Bilateral secondary neurolymphomatosis of the internal auditory canal nerves: A case report

BACKGROUND Neurolymphomatosis describes the malignant lymphomatous infiltration of nerves. METHODS We encountered a unique case of a 47-year-old patient with non-Hodgkins lymphoma presenting with bilateral sensorineural hearing loss, vestibular dysfunction and bilateral facial nerve palsy. RESULTS Magnetic resonance imaging demonstrated enhancement and thickening of internal auditory canal nerves bilaterally consistent with neurolymphomatosis. Patient was treated with combined intrathecal chemotherapy and total brain irradiation. CONCLUSIONS One must always remain vigilant for metastatic disease in patients with sensorineural hearing loss and/or vestibular dysfunction and facial nerve palsy in the context of known malignancy.

variPiano™: A parametric design variable piano visualizing a differential tuning mobile interface

This paper introduces the framework of mobile Computer Music interfaces within the context of Human Computer Interaction (HCI). It examines the unique problems posed by the use of computers by composers and performers of music. It emphasizes on the new various interfacing protocols, metaphors and paradigms that apply HCI design methodologies on the world of music, producing special modules like: performance instruments, digital audio processing tools, haptic - adaptable interfaces. A presentation of the basic concepts involved in the Computer Music world prevails the discussion on the evaluation criteria for Computer Music interfaces. New criteria are introduced, like knowledge representation of musical data and alternate musical interfaces materialization. A survey of various systems, based on the previously mentioned criteria is committed.

Dialectic & reconstructive musicality: Stressing the brain-computer interface

This paper focuses on the framework of non-deterministic mobile Computer Music Interfaces within the context of Human Computer Interaction. A very special subgroup of these interfaces, emerging from the subconscious, comprises the Brain Computer Interfaces that affirmatively expose direct manipulation techniques. Short and long memory experiments with musical exploitation can prove shortcomings in inner-knowledge handling and provide understanding of how the language mechanism provides steady, un-biased speech.

Neurophysiology-Based Acoustic Measurements of Singing Contours

This research focuses on how singing is perceived when amplifying mechanisms vastly enhance its energy contours. This is especially true in big auditoriums, churches or outdoor performances. In practice, the singing voice is altered in its phonetic characteristics. The same time, the listener’s perceptional sensory mechanisms are affected, and in terms of neurophysiological processes, an altered acoustic form is received. Apart from these findings, a new unit for evaluating the equivalent to pure acoustic singing is proposed, when using instrumentation to amplify phonation.

Cochlear implants and wireless connectivity Inner-core Connectivity cradling into the 2.4 GHz Arena

From the advent of simple hearing aids to modern cochlear implants the attempt to restore the human sense of hearing has shown significant progress. Modern cochlear implants and their coupled speech processors enable recipients with hearing loss regain the ability to listen to the world around them. An interesting new feature that is available in new newest speech processors offered by the leading companies in cochlear implants is connectivity through the 2.4 GHz band commonly used in Wi-Fi routers and Bluetooth devices and other wireless connectivity applications. In this paper we provide an overview of cochlear implants as well as the new functions that are available through the use of wireless connectivity.

Chromatic Reconstruction and Musical Aberration: a survey into the Brain Synapses of Musicality

A long issue in music representation is the transforming mechanism between music and colors. As music promotes itself as the basis on which audiovisual arts are fostered, a practical method for correlating music performance with its visual surroundings is needed. This paper describes how our brain detects and allures music in a two dimensional visual space, and how the color superimposition may reversely lead to music production.
