1. Involvement of the TRPV1 channel in the modulation of spontaneous locomotor activity, physical performance and physical exercise-induced physiological responses
Physical exercise triggers coordinated physiological responses to meet the augmented metabolic demand of contracting muscles. To provide adequate responses, the brain must receive sensory information about the physiological status of peripheral tissues and organs, such as changes in osmolality, temperature and pH. Most of the receptors involved in these affe

2. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have

3. Efeitos de TENS e vibração sobre a geração de força e sobre o controle postural humano / Effects of TENS and vibration on force generation and on human postural control
Esta tese de doutorado está dividida em três capítulos. O primeiro capítulo teve sua fundamentação em resultados da literatura, que mostraram que a aplicação de trens de alta freqüência de estimulação elétrica na perna pode gerar forças maiores do que seria esperado pela estimulação direta de axônios motores, por um mecanismo central gerado

4. CaracterizaÃÃo das vias neuro-humorais no retarde do esvaziamento gÃstrico de lÃquidos advindo da distensÃo mecÃnica atrial direita em ratos acordados. / Characterization of neuro-humoral pathways involved in delayed gastric emptying of liquids due to mechanical right atrial stretch in awake rats.
Right atrium mechanical stretch (AS) increases gastric motility in anesthetized rats. We aimed to study the effect of AS on gastric emptying (GE) in awake rats and the related neuro-humoral pathways ivolved. Male albino rats (N=361, 250-280g) had a silicone balloon inserted in the right atrium. After 24-h, the central venous pressure (CVP), heart rate (HR) a

5. Vestibular function evaluation by subjective visual vertical in patients with Parkinsons disease / Avaliação da função vestibular através da vertical visual subjetiva em pacientes com doença de Parkinson
Introduction: Postural instability is a late manifestation of Parkinsons disease (PD). The impairment of postural responses on PD is probably the most important cause of falls. These postural responses depend on vestibular, somatossensorial and visual inputs, and they are integrated on basal ganglia, brainstem and spinal cord. By use of the subjective visual

6. Electromyographic pattern in lower limbs in response to postural perturbations / Padrão eletromiográfico de membros inferiores em resposta a perturbações posturais
Balance depends on the synergic activation of muscles bilaterally, and there is evidence that this coordination is mediated by spinal circuits, which are under supra-spinal control. The objective of this study is to describe neurophysiologic and biomechanical mechanisms involved in the postural control of healthy subjects submitted to a disturbance provoked

7. Pudendal somatosensory evoked potentials in normal women
OBJECTIVE: Somatosensory evoked potential (SSEP) is an electrophysiological test used to evaluate sensory innervations in peripheral and central neuropathies. Pudendal SSEP has been studied in dysfunctions related to the lower urinary tract and pelvic floor. Although some authors have already described technical details pertaining to the method, the standard

8. Functional studies of the ataxin-3 protein / Estudos funcionais da proteina ataxina-3
Spinocerebellar ataxia type 3 (SCA 3) also known as Machado-Joseph disease (MJD) belongs to a heterogeneous group of neurodegenerative diseases of the central nervous system and is characterized by the degeneration of cerebellum and its afferent and efferent ways. The SCA3/MJD gene was mapped on chromosome 14 and was named MJD1, the causative mutation is an

9. Differentiation of autonomic reflex control begins with cellular mechanisms at the first synapse within the nucleus tractus solitarius
Visceral afferents send information via cranial nerves to the nucleus tractus solitarius (NTS). The NTS is the initial step of information processing that culminates in homeostatic reflex responses. Recent evidence suggests that strong afferent synaptic responses in the NTS are most often modulated by depression and this forms a basic principle of central in

10. Angiotensin and baroreflex control of the circulation
There is a close association between the location of angiotensin (Ang) receptors and many important brain nuclei involved in the regulation of the cardiovascular system. The present review encompasses the physiological role of Ang II in the brainstem, particularly in relation to its influence on baroreflex control of the heart and kidney. Activation of AT1 r

11. Fever induction pathways: evidence from responses to systemic or local cytokine formation
The immune and central nervous systems are functionally connected and interacting. The concept that the immune signaling to the brain which induces fever during infection and inflammation is mediated by circulating cytokines has been traditionally accepted. Administration of bacterial lipopolysaccharide (LPS) induces the appearance of a so-termed "cytokine c

12. The effect of knee joint afferent discharge on transmission in flexion reflex pathways in decerebrate cats.
1. Changes in excitability of reflex arcs mediating flexion withdrawal ad crossed extensor reflexes have been examined in decerebrate cats. 2. The excitability of flexion withdrawal and crossed extensor reflexes was shown to be modulated by knee joint position. Flexion withdrawal reflexes were most easily elicited when the knee was extended and crossed exten
