Here’s how animals find their way in the dark
Ever wondered how animals find their way in the dark? US scientists have revealed that their brain activity helps them find food and other vital resources in unfamiliar environments where there are no clues such as lights and sounds to guide them.
New York: Ever wondered how animals find their way in the dark? US scientists have revealed that their brain activity helps them find food and other vital resources in unfamiliar environments where there are no clues such as lights and sounds to guide them.
Animals that are placed in such environments display spontaneous, seemingly random behaviours when foraging. While these behaviours have been observed in many organisms, the brain activity behind them has remained elusive due to difficulties in knowing where to look for neural signals in large vertebrate brains.
The study conducted in larval zebra fish, the team analysed the relationship between spontaneous brain activity and spontaneous behaviour. They generated whole-brain activity maps of neuronal structures that correlated with the patterns in the animals' movements.
