摘要: PURPOSE To investigate whether habituation occurs in ocular counterrolling (OCR), how stable shifted Listing's plane is, and what effects visual stimulation alertness exert on the OCR plane. METHODS Two monkeys (Macaca fuscata) were engaged this experiment. A dual scleral search coil method was used for recording three-dimensional eye movements. Spontaneous movements recorded 2 hours dark light, while each monkey held different static roll positions (up to +/-34 degrees) with its head fixed. Eye also during monkeys' drowsy periods dark. RESULTS In alert conditions, gains showed some fluctuations but did not change consistently seven of sessions nine light. The light differ from those thickness roll-tilt within range upright position During periods, increased, gain decreased. CONCLUSION Ocular shows no roll-tilts monkey. same condition, maintains precision. Visual input does affect OCR, is necessary keep stability
