Experimental Description

These quotations from two of Stephen Lisberger’s publications accurately describe his experimentation on rhesus monkeys. In most instances, when water or another form of liquid is used as a reward for a primate, this follows a period of water deprivation. UCSF, the facility in which Lisberger performs his experimentation is known to deprive primates of water for as much as 22 consecutive hours.

Relationship Between Extraretinal Component of Firing Rate and Eye Speed in Area MST of Macaque Monkeys

Methods

Eye movement and neural recordings were obtained from two adult male rhesus monkeys (Macaca mulatta) that had been trained to fixate and pursue visual targets for fluid reward. Monkeys were implanted with a stainless steel socket for head restraint and a scleral search coil for measuring eye position, using methods described in detail elsewhere (Churchland and Lisberger 2000 ). After initial training, monkeys were implanted with stainless steel or cilux cylinders (Crist Instruments, Hagerstown, MD) to allow access to MST for neural recordings. Surgeries were conducted using sterile technique with the monkeys under isofluorane anesthesia, and analgesics were given under the supervision of veterinarians and veterinary nurses during the recovery after each surgical procedure. For each experimental session, the monkey sat in a primate chair and the implanted socket was used to affix the head to the ceiling of the chair. A tube was positioned at the monkey's mouth for dispensing fluid rewards.

Apparent Motion Produces Multiple Deficits in Visually Guided Smooth Pursuit Eye Movements of Monkeys

Surgical procedures

Experiments were performed on six adult male rhesus monkeys that had been trained to pursue single moving targets. Our basic experimental methods have been presented before (e.g., Lisberger and Westbrook 1985 ). Briefly, monkeys were trained to track visual targets and were rewarded with drops of water or Tang. Eye movements were monitored using scleral search coils that had been implanted with the technique of Judge et al. (1980) , using sterile procedure while the monkey was anesthetized with Isofluorane. Postsurgical analgesia was provided for a minimum of 2 days with Buprenorphine (0.01 mg/kg every 12 h). During experiments, monkeys sat in a primate chair with their heads affixed to the ceiling of the chair using a dental acrylic fixture that had been implanted at the same time as the eye coil. Experiments lasted 2-3 h. Methods had been approved in advance by the Institutional Animal Care and Use Committee at the University of California, San Francisco.
