We re-examine quantization via branes with the goal of understanding its relation to geometric quantization. If a symplectic manifold M can be quantized in geometric quantization using a polarization \mathcal P, and in brane quantization using a complexification Y, then the two quantizations agree if \mathcal P can be analytically continued to a holomorphic polarization of Y. We also show, roughly, that the automorphism group of M that is realized as a group of symmetries in brane quantization of M is the group of symplectomorphisms of M that can be analytically continued to holomorphic symplectomorphisms of Y. We describe from the point of view of brane quantization several examples in which geometric quantization with different polarizations gives equivalent results.
