As scientists seek to understand more about the brain and how it functions, neuroimaging modalities such as magnetic resonance imaging (MRI) provide integral tools in this pursuit. However, an MRI is not possible for all …

The sound beneath the waves
If you’ve ever seen a graphical representation of a sound, you are probably familiar with what it looks like: hundreds of steep, tightly packed peaks and valleys, all of different heights, moving above and below a common line of symmetry that cuts horizontally through the middle. “When a sound travels through the air, it basically sets the molecules around us in motion, using sound pressure to create sort of a wave,” says Waisman researcher Michaela Warnecke, PhD.
Binaural Hearing and Speech Lab
Recruiting typically developing children 7-12 years of age who meet the following criteria: Native English speakers, normal hearing, no history of recurring ear infections, and pressure equalization (PE) tubes. To find out more visit the …
Ruth Litovsky, PhD – Slide of the Week
To investigate the feasibility of using functional near infrared spectroscopy (fNIRS) to image cortical activity in cochlear implant (CI) users and normal hearing (NH) adults, using either visual-speech or auditory-speech.
Ruth Litovsky, PhD – Slide of the Week
Many people with single-sided deafness have tinnitus in the deaf ear (and normal hearing in the other ear). We are conducting a clinical trial in collaboration with surgeons at Harvard Medical School, to determine if a CI in the deaf ear provides: (A) relief from tinnitus due to the electrical stimulation, and (B) improved ability to localize sounds.

Title: Does Bilateral Experience Lead to Improved Spatial Unmasking of Speech in Children Who Use Bilateral Cochlear Implants? Legend: We vary the spatial locations of target speech and masking speech, so they are co-located (A) …

Title: Listening effort, also known as cognitive load, is measured with pupil dilation (pupillometry). When speech sounds are degraded, people expend greater amount of ‘cognitive load’ to decipher the meaning of the speech. Legend: A: …
Blue Sky Science: How do we hear?
How do we hear? And how can cochlear implants help those with impaired hearing? Waisman researcher Ruth Litovsky, PhD, answers these questions in the latest episode of Blue Sky Science, a collaboration of the Wisconsin …
Waisman Center investigator Ruth Litovsky, PhD named a Fulbright Scholar
Ruth Litovsky, PhD, a Waisman Center investigator and professor of communication sciences and disorders, is a 2014-15 Fulbright Scholar for the East-Asia Pacific Region. Litovsky is an internationally-recognized expert on auditory perception — how the brain processes sound to enable people to hear and communicate in noisy environments.
