(Electronic Auditory Research Seminars) From: "Vogler, Nathan" <Nathan.Vogler@xxxxxxxx> Date: Tue, 8 Feb 2022 16:48:08 +0000 --_000_MN2PR04MB612702BE99D5689DE6B6BE18C82D9MN2PR04MB6127namp_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Dear fellow neuroscientists, We would like to invite you to join us on Tuesday, February 22 at 1:00 pm E= ST (UTC-5) for the next edition of E.A.R.S. (Electronic Auditory Research S= eminars), a monthly auditory seminar series with the focus on central audit= ory processing and circuits. Please pre-register (for free) and tune in via= Crowdcast (enter your email to receive the link for the talk): https://www= .crowdcast.io/e/ears/15 (Note: for optimal performance, we recommend using Google Chrome as your br= owser). Dr. Ioana Carcea (Rutgers University) * "Social transmission of behavioral responses to distress calls" * Maternal care, including by non-biological parents, is important for = offspring survival. Oxytocin, which is released by the hypothalamic paraven= tricular nucleus (PVN), is a critical maternal hormone. In mice, oxytocin e= nables neuroplasticity in the auditory cortex for maternal recognition of p= up distress. However, it is unclear how initial parental experience promote= s hypothalamic signalling and cortical plasticity for reliable maternal car= e. We continuously monitored the behaviour of female virgin mice co-housed = with an experienced mother and litter. This documentary approach was synchr= onized with neural recordings from the virgin PVN, including oxytocin neuro= ns. These cells were activated as virgins were enlisted in maternal care by= experienced mothers, who shepherded virgins into the nest and demonstrated= pup retrieval. Virgins visually observed maternal retrieval, which activat= ed PVN oxytocin neurons and promoted alloparenting. Thus rodents can acquir= e maternal behaviour by social transmission, providing a mechanism for adap= ting the brains of adult caregivers to infant needs via endogenous oxytocin= . Dr. Liberty Hamilton (University of Texas at Austin) * "A parallel pathway for speech that bypasses primary auditory cortex" * A prevailing view of information flow through the auditory pathway po= sits that speech sounds are processed through a hierarchy from brainstem to= thalamus to the primary auditory cortex and out to speech cortex on the su= perior temporal gyrus. Using a combination of high resolution ECoG grid rec= ordings across the lateral superior temporal gyrus (STG) and core auditory = areas on the temporal plane, cortical stimulation, and ablation, we show th= at this may not be the case. Instead, we find an area of the posterior STG = that is activated in parallel to the primary auditory cortex at indistingui= shable latencies. Stimulation of the primary auditory cortex does not appea= r to interfere with speech perception, which would be predicted if it provi= ded the sole inputs to this area. I will discuss these results and implicat= ions for brain processing of speech. ***Additionally, we are currently seeking applications from trainees intere= sted in presenting their work in our upcoming Trainee Session on March 22. = Please complete this form to apply by February 22: https://forms.gle/iW2dabEzah1eLQpWA The application is also available on our website<https://sites.google.com/v= iew/ears2020/home>.
