THE MOTOR ACTIVITY OF THE VENAE CAVAE [PDF]
JAMA: The Journal of the American Medical Association, 1922 The question as to whether the establishment of a definite peripheral resistance requires active variations in the size of the venous blood-bed has been discussed repeatedly. In general, it may be stated that the resistance encountered by the arterial blood in its passage through the vascular system depends on: ( a ) the size of the arteriocapillary ...

Time estimation during motor activity. [PDF]
Front Hum Neurosci, 2023 Several studies on time estimation showed that the estimation of temporal intervals is related to the amount of attention devoted to time. This is explained by the scalar timing theory, which assumes that attention alters the number of pulses transferred by our internal clock to an accumulator that keeps track of the elapsed time.

Role of astrocytes in rhythmic motor activity. [PDF]
Physiol Rep, 2021 Rhythmic motor activities such as breathing, locomotion, tremor, or mastication are organized by groups of interconnected neurons. Most synapses in the central nervous system are in close apposition with processes belonging to astrocytes. Neurotransmitters released from neurons bind to receptors expressed by astrocytes, activating a signaling pathway ...

The origin of word-related motor activity. [PDF]
Cerebral Cortex, 2015 Conceptual processing of verbs consistently recruits the left posterior middle temporal gyrus (lpMTG). The left precentral motor cortex also responds to verbs, with higher activity for action than nonaction verbs.

THE ORIGIN OF SEGMENTATION MOTOR ACTIVITY IN THE INTESTINE [PDF]
Nature Communications, 2014 The segmentation motor activity of the gut that facilitates absorption of nutrients was first described in the late 19th century, but the fundamental mechanisms underlying it remain poorly understood. The dominant theory suggests alternate excitation and

Are anthropometric characteristics powerful markers to predict the Cooper Run Test? Actual Caucasian data [PDF]
PeerJ, 2023 Background Cardiorespiratory fitness (CRF) is a powerful marker of cardiovascular health, especially in youth. Several field tests can provide accurate measurement of CRF, the Cooper Run Test (CRT) is generally preferred by physical education (PE ...

International fitness scale (IFIS): association with motor performance in children with obesity [PDF]
PeerJ, 2023 Background Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health; and compared with their normal-weight peers, these individuals tend to have a lower level of self-confidence, and consequently lower ...
