The translation relies on a decoder, an algorithm that infers the movement intentions of the user
from the patterns of their neural activity.
For instance, suppose that experiment after experiment showed that brain wave patterns deviate most
from patterns of neural activity when people are making what look like free choices.

A team
of researchers
from the Department
of Evolutionary Neuroethology, led by Sonja Bisch - Knaden, has investigated whether
neural activity patterns linked to either feeding or egg - laying behavior can already be observed in the antennal lobe, which is the first processing level
of scents in the insect brain.
«It makes sense that the brain would mimic the feeling
of reward it gets
from an enjoyable experience by producing the corresponding
pattern of neural activity.
In this study they measured phase response curves
from a computer simulation
of brain
activity, predicted what stimulus
patterns would suppress the
neural oscillations, and then demonstrated that the stimulation
patterns predicted to suppress the oscillations were in fact effective.
This shift
of perspective invites a change
of approach: instead
of charting average firing rates
of single neurons, we must infer behaviorally relevant
neural codes
from evolving
activity patterns across
neural populations.
Interestingly, these
neural -
activity patterns appeared somewhat distinct
from those that usually appear when brain - scan subjects complete tasks associated with emotions like empathy or thinking about other peopleâ $ ™ s points
of view, which is consistent with the idea that gratitude is a unique emotion.
