“…The prolonged reaction times in the POST condition may be explained by a lack of motivation during the last of the four conditions. There were no signs in the EEG recordings that a reduced vigilance (Bente, 1984) was the reason for the longer reaction times in the POST as compared to the PRE condition.…”

15 normal volunteers were treated over three weeks with haloperidol (HAL) and in the third week additionally with biperidene (BIP). The order of the EEG spectra at different topographical locations and in different frequency bands during a movement task was analyzed using uncertainty analysis (UA), a multivariate analysis technique based on information-theoretical methods. Different patterns of drug-induced changes were found. HAL decreases the theta and alpha band order at the fronto-central lateral areas but increases it at the fronto-central midline in the theta band and at the parietal areas in the alpha band. With the exception of the fronto-central midline locations, BIP more or less counterbalances the effect of HAL. Volunteers felt unwell and had motor disturbances during HAL and felt well again during HAL + BIP. Reaction time values were increased during HAL and normalized during HAL + BIP.

“…Gewisse Formulierungen und logische, bislang nicht ausgeräumte Inkonsistenzen, die jedoch den Kern der Sache nicht berühren, sind vermutlich die Ursache dafür, daß das Bentesche Vigilanzkonzept sich immer noch gewissen Rezeptionsschwierigkeiten und -aufeine Reihe von Mißverständnissen gegründeten -Vorbehalten gegenübersieht. So hat Bente (1977Bente ( , 1982Bente ( , 1984 an verschiedenen Stellen nicht immer völlig deckungsgleiche Definitionen von "Vigilanz" gegeben. In einer früheren Begriffserläuterung (Bente, 1964 b) wird "Vigilanz" als "psychophysisch neutral" bezeichnet.…”

“…Im Widerspruch zu seiner Konzeption einer ..psychophysisch neutralen Größe" sieht Bente "Vigilanz" an anderen Stellen als physische Größe. So bezeichnet er sie etwa als eine "neurodynamische Größe" (Bente, 1977) oder er spricht von" Vigilanz" als dem "Systemzustand der neuronalen Massenaktivität kortikaler Substrate" (Bente, 1984). Schließlich bedeutet es einen Widerspruch, "Vigilanz" gleichzeitig als theoretisches Konstrukt und als "neurodynamische Größe" (Bente, 1977) zu definieren.…”

The variety of meanings nowadays attached to the notion of "vigilance" essentially mask H. Head's original intentions when he introduced the term more than half a century ago. In an attempt to overcome the obviously existing disturbance in scientific communication, we contrast the new meanings, both with each other and with Head's original conception. We also discuss the importance of "vigilance" as a precursor of a current change of paradigms. We conclude that the original intention of "vigilance" is in line with recently elaborated proposals stressing the self-referential character of living systems. This revised notion of "vigilance" might serve as a conceptual base for empirical research taking self-reference into consideration, and hence for biological research in the true sense of the word.
