ABSTRACT Detailed knowledge of the topographic organization and precise access to spinal cord segments is crucial for neurosurgical manipulations as well in vivo neurophysiological investigations networks involved sensorimotor visceral functions. Because high individual variability, accurate identification particular portion lumbosacral enlargement normally possible only during postmortem dissection. Yet, it often necessary determine location prior investigation, targeting manipulations,...
Impairments of the lower urinary tract function including urine storage and voiding are widely spread among patients with spinal cord injuries. The management such includes bladder catheterization, surgical pharmacological approaches, which reduce morbidity from tract-related complications. However, to date, there is no effective treatment neurogenic restoration function. In present study, we examined neuromodulation detrusor (Detr) external urethral sphincter by epidural electrical...
Transcutaneous stimulation is a neuromodulation method that efficiently used for recovery after spinal cord injury and other disorders are accompanied by motor sensory deficits. Multiple aspects of transcutaneous optimization still require testing in animal experiments including the use pharmacological agents, lesions, cell recording etc. This need initially motivated us to develop new approach transvertebral (SCS) test its feasibility acute chronic on rats. The aim current work was study...
Abstract We show that epidural spinal cord stimulation can elicit stable bidirectional locomotion of decerebrate cats on a split-belt treadmill. The stepping pattern one limb was similar to unidirectional forward walking and, the other—was backward walking. This confirms and brainstem circuitry are sufficient control such complex extraordinary motor tasks driven by somatosensory input. Interlimb coordination during preserved in 2 out 4 animals ‘extreme’ conditions when treadmill belts...
The optimization of multisystem neurorehabilitation protocols including electrical spinal cord stimulation and multi-directional tasks training require understanding underlying circuits mechanisms distribution the neuronal network over cord. In this study we compared locomotor activity during forward backward stepping in eighteen adult decerebrated cats. Interneuronal networks responsible for were visualized using C-Fos technique. A bi-modal rostrocaudal C-Fos-immunopositive neurons...
Abstract Either effects or aftereffects of visual illusions are well studied at the domain while there few studies motor tasks such as grasping pointing illusory. The Müller-Lyer and Ponzo in sensorimotor were studied. We used four illusions: two versions (upper/bottom shafts appear longer) (classical inverted, upper/bottom longer). They presented to experimental groups, each type one groups. A fifth group was shown neutral stimuli (two horizontal lines, under another). At first, above...
Background: A growing number of studies have reported Coronavirus disease (COVID-19)-related to both respiratory and central nervous system dysfunctions. This study evaluates the neuromodulatory effects spinal cord transcutaneous stimulation (scTS) on functional state in healthy controls patients with post-COVID-19 deficits as a step toward development rehabilitation strategy for these patients.; Methods: In this before-after, interventional, case-controlled clinical study, ten individuals...
The role of conscious control level at the sensorimotor measurements оf different visual illusions (Muller-Lyer, Ponzo, and trapeze) was investigated. We try to vary this by changing hand performing task excluding feedback. It shown that affects performance higher than presence/absence left performs tasks generally more accurate right one. explain our results on base hypothesis about existence hemisphere-specific systems objects representations (metric categorical).
Cat is a prominent model for investigating neural networks of the lumbosacral spinal cord that control locomotor and visceral activity. We previously proposed an integral function, establishing topographical relationship between segments vertebrae in adult animals. Here, we investigated dynamic this through early middle periods development kittens. calculated length each vertebra relative to total region from 13th thoracic (T) 7th lumbar (L) (V) as well segment T13 three-dimensional sacral...
Abstract The characteristics of precise hand movements in Dry Immersion (DI) have been studied. Motor tasks were cyclic single-joint corresponding to the length and orientation presented horizontal or vertical segment carried out for 5 s with without visual feedback. studies participation 35 test healthy volunteers divided into three groups: control ( n = 10), 6-hour DI 11), 5-day 14). In group, was times, lying on couch, imitating cyclogram a DI—once before DI, morning day evening 2 h after...

Locomotion in different directions is vital for animal life and requires fine-adjusted neural activity of spinal networks. To compare the levels recruitability locomotor circuitry responsible forward backward stepping, several electromyographic kinematic characteristics two modes were analysed decerebrated cats. Electrical epidural cord stimulation was used to evoke locomotion on a treadmill belt. The functional state bilateral networks tuned by symmetrical asymmetrical stimulation. A...
<b><i>Introduction:</i></b> The changes in knee axial rotation play an important role traumatic and non-traumatic disorders. It is known that support afferentation can affect the rotator muscles. condition of innervation semitendinosus (ST) biceps femoris posterior (BFp) has changed non-terrestrial terrestrial vertebrates evolution; thus, we hypothesized this situation might be replayed by hindlimb unloading (HU). <b><i>Methods:</i></b> In...
