Tinnitus is a serious neurological condition effecting 10-15% of adults, and can lead to other symptoms such as difficulty concentrating and sleeping, anxiety, and depression. Currently there are no FDA approved drugs to prevent or treat tinnitus, mainly due to a lack of understanding of its cellular and molecular pathways. T- and L- type calcium channels have been implicated in the modulation of tinnitus, as well as the dysfunction of gamma-aminobutyric acid (GABA) neurons. This study used the sound-based avoidance detection (SBAD) method in order to detect tinnitus and determine whether pharmacological treatments had an effect in mediating tinnitus. T-type …
Cortical Stimulation Mapping Of Heschl’S Gyrus In The Auditory Cortex For Tinnitus Treatment, Austin Huang
Cortical Stimulation Mapping Of Heschl’S Gyrus In The Auditory Cortex For Tinnitus Treatment, Austin Huang
CMC Senior Theses
Tinnitus is the perception of sound in the absence of an actual sound stimulus. Recent developments have shifted the focus to the central nervous system and the neural correlate of tinnitus. Broadly, tinnitus involves cortical map rearrangement, pathological neural synchrony, and increased spontaneous firing rates. Various cortical regions, such as Heschl’s gyrus in the auditory cortex, have been found to be associated with different aspects of tinnitus, such as perception and loudness. I propose a cortical stimulation mapping study of Heschl’s gyrus using a depth and subdural electrode montage to conduct electrocorticography. This study would provide high-resolution data on abnormal …
