The simple action is that your brain moves backwards/forwards within your skull as it reverberates in response to the impact. This causes twisting/flexion/extension in the brainstem (of the reticular activating system). The reticular activating system is what regulates wakefulness/consciousness. It is not due to lack of blood supply.
If you want a more detailed answer...see the reference.
