News

Here I will let you know about new and exciting things that happen around science and research. Have a look into the archive to find older news or things that you might have missed.

+ Travel to SfN and APAN (Nov 11th to 16th) in a few days (2016-11-05)

I am leaving for SfN in a few days. SfN is in San Diego this year with APAN just prior on the 11th. I will present my poster on the first day of SfN (12th) in the afternoon session (1-5pm). I present data showing that an individual's attentional state modulates the influence of an irrelevant stimulus dimension on perception of another stimulus dimension. You can have a look at my poster here.

+ Collaborative work with Purdue friends got accepted (2016-10-31)

I am very pleased that the European Journal of Neuroscience has accepted our latest work. Together with Ed Bartlett (Purdue University) and Aravind Parthasarathy (now at Harvard Medical School) we investigated the effects of aging on neural synchronization in the inferior colliculus in rats. We show a relative gain in onset responses as well as in synchronization strength (for amplitude-modulated sounds with a slow modulation rate) from local field potentials (synaptic input) to spiking (output) in older rats. We also observed a decrease in neural synchronization for older rats at higher modulation rates. We discuss our data in the context of age-related changes in the excitation-inhibition balance.

More information will be available soon.

+ New tutorial on linear-nonlinear models (2016-07-09)

I have just finished a new tutorial on linear-nonlinear Poisson models. Since I had trouble understanding these models for forever (and still have for some aspects of it), I thought a simple tutorial explaining step-by-step the main stages involved as well as providing matlab code along with it might help somebody who is new to the topic and wants to get started.

You can find the tutorial here.

+ Awesome! Neurobiology of Aging accepted my recent work (2016-05-08)

In the manuscript titled "Altered Temporal Dynamics of Neural Adaptation in the Aging Human Auditory Cortex" we show that aging goes hand in hand with an increased auditory cortex response magnitude, reduced response variability, a larger dynamic response range, and reduced sensitivity to temporal context. Modelling neuronal activity suggested that neurons in the aged auditory cortex recover faster from adaptation, leading to the observed age effects.

+ Wöstmann, Herrmann, Maess & Obleser just accepted in PNAS (2016-02-26)

Title: "The spatiotemporal dynamics of auditory attention synchronize with speech" will be available in PNAS soon. Here we show that the spatio-temporal modulations of alpha power are predictive of speech recognition in a multi-stream situation.


Research opportunities

I am currently a postdoc in the lab of Dr. Ingrid S. Johnsrude at the University of Western Ontario (Canada). We are often looking for interested and motivated undergraduate volunteers who are excited to gain experience in research and science. Please check out the lab webpage for further information.
