Neurotechnology is the branch of technology dealing with technological augmentation to the nervous system of a biological sophont or other living creature. These augmentations often take the form of interfacing between the neurons of the subject and an external system of processors, or with external sensors and data receiving devices. In most cases the interface devices and at least some of the processing substrate are located inside the body of the subject; many users prefer to have no obvious signs of augmentation outside their body, although others accept (or even prefer) visible additions to their bodyplan.

Among the first applications of neurotechnology, developed during the Information Age and Early Interplanetary age, were neuroprosthetics; devices intended to replace a motor, sensory or cognitive capacity that have been damaged as a result of an injury or a disease. Visual or auditory prosthetics and a wide range of mobility devices were linked to and controlled by the nervous system of the user, and over time these applications became better than the natural capabilities of the human body.

Meanwhile a number of neural interfaces became available for users who were not impaired, including brain-computer interfaces that developed into Direct Neural Interface technology. As artificial intelligence improved in this period, a range of external AI applications became available, which could act as personal assistants and advisors to the user. The increasing sophistication of the linkage between these applications and the user's mind eventually allowed the development of a so-called exoself; a system so intimately linked to the user that it became part of their consciousness.

Bioneurotechnology

Many augmentations to the nervous system consist of biological or synanotech devices, generally well-integrated so that they become a part of the user's body. Somatic improvements to the nerves and other cells in the central nervous system allow faster processing and information flows, as well as faster reflexes, improved cognition and a range of new capacities not possessed by baseline humans. Many somatic genetic augmentations to the nervous system are designed to improve the interface route between internal and external processors; often a user's body will react against pure hylotech implants whereas they will tolerate biotech more readily.

Neurotechnological provolution

As well as genetic engineering, neurotechnology has an important role to play in the process of raising non-sophont organisms towards sentience. Early efforts to provolve dogs included direct neural interfacing between the animals and their masters, allowing a two-way flow of information that eventually became an ability to use complex language. Similar augmentics assisted early elephant and cephalopod provolution attempts. In more recent milllenia, the role of biological/information interfacing has allowed the provolution of many diverse species, including plants an a wide variety of xenobiota.

    Common device used by those who can't afford good tasting food. It is a nanotech dose that coats the throat, palate, teeth and tongue to simulate the texture and flavor of a preferred food. It is usually available in week-long doses, but permanent implants are also available for an increased cost.
  • Mindhacker - Text by John B
    Illegal profession in many if not most clades or polities. Specializes in extracting information from the mental processes of a target sophont. The best mindhackers can extract full information replicas without the target recognizing this, but that is exceedingly rare without a transapient intellectual rating. Mindworker profession.
