title: [Protein-sensitive elements of the labellar sensillas of Musca domestica flies].
abstract: Using electrophysiological technique of registration of impulse activity in chemoreceptive cells of the labellar sensillae of the housefly, it has been demonstrated that taste hairs are not uniform in their properties. They differ from each other by the set of receptive elements which exhibit different sensitivity, range of selectivity and pattern of impulse activity. It was shown that albumen solution (10(-5) M) evokes the activity in 1--2 cells of a sensilla which are classified as water and sugar receptors. Among these receptors, protein-sensitive and protein-insensitive cells may be distinguished. Considering the inhomogeneity of sugar receptor sites, it was suggested that chemo receptive membranes in most sensitive to protein cells contain more numerous fructose receptive sites, that glucose ones.
