Abstract
Zebrafish (Danio rerio) are becoming increasingly popular in neurobehavioral research. Here, we summarize recent data on behavioral responses of adult zebrafish to a wide spectrum of putative anxiolytic and anxiogenic agents. Using the novel tank test as a sensitive and efficient behavioral assay, zebrafish anxiety-like behavior can be bi-directionally modulated by drugs affecting the gamma-aminobutyric acid, monoaminergic, cholinergic, glutamatergic and opioidergic systems. Complementing human and rodent data, zebrafish drug-evoked phenotypes obtained in this test support this species as a useful model for neurobehavioral and psychopharmacological research.

Zebrafish models for translational neuroscience research: from tank to bedside.

TL;DR: The Zebrafish is emerging as a new important species for studying mechanisms of brain function and dysfunction and the potential of zebrafish models in behavioral phenomics and high-throughput genetic/small molecule screening, which is critical for CNS drug discovery and identifying novel candidate genes.

Modeling anxiety using adult zebrafish: A conceptual review

TL;DR: This work evaluates established and novel approaches to uncover the molecular substrates, genetic pathways and neural circuits of anxiety using adult zebrafish, and provides a conceptual framework for the wider application of zebra fish and other aquatic models in anxiety research.

Measuring thigmotaxis in larval zebrafish.

TL;DR: It is suggested that stimuli such as exposure to sudden darkness could be used proficiently to trigger the expression of anxiety-like behaviors in laboratory settings and is constituting a valuable tool for stress and central nervous system research as well as for preclinical drug screening and discovery.

A two-dimensional neuropsychology of defense: fear/anxiety and defensive distance

TL;DR: A picture of the neural systems controlling defense that updates and simplifies Gray's "Neuropsychology of Anxiety" is presented, based on two behavioural dimensions: 'def defensive distance' as defined by the Blanchards and 'defensive direction'.

Understanding behavioral and physiological phenotypes of stress and anxiety in zebrafish

TL;DR: Zebrafish models of stress by analyzing how environmental and pharmacological manipulations affect their behavioral and physiological phenotypes are validated and alterations in whole-body cortisol levels in zebrafish parallel behavioral indices of anxiety are shown.

Neurocognitive mechanisms of anxiety: an integrative account

TL;DR: Neuroimaging studies of conditioned fear, attention to threat and interpretation of emotionally ambiguous stimuli indicate common amygdala-prefrontal circuitry underlying these processes, and suggest that the balance of activity within this circuitry is altered in anxiety, creating a bias towards threat-related responses.

Zebrafish Behavioral Profiling Links Drugs to Biological Targets and Rest/Wake Regulation

TL;DR: The development and application of a high-throughput, quantitative screen for drugs that alter the behavior of larval zebrafish are reported and it is found that the multidimensional nature of observed phenotypes enabled the hierarchical clustering of molecules according to shared behaviors.
