Fish Behavior as a Neural Proxy to Reveal Physiological States

Abstract

Behaviors are the integrative outcomes of the nervous system, which senses and responds to the internal physiological status and external stimuli. Teleosts are aquatic organisms which are more easily affected by the surrounding environment compared to terrestrial animals. To date, behavioral tests have been widely used to assess potential environmental risks using fish as model animals. In this review, we summarized recent studies regarding the effects of internal and external stimuli on fish behaviors. We concluded that behaviors reflect environmental and physiological changes, which have possible implications for environmental and physiological assessments.

Dysfunction of Prkcaa Links Social Behavior Defects with Disturbed Circadian Rhythm in Zebrafish

“…The alterations of fish behavior are intimately related to structural and functional changes in the nervous system [ 28 , 29 ]. To investigate the effects of the prkcaa mutation on the expression of genes involved in neural processes, the full GO term list for the DEGs between the 3145A_M and WT_M samples were checked to identify the terms associated with processes such as nervous system development, neuron differentiation and calcium signaling.…”
