Why blind bats never collide while flying at night

Washington: A new study shows that bats emit “echolocation sounds” and are equipped with a spatial map which helps them figure echo delays and relate it to the external factors. 

The study conducted by Technische Universitat Munchen (TUM) examined that the number of activated neurons in bats’ brain increased when they flew too close to an object.

The map is similar to the navigation systems used in cars. It shows bats the terrain in which they were moving. 

The major difference is that the bats’ inbuilt system warns them of an impending collision by enhancing neuronal signals for objects that are in close proximity.

The results show that the nerve cells interpret the bats’ rapid responses to external stimuli by enlarging the active area in the brain to display important information.
