The physics of brain development: How cells pull together to form the neural tube

Phys · · 573 words · By Georgia Institute

Georgia Tech physicists, collaborating with UCL researchers, have used computer modeling to explain the physical mechanisms behind neural tube closure during early development. The research identified that actin proteins forming a 'purse string' around the opening, coupled with molecular motor tension, drives the necessary closure. The findings suggest this physics-based modeling approach can be applied to understand other complex biological processes.
