Wired reflexes? Yeah, that's old-school. We're talking rewiring the higher nervous system here. Brainware Upgrades!

These enhancements involve adding additional hardware and wetware to the human brain, augmenting memory and acuity functions as well as faster data transmission from one part of the brain to another. Neurological rebuilding is the result of applying the speedware neurological enhancement concepts directly to the brain and tapping into many more functions than motor response.

Neurological rebuilding is rated by “stage”. Each of the first three stages of neurological rebuilding is significantly more intrusive into the natural grey matter of the brain than the previous level, rechanneling neuron trunks and overlaying nanoneural pathways into the brain. The later stages of neurological rebuilding add nanoenhancements to even the minor neural pathways, and provide major upgrades to memory and concentration centres.

Neural Rebuilding can be quite psychologically damaging, as the owner of a rewired brain is often unsure whether he would have been able to think or do the things he does now, and psychoses involving the belief that the cybernetics themselves have taken over the cyborg’s life are not that unusual.

Each stage of neural rebuilding provides the following bonuses:
+ (Stage) on all Intelligence skill checks.
+ (Stage / 2) on all Tech skill checks.
- (Stage x 2) on IP costs for improving a skill (half this bonus if using 5 IP / level instead of the standard 10 IP / level in CP2020).

Stage 1 Neural Rebuilding – $2,000 – N – 2d6
Stage 2 Neural Rebuilding – $5,000 – M – 3d6
Stage 3 Neural Rebuilding – $12,500 – MA – 4d6
Stage 4 Neural Rebuilding – $30,000 – CR – 5d6
Stage 5 Neural Rebuilding – $75,000 – CR – 6d6
Stage 6 Neural Rebuilding – $200,000 – CR – 7d6

In addition to Neural Rebuilding, some companies also attach a limited-function math computer to the enhanced grey matter. In this way, the brain has access to significantly enhanced mathematic capabilities. A math subprocessor is rated by stage, and provides a skill level of 3 times the stage of the unit on all math skill checks. Further, because these advanced mathematics are routinely running as a background function, the owner can use this math skill as a complementary skill for skill checks where access to higher math could be of immediate help (such as when playing pool or calculating the exact date of the beginning of the universe). Thus, a stage 2 math subprocessor would provide a +2 bonus when used in this way.

Stage 1 Math Subprocessor – $300 – N – 1
Stage 2 Math Subprocessor – $1,000 – N – 1d2+1
Stage 3 Math Subprocessor – $3,000 – N – 1d3+1

The following are some of the various neural rebuilding packages available in the current market.

BaurMaat Cranial Rebuild
    BaurMaat’s Cranial Rebuild package is a complete rebuild of the subject’s brain and skull. Recipients of this package have portions of the skull removed, enhancements added to the brain and skull itself, and then have a nanofactory rebuilt and restructured skull force-grown to replace the missing portions in a matter of days.
    The result is a tougher, harder skull that is designed to handle much stronger impacts with minimal damage to the skull’s contents when compared to a standard human skull, which in turn contains a vastly enhanced computing centre linked to the brain. This is treated as skull reinforcing (head hits do only normal damage), as well as a Stage 3 Neural Rebuild paired with a Stage 1 Math Subprocessor.
    $13,700 – CR – 5d6 HL

BaurMaat Advanced Cranial Rebuild
    The advanced cranial rebuild from BaurMaat takes the basic Cranial Rebuilding and adds state of the art neurological enhancements, a top of the line math subprocessing unit, and protects it under enhanced armouring of the skull. This provides Stage 5 Neurological Rebuilding, a Stage 3 Math Subprocessor, Skull Reinforcing (normal damage from head hits) and SP 6 Skull Armour (Awareness diff 30 to notice).
    $79,450 – CR – 9d6 HL

Genesis Alpha Neural Enhancement
    This is the very simplest neural enhancement, relying on nanotech to rewire the brain without direct surgical contact with the subject’s grey matter. This provides standard Stage 1 Neurological Rebuilding.
    $2,000 – N – 2d6 HL

Genesis Bravo Neural Enhancement
    The Genesis Bravo package is the most common neurological rebuild on the market. It involves minor surgery to implant enhanced processors into the brain along with the nanotech required to link them to the rest of the subject’s grey matter and nervous system. This provides standard Stage 2 Neurological Rebuilding along with the beginnings of ambidexterity (reducing off-hand penalties by 1 point).
    $5,500 – M – 4d6 HL

Genesis Savant Neural Enhancement
    The Genesis Savant was considered to be the top of the line neurological enhancement until the BaurMaat Advanced Cranial Rebuilding was released (and because most people are unaware of the Genesis Oracle). This is a Stage 4 Neurological Rebuilding paired with full ambidexterity, and also provides the equivalent of a Kerenzikov Reflex boost (+1 Reflex).
    $31,100 – CR – 8d6 HL

Genesis Oracle Neural Enhancement
    The Oracle Enhancement package is Genesis’ latest and most secretive enhancement package for the human brain, and is by all accounts the most potent upgrade available – even though it is incredibly rare and a fairly well-protected secret. It is typically installed into high-end military and legal netjocks. It completely rewires the human brain and nervous system to previously unheard of levels. The end result is a Stage 6 Neurological Rebuilding, full ambidexterity, and a boostmastered Kerenzikov reflex boost (+3 Reflex).
