Discovery of the neural circuit for fear conditioning of fish

Animals are often noted sensing signs of danger and reacting. A simple form of this phenomenon is called fear conditioning, which is a type of learning commonly seen in every animal. By manipulating the activity of specific ...

New research tool targets microRNA expression in zebrafish

A new research tool for studying microRNA expression in zebrafish will help researchers study the effects of miRNA on the early development of this model organism and better understand developmental and disease mechanisms ...

'Census' in the zebrafish's brain

The zebrafish is a master of regeneration: If brain cells are lost due to injury or disease, it can simply reproduce them—contrary to humans, where this only happens in the fetal stage. However, the zebrafish is evolutionarily ...

Social experiences impact zebrafish from an early age

It is commonly said that childhood experiences shape adult behavior; that events that we may not even remember can have long-lasting or even permanent effects. In a new article by scientists at the Champalimaud Center for ...

This nasal receptor mediates the appetizing smell of fish food

The aquatic environment is full of tantalizing chemicals that can guide a fish to mates or meals. Now, scientists in Japan have identified the olfactory receptor and brain circuitry that picks up the scent of adenosine triphosphate, ...

Flaws emerge in modeling human genetic diseases in animals

My lab, based at the University of Southern California Keck School of Medicine, uses zebrafish to model human birth defects affecting the face. When I tell people this, they are often skeptical that fish biology has any relevance ...
