A current study of the world's known sites of this phenomenon has given rise to two hypotheses. In contrast to earlier concepts describing the finger lines as traces of activities restricted to remote parts of caves, they are interpreted as the vestige of a once common mode of hominid behaviour. This postulate is based on precisely the restriction of the petroglyphs to Montmilch, the only soft material whose surface could survive for many millennia. Furthermore, the striking parallels between these psychograms and electrically induced phosphenes are demonstrated. Psychograms are thus interpreted as externalised projections of subjective light images in the cerebral visual centre. This definition will demand a re-assessment of our concepts concerning the evolution of hominid intellectual facilities. ER -
