Your cerebral cortex has been enhanced with the Logic Co-Processor, increasing your Intelligence by 1.— In-game description

The Logic Co-Processor Intelligence Implant is an implant perk in Fallout: New Vegas.


This implant, called the logic co-processor, can be bought from Doctor Usanagi at the New Vegas medical clinic and increases the player character's Intelligence by one. The bonus from this implant will increase the number of skill points that are gained per level. The additional Intelligence point grants an additional skill point only at every other level.


If one's Intelligence is less than 4, Doctor Usanagi will take pity on the Courier and offer a discount of 1000 caps for this implant. This is similar to an interaction with Dr. Lorri in Fallout who offered implants and would offer the intelligence implant at a significant discount.

Once the effects wears off, the intelligence implant will be for sale again. player.setav intelligence 3 corrects this. [verified]
