During ontogeny, vertebrate CNS neurons differentiate from relatively simple stem cells to complex units that express unique morphological and electrophysiological characteristics. We have examined several aspects of this developmental process in an identified CNS neuronal type, the Purkinje neuron (PN) of the cerebellum. Our approach has included the use of a tissue culture preparation and imm...

background: prevalence of electrophysiological abnormalities in patients with lumbosacral radiculopathy was evaluated. methods: a cross-sectional study was performed on 97 consecutive patients with the clinical diagnosis of lumbosacral radiculopathy. complete neurological examinations and standard electrophysiological evaluation was performed on the patients. results: patients under study had t...

The knowledge about electrophysiological properties of retinal ganglion cells (RGCs), as well as modulation of these properties, is important not only for understanding the unique physiological functions of RGCs under normal conditions, but also for exploring the cellular mechanisms of retinal neurodegeneration diseases, such as glaucoma. In this paper, we reviewed the progress in electrophysio...

Although previous studies have described the electrophysiological and ultrastructural characteristics of human cardiac fibers, no attempt has been made as yet to describe quantitatively the relationship between the ultrastructural and cellular electrophysiological derangements occurring with cardiac disease, and their clinical manifestations. In this study, we used standard microelectrode techn...

The success of surgery for supraventricular tachycardia (SVT) is evaluated by a variety of methods in different hospitals. Unfortunately, the predictive values of these methods are not known. We therefore compared the various methods in 261 patients undergoing surgery for SVT at Westmead Hospital since 1981. Surgical outcome was assessed by early tests during the first week after surgery (seria...

The review presents the newly published book “Electrophysiological Recording Techniques” by Humana Press. This is an important collection of articles devoted to an issue that has gained increasing attention in modern neuroscience research electrophysiological recording techniques. The present book is a timely update of methods spanning from single cell recordings to local field potentials, cort...

The abdominal and pelvic viscera are innervated by the vagaL splanchnic and pelvic nerves. It is estimated that these nerves have afferent:efferent fibre ratios of 9:1, 3:1 and 1:1, respectively. Despite this numerical preponderance of sensory fibres, the roles of the visceral input remain rather vague. Visceral sensory mechanisms are investigated by applying different kinds of stimulus to spec...
