Exhibit in Voyager museum

A neurocortical monitor, sometimes shortened to cortical monitor, was a small tricorder sensor used to record a complete encephalographic profile by tracking and recording a patient's neural functions. Among the things it could detect were peptide readings. It was placed on the parietal bone and could be programmed to send an alert to sickbay if it detected any unusual neurological activity.

In 2373 aboard the USS Voyager, The Doctor had Lieutenant Tuvok wear a neurocortical monitor in order to record a complete encephalographic profile if he had another episode related to his mental breakdown. (VOY: "Flashback")

Later that year, Ensign Vorik wore a cortical monitor while The Doctor was trying to treat his pon farr. (VOY: "Blood Fever")

In 2375, The Doctor used a cortical monitor on Chakotay when he was experiencing hallucinations caused by chaotic space. (VOY: "The Fight")

In 2377, after Seven of Nine began having disconcerting dreams about Unimatrix Zero, The Doctor gave her a cortical monitor to track her REM cycles. (VOY: "Unimatrix Zero") He also had her wear one later that year, when her cortical node was malfunctioning, as an alternative to remaining under observation in sickbay. (VOY: "Imperfection")

As Voyager was being prepared as a museum ship in 2381, a cortical monitor (and larger-scale model) were part of a display in sickbay. (LD: "Twovix")

In the 2013 alternate reality-set video game Star Trek, a neurocortical monitor is one of the items available to scan. Montgomery Scott recalls once wearing one as a child to determine the cause of his headaches, only to be teased by the other children.
