In his introduction, Pinna (2010) quoted one of Wertheimer’s observations: “I stand at the window and see a house, trees, sky. Theoretically I might say there were 327 brightnesses and nuances of color. Do I have ‘327’? No. I have sky, house, and trees.” This seems quite remarkable, for Max Wertheimer, together with Kurt Koffka and Wolfgang Koehler, was a pioneer of Gestalt Theory: perceptual o...

Monaural spectral contrast mechanism for neural sensitivity to sound direction in the medial geniculate body of the cat. J. Neurophysiol. 78: 2754-2771, 1997. Central auditory neurons vary in sound direction sensitivity. Insensitive cells discharge well to all sound source directions, whereas sensitive cells discharge well to certain directions and poorly to others. High-frequency neurons in th...

A scourge of tropical and subtropical jungles, bloodfeeding terrestrial leeches of Haemadipsidae have long confused systematists and defied sensible biogeographic interpretation. The family Haemadipsidae usually includes problematic taxa that neither fit the typical IndoPacific distribution of the group, nor properly match diagnostic characters used to define the family. Historically, four addi...

The auriculotemporal nerve is a sensory branch extending from the posterior section of the mandibular nerve trunk. Its nerve roots form a short trunk, which gives off a number of branches, innervating: the temporomandibular joint, the temporal region, structures of the external ear: auricle, and external acoustic meatus, and the parotid gland. It also conducts excretory fibres to the buccal...

Objective: Prominent ears are generally considered as primary cartilage deformities, but some authors consider that posterior auricular muscles malposition could play a role in the genesis of this malformation. Study design: Auricle dissections of 30 cadavers and histologic sections of 2 fetuses’ ears. Methods: Posterior area of the auricle has been dissected in 24 cadavers preserved with zinc ...

Goldenhar syndrome is a congenital condition that includes anomalies of the derivatives of the first and second brachial arches, vertebral defects and ocular abnormalities. It is also known as oculo-auriculo-vertebrale syndrome (OAVS), hemifacial microsomia, or first or second brachial arch syndrome. It was first described by Van Duyse in 1882 and better studied by M. Goldenhar in 1952. Its tre...

BACKGROUND The limited cranial skin covering auricular implants is an important yet underrated factor in auricular reconstruction for both reconstruction surgery and tissue engineering strategies. We report exact measurements on skin deficiency in microtia patients and propose an accessible preoperative method for these measurements. METHODS Plaster ear models (n = 11; male:female = 2:1) of l...

MANDIBULO-FACIAL dysostosis is the name given by Franceschetti and Zwahlen (1944) and Franceschetti and Klein (1949) to a complex of symptoms which together comprise a congenital oro-facial syndrome (Wildervanck, 1960). Franceschetti and Klein (1949) reviewed the literature and described the typical characteristics of the syndrome as follows: (1) Antimongoloid palpebral fissures with either a n...

Abstract Objective To observe whether the EarWell infant ear correction system makes any difference in terms of treatment effect, duration, complication rate, and nursing care requirements different types auricle deformities. Methods A total 93 patients with auricular deformity (age: <3 months age) who were diagnosed treated Guangzhou Children Women’s Medical Center from April 2018 to Septem...
