The primate reticulospinal tract, hand function and functional recovery
The primate reticulospinal tract is usually considered to control proximal and axial muscles, and to be involved mainly in gross movements such as locomotion, reaching and posture. This contrasts with the corticospinal tract, which is thought to be involved in fine control, particularly of independent finger movements. Recent data provide evidence that the reticulospinal tract can exert some in...
متن کاملDirect and indirect connections with upper limb motoneurons from the primate reticulospinal tract.
Although the reticulospinal tract is a major descending motor pathway in mammals, its contribution to upper limb control in primates has received relatively little attention. Reticulospinal connections are widely assumed to be responsible for coordinated gross movements primarily of proximal muscles, whereas the corticospinal tract mediates fine movements, particularly of the hand. In this stud...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولFunctional properties of primate spinal interneurones during voluntary hand movements.
The activity of cervical spinal interneurones (INs) was recorded in monkeys performing alternating hand movements. The contribution of INs to voluntary movement was determined by their response patterns during ramp-and-hold wrist movements and their postspike effects on forelimb muscle activity. Most INs were active during both flexion and extension, in contrast to the unidirectional activity o...
متن کاملHand Function Related to Age and Sex
Objectives: The purpose of this study was for evaluation of relationship between hand function and age, sex by Jebson Taylor Test.This study determined whether age might be a factor when associated with sex. Methods: In this study Jebson Taylor was evaluated on hand in 180 normal males and females (0.50% male, 0.50% female) in each of the following 7 subtest in 3 age groups: (15-25), (35-45)...
