Invasive BCIs Edit outline

This section needs more about the advantages and disadvantages of invasive BCIs and what they are invading. In general, this section and its subsections of "vision" and "movement" need to be edited and rearranged. There are a bunch of sentences that are out of place and don't contribute to the narrative or argument in their current position.

My contribution:

Explain why BCIs need to be inserted surgically and why the cortex is important for signal gathering.


 * The cortex is where almost all higher level thinking occurs
 * The cortex is on the surface and relatively easy to access
 * Intercortical arrays provide better temporal and spatial resolution

Expand the trauma problem


 * How scar tissue for forms around the probes
 * Protein sheath formation
 * Signal loss and timeline from Blackrock
 * How flexible arrays can help

Invasive BCIs

Although invasive BCIs surgery to implant them, they offer some tempting advantages to non-invasive BCIs, mainly greater spatial and temporal resolution. When measuring neural activity noninvasively, the skull and meninges of the brain act as capacitive material, adding noise and dampening the neural signals. Therefore, a noninvasive BCI must measure over a relatively large area of the skull and integrate over a longer time period to acquire usable signals. By going beneath the skull and meninges and penetrating the cortex, the sensory probes can get close enough to measure individual neurons.
