The blastoneurons were a type of neural parasites, a dangerous lifeform of undetermined origin. They were roughly disc shaped, and anatomically resembled a single large brain cell. They were capable of individual flight, but most commonly attached themselves to humanoid hosts, via a "stinger" which tapped into the nervous system—for example, through the spinal cord. This allowed control over the host, though it also caused severe pain and madness.

These parasites were believed to have traveled from the Beta Portolan system to Levinius V, then Theta Cygni XII, and in 2265, Ingraham B. By 2267 they had reached Deneva, where they were encountered by the crew of the USS Enterprise. The crew of that ship discovered that the parasites, which were impervious to most environmental factors including high temperature and radiation, were vulnerable to high-intensity visible and ultraviolet light, and were able to eradicate them by placing a series of UV light-producing satellites in Denevan orbit. (TOS episode: "Operation -- Annihilate!")

In an alternate timeline, the blastoneurons had taken on a more gelatinous form, pink in color, and primarily encased the cranium of a victim. In this timeline, the creatures reached Deneva in the year 2258. (TOS - Operation: Annihilate comic: "Part 1")
