Perhaps the crew carry out an experiment and use this on the dead Jockeys brain?
"WEYLAND INDUSTRIES SYNAPSE REESTABLISHER"
"Another remarkable technological feat from Weyland scientists, the Synapse Reestablisher, through precise, minute electrical innervation, awakens dormant neurons in the brain tissue of deceased or dying patients. This delicate technology is highly sensitive and restricted to a select group of doctors and scientists. The 9 existing Reestablishers have been in use for the past 2 years in medical schools and biotech research centers for experimental use only, pending FDA investigation."
Imagine a scene of a dead jockey head coming back to life, it would be completley disturbing and at the same time echo the Ash reanimation scene from Alien, before an adverse reaction of sorts causes the brain to explode?
Probs just my f**ked up imagination in overdrive tho
