13. Current perception threshold and reaction time in the assessment of sensory peripheral nerve fibers through sinusoidal electrical stimulation at different frequencies
INTRODUCTION: The Perception Sensory Threshold (ST) for sinusoidal current stimuli at 5, 250, and 2,000 Hz is commonly used in the assessment of peripheral nerve fibers (C, Aδ, and Aβ, respectively). However, the neuroselectivity of these frequencies is far from consensus. In addition, Reaction Time (RT) measurements suggest that 2,000 Hz stimuli excite A�

14. Mapeamento anatômico e funcional das aferências nociceptivas ao núcleo paratrigeminal dos nervos facial, mediano e ciático. / Sciatic, Median and Orofacial Nociceptives Inputs to the Paratrigeminal Nucleus: a funcional and anatomical investigations.
Investigations show the paratrigeminal nucleus (Pa5) as an input site for sensory information from the facial, median and sciatic nerves fields. This study aimed at determining the facial, median and sciatic nerve projections to the dorsal lateral medulla and compared the topographical distribution of the input sites of these nerves to that of nuclear c-Fos

15. Desenvolvimento de protocolos de neuronavegação para estudos de estimulação magnética transcraniana e suas aplicações em voluntários controle e pacientes com acidente vascular cerebral / Development of protocols for Transcranial Magnetic Stimulation Neuronavigated studies and Its Applications in Control and Patients with Stroke subjects
Objetivos A estimulação magnética transcraniana (TMS, do inglês: Transcranial Magnetic Stimulation) e as imagens funcionais por ressonância magnética (fMRI, do inglês: functinal Magnetic Resonance Imaging) são duas técnicas não invasivas de investigação de atividade do sistema nervoso central. Porém essas duas técnicas utilizam estratégias dif

16. FOOD AND NUTRITIONAL STATUS OF CHILDREN BORN PRE-TERM UNDER A PROGRAM OF STIMULATION SENSOR-MOTOR-ORAL / ALIMENTAÇÃO E ESTADO NUTRICIONAL DE CRIANÇAS NASCIDAS PRÉ-TERMO SUBMETIDAS A UM PROGRAMA DE ESTIMULAÇÃO SENSÓRIOMOTORA-ORAL
The sensory-motor-oral (SMO) stimulation during Intensive Care Neonatal period has been proposed in order to facilitate the transition from gavage to oral feeding and thereby promote weight gain, breastfeeding and minimize the difficulties in the introduction of solid foods during childhood. Objective: To determine whether the SMO stimulation influence the i

17. Truques sensoriais em diferentes tipos de distonia e no espasmo hemifacial
Introduction: The dystonia is a syndrome of sustained involuntary muscle contractions always producing twisting and repetitive movements or abnormal postures. Of all movement disorders associated with basal ganglia dysfunction, dystonia is the least understood in terms of underlying pathophysiology. Recent works revealed that basal ganglia cortico-striatal-t

18. Development and assessment of an upper limb hybrid system for quadriplegics / Desenvolvimento e avaliação de um protótipo de sistema híbrido para membro superior de tetraplégicos
Generally, individuals with motor impairments in the upper limbs have difficulties performing the movement of objects, which is essential for the execution of activities of daily living. Thus, these individuals do not perform these activities or perform them inefficiently. Toward satisfactory manipulation, reach and grasp movements of objects performed with

19. Postural control in elderly submitted to multi-sensory versus strength exercises: a randomized single-blind study / Controle postural em idosos submetidos a treinamento resistido versus exercícios multissensoriais: um estudo aleatorizado e simples-cego
The practice of regular exercise in aging is helpful to bring benefits in all aspects older peoples life, especially on senescence individuals postural control that tend to reduce such capacity. The aim of this study was to verify and to analyze the changes promoted by two types of exercise programs on postural control in healthy elderly. The study design wa

20. Estudo da estimulação elétrica nervosa transcutânea (TENS) nível sensório para efeito de analgesia em pacientes com osteoartrose de joelho / Study of transcutaneous electrical nerve stimulation (TENS) for the sensory effect of analgesia in patients with knee osteoarthritis
INTRODUÇÃO: A osteoartrose de joelho (OAJ) é uma das patologias que mais afetam o aparelho locomotor e interferem de forma considerável nas atividades da vida diária, acometendo os indivíduos em faixa etária variável e em diversos graus e níveis de dor articular. As propostas terapêuticas são bastante diversificadas para a osteoartrose (OA), a ter

21. EFEITOS DA ESTIMULAÇÃO SENSÓRIO-MOTORA ORAL REALIZADA ANTES E DURANTE GAVAGEM SOBRE A SUCÇÃO NÃO-NUTRITIVA E NUTRITIVA DE RECÉM-NASCIDOS PRÉ-TERMO / EFFECTS OF ORAL SENSORY-MOTOR STIMULATION PERFORMED BEFORE AND DURING TUBE NON-NUTRITIVE SUCKING AND NUTRITIVE SUCKING ON NEONATAL PRE-TERM INFANTS
Objetivos: Verificar a eficiência da sucção não-nutritiva e nutritiva de recémnascidos pré-termo que receberam estimulação sensório-motora oral antes e durante a oferta de alimento via sonda orogástrica. Metodologia: A amostra foi composta por 29 sujeitos, pequenos ou adequados para a idade gestacional, nascidos entre 28 e 33 semanas de idade gesta

22. Involvement of GABAergic mechanisms of the dorsal periaqueductal gray and inferior colliculus on unconditioned fear
The fact that the dorsal periaqueductal gray (dPAG) and inferior colliculus (IC), together with superior colliculus, medial hypothalamus and amygdala, constitute the brain aversion system has been well-established. Stepwise increases in the intensity of electrical stimulation of dPAG or IC cause freezing and escape responses, which are followed by a freezing

23. Avaliação da percepção de dor aguda em pacientes com transtorno de pânico
Inducing pain and evaluating pain sensations in ethically viable ways have always been a challenging task for those conducting experimental research in Psychology and behavioral areas. This study has evaluated the nociceptive thresholds and the subjective experience of pain in 29 patients diagnosed with Panic Disorder and 29 healthy controls. The participant

24. O estudo das cenas visuais complexas e sua relaÃÃo com a esquizofrenia
Schizophrenia seems to be one of the most serious and complex mental disruptions of multi-factorial character (still indefinite multiple causes). This motivates several studies in neuroscience field, like the perception, to research and open pathways which can contribute with questions about its ethyology. This study aimed the use of complex visual stimulati
