BACKGROUND While the neural and mechanical effects of whole nerve cutaneous stimulation on human locomotion have been previously studied, there is less information about effects evoked by activation of discrete skin regions on the sole of the foot. Electrical stimulation of discrete foot regions evokes position-modulated patterns of cutaneous reflexes in muscles acting at the ankle during stand...

STUDY DESIGN A single-case study design. OBJECTIVES To examine the effect of electrical stimulation of the vastus medialis muscle on stiffness, pain and function for a patient with delayed functional progress following a lateral patellar retinacular release. BACKGROUND Five months after an arthroscopic lateral patellar retinacular release, the patient, although highly motivated, had made li...

We recorded from 118 neurons in the visual sector of the thalamic reticular nucleus (TRN) in anesthetized rabbits. Cells were identified by their location and characteristic burst responses to stimulation of the primary visual cortex (Cx) and optic chiasm (OX) and were classified into two groups. Type I cells had relatively short latencies from both OX and Cx stimulation, and the latency from O...

Secretion of prolactin in nine patients with amyotrophic lateral sclerosis and in seven healthy men was investigated with the use of metoclopramide stimulation and bromocriptine inhibition tests. Blood serum prolactin concentration was determined in the basal state and 30, 60 and 120 minutes after oral administration of 10 mg metoclopramide or 2.5 mg bromocriptine. A period of 3 days intervened...

The central representation of neurogenically mediated coronary vasoconstriction produced by activation of the sympathetic nervous system was examined in anesthetized cats instrumented for continuous recording of coronary and femoral blood flows, arterial pressure, and heart rate. Electrical stimulation in a small region of perifornical lateral hypothalamus increased arterial pressure, heart rat...

Lateral lemniscus, a relay nucleus of auditory sensation, is involved in the control of phonatory movements such as human speech and vocalization of animals. The present study was designed to test whether neurons in the lateral lemniscus contributed to the control of swallowing, one of non-phonic oro-pharyngolaryngeal movements. In acutely decerebrated cats (n=15), swallowing was induced by ele...

OBJECTIVES To examine vestibular control of balance in those who recovered the ability to stand after middle cerebral artery (MCA) stroke. METHODS Sixteen patients with MCA stroke were compared with 10 age matched controls. Two additional patients were studied with isolated corticospinal tract lesions, one each at the level of the pons and medulla. Vestibular evoked postural responses were ob...

The medullary reticular formation (MRF) of the neonatal mouse is organized so that the medial and lateral MRF activate hindlimb and trunk motoneurons (MNs) with differential predominance. The goal of the present study was to investigate whether this activation is polysynaptic and mediated by commissural interneurons with descending axons (dCINs) in the lumbar spinal cord. To this end, we tested...

Pre-sowing laser light stimulation is a method commonly used to increase the productivity of legume species. However, it has not been proved that single-laser more effective technique for enhancing plant and seed yield quality than using different lights in sequence, by which means synergistic relations are produced. A two-year, single-factor field experiment was performed order test selected c...
