Why do bats fly into walls?

Bats excel in acoustic perception and detect objects as tiny as mosquitoes using sound waves. Echolocation permits them to calculate the three-dimensional location of both small and large objects, perceiving their shape, size and texture. To this end, a bat’s brain processes various acoustic dimensions from the echoes returning from the object such as frequency, […]

Repulsion mechanism between neurons governs fly brain structure

Researchers at Kanazawa University report in Nature Communications the discovery that in the developing fly brain, neurons stemming from the same parent cell experience repulsion. This lineage-dependent repulsion is regulated by a protein known as Dscam1. Figure 1. Dscam regulates lineage-dependent repulsion. Neurons of the same lineage repel each other and project to different columns […]
