Background Scoliosis improvement after surgical treatment of Chiari I and syrinx has been reported [1]. Incidence of scoliosis progression after decompression surgery has been reported as high as 48%. The conservative treatment with brace in these patients is not effective and scoliosis is typically progressive [2]. Spontaneous resolution of CT syrinx and Chiari I in paediatric population is un...

We investigated whether activity of expiratory muscles reflects lateralized activity of the vocal organ during production of birdsong. Respiration and syringeal motor activity were assessed in brown thrashers by monitoring bilateral airflow and subsyringeal air sac pressure, together with the electromyographic activity of expiratory abdominal muscles and vocal output. Activity of expiratory mus...

Syrinx is a newly developed PC-based software package designed for interactive playback of animal vocalizations and for digital sound recording and analysis in the lab or in the field. Syrinx permits flexible modeling of complex vocal interactions in an interactive playback setting. Large numbers of sounds can be stored on disk as digital wave files for instant recall in the field. The playback...

Five patients with chronic arachnoiditis and syringomyelia were studied. Three patients had early life meningitis and developed symptoms of syringomyelia eight, 21, and 23 years after the acute infection. One patient had a spinal dural thoracic AVM and developed a thoracic syrinx 11 years after spinal subarachnoid haemorrhage and five years after surgery on the AVM. A fifth patient had tubercul...

In songbirds, the ability to learn and render the species-specific song is influenced by the development of both the song nuclei in the brain and the syrinx (bird's vocal apparatus) early in the bird's life. In black-capped chickadees (Poecille atricapillus), habitat quality is known to affect song structure, with birds in high-quality habitat (mature forest) having a higher song consistency th...

This paper describes the Syrinx Spoken Language Sys tem (Sylan), an automated dialogue system that is fully integrated with the Syrinx Large Voca bulary Speech Recogniser (Sycon) into the Syrinx SpeechMaster platform. This platform combines speech recognit ion, natural language processing, dialogue management, telephony and database integra tion into a robust and flexible Voice User Interface t...

INTRODUCTION Post-traumatic syringomyelia is a progressive degenerative disorder that is a well-recognized sequela of spinal cord injury. There is currently no optimal intervention capable of producing satisfactory long-term clinical results. CASE PRESENTATION In this report, we present a 55-year-old Asian man with recurrent syringomyelia after shunt treatment. The syrinx extended from the th...

Recent studies on several species of oscine songbirds show that they achieve their varied vocal performances through coordinated activity of respiratory, syringeal, and other vocal tract muscles in ways that take maximum advantage of the acoustic flexibility made possible by the presence of two independently controlled sound sources in their bipartite syrinx (vocal organ). During song, special ...

BACKGROUND Syringomyelia is a fluid-filled tubular cavity within the spinal cord. The exact pathophysiology of syringomyelia remains complex and uncertain. MATERIAL We present a case of resolution of cervical syringomyelia after cervical disc operation in a follow-up time of 6 months. CONCLUSION Restoration of cerebrospinal fluid flow dynamics between the syrinx and the subarachnoid space v...
