Hemodynamic behavioral and biochemical disturbances induced by an experimental cranio-cervical injury (whiplash) in rats

Abstract Two days after an experimental whiplash performed on anesthetized Long—Evans female rats, without any direct blow to the head, we observed: (1) a hypotension (in supine position) ( P P P These results are in agreement with the hypothesis that a change in brain amines metabolism could explain the different functional effects of whiplash. We therefore believe that the postconcussion syndrome is not subjective and that the neck injury is primary in the determination of the syndrome.
