        THE CarlenLab RECEIVES 3.0M € (32.2M SEK) FOR THE PROJECT “Brain circuits in decision-making”    FROM THE KNUT AND ALICE WALLENBERGS FOUNDATION!    

 The project will run over 5 years and be conducted in collaboration with the lab of KONSTANTINOS MELETIS.   The interactions between the prefrontal cortex and the striatum will be studied with large-scale   electrophysiology and calcium imaging in behaving mice.

September 2020

CarlenLab alumni Sofie Ährlund-Richter receives the Brain Diseases Award 2020 from the UZH Foundation for her PhD thesis work ‘On the neuronal correlates of cognition; cell-type specific circuitry and function of the prefrontal cortex!

Congratulations Sofie!

Our study looking at how network asynchrony could underly increased broadband gamma power has been posted on bioXriv. Turns out, as suggested, gamma oscillations as revealed in the LFP does not always reflect a rhythm but can rather be the result of asynchronous and increased firing activities. Furthermore, long-term deficiency of PV inhibition can contribute to desynchronization at multiple time scales.

Our study looking at the role of BDNF-trkB signaling in the adult function of PV interneurons and prefrontal network dynamics has been posted on bioXriv.

The DMCdrive goes live!

Want to long-term record and manipulate neuronal activity in freely moving mice or rats? Then we strongly recommend going for our DMCdrive holding four movable tetrodes + optical fiber, that can be built from 3D printed parts in 4h without much experience. Very reliable optotagging and recovery of single unit and LFP activities over many days.  
Designed by senior researcher Hoseok Kim.

Open access to the publication here.
