Brainscans as a Form of Identification
Brainprint scans are considered the definitive method
for identifying egos. Contrary to popular misconceptions,
the term “brainwave scan” is a misnomer,
as this form of identifier is not based on simple
electroencephalography (EEG: a reading of the electrical
activity created by neurons firing within the
brain). The actual process for recording brainprints
for identification purposes goes much deeper than
that. It is based on the electrophysiological responses
(event-related potentials) t...The problem is that they must be updated regularly because the brain is always changing.

What Makes Something a Distinct Object?
Let me look at the envelope from a very basic point of view,
that of the neurophysiology of raw perception itself. Forgive me
if it’s a bit oversimple. Take me-on the back of your retina
I’m upside down, focused at the center but fuzzy at the edges,
two-dimensional, a barrage of photons releasing rhodopsin and
triggering neural impulses along the visual nerve. At the same
time, the pressure wave I’m setting up right now with all this talk
is causing little hairs inside the cochlea, in y...Folksonomies: perception
Folksonomies: perception
Our perceptions are built on photons hitting our retinas and pressure variations tickling the folicles in our cochleas... so how does all that become something distinct in our mind's eye?
