The influence of intraoperative auditory brainstem responses on vibroplasty coupling-quality and analysis of the impact of different fixation steps on the coupling.

Purpose: The Vibrant Soundbridge (VSB) is an established active-middle-ear-implant for patients with moderate-to-profound hearing-loss. This surgery is referred to as "Vibroplasty". Sufficient transfer of the VSB's floating-mass-transducers (FMT) energy to the inner ear is a crucial factor influencing the coupling-quality (CQ).

Managing increased demand for mental health services in a public hospital emergency department: a trial of 'Hospital-in-the-Home' for mental health consumers.

Increasing demand from mental health consumers for crisis assessment and intervention in public Emergency Departments (ED) has placed considerable strain on the resources of the ED and long delays awaiting admission are experienced. At Flinders Medical Centre in South Australia, the Psychiatry Department trialled a 'hospital-in-the-home' service to relieve the pressure on the ED and enhance inpatient capacity. The trial has been successful in diverting mental health consumers directly to intensive home-based services from the ED and freeing up beds in the inpatient unit.

Infant temporal contrast sensitivity functions (tCSFs) mature earlier for luminance than for chromatic stimuli: evidence for precocious magnocellular development?

In order to investigate the development of luminance and chromatic temporal contrast sensitivity functions (tCSFs), we obtained chromatic and luminance contrast thresholds from individual 3- and 4-month old infants, and compared them to previously obtained functions in adults. Stimuli were moving sinusoidal gratings of 0.27 cyc/deg, presented at one of five temporal frequencies: 1.

Infants code the direction of chromatic quadrature motion.

The present experiment uses a quadrature motion paradigm to investigate the motion correspondence cues used by young infants for coding the direction of motion of red/green isoluminant gratings. Three-month-old infants and adults were tested with 0.25 c/d luminance-modulated or red/green isoluminant gratings, either moving continuously or shifted in spatial quadrature.

Infant color vision: temporal contrast sensitivity functions for chromatic (red/green) stimuli in 3-month-olds.

In order to investigate the development of temporal contrast sensitivity functions (tCSFs) for chromatic (red/green) stimuli, we obtained chromatic contrast thresholds from 3-month-old infants and adults using behavioral techniques. Stimuli were moving or counterphase-reversing sinusoidal gratings of 0.25 c/deg.
