Exploring How Live Theaters Promote Participation for Children with Special Needs.

Aim: Increasing usage of cultural arts venues by children with special needs has created a need to optimize participation planning. A team of three occupational therapy graduate students and one faculty researcher was invited to provide a local children's theater staff with training for supporting children with special needs. The team aimed to determine how their collaboration with the theater could contribute to understandings of best practices in community participation planning.

Acoustic experience alters the aged auditory system.

Objectives: Presbyacusis, one of the most common ailments of the elderly, is often treated with hearing aids, which serve to reintroduce some or all of those sounds lost to peripheral hearing loss. However, little is known about the underlying changes to the ear and brain as a result of such experience with sound late in life. The present study attempts to model this process by rearing aged CBA mice in an augmented acoustic environment (AAE).

Processing of broadband stimuli across A1 layers in young and aged rats.

Presbycusis can be considered a slow age-related peripheral and central deterioration of auditory function which manifests itself as deficits in speech comprehension, especially in noisy environments. The present study examined neural correlates of a simple broadband noise stimulus in primary auditory cortex (A1) of young and aged Fischer-Brown Norway (FBN) rats. Age-related changes in unit responses to broadband noise bursts and spontaneous activity were simultaneously recorded across A1 layers using a single shank, 16-channel electrode.

Gap detection deficits in rats with tinnitus: a potential novel screening tool.

The study describes a novel method for tinnitus screening in rats by use of gap detection reflex procedures. The authors hypothesized that if a background acoustic signal was qualitatively similar to the rat's tinnitus, poorer detection of a silent gap in the background would be expected. Rats with prior evidence of tinnitus at 10 kHz (n = 14) exhibited significantly worse gap detection than controls (n = 13) when the gap was embedded in a background similar to their tinnitus.

Hearing in laboratory animals: strain differences and nonauditory effects of noise.

Hearing in laboratory animals is a topic that traditionally has been the domain of the auditory researcher. However, hearing loss and exposure to various environmental sounds can lead to changes in multiple organ systems, making what laboratory animals hear of consequence for researchers beyond those solely interested in hearing. For example, several inbred mouse strains commonly used in biomedical research (e.
