Does "No-Go" mean "(subconscious) stop"?

Context:
To further our understanding of the function of conscious experience we
need to know which cognitive processes require awareness and which
do not. Here, we show that an unconscious stimulus can trigger
inhibitory control processes, commonly ascribed to conscious control
mechanisms. We combined the metacontrast masking paradigm and
the Go/No-Go paradigm to study whether unconscious No-Go signals
can actively trigger high-level inhibitory control processes, strongly
associated with the prefrontal cortex (PFC). Behaviorally, unconscious
No-Go signals sometimes triggered response inhibition to the level of
complete response termination and yielded a slow down in the speed
of responses that were not inhibited. Electroencephalographic
