Introduction The medial olivocochlear reflex (MOCR) is part of the binaural processing strategies and influences efferent auditory pathway. Activation by contralateral noises has an inhibiting impact on cochlear amplifier. Otoacustics emissions are established method to visualize reflex, however, this technique yielding some methodical disadvantages. Visualizing MOCR via brainstem response (ABR...

Abstract: To assess the effect of penetration depth of the surface tripolar electrical stimulation, Tripolar TENS was applied with different intensities (equal to sensory threshold (ST), 1.25 ST, 1.5 ST) on vertebral column of twenty healthy and three hemiplegic subjects. The cathode of TENS was laid on the T11 vertebra and anodes were put 3cm apart from cathode, longitudinally and in the anod...

Presentation of a weak stimulus, a prepulse, before a reflex-evoking stimulus decreases the amplitude of the reflex response relative to reflex amplitude evoked without a preceding prepulse. For example, presenting a brief tone before a trigeminal blink-eliciting stimulus significantly reduces reflex blink amplitude. A common explanation of such data are that sensory processing of the prepulse ...

In spinal cord injuries, direct trauma by edges of sublaxated or dislocated vertebrae and indirect ischemia as a result of vascular injury necrotize the neural tissue. After spinal cord injury, tissue loss appears as micro- or macrocavitation. Accumulations of non-neuronal cells substitute spared tissue and halts axon regrowth. Lack of supporting cells (secreting trophic factors and matrix) agg...

To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...
