Performance sensory-motor

There is, however, a difficulty in interpreting the outcome of these tests of free operant performance, in that it is extremely difficult to distinguish whether the recorded impairments involve an underlying deficit in the motor, sensory or motivational function (Hamilton et al., 1985 Cousins and Salamone, 1996b). Attention has therefore turned to tests in which animals are trained to make rapid movements in response to an imperative stimulus in discrete trial tasks, in which specific changes in signal detection, choice accuracy, reaction time and movement latency can potentially distinguish sensory, motor and motivational components of the deficit.

Rats injected with doses of 20-60 mg/kg of ibogaine displayed slower response times on sensory and sensory-motor tests and were also impaired in performing specific motor reflexes at doses of 40-60 mg/kg. Furthermore, these rats exhibited a marked reduction in locomotor activity as well as in emotionality at doses ranging from 10-40 mg/kg. At higher doses (> 40 mg/kg), rats appeared virtually inactive (78). In other studies, at doses above 25 mg/kg, ibogaine produced ataxia, splayed hind limbs, outstretched forelimbs, Straub tail, and hyperexcitability (79).

Then, Dana Ballard from the University of Rochester discussed the visual representations that affect sensory-motor task performance [ 20]. Volunteers were shown videos of a simulated driving environment and their eye movements, monitored. By tracking saccadic eye movements inferences can be drawn describing the underlying cortical processing [21].

Measurement of Sensory-Motor Control Performance 77-4 Techniques An Overview Tracking Tasks An Overview ... 

This chapter addresses the control function. First, it introduces several important concepts relating to sensory-motor control, accuracy of movement, and performance resources/capacities. Second, it provides an overview of apparatuses and methods for the measurement and analysis of complex sensory-motor performance. The overview focuses on measurement of sensory-motor control performance capacities of the upper-limbs and by means of tracking tasks. 

Tracking tasks are the primary methodological approach outlined in this chapter for measurement of sensory-motor control performance. There are, however, a large number of other approaches, each with their own set of apparatuses and methods, which can provide similar or different data on control performance. It is possible to give only a cursory mention of these other techniques in this chapter (see also Further Information).

Batteries of neurologic sensory-motor tests — These tests can be used to, at least ideally, isolate and quantify the various sensory motor, cognitive, and integrative functions and subsystems involved in sensory-motor control performance as measured globally by, for example, tracking tasks. 

Potvin and associates [Potvin andTourtellotte, 1975 Potvinetal., 1985],nowledbyKondraskeetal. [1984, 1988], have developed what is by far the most comprehensive battery of tests available for quantitative evaluation of neurologic function covering a number of sensory, motor, cognitive, and sensory-motor functions or performance resources. Similarly, Jones et al. [1989, 1993] have developed a battery of compoMent function tests, most of which have been specifically designed to isolate and quantify the various performance resources involved in their tracking tasks. There is, therefore, a close resemblance between the component and tracking tests so as to maximize the validity of comparisons made between them.
