  • Title: [The effect of otolith entrances upon horizontal nystagmus induced by stimulation of semicircular ducts and retina in pigeons].
    Author: Stolbkov IuK, Orlov IV.
    Journal: Ross Fiziol Zh Im I M Sechenova; 2011 Sep; 97(9):968-79. PubMed ID: 22165208.
    Abstract:
    The semicircular ducts in pigeons were stimulated either in an isolated way (the angular acceleration being 10 degrees/c2) or together with the otolith organs (the peak value of the interaural acceleration being 0.5 g). In one and the same situation, both the inhibitory and the activating otolith effects on nystagmus were found. In one and the same animal, changes of the postoptokinetic and canal nystagmuses could be qualitatively different. The results obtained contradict the hypothesis of changes in the "velocity accumulator" time constants as the only cause of changes in the postoptokinetic and rotatory nystagmuses under conditions of low-frequency otolith stimulation.
