| pubmed-article:6978726 | pubmed:abstractText | The function of the sensory organ in semicircular canals of the frog has been tested, at increasing temperatures from 20 to 34 degrees C, by recording the ampullar (Adc) and nerve (Ndc) potentials together with the afferent discharge of impulses in the VIII nerve fibres. The amplitude of the receptor potential increases by increasing the temperature up to 30 degrees C. Postsynaptic potentials and propragated spikes, by converse, are only slightly modified between 20-28 degrees C and are drastically depressed over 28 degrees C. The results are discussed also in connection with the possible use of the enzimatic pretreatment of the preparations to facilitate the insertion of microelectrodes in labyrinthine cells. | lld:pubmed |
