Our article “Neuronal On- and Off-type heterogeneities improve population coding of envelope signals in the presence of stimulus induced noise” has been published in Scientific Reports. In this paper we describe a novel type of correlated variability which we term “noise response similarity” which can be induced through natural stimuli with complex stimulus structure (i.e independent 1st and 2nd order stimulus attributes). Enjoy the read!

Today my contribution “Information transmission in the electrosensory pathway benefits from reduced correlated variability in heterogeneous On- and Off-type populations” to the upcoming CAN meeting (May 31st – June 3rd). See you at Place Bonaventure…
Our article “Neural synchrony gives rise to amplitude- and duration-invariant encoding consistent with perception of natural communication stimuli” is now in press at Frontiers in Neuroscience Perception Science as part of the special issue/research topic “Understanding the Importance of temporal coupling of neural activities in information processing underlying action and perception”.
In this article we extend on our earlier findings that correlated (or synchronous) activity
Our article “Task related sensorimotor adjustements increase the sensory range in electrolocation” was just accepted for publication in SFN’s Journal of Neuroscience. This project which I had started during the late stages of my time at Bielefeld University used a classical behavioral paradigm to train Gnathonemus petersii in a object detection task. In contrast to the classical paradigm however, Continue reading “PAPER in Journal of Neuroscience”
My mini-review “Novel functions of feedback in electrosensory processing” was just accepted for publication in Frontier in Integrated Neuroscience. In this review we discuss different feedback pathways in the electrosensory medullar and their role and impact on electrosensory processing. We focus on novel, more recently discovered role of the so called direct feedback that is topographically ordered and takes part in transformations of the neuronal code that are crucial for generating firing rate responses to behaviorally relevant stimuli.

Everyone of us has groaned over submission and high publishing fees. Or about trying to get access to that one publication that was published in a book or a journal that the library has not subscribed to.
This article discusses some of the background of the oligopolistic publishing industry and different methods to reduce and overcome paywalls.
Our new Neuropixels probes have arrived. These are fully integrated silicon probes with over 900 active sites and the possibility to do simultaneous extracellular recordings from over 300 sites – check them out here. We hope that this will drive our investigations regarding population coding and correlated variability to the next level.
At the moment… Continue reading “NEUROPIXELS are here!”
Along my co-author Maurice Chacron, I was invited to write a dispatch article highlighting the just published paper “Closed-Loop Control of Active Sensing Movements Regulates Sensory Slip” by the groups of Noah Cowan and Eric Fortune. In their paper the authors developed an augmented reality setup for electric fish enabling them to manipulate the sensory feedback that animals perceive during active sensing movements. Our article “Active Sensing: Constancy requires change” can be found here – I hope you enjoy the read!
Frontier in Integrated Neuroscience has accepted our new paper “Population coding and correlated variability in electrosensory pathways” for publication. In this manuscript we review the state or the art knowledge regarding the presence, origins and impact of neural correlations onto the encoding of electrosensory signals in Apteronotoids. We review both correlated firing due to exegeneous signals as well as correlated variability, its potential impact on signal encoding and its plasticity in the electrosensory pathway. Enjoy!
