Vocal learning promotes patterned inhibitory connectivity [PDF]
Nature Communications, 2017 Complex motor behaviors such as birdsong are learned through practice and are thought to depend on specific excitatory connectivity in premotor circuits.

Stability and learning in excitatory synapses by nonlinear inhibitory plasticity
PLoS Computational Biology, 2022 Synaptic changes are hypothesized to underlie learning and memory formation in the brain. But Hebbian synaptic plasticity of excitatory synapses on its own is unstable, leading to either unlimited growth of synaptic strengths or silencing of neuronal ...

Learning excitatory-inhibitory neuronal assemblies in recurrent networks [PDF]
eLife, 2021 Understanding the connectivity observed in the brain and how it emerges from local plasticity rules is a grand challenge in modern neuroscience. In the primary visual cortex (V1) of mice, synapses between excitatory pyramidal neurons and inhibitory ...

The Inhibitory Mechanism in Learning Ambiguous Words in a Second Language [PDF]
Frontiers in Psychology, 2017 Ambiguous words are hard to learn, yet little is known about what causes this difficulty. The current study aimed to investigate the relationship between the representations of new and prior meanings of ambiguous words in second language (L2) learning ...

Learning-induced remodelling of inhibitory synapses in the motor cortex
Open BiologyRobust structural and functional plasticity occurs at excitatory synapses in the motor cortex in response to learning. It is well established that local spinogenesis and the subsequent maintenance of newly formed spines are crucial for motor learning ...

Inhibitory learning is modulated by nicotinic acetylcholine receptors. [PDF]
Neuropharmacology, 2015 Prior research has established that stimulating nicotinic acetylcholine receptors can facilitate learning and memory. However, most studies have focused on learning to emit a particular behavior, while little is known about the effects of nicotine on learning to withhold a behavioral response.

Inhibitory learning of phototaxis by honeybees in a passive-avoidance task. [PDF]
Learn Mem, 2019 Honeybees are a standard model for the study of appetitive learning and memory. Yet, fewer attempts have been performed to characterize aversive learning and memory in this insect and uncover its molecular underpinnings. Here, we took advantage of the positive phototactic behavior of bees kept away from the hive in a dark environment and established a ...

Inhibitory Circuits in the Basolateral Amygdala in Aversive Learning and Memory [PDF]
Frontiers in Neural Circuits, 2021 Neural circuits in the basolateral amygdala (BLA) play a pivotal role in the learning and memory formation, and processing of emotionally salient experiences, particularly aversive ones. A diverse population of GABAergic neurons present in the BLA orchestrate local circuits to mediate emotional memory functions.

Early Sensory Deprivation Leads to Differential Inhibitory Changes in the Striatum During Learning
Frontiers in Neural Circuits, 2021 The corticostriatal circuit has been identified as a vital pathway for associative learning. However, how learning is implemented when the sensory striatum is permanently impaired remains unclear.
