How to do science according to Ardem Patapoutian
Ardem Patapoutian is a neuroscientist who works on the molecular basis of sensation via mechanosensitive ion channels. In 2021, he was one of the recipients of the Nobel prize, at a relatively young age. He has since used his influence … Continue reading

A collaborative review on error signals in predictive processing
Predictive processing is one of the most influential ideas from computational neuroscience for the experimental neurosciences. However, definitions of predictive processing vary broadly, to the extent that “predictive coding” is used sometimes in a very narrow sense (there are specific … Continue reading
Four interesting papers on astrocyte physiology
A review of four interesting recent papers on astrocyte neuroscience: (1) Norepinephrine Signals Through Astrocytes To Modulate Synapses (2) A spatial threshold for calcium surge (3) Network-level encoding of local neurotransmitters in cortical astrocytes, and (4) Continue reading

There is no recipe for discoveries
There is no recipe for discoveries, and there is no cookbook on how to publish a paper. But at least there are typical events and routes that are often encountered. Here, I’d like to share the trajectory of a study … Continue reading

Three recent interesting papers on computational neuroscience
Three papers:
1. The Neuron as a Direct Data-Driven Controller
2. A learning algorithm beyond backpropagation
3. Continuous vs. discrete representations in a recurrent network Continue reading
Improving the resonant scanner’s sync signal using a phase locked loop (PLL)
Calcium imaging with two-photon point scanning is the technique to chronically record from identified neurons in the living brain of animals. The central piece of two-photon point scanning microscopes is a scan engine. This can be a complex optical device … Continue reading

Two random but interesting papers on neurophysiology with behavior
Bagur, Bourg et al. (2022) from the Bathellier Lab in Paris make the interesting finding that the auditory code is represented as temporal sequences of neuronal activity in early auditory processing stages and as spatial patterns in auditory cortex. I … Continue reading
Interesting papers on behavioral timescale synaptic plasticity (theory)
Behavioral timescale synaptic plasticity (BTSP) is a form of single-shot learning observed in hippocampal place cells in mice (Bittner et al., 2015, 2017). This finding is both interesting and inspiring for computational neuroscience for several reasons. In the first place, … 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
