Language in the context of motor activity: Gross and fine motor differences.
… model which predicts that a child's level of motor development may influence speech produced by both parents and child and subsequently the language acquisition style the child will develop. Subjects were eight boys and eight girls, and their mothers. Mothers were given the Motor Skills Domain …

C. elegans integrates food, stress, and hunger signals to coordinate motor activity
… and mechanical agitation on the animal's locomotory behavior are modulated by food deprivation. To explore how C. elegans modulates its locomotion we focused on determining how C. elegans detects bacteria, and explored the roles of biogenic amines, metabolic, and stress signaling pathways on …

Role of the ventral tegmental area, cannabinoid receptors and GABA neurons in motor activity
… play an important role in the generation of motor behavior. Ablation of GABA neurons following intra-VTA administration of the selective toxin dermorphin-saporin was associated with elevated spontaneous locomotor activity at day 7 that normalized to basal levels by day 14 after treatment. …

The effects of alcohol on four behavioral processes: perception, mediation, communication, and motor activity
The research reported is concerned with the effects of alcohol on a maze-based task which had been designed to incorporate independently each of the four behavioral processes described by Berliner, Angell, and Shearer in 1968. Such a design allows study of the relative effects of alcohol on various …

An evaluation of the impact of an individualized motor activity program for learning disabled elementary school children
… was to evaluate the impact of an individualized motor activity program on the level of motor development, perceptual-motor development, physical fitness, self-concept, and academic achievement of learning disabled elementary school children. The participants for this investigation were learning …

Motor Activity in Haemodialysis Patients and Opportunities for Its Optimisation // Двигателна активност при пациенти на хемодиализа и възможности за оптимизирането ѝ
… thesis aims to prove that kinesitherapy improves motor activity, social rehabilitation, and QoL in patients with ESKD. The selection of the studied individuals was made among CKD patients who underwent treatment in 2023-2024 at the dialysis centre at St. Marina University Hospital – Varna. 81 …

The role of specific voltage-activated and calcium-activated potassium currents in shaping motor neuron firing output during rhythmic motor activity
… are necessary for survival. Though in many cases motor neurons (MNs) themselves do not generate the basic motor rhythm, research suggests that the intrinsic properties of MNs may shape the timing of the final motor output. In particular, potassium (K⁺) currents can affect MN excitability and …

Effects of oral delta-9-tetrahydrocannibinol (THC) administration on motor activity and anxiety-like behavior in adolescent and adult Sprague-Dawley rats of both sexes
… may produce an anxiogenic effect and reduce locomotor activity in rats, but it is unclear if this also occurs following volitional, oral intake of THC. Here, we used adolescent and adult rats of both sexes to determine if oral THC would alter locomotor activity in an open-field arena (OFA) and …

Deep Brain Stimulation to Increase Generalized Arousal in Intact Mice and a Mouse Model of Traumatic Brain Injury
… of generalized arousal are presented here: motor activity and sensory (specifically olfactory) responsiveness. In addition to the question of the effectiveness of CT/DBS to increase generalized arousal, this thesis explores the efficiency of a small set of parameters of stimulation. The data …

Conectividade cerebral como característica para classificar tarefas motoras de mesmo segmento corporal: Interação humano-robô
Motor activity classification based on the Electroencephalogram (EEG) has been widely studied to assist brain-computer interfaces (BCIs). However, same limb motor activity classification still remains a challenge due to EEG close spatial representation on the motor cortex area in such case. Brain …

The behavioral effects of nonnutritive sucking on infants of differential fetal growth
… In particular, the infant's pattern of sucking activity may not only reflect the integrity of the infant's nervous system, it may also alter the temporal organization of the infant's behavioral state and motor activity by increasing behavioral quiescence. The purpose of this study was to compare …

Indagine etnofarmacologica su Casimiroa edulis Llave et Lex
… behavioral tests were performed: spontaneous motor activity, anxyolitic, antidepressant, hypnotic-sedative, anticataleptic, anticonvulsant, antinociceptive and antinflammatory activities. The results revealed that the extract of seeds reduced spontaneous motor activity and rearing; in the …

The Study of an Attempt to Improve Motor Abilities of Kindergarten Children in the Pasco Public Schools
… of the study lead to the conclusion that if motor activity of some kind underlies all behavior, including higher thought processes, then educators must be more vigorous in the approach to the physical education programs of children at an early age.

A study of symptom profile and clinical subtypes of delirium
… cross-sectionally and longitudinally. Motor activity studies were controlled and included both subjective and objective measures, aimed at identifying a new approach to defining this clinical subtype as a more pure motor disturbance. This work confirms delirium as a complex …

Physical Exercise as Treatment for Hyperactivity in Children.
… patterns of excessive non-goal-directed motor activity, short attention span, easy distractibility, impulsivity, and associated learning and behavioral problems (Satterfield, Cantwell, and Satterfield, 1974). The syndrome is observed early in life and is more common among boys. The child …

Inhibitory Control of Muscle Activity in Sleep
… I examined the inhibitory control of REM sleep motor activity using both a pharmacological rat model and a genetic mouse model. I characterized the role for GABA and glycine in mediating the REM-specific suppression of muscle activity as well as their involvement in regulating the phasic muscle …

Mapping the Spatial and Temporal Dynamics of Sensorimotor Integration During the Perception and Performance of Wallowing
<p>Similar to other complex sequences of muscle activity, swallowing relies heavily upon ‘sensorimotor integration.’ It is well known that the premotor cortex and primary sensorimotor cortices provide critical sensorimotor contributions that help control the strength and timing of swallowing muscle …

Pitx3Null Mutant (Striatal Dopamine-Deficient) Mice Have Exaggerated Spiny Projection Neuron Responses to l-DOPA and D1 Agonism and Lack Baseline Striatonigral Spiking
… (l-DOPA) strongly stimulates motor activity in parkinsonian patients and animal models of Parkinson's disease. Severe striatal dopamine (DA) loss characterizes Parkinson's disease and its animal models. Given the canonical rate model of Parkinson's Disease pathophysiology based …

Event detection in EEG signals for brain computer interface using expectation-maximation algorithm
… of the parameters of the rest EEG and EEG during motor actions were compared. Statistical analysis of the results indicates that there are differences between maximum-likelihood values of the wavelet coefficients of the rest EEG and EEG undergoing motor activity. Two models of Gaussian mixture …
