1. The Application of P300-Long-Latency Auditory-Evoked Potential in Parkinson Disease
Abstract Introduction Parkinson disease (PD) is a degenerative and progressive neurological disorder characterized by resting tremor, stiffness, bradykinesia, and postural instability. Despite the motor symptoms, PD patients also consistently show cognitive impairment or executive dysfunction. The auditory event-related potential P300 has been described as

2. Evaluation of the effects of erythropoietin and interleukin-6 in rats submitted to acute spinal cord injury
OBJECTIVE: To evaluate the effects of interleukin-6 (IL-6) and erythropoietin (EPO) in experimental acute spinal cord injury (SCI) in rats. METHODS: Using standardized equipment, namely, a New York University (NYU) Impactor, a SCI was produced in 50 Wistar rats using a 10-g weight drop from a 12.5-mm height. The rats were divided into the following 5 group

4. Intensity-dependent effects of cycling exercise on corticospinal excitability in healthy humans: a pilot study
Abstract Aims the aim of this study was to verify the effects of different intensities of locomotor exercise on corticospinal excitability. Methods 18 healthy subjects (27.6 ± 6.5 years,) participated in a design study of three different exercise protocols on a cycle ergometer: (i) 10 min at 75% Wmax (high intensity); (ii) 15min at 60% Wmax (moderate inte

5. Effects of ganglioside G(M1) and erythropoietin on spinal cord lesions in rats: functional and histological evaluations
OBJECTIVE: To evaluate the functional and histological effects of ganglioside G(M1) and erythropoietin after experimental spinal cord contusion injury. METHODS: Fifty male Wistar rats underwent experimental spinal cord lesioning using an NYU-Impactor device and were randomly divided into the following groups, which received treatment intraperitoneally. The

6. Effects of estrogen on functional and neurological recovery after spinal cord injury: An experimental study with rats
OBJECTIVES:To evaluate the functional and histological effects of estrogen as a neuroprotective agent after a standard experimentally induced spinal cord lesion.METHODS:In this experimental study, 20 male Wistar rats were divided into two groups: one group with rats undergoing spinal cord injury (SCI) at T10 and receiving estrogen therapy with 17-beta estrad

7. Neuroprotective effect of epidural hypothermia after spinal cord lesion in rats
OBJECTIVES : To evaluate the neuroprotective effect of epidural hypothermia in rats subjected to experimental spinal cord lesion. METHODS: Wistar rats (n = 30) weighing 320-360 g were randomized to two groups (hypothermia and control) of 15 rats per group. A spinal cord lesion was induced by the standardized drop of a 10-g weight from a height of 2.5

8. Critérios eletrofisiológicos de prognóstico da função facial baseados no pontencial evocado motor do nervo facial intraoperatório durante os diversos tempos cirúrgicos da cirurgia do schwannoma vestibular / Electrophysiological parameters of facial motor evoked potential predict postoperative facial function during vestibular schwannoma resection
O potencial evocado motor facial (PEMF) tem-se mostrado um excelente método de monitorização do nervo facial, gerando resultados bastante confiáveis e reprodutíveis no que tange à predição da função facial pós-operatória. O critério eletrofisiológico mais utilizado até então para tanto tem sido a relação de amplitude do PEMF final-valor de

9. The motor evoked potential in aids and HAM/TSP State of the evidence
OBJECTIVE: We aimed to better understand the involvement of the corticospinal tract, assessed by non-invasive transcranial stimulation, in order to determine the actual involvement of the motor system in patients with HAM/TSP and AIDS. METHOD: An exhaustive MEDLINE search for the period of 1985 to 2008 for all articles cross-referenced for "HTLV-I, HTLV-II,

10. Topographic distribution of the tibial somatosensory evoked potential using coherence
The objective of the present study was to determine the adequate cortical regions based on the signal-to-noise ratio (SNR) for somatosensory evoked potential (SEP) recording. This investigation was carried out using magnitude-squared coherence (MSC), a frequency domain objective response detection technique. Electroencephalographic signals were collected (In

11. Effects of malnutrition and sensory-motor stimulation on auditory evoked potentials
There is evidence that the auditory evoked potential (AEP) is altered by malnutrition both in laboratory animals and in humans. The objective of the present study was to determine whether changes in the AEP caused by malnutrition could be reversed by nutritional rehabilitation and sensorymotor and environmental stimulation during hospitalization. Six childre

12. Avaliação da atividade antinociceptiva espinal da toxina Ph1 isolada dp veneno da Phoneutria nigriventer em rodedores
Calcium influx through voltage sensitive calcium channels (VSCCs) plays an important role on the nociceptive transmission in the dorsal horn of the spinal cord. The intrathecal administration of VSCCs blockers, such as -conotoxin-MVIIA (- CTx-MVIIA) has analgesic effect, but it narrows the therapeutic window, presenting many adverse effects. The Brazilian sp
