Improving the resonant scanner’s sync signal using a phase locked loop (PLL)

Posted on October 19, 2023 by P.T.R. Rupprecht

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

Posted on October 15, 2023 by P.T.R. Rupprecht

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)

Posted on October 6, 2023 by P.T.R. Rupprecht

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 online motion correction for calcium imaging

Posted on September 4, 2023 by P.T.R. Rupprecht

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 →
