From the article:

“A review of brain imaging studies found that handwriting activates a broader network of neural pathways than typing or tapping, engaging fine motor skills, memory encoding, and deeper cognitive processing simultaneously. The physical act of forming letters on paper recruits brain regions that digital input simply doesn’t reach. Studies suggest that the pen engages what some researchers describe as a “symphony of neural pathways,” connecting motor control to thought formation in ways that keyboards and touchscreens may bypass.”
