Consciousness absent and present: a neurophysiological exploration.
Backward masking was used to investigate the amount of neuronal activity that occurs in the macaque inferior temporal visual cortex when faces can just be identified. It is shown that the effect of the pattern mask is to interrupt neuronal activity in the inferior temporal visual cortex. This reduces the number of action potentials that occur to a given stimulus, and decreases even more the inf...
متن کاملReactivity to home observation: a comparison of audio recorded behavior with observers present or absent.
THE STUDY COMPARED THE BEHAVIOR OF FAMILY MEMBERS AT HOME AS RECORDED BY AUDIOTAPE RECORDINGS IN TWO CONDITIONS: with an observer present or absent. Behavioral differences were expected as a function of differential reactivity to these observational procedures, but none was found, and there was no evidence of adaptation effects in either condition. In general, significant positive correlations ...

The present paper presents some of these numerous ndings, but mostly foc...
متن کاملPlasma environment at Titan’s orbit with Titan present and absent
[1] To understand the possible large scale influence of Titan on its plasma environment, we study the magnetic fields and plasma measurements, both when Cassini flies close to Titan and when Cassini crosses the moon’s orbit far from it. Using 98 Cassini passes from 06/2004 to 12/2008, we examine the plasma environments at the orbit of Titan with the moon present and absent. In particular, the p...
