Quoting William Flynn Wallace:
> Perhaps they stimulated the ascending reticular activating system? RAS.
They specifically targeted the central lateral thalamus by using an
array of 24 superfine (12.5 micrometer) electrodes and were guided by
hi resolution imaging technology, so I have to assume that their
anatomical targeting was precise. But according to their introduction,
the CL thalamus is directly connected to the RAS so maybe there was
some current leakage to the RAS? I don't know. The article is free to
download if you want to judge for yourself:
"However, the central lateral thalamus (CL) may have a special
relation to consciousness. CL damage is linked to disorders of
consciousness (Schiff, 2008). Anatomically, CL receives input from the
brainstem reticular activating system. It also projects to superficial
layers and reciprocally connects with deep layers of the
frontoparietal cortex (Kaufman and Rosenquist, 1985, Purpura and
Schiff, 1997, Towns et al., 1990). Thus, CL is well positioned to
influence information flow between cortical layers and areas."
