[comp.ai.digest] What does the brain do between thoughts?

lambert@COD.NOSC.MIL (David R. Lambert) (10/25/88)

Discussion history (abbreviated; see AIList for detail & sources):
>>> 1) What does the brain do between thoughts?
>>> 2) ... there is no "between thoughts" except for sleep....
>>> 3) [Subjects] reported seeing "randomly" blinking lights blink 
         IN RYTHM to a song. Possible concl:  consciousness 
         oscillates.
>>> 4) Other possible concl:  we unconsciously attach meaning to 
         apparently randon patterns (e.g., notice those lit on the 
         beat and disregard others. ... use of tapping, or rubbing 
         motions to influence pace of communications....  P.S.  I'd 
         like to know what 'oscillating consciousness' is supposed 
         to mean. 

As I recall, there are some nice psycholinguistic "click" 
experiments (I don't know the references--about 1973) which show 
that the perceived location of a click which actually occurs at a 
random time during a spoken sentence migrates to a semantic (or, 
perhaps, syntactic) boundary.  Perhaps the brain is actually 
thinking (processing information) all/most/much of the time.  But we 
PERCEIVE (or experimentally observe) the brain as thinking 
intermittently 1) because we notice only the RESULTS of this 
thinking, and 2) do so only when these results become available at 
natural (irregularly spaced) breakpoints in the processing.
