can anyone explain this better: I just don't understand the bradycardia part?

If intracranial pressure is rapidly elevated, cerebral blood flow is reduced. The increase in intracranial pressure stimulates the vasomotor center and produces an increase of systemic blood pressure that may lead to a restoration of cerebral blood flow (Cushing response). A profound bradycardia is also associated with this response.

In this situation both sympathetic and prasym are stimulated
sym overactivity causes the BP to increse and ps overactivity causes the bradycardia because heart is innervated mostly by ps and vasculature are innervated by sym

so the vasomotor center stimulates both with an increase in intracranial pressure.
