I thought we're past the times when we thought cartilage, neurons, and other tissues cannot regenerate. Didn't we, for example, find that BDNF activators can trigger neurogenesis?

How do you create a well-connected motor neuron with a 3-foot or one-meter-long axon? Or brain neurons that are highly connected to other areas?

I would appreciate any pointers to a scientific article that describes this.

Peripheral neurons can regenerate [0]. Heart muscle also can repair through other factors [1].
