# String theory and the wave function

I didn't find an article about this so I'll ask it here:

How does the quantum mechanical wave function of a particle arise in ST?

Sorry if it has been asked before, but I couldn't find a topic about it.

In string theory, the quantum state can be represented as a functional
$$\Psi[X(\sigma)]$$
In the pointlike limit you can ignore the dependence on \sigma, so what remains is a wave function
$$\Psi(X)$$
