Defense Intelligence Reference Document Technological Approaches To Controlling

Defense Intelligence Agency · 36 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 23 March 2010, was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It surveys invasive and noninvasive brain-machine interface technologies for controlling external devices without limb-operated interfaces. The technologies covered include EEG, MEG, fMRI, NIRS, and implanted electrode arrays. It concludes that noninvasive electrical monitoring is the most promising near-term approach. In the long term, it favors invasive single-neuron cortical connections that use optical stimulation or chip-based arrays.

Figure 13. Experimental Arrangements. (A):
arrangement for simultaneous recordings of neuronal
activity, electromyograms (EMGs), and movements in the
freely behav,ng an,mal. Electrophysiolog,cal recordings
and the video record,ngs were synchronized by pulses (1
Hz) recorded simultaneously by both systems (Synchro).
(B): arrangement for recording vestibular responses in
RS neurons during swimming. Central, denervated region
of the body was fixed in the exper,mental device.
Lamprey could perform locomotor-like undulatory
movements by its anterior and posterior body parts
(ind,cated by arrows). Device could be rotated manually
(a, roll tilt angle).
Additional studies utilizing neurological signals generated from the lamprey have been
equally promising in eliciting cognitive responses that translate a controlled response
into a machine's activity. In a similar experiment, Deliagina, and coworkers (Reference
30) used the activity of reticulospinal neurons recorded from a swimming lamprey to
