Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon, literally "borer, auger"), is a surgical intervention in which a hole is drilled into the human skull. (Source: wikipedia)
This technique is believed can bring out the maximum potential of the human brain such as; super memory, telekinesis, ability of 6th sense/supernatural phenomenon and precognition.

*disclaimer: (especially for children under 13th) this is just fiction, trepanation is real but the rest is not, so don't believe on what internet says. Don't want to see someone reported on tech support channels about this. lol
