THE ARIZONA SPEECH-LANGUAGE-HEARING ASSOCIATION

January 2019

The Arizona Speech- Language- Hearing Association (ArSHA), is nearing its 60th year representing and advocating for the state and national needs of Arizona Au-diologists and Speech- Language Pathologists. The nearly 500 licensed audiologists in Arizona are represented at the state level by a volunteer force of CSD profes-sionals, who collaborate regularly with various state level organizations. With the help of a consultant and lobbying firm, ArSHA stays current on state government matters and legislation that may affect the CSD professions and the individuals we serve, initiating action when needed and quickly responding to situations as they arise.

ArSHA offers discounted and free ASHA and AAA CEUs at annual conventions, which feature a popular audiology track with engaging speakers and current topics. Convenient, on- demand webinars are also offered free to members and at a discounted rate for non- members. The next convention audiology track will be held Saturday, April 6, 2019, in Phoenix, AZ.

Upcoming webinars in February and June will address two major issues: 1) the association of hearing loss, aging, and cognition in neurodegenerative disorders and 2) the supervision of audiology students. ArSHA encourages Arizona audiol-ogists to join ArSHA to help grow and strengthen the audiology wing of the or-ganization. M embers can assist with making decisions on future professional de-velopment topics and speakers, organizing social and networking events around the state, joining established committees, such as Government Relations and Ethics, or by joining or establishing audiology specific committees, fully supported and funded by ArSHA.

M any rewarding opportunities await those who are ready to step into leadership roles and who want to better serve audiologists throughout Arizona. You are in-vited to get more information on membership by emailing arsha@arsha.org, vis-iting the website at https: / / www.arsha.org/ , or by following the organization on Facebook and Instagram. For questions or comments about what ArSHA has to offer Arizona audiologists, all are encouraged to email current President, Fe M urray, at president@arsha.org.

UPCOMING CONFERENCES

January 2019

DID YOU KNOW???"Auditory adaptation" is a term that seems to be used less frequently in modern day audiol-ogy, despite its well- established importance in basic and clinical science. Auditory adaptation is defined as the decrement in loudness during ongoing exposure to a continuous acoustic stimulus. In the neural system (specifically the auditory nerve), there is a steady decrease in

neural firing rate until approximately 3 minutes of continuous stimulation have passed; after that point, the nerve activity levels off. When the stimulus is stopped, neural firing rates will rapidly increase, returning to pre- stimulus activity levels.

TRIVIA ANSWERS!

DID YOU KNOW??? By conducting electrical stimulation of a dog's cortex, Fritsch and H itzig in 1870 were perhaps the first to attribute various functions to particular loci in the brain. Prior to this, functional brain localization was undertaken mostly by phrenologists, or pseudosci-entists who measured bumps on the skull to predict mental traits- which led to much misinformation and stigma regarding localizing brain functions.

ALL ABOUT LEARNINGOver the past Fall 2018 semester, Dr. M usiek and several first- year AuD students convened an informal Reading, Review, and Commentary group within the Neuroaudiology Lab. Affectionately dubbed "RRC", this group meets periodically to explore and discuss important publications relating to neuroaudiology. Under Dr. M usiek's supervision, group members work collaboratively to extend their knowledge of neuroanatomy, physiology, and diagnostic audiology outside the regular AuD coursework. The RRC plans to continue meeting in the upcoming semester; keep an eye on the Neuroaudiology Newsletter to read more about these activities.
