Interesting papers on behavioral timescale synaptic plasticity (experiments)
Behavioral timescale synaptic plasticity (BTSP) is a form of single-shot learning observed in hippocampal place cells in mice (Bittner et al., 2015, 2017). The idea is that post-synaptic activations (“eligibility traces”) are potentiated by a dendritic plateau potential/burst (“instructive signal”) … Continue reading
Interesting papers on recent neuroscience methods
Find below three interesting methods papers relevant for neuroscience. All three of them are, in my opinion, worth a quick read. Acoustic cameras to localize ultrasound vocalization of mice Sterling et al. (2023) from the lab of Bernhard Englitz addressed … Continue reading

Interesting papers on online motion correction for calcium imaging
In a living animal, the brain is moving up and down in the skull. This brain motion can be due to breathing, heartbeat, tongue movements, but also due to changes of posture or running. For each brain region and posture, … Continue reading

The idea for a journal “eLife-A”
The process of publishing and reviewing scientific results is often a strange and difficult-to-navigate landscape. It would take too long to mention all the problems and pitfalls related to publishing. For example: overly high publication charges; long turnaround times for … Continue reading
Annual report of my intuition about the brain (2022)
How does the brain work and how can we understand it? To view this big question from a broad perspective at the end of each year, I’m reporting some of the thoughts about the brain that marked me most during … Continue reading
“Laser Scanners” by William Benner
William Benner is a scanner enthusiast and the president of the company Pangolin. His company sells equipment mostly for laser shows but also for other applications. Some years ago, he wrote a book on “Laser Scanners”, which is available through … Continue reading
Ambizione fellowship and an open PhD position
I’m glad to share that I am going to start my own junior research group at the University of Zurich in March 2023! As an Ambizione fellow, I will receive funding for my own salary, some equipment, consumables and a … Continue reading

Self-supervised denoising of calcium imaging data
This blog post is about algorithms based on deep networks to denoise raw calcium imaging movies. More specifically, I will write about the difficulties to interprete their outputs, and on how to address these limitations in future work. I will … Continue reading
