement expectation in the honeybee (Apis mellifera): Can downshifts in reinforcement show conditioned inhibition? [0.03%]
蜜蜂的强化预期（Apis mellifera）：强化下降能表现出条件抑制作用吗？

When animals learn the association of a conditioned stimulus (CS) with an unconditioned stimulus (US), later presentation of the CS invokes a representation of the US. When the expected US fails to occur, theoretical accounts predict that c...
What do the mushroom bodies do for the insect brain? Twenty-five years of progress [0.03%]

In 1998, a special edition of Learning & Memory was published with a discrete focus of synthesizing the state of the field to provide an overview of the function of the insect mushroom body. While molecular neuroscience and optical imaging ...
Sensory encoding and memory in the mushroom body: signals, noise, and variability [0.03%]
