As you all know, if you have a small field-of-view (FOV), you can often get better quality data than with a larger FOV. Dwell times per pixel are higher, more pixels per cell, higher frame rates, and ultimately more photons per second per neuron. That’s…

Technology moved so slowly for so long, and then around the Industrial Revolution we all become accustomed to technology moving very…
1: Are you getting enough photons/s/cell ?
Select an indicator.
Determine what you want to measure: Do you need to see every spike? Or is detecting bursts enough?, and what …
This comment by Ryan Cooper came to me from Mark Histed. It has stuck with me, and Mark has repeated the idea a few times. For years now, I’ve been…

I’ve posted a couple of times about Typst (some tips to get started, and why I like it over Word and LaTeX). I was happy to…
I saw this post, with this quote: “High-resolution activity maps of PFC did NOT align with cytoarchitecturally defined subregions.” Is this a profound, provocative finding that provides strong evidence for the irrelevance of cytoarchitecture?
When you publish a paper on a new imaging system, people often want to compare figures of merit. Field-of-view, resolution, speed, etc. They want to know in what ways your…
Maybe you learned that his name was Snell. It wasn’t.
Let me back up. Electromagnetic waves propagate at about 3 x 10^8 meters per second in vacuum. We often call that number “c“. When those waves have frequencies around 400 – 800 terahertz, we call them visible light.
When those waves go through…
This handbook is available for free online. Here’s the link.
There is much evidence that updates to factual beliefs, even if successful, may not translate into attitude or behaviour…
There are always people who complain loudly that they are unconvincing. They won’t say it that way, though.
Instead, they might blame suppression of speech, or a conspiracy, or people being…
It’s right there in the name of this blog. A double entendre: (1) for experimental apparatus rigs and the people who build them, aka “riggers”; and (2) rigor, an important…
I have a little piece I often reuse, it goes something like this.
We know that visually guided navigation is a hard problem even for state-of-the-art AI because…
I came across this cool minimal synth kit called Labor from Erica synths. It’s great for learning about circuits and signal processing. There are videos online…
One time, years ago, I was asked (by a very nice person and an accomplished scientist) to write a book chapter. I didn’t want to. But I was working with a brilliant postdoc who…
