1. Web-based neuromuscular simulator applied to the teaching of principles of neuroscience
INTRODUCTION: The learning of core concepts in neuroscience can be reinforced by a hands-on approach, either experimental or computer-based. In this work, we present a web-based multi-scale neuromuscular simulator that is being used as a teaching aid in a campus-wide course on the Principles of Neuroscience. METHODS: The simulator has several built-in indivi

2. Democracia fiscal e seus fundamentos à luz do direito &economia / Tax equality: law and economics view
Any society must decide how the common expenses will be shared and this has happened for thousands of years. From elements of the own movement of Law and Economics, this thesis formulates a scientific proposition about this theme. Its the fiscal democracy. Starting from the basic assumption that the Law and the Economics influence each other in a dynamic of

3. Neural changes in the spinal cord rights for different types of physical training / Adaptações neurais na medula espinhal de humanos para diferentes tipos de treinamento físico
Introduction: Neural adaptations with physical training have been widely studied. The spinal cord is a possible locus of adaptation. However, longitudinal studies that evaluate directly the spinal cord pathways have not been found in the literature. Therefore, all reports from the literature justify changes found in measured responses to exercise by hypothes

4. Efeito inibidor da finasterida sobre a enzima 5-alfa-redutase na prostata de gerbilos adultos (Meriones unguiculatus)
Prostatic deve1opment and differentiatíon are induced by androgens acting via mesenchymal-epithelial interactions, and during adult life the gland is maintained functionally active by reciprocal homeostatic stromal-epithelial interactions. Hormonal alterations, usually associated with the physical aspects of aging, leads to disruptions of this homeostatic i

5. Reciprocal continuous inhibition in rigidity of Parkinsonism.
A reciprocal continuous inhibition by flexor on extensor muscles was proved during Parkinsonian rigidity. Extensor motoneurone excitability was tested by Hoffmann's reflex and flexor activity was altered by lidocaine anaesthesia of the peroneal nerve (PN). During PN anaesthetic block, a gradual increase of Hoffmann's reflex was noted. It was statistically si

6. Cortical modulation of transmission in spinal reflex pathways of man.
1. The motor actions in the lower limb of transcranial electrical stimulation of the motor cortex have been studied in sitting human subjects. 2. Cortical stimulation induced a short latency inhibition of H reflexes evoked in soleus motoneurones both at rest and during small voluntary contractions of soleus. 3. Spatial interaction between cortical inhibition

7. Reciprocal inhibition between wrist flexors and extensors in man: a new set of interneurones?
1. Interneurones mediating reciprocal inhibition between wrist flexors and extensors in man are characterized using both Renshaw cells and transarticular group I afferent activation. 2. Renshaw cells were activated by reflex discharges evoked by a tendon tap. The tendon tap was applied to the tendon of the muscles from which the Ia fibres responsible for the

8. The regulation of disynaptic reciprocal Ia inhibition during co-contraction of antagonistic muscles in man.
1. The disynaptic reciprocal inhibition from ankle dorsiflexors to ankle plantarflexors was investigated at rest, during tonic plantar- and dorsiflexion and during co-contraction. In relation to rest, it was found to be decreased during plantarflexion and co-contraction, but unchanged during dorsiflexion. 2. When increasing the strength of plantarflexion the

9. The influence of contralateral primary afferents on Ia inhibitory interneurones in humans.
1. Contralateral influences on short latency reciprocal inhibition between wrist extensor and flexor muscles were investigated in twenty-two healthy volunteers. Reciprocal inhibition, probably mediated through the Ia inhibitory interneurone, was measured by conditioning the flexor carpi radialis (FCR) H reflex by weak stimulation of the ipsilateral radial ne

10. Spinal mechanisms in man contributing to reciprocal inhibition during voluntary dorsiflexion of the foot.
1. The inhibition of the soleus Hoffmann reflex (H reflex) during voluntary dorsiflexion of the foot--henceforth referred to as 'natural' reciprocal inhibition--was found to be initiated 50 ms before the onset of the EMG activity in the tibialis anterior muscle and to increase gradually during a ramp-and-hold dorsiflexion. There was a positive correlation be

11. Reciprocal Ia inhibition between ankle flexors and extensors in man.
1. Reciprocal inhibition between antagonist muscle groups at the ankle has been investigated in sixty healthy subjects. Hoffmann reflexes (H reflexes) in the soleus and tibialis anterior muscles were used to assess changes in reciprocal inhibition evoked by electrical stimulation of antagonist muscle nerves. 2. Inhibition of the soleus H reflex was evoked by

12. Reciprocal inhibition following lesions of the spinal cord in man.
1. Reciprocal inhibition was studied in normal subjects and patients with spinal cord lesions by stimulating the posterior tibial nerve below the threshold of the soleus alpha-motoneurone axons and recording the changes in firing probability of single tibialis anterior motor units activated by voluntary contraction. A short-latency (about 35 ms) period of de
