Direct neural resequencing
Direct neural resequencing was a medical procedure used during the 24th century to increase neural activity and stabilize synaptic functions. It was generally used in conjunction with cortical stimulation when a patient did not respond to cordrazine.

In 2375, the Silver Blood Torres was on her deathbed, and failed to respond to an iso-synaptic pulse initiated from a cortical stimulator, the Tom Paris suggested direct neural resequencing as a last ditch effort to revive her, but The Doctor told him that she was already gone. ()

The Doctor used this procedure on B'Elanna Torres in 2376, to revive her from a coma. ()
