Sound localization tes(s and WFS measurements in the median plane were carried OUI under [he conditions of progressively occluding three pinna cavities: scapha, fossa, and conchs, The results show that [he spectral cue in median plane localization is mainly formed by conchs.

Polyotia is an extremely rare type of the auricular malformation that is characterized by a large accessory ear. A 3-year-old girl presented to us with bilateral auricular abnormalities and underwent two-stage corrective operation for polyotia. In this report, we present the surgical details and postoperative outcomes of polyotia correction in the patient. Relevant literature is reviewed.

The two British species of Pandora are adapted for life on muddy-sand. P. inaequivalvis is taken from very sheltered shores at low-water mark and down to 10 fathoms. P. pinna is taken from depths of over 40 fathoms. Both species are markedly inequivalve. This is probably connected with the habit of lying horizontally. The mantle muscles and the ciliary mechanisms of the mantle and gills are des...

The action currents produced by heart muscle and other tissues immersed in or in contact with a large body of conducting material are distributed in accordance with the laws that govern the flow of electric currents in volume conductors. The curve obtained when one electrode (the exploring electrode) is placed very close to and the other (the indifferent electrode) very far from the active tiss...

The literature on occlusive thrombi of the auricles has been reviewed in order to identify the symptom complex attributed to this condition. The clinicopathological findings are presented in four new cases which fit this symptom complex. Two cases are notable in that one is that of a ball thrombus occurring in the absence of mitral stenosis and another the first reported case of pedunculated th...

MANY ELECTROCARDIOGRAPHERS have discussed the differentiation of atrial flutter from atrial tachycardia with block. Some have concluded that there is no difference;' others, including ourselves, hold the opposite view.2 We find the methods described here useful in making the distinction in practice and of interest in their bearing on the theoretical mechanism of atrial flutter. There are three ...

The experiments that have been reported indicate that stimulation of either the right vagus or the left vagus nerve is equally effectual in blocking impulses from the auricles to the ventricles when auricular fibrillation is present. Stimulation of the left vagus nerve is as effectual in blocking impulses from the normally beating auricles as from the auricles when in a state of fibrillation, a...

The Pinna illusion (Pinna & Brelstaff, 2000) consists of two concentric rings of micropatterns that appear to counter-rotate when the observer moves towards the stimulus. There have been several reports that the illusion is stronger when the retinal expansion is produced by observer self-motion than when produced on a computer screen without observer self-motion. In fact, we found that the illu...

Calcitonin gene-related peptide (CGRP) is present in sensory nerve fibers in the heart and around peripheral arteries. On interaction with specific CGRP binding sites and activation of adenylate cyclase, CGRP causes vasodilation and has positive inotropic and chronotropic effects on the heart. In the present study, human CGRP I and II exerted positive inotropic effects on isolated human right a...

After frog auricles have been in contact with a suspension of bacteria or bacteria-free supernatant fluid, newly synthesized bacterial ribonucleic acid (RNA) is recovered in animal cells. It appears that the presence of bacterial deoxyribonucleic acid (DNA)-dependent RNA polymerase is necessary for the transcription of bacterial DNA in the host cells. This phenomenon seems to be related to a tr...
