Current Opinion in Neurobiology, 1997
The activity of brain serotonergic neurons in both the pontine-mesencephalic and medullary groups is positively correlated with the level of behavioral arousal and/or the behavioral state. This, in turn, appears to be related to the level of tonic motor activity, especially as manifested in antigravity muscles and other muscle groups associated with ...

Handwriting as a motor activity
Insight, 1984Computer-based handwriting exercises were developed for students with handwriting difficulties, but normal vision, in 1976. These exercises were subsequently adapted for blind students by using the computer to translate visual information concerning pen movements and letter shapes into tactile and auditory form.

Surgical Clinics of North America, 1993
The colon exhibits three types of contractions: individual phasic (short and long duration), organized groups (MMCs and nonmigrating motor complexes), and ultrapropulsive (giant migrating contractions). The individual phasic contractions and the MMCs and nonmigrating motor complexes produce extensive mixing and kneading of fecal material and slow net ...

Motor Activity and Verbal Behavior
Perceptual and Motor Skills, 1963The present study was undertaken to investigate the effects of motor activity upon verbal behavior. 120 8th grade students served as Ss distributed among 6 experimental samples. Although Ss failed to condition verbally, and no interaction effect was found between verbal conditioning and motor activity, it was found that Ss engaged in a motor activity (

Development of motor activity in kittens
Developmental Psychobiology, 1980AbstractDevelopmental alterations in motor activity were quantified for the 1st 7 postnatal months in the kitten. Motor activity measured with a stabilimeter was low and constant for the 1st 9 postnatal days, increased markedly until Day 14, and remained stable until Day 21. Locomotor activity measured in an open field decreased slightly during the 1st

Motor and electric activity of the duodenum
American Journal of Physiology-Legacy Content, 1961Recordings of pressure and electric potentials from Biebl loops of the duodenum of trained dogs were used to quantitate and to determine relationships among basic electric rhythm (BER), irregular bursts of spike potentials, and motor action of the duodenum. After control periods, morphine was used to stimulate rhythmic motor activity. The omnipresence

Active motor babbling for sensorimotor learning
2008 IEEE International Conference on Robotics and Biomimetics, 2009For a complex autonomous robotic system such as a humanoid robot, motor-babbling-based sensorimotor learning is considered an effective method to develop an internal model of the self-body and the environment autonomously. In this paper, we propose a method of sensorimotor learning and evaluate it performance in active learning.

Motor activity in depressed children
Journal of Affective Disorders, 2011Motor retardation is a cardinal feature in adult depression. Limited information exists about motor activity in depressed children. The present study evaluated motor activity in depressed children compared to controls and investigated whether motor activity can be linked with the severity of symptoms in depressed children.Motor activity during both day-

Motor Activity, Anticipated Motor Activity, and Young Children's Associative Learning
Child Development, 1976The purpose of this study was to determine whether motor activity, previously assumed necessary to induce imagery in young children's associative learning, actually has to be executed. The results of our experiment with kindergartners clearly suggest not: In conditions where subjects simply planned to the potential motor activity (without executing it),

Cooperativity in the motor activities of the ATP-fueled molecular motors
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2005Kinesin, myosin and F1-ATPase are multi-domain molecular motors with multiple catalytic subunits. The motor mechanochemics are achieved via the conversion of ATP hydrolysis energy into forces and motions. We find that the catalysis of these molecular motors do not follow the simple Michaelis-Menten mechanism.
