A new study in Laterality investigated the relationship between neuroanatomical or behavioural lateralization and anxiety using a light-dark preference test in adult zebrafish.

A new study in symmetry suggests that the behaviour exhibited in a test measuring brain lateralization is predictive of the side bias exhibited by zebrafish in a 2-choice discrimination task. Lateralized individuals tended to turn to a preferred side of the experimental tank regardless of extensive training, making it difficult to understand whether these individuals have the cognitive abilities to solve the task.

A new study on bioRxiv suggests that working memory and exploration-search strategy changes are both impaired in aged zebrafish. Acute exposure to a selective dopamine D1/D5 receptor partial agonist, enhanced working memory in aging, but had no detectable effect on behavioural flexibility.

A new memory task (the FMP Y-maze), designed by researchers at the University of Portsmouth, enables investigation of working memory and search strategies in both vertebrates and invertebrates.

Caffeine and Sildenafil alter attention levels and impulsivity but not learning in zebrafish suggests a new study published in the journal, European Neuropsychopharmacology.

The learning skills of zebrafish in a Skinner box may not effected by brain lateralization nor anxiety-like behaviour according to findings published in symmetry.
