Prolegomenon for a hypothesis on music as expression of an evolutionary early homeostatic feedback-mechanism. A biomusicological proposal.

摘要: Musical experience and creativity are regarded to be largely depending on cultural conditions hence higher cognitive functions. True as this may be, there are, however, numerous responses music-the urge make music taken into account-which derive from deeper levels of the human organism, namely arousing alternatively moderating vegetative limbic Although behavioral intensity quality emanating such evolutionary early nervous structures affected by influence, they still seem essentially independent. Similar specific acoustical and/or motor patterned stimuli found among some other vertebrates which like humans equipped with sophisticated mechanisms for hearing, sound production locomotion, well tuned each other. However, it is even today an open question whether these manifestations auditive-phonatory-locomotor abilities just analogues or if share a common background. The current discussion matter has accumulated data apparently support latter view pointing that sexual selection would force, first suggested Charles Darwin (153). Other, more recent in genetics neuroscience, interpreted hints at origin elemental organismic feature, metabolic-homeostatic variable due its strength eventually created platform radiation adaptations concerning species-specific sounds locomotions broad spectrum tasks, them selection. This line reasoning here, under reference biological data, made basis hypothetical model expression homeostatic feedback mechanism. Accordingly, central variable, “heart” “core”, not exclusively but appears globally releasing mechanism basic endocrine, autonomous elementally It motoric nature, combination characters, performed repetitive trains impulses. further assumed target operations mainly proteins regulatory effect cellular synaptic states. principal representatives growth factors, especially NGF originally was stimulator within peripheral sympathetical systems appeared also synergetic modulator neuro-endocrine-immuno-reactions, i.e. three (5, 80). One can speculate functionally active level escaped knocked out forceful “higher” younger factors (49:13). hypothesis — roots part occurring natural acoustical-motoric stimulus, manifested great variety auditory behavior implies humankind developed stimulus category oscillate round instable point equilibrium. Exactly structures, stochastic neither too predictable, affect organism sensory-vegetative (59, 102, 137, 151). They addition perceptionally optimal creating cortical space-temporal neural patterns strong interhemispheric coherence (110, 130). According scenario, did originate need communication aspect emerged processes individual aspiration maintain his bodily mental fitness, thus pre-social level. What beneficial single fight survival, good group survival. Starting evolved symbiosis dance play large social functions, where ritual autonomously aesthetical tasks got focal role increased over time always accompanied emotional events. Behind, ticking deep structure cultural-ethical terms totally value-neutral archaic goes without pause, contributing maintenance functional balance body mind individual, well.
