Thursday 8th September at 2.00 pm via Teams Details for this talk are below: "Hearing in an acoustically varied world" Abstract: In order for animals to thrive in their complex environments, th= eir sensory systems must form representations of objects that are invariant= to changes in some dimensions of their physical cues. For example, we can = recognize a friend's speech in a forest, a small office, and a cathedral, e= ven though the sound reaching our ears will be vary across these 3 environm= ents. I will discuss our recent experiments into how neurons in auditory co= rtex can form stable representations of sounds in this acoustically varied = world. Our 2-photon calcium imaging studies in ferrets have provided new in= sights into the complex frequency receptive fields of auditory cortical neu= rons, and how these are topographically organized. Our electrophysiological= work has further revealed how complex auditory objects are represented inv= ariantly across listening environments. We use a normative computational mo= del of hearing to examine how the brain may recognize a sound source across= rooms with different levels of reverberation. The model predicted that rev= erberations can be removed from the original sound by delaying the inhibito= ry component of spectrotemporal receptive fields in the presence of stronge= r reverberation. Our electrophysiological recordings confirmed that neurons= in ferret auditory cortex apply this algorithm to adapt to different room = sizes. Our results demonstrate that this neural process is dynamic and adap= tive. These studies provide new insights into how we can recognize complex = auditory objects, even in highly reverberant environments. Biography: Kerry Walker studied Neuroscience as an undergraduate and Maste= r's student in Canada, before moving to Oxford for her DPhil. She is now an= Associate Professor of Neuroscience in the Department of Physiology, Anato= my & Genetics, at the University of Oxford. Her group uses a combination of= behavioural, computational and neurophysiological methods to understand ho= w sounds are encoded in auditory cortex. Her work has provided important in= sights into how pitch is processed by humans and animals, and the importanc= e of the timing of spikes in encoding sound. She is currently looking to hire a Postdoctoral Research Scientist to help = examine how auditory cortical neurons adapt to sound statistics, so please = send her an email if you are interested in joining her group. https://www.dpag.ox.ac.uk/team/kerry-walker Please use the following link to join the seminar on Teams - Click here to = join the meeting<https://teams.microsoft.com/l/meetup-join/19%3ameeting_Mzg= 4YWQ2ZmYtMmNhOS00MzI0LWJhYmItZWRlOTc1ZWY4YTQz%40thread.v2/0?context=3D%7b%2= 2Tid%22%3a%2267bda7ee-fd80-41ef-ac91-358418290a1e%22%2c%22Oid%22%3a%22a04db= 259-744c-438c-a55a-fcb9a68bc359%22%7d> Best wishes, Joe 2.00 pm / 14:00 (BST) 3.00 pm / 15:00 (CEST)) 6.00 am / 06:00 (USA Pacific) 8.00 am / 08:00 (USA Central) 9.00 am / 09:00 (USA Eastern) 9.00 pm / 21:00 (CST/China Standard Time) Dr Joseph Sollini Auditory Circuits Lab Hearing Sciences Mental Health and Clinical Neuroscience, School of Medicine The University of Nottingham W: https://www.nottingham.ac.uk/research/groups/hearingsciences/people/jose= ph.sollini W: https://orcid.org/0000-0002-1974-4291 This message and any attachment are intended solely for the addressee and may contain confidential information.
