Preamplifier bandwidth & two ways of counting photons

Posted on September 20, 2016 by P.T.R. Rupprecht

For two-photon point scanning microscopy, the excitation laser is typically pulsing at a repetition rate of 80 MHz, that is one pulse each 12.5 ns. To avoid aliasing, it was suggested to synchronize the sampling clock to laser pulses. For this, it is important … Continue reading →

Deep learning, part IV: Deep dreams of music, based on dilated causal convolutions

Posted on September 13, 2016 by P.T.R. Rupprecht

As many neuroscientists, I’m also interested in artificial neural networks and am curious about deep learning networks. I want to dedicate some blog posts to this topic, in order to 1) approach deep learning from the stupid neuroscientist’s perspective and 2) to get a feeling … Continue reading →

Whole-cell patch clamp, part 1: introductory reading

Posted on September 4, 2016 by P.T.R. Rupprecht

Ever since I my interested in neuroscience become more serious, I was fascinated by the patch clamp technique, especially applied for the whole cell. Calcium imaging or multi-channel electrophysiology (recent review) is the way to go in order to get an idea what … Continue reading →
