Intraocular injection of muscimol induces illusory motion reversal in goldfish.
Induced activation of the gamma-aminobutyric acid(A) (GABA(A)) receptor in the retina of goldfish caused the fish to rotate in the opposite direction to that of the spinning pattern during an optomotor response (OMR) measurement. Muscimol, a GABA(A) receptor agonist, modified OMR in a concentration-dependent manner. The GABA(B) receptor agonist baclofen and GABA(C) receptor agonist CACA did not...

متن کاملIllusory motion of the motion aftereffect induces postural sway.
significant role that visual stimulation plays in postural control has been well established. For instance, visual stimuli simulating self-motion through the environment generate potent postural adjustments in observers In all the studies just cited, the pos-tural adjustments occurred as a result of motion information in a visual stimulus that was presented to the observer (i.e., direct visual ...
متن کاملEvidence against the temporal subsampling account of illusory motion reversal.
An illusion of reversed motion may occur sporadically while viewing continuous smooth motion. This has been suggested as evidence of discrete temporal sampling by the visual system in analogy to the sampling that generates the wagon-wheel effect on film (D. Purves, J. A. Paydarfar, & T. J. Andrews, 1996; R. VanRullen, L. Reddy, & C. Koch, 2005). In an alternative theory, the illusion is not the...
متن کاملIllusory Motion
This study reports a new motion illusion in which saccadic eye movements can produce a perceived jump of a static stimulus presented dichoptically. In three experiments, observers made saccades while viewing a stationary stimulus consisting of a disk and random dots presented separately to the two eyes. In Experiments 1 and 2, by measuring the strength of the perceived motion and the velocity o...
