the aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (pma) and the intelligence quotient (iq) of educable mentally retarded (emr) children. the sample consisted of 24 emr girls (mean age = 11.98+1.43 years and iq = 70.58+ 9.95). then, they were matched and assigned to two groups of intervention and control according to their iq and pma ...

To what extent are motor networks underlying rhythmic behaviors rigidly hard-wired versus fluid and dynamic entities? Do the members of motor networks change from moment-to-moment or from motor program episode-to-episode? These are questions that can only be addressed in systems where it is possible to monitor the spiking activity of networks of neurons during the production of motor programs. ...

the relationship between motor skills and other aspects of personality, such as self-concept, social and emotional behavior, proposes the necessity of working on motor skills and activities. investigation of the social abilities seems beneficial for whom with the special needs. the current study investigated the influence of yoga rhythmic movements on social interactions of children with mental...

While there are many instances of single neurons that can drive rhythmic stimulus-elicited motor programs, such neurons have seldom been found to be necessary for motor program function. In the isolated central nervous system of the marine mollusc Tritonia diomedea, brief stimulation (1 sec) of a peripheral nerve activates an interneuronal central pattern generator that produces the long-lastin...

Abstract The current study presents a rhythmic music program to acquire some motor skills for children with Down syndrome. research sample was taken from one of the specialized syndrome learning centers children, and in random manner. consisted 20 boys girls divided into experimental control groups. researcher also prepared list appropriate these (walking, running, jumping, throwing), addition ...

The neural substrates of motor programs are only well understood for small, dedicated circuits. Here we investigate how a motor program is constructed within a large network. We imaged populations of neurons in the Aplysia pedal ganglion during execution of a locomotion motor program. We found that the program was built from a very small number of dynamical building blocks, including both neura...

We report on the preliminary development of a model of sensory-motor control and rhythmic motor coordination that proposes a solution to the \timing" problem in the theory of motor control and a uniication the \motor program" and the \systems dynamics" points of view. Subsets of oscillating associative memories modeling cortical columns are coupled to form a rhythmic time base of counters that ...

This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related increase in frequency of vocal-motor coordination, g...
