In the auditory cortex, do neighbouring neurons receive similar input frow lower levels of processing? In the auditory cortex, neighbouring neurons tend to like sounds that are similar in frequency. We ask whether this is because neighbouring neurons receive similar input from lower levels of the brain (specifically the thalamus). If we zoom out andContinue reading “Vasquez-Lopez et al.

Can ferrets wear earphones? Earphones make it possible to precisely control the sound heard by each ear. This allows us to simulate different forms of hearing loss and create virtual auditory environments. It also enables us to produce unnatural sounds that can create auditory illusions. All of these features make earphones an invaluable experimental toolContinue reading “Nodal et al. (2010) J Neurosci Methods”

Do humans and neurons adapt to recent sound statistics? When people spend time listening to sounds that come from a very narrow range of locations (statisticians would call this a low-variance distribution), they become very sensitive to even small changes in sound location. On the other hand, if people spend time listening to sounds thatContinue reading “Dahmen et al. (2010) Neuron”

How is sound localization affected by previous experience? Sound localization is an excellent model system for understanding the neural basis of auditory learning and adaptation. In particular, sounds heard previously affect auditory perception at multiple different timescales. This review article summarizes recent advances in our understanding of this topic.

Can ferrets use different sound localization cues? Sound localization relies upon a variety of different cues. For example, when a sound is located on one side of the head, it will be louder in one ear than the other (known as an Interaural Level Difference). It will also arrive earlier at one ear than theContinue reading “Keating et al. (2013) JARO”

What happens to sound localization if you experience hearing loss during development? Approximately 80% of children experience some form of hearing loss before the age of 2. This is commonly caused by ‘glue ear’, which often produces a hearing loss in one ear. Sound localization in the horizontal plane typically relies on differences between theContinue reading “Keating et al. (2013) Curr Biol”

What are the developmental effects of a hearing loss in one ear? The developing brain has a remarkable capacity for rewiring and learning. This review paper outlines recent advances in our understanding of how the developing auditory brain is shaped by experience, considering the impact of asymmetric hearing loss on sound localization. Keating P, KingContinue reading “Keating & King (2013) Front Syst Neuro”

Does experience affect which cues to sound location are used at different sound frequencies? Humans locate low-frequency sounds using differences in the timing of sound heard by each ear (a sound presented on one side of the head takes longer to reach the far ear). At high frequencies, humans rely more on differences in theContinue reading “Keating et al. (2014) EJN”

Can the developing auditory system adapt to hearing loss using multiple adaptive strategies? A hearing loss in one ear changes some of the cues to sound location (the binaural cues that rely on differences between the sound heard by each ear) but leaves others intact (the cues that rely only on the sound heard byContinue reading “Keating et al.
