Monkey Abusers of the Week 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. J Neurophysiol 94: 2416-2426, 2005. First published

Center for Integrative Neuroscience, University of California, San
Francisco, California 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. The Journal of Neurophysiology Vol. 84 No. 1 July

Deficits in Visually Guided Smooth Pursuit Eye Movements of Monkeys Howard Hughes Medical Institute, Department of
Physiology, W. M. Keck Foundation Center for Integrative Neuroscience,
and Neuroscience Graduate Program, University of California, San
Francisco, California 94143 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.
