var/extended_desc = "Development of Man-Machine Interfaces can be dated all the way back to the late 20th century within the Sol system, but the first viable designs didn't emerge until 2408 when Zeng-Hu Pharmaceuticals and Bishop Cybernetics unveiled a co-developed unit and established dominance over the niche market that persists into the present day. \
The brain is submerged in a preservation fluid rich in mannitol, mitocholide, dissolved oxygen (or functional equivalent in other species) as well as a carefully tuned mixture of nutrients, hormones, peptides, and various other essential substances produced by a specialised chemical synthesiser. \
A non-invasive neural interface uses a combination of targeted magnetic pulses, micro-electric discharges, and a grid of highly sensitive EMF probes allow a two-way connection between the MMI and the brain. On-board microphones, cameras, and a speaker provide basic sensory input and a method of communication, which can be expanded with an optional radio upgrade. Any further functionality must be provided by whatever the MMI is installed into. \
Brains housed inside an MMI are effectively biologically immortal, provided the unit remains powered."

Whilst these specialty MMIs are rarely used owing to the far greater applicability and convenience of the mindslave implant, they do see occasional employment by undercover agents that wish to stealthily convert the AI-slaved cyborgs of Nanotrasen. \
