Song learning and plasticity in songbirds
Current Opinion in Neurobiology, 2021Birdsong provides a fascinating system to study both behavioral and neural plasticity. Oscine songbirds learn to sing, exhibiting behavioral plasticity both during and after the song-learning process. As a bird learns, its song progresses from a plastic and highly variable vocalization into a more stereotyped, crystallized song.

Basic mechanisms of plasticity and learning
2022The last century was characterized by a significant scientific effort aimed at unveiling the neurobiological basis of learning and memory. Thanks to the characterization of the mechanisms regulating the long-term changes of neuronal synaptic connections, it was possible to understand how specific neural networks shape themselves during the acquisition ...

Learning and synaptic plasticity
Behavioral and Brain Sciences, 1997Controversy surrounds several experiments that have addressed whether selective synaptic strengthening occurs during learning. To date, the evidence suggests that widespread alterations in synaptic strength, through either kindling or electroconvulsive shock, can disrupt this hypothetical process. The lack of evidence for selective modification of

Learning, aging and intrinsic neuronal plasticity
Trends in Neurosciences, 2006In vitro experiments indicate that intrinsic neuronal excitability, as evidenced by changes in the post-burst afterhyperpolarization (AHP) and spike-frequency accommodation, is altered during learning and normal aging in the brain. Here we review these studies, highlighting two consistent findings: (i) that AHP and accommodation are reduced in ...

Music and Learning‐Induced Cortical Plasticity
Annals of the New York Academy of Sciences, 2003Abstract: Auditory stimuli are encoded by frequency‐tuned neurons in the auditory cortex. There are a number of tonotopic maps, indicating that there are multiple representations, as in a mosaic. However, the cortical organization is not fixed due to the brain's capacity to adapt to current requirements of the environment.

Synaptic plasticity in the red nucleus and learning
Behavioural Brain Research, 1988Pairing of the stimulus to the cerebral peduncle (CP) with that to the forearm skin leads cats to flex their forearms within a 10-day training period in response to stimulus to CP, which was initially ineffective. Behavioral study and extracellular unit analysis suggested that the cellular mechanism for this conditioning lies at the corticorubral (CR ...

An Embodied Model of Learning, Plasticity, and Reward
Adaptive Behavior, 2002We describe and discuss a neural network model of the dopaminergic system based on observed anatomical and physiological properties of the primate midbrain. The model relies on value-dependent synaptic modification to acquire temporal information regarding reward-related events and the stimuli with which such events are paired.
