Making the odorant world intelligible - How its semantics can be characterized

by Aurel A. Lazar

The paper listed below models for the first time the identity of an odorant object as semantic information and the onset/offset timing events as semantic timing. The Functional Logic of Odor Information Processing in the Drosophila Antennal Lobe Aurel A. Lazar, Tingkai Liu, Chung-Heng Yeh, PLoS Comput Biol 19(4): e1011043. https://doi.org/10.1371/journal.pcbi.1011043 <https://doi.org/10.1371/journal.pcbi.1011043> Author summary A major challenge in the study of the Drosophila early olfactory sensory system is to determine how an odorant object (the smell of a rose) is reliably identified in the face of fluctuations of the concentration amplitude of the molecules within the odorant plume. More fundamentally, the question arises how semantic information, often associated with subjective perception, can be characterized. To address this challenge, we leveraged the unique combinatorial odorant code of Drosophila and presented a formal treatment of the identity of an odorant object as its semantic information (or semantics for short). Grounded in the physiology of the fly brain, we identified the functional roles played by Local Neurons in the fruit fly Antennal Lobe in the recovery of the semantics and the onset/offset timing information (or semantic timing). Our model of the Antennal Lobe circuit is built with a highly versatile canonical model of neural computation - the differential Divisive Normalization Processor.

Postdoc at Leiceseter University, UK

by Quian Quiroga, Rodrigo (Prof.)

We are looking for a postdoc to study single cell recordings in humans, performed in epileptic patients for curative surgery. The project will investigate concept cells (a.k.a. Jennifer Aniston neurons) – that means, neurons in the hippocampus and surrounding areas that selectively fire to specific concepts, like different pictures and the written or spoken name of a particular person (e.g. Quian Quiroga et al, Nature 2005; Quian Quiroga, Cell 2019), which are involved in declarative memory functions. For more details see: https://web.archive.org/web/20220108024112/https://www2.le.ac.uk/centres/cs…<https://web.archive.org/web/20220108024112/https:/www2.le.ac.uk/centres/csn…> The successful candidate will contribute to performing recordings with patients and the analysis / modelling of the data to investigate the role of these neurons in memory. The candidate should have very good quantitative skills (data processing and programing e.g. in Matlab) and a strong background or interest in neuroscience. Informal enquiries are welcome and should be made to Prof. Rodrigo Quian Quiroga (rqqg1(a)le.ac.uk) For more details and to apply, please use this link: https://jobs.le.ac.uk/vacancies/7756/research-associate.html The closing date for the applications is 5th May 2023.
