Parvalbumin-containing inhibitory neurons are crucial for expression of plasticity in adult visual cortex that supports visual recognition memory, but not for expression of ocular dominance plasticity that results from monocular deprivation.
Measures of visuocortical activity during aversive generalization learning revealed sharpened representations of facial identity, reflecting inhibitory interactions between neuronal populations that represent facial features associated with threat versus safety.

Complex and distributed plasticity processes are revealed by a functional and pharmacological analysis of visual habituation learning in larval zebrafish.

Inhibitory synaptic plasticity provides a flexible and biologically plausible circuit mechanism to detect the novelty of bottom-up stimuli and to generate stimulus-specific adaptation.

Multivariate analyses of human electrophysiological recordings revealed that the brain represents unexpected visual stimuli with greater fidelity than expected stimuli which arose independently of simple habituation arising from repetition.
The superior colliculus reveals hallmarks of sophisticated visual computation, including selectivity, invariance, and stimulus-specific habituation to behaviorally relevant stimuli.
Activity levels in anterior and posterior cholinergic basal forebrain neurons are associated with distinct aspects of global brain state, sensory salience, reward expectation, and aversive reinforcement learning.
Mice that viewed a visual stimulus whilst running showed recovery of the neuronal responses that had been lost due to early visual deprivation, with potential relevance for amblyopia.

Light-seeking strategies in Zebrafish larvae are dissected using a virtual-reality assay, and these data are used to establish minimal stochastic and neural-circuits models that quantitatively capture this behavior.
Neurons in the mouse superior colliculus comprise about 20 types based on their responses to visual stimuli, and neurons of the same type tend to cluster together.
