Our research and technology is licensed from McMaster University in Hamilton, Ontario, Canada. Dr. Larry E. Roberts and Dr. Daniel J. Bosnyak are researchers at the Human Neural Plasticity Laboratory at the Department of Neuroscience of McMaster University and among the leaders in the research of the neural mechanisms that cause tinnitus. You can read about the results of some their groundbreaking research into tinnitus here.
Tinnitus is an auditory phantom sensation (ringing of the ears) experienced when no external sound is present. Most but not all cases are associated with hearing loss induced by noise exposure or aging. Neuroscience research...
The auditory cortex is necessary for the perception of sounds that require integration of neural events for short periods of time and for temporal pattern discrimination. Bilateral ablation of the auditory cortex still allows...
We used the 40-Hz auditory steady-state response (SSR) to compare for the first time tonotopic frequency representations in the region of primary auditory cortex (PAC) between subjects with chronic tinnitus and hearing impairment...
Exposure to sound of sufficient duration and level causes permanent damage to the peripheral auditory system, which results in the reorganization of the cortical tonotopic map. The changes are such that neurons with pre-exposure tuning...
Lateral-inhibitory-networks (LINs) of neurons enhance edges and peaks in their input excitation pattern. In the case of reduced spontaneous input to a region of a LIN, the edges between the normal and abnormal spontaneous input will be enhanced...
Several functional brain attributes reflecting neocortical activity have been found to be enhanced in musicians compared to non-musicians. Included are the N1m evoked magnetic field, P2 and righthemispheric N1c auditory...
Hearing loss due to peripheral damage is associated with cochlear hair cell damage or loss and some retrograde degeneration of auditory nerve fibers. Surviving auditory nerve fibers in the impaired region exhibit elevated and...
