Study: Zebrafish are smarter than we thought

A new study from MIT and Harvard University suggests that the brains of the seemingly simple zebrafish are more sophisticated than previously thought. The researchers found that larval zebrafish can use visual information ...

Neuroscientists explore the risky business of self-preservation

A critical survival decision for all animals is when, where and how to escape from a looming threat. A Northwestern University research team using multi-neuron imaging has learned that the escape response for prey is more ...

Painkillers relieve zebrafish larvae discomfort

Lynne Sneddon is a myth buster. Having debunked the fisherman's legend that fish don't feel pain, Sneddon, from the University of Liverpool, UK, has become a leading figure in the movement to reduce, replace and refine the ...

Scientists reveal how animals find their way 'in the dark'

Scientists have revealed the brain activity in animals that helps them find food and other vital resources in unfamiliar environments where there are no cues, such as lights and sounds, to guide them.

Fish brains help explain human sensory perception

Advanced calcium imaging of zebrafish brains is helping University of Queensland researchers discover how sensory stimuli such as sights and sounds are integrated in the human brain.

New insights into how vascular networks form in fish brains

How the intricate network of blood vessels forms within the brain has long fascinated biologists. Though the human brain comprises only 2 percent of body weight it receives up to 15 percent of the cardiac output through this ...
