Fast z-galvo for 3D two-photon imaging

Perhaps you’re familiar with the various AOD and piezo-based methods for two-photon imaging in 3D quickly. Here’s another way (Botcherby et al. 2012, PNAS, open access)

The used all galvos, rather than AODs or…



Intrinsic imaging on the cheap

Intrinsic signal optical imaging is a functional imaging modality where the reflectance of red light indicates active portions of cortex. It is used for many applications, including imaging individual barrels in rodent somatosensory cortex, maps in visual cortex, and the tonotopic organization in auditory cortex.

Here is a prior Labrigger post with tips for intrinsic…



Clearing tissue for imaging: index matching is not new

The main factor that limits how deep we can image into tissue is the scattering of light. Multiphoton imaging partially mitigates the problem by using infrared light, which scatter less, and by using an…



The Elsevier Boycott and the Research Works Act

Perhaps you’ve heard about the Elsevier Boycott aka the Cost of Knowledge. I’m not going to rehash the problem we all know so well. But here are a few links I wanted to…



Predatory open science funding

There are some open access journals that seem to have relativley loose editorial standards. And by “editorial” I mean “ethical”, and by “relatively loose”, I mean “no”. These publishers have been called “predatory”…



Open Microscopy Environment, for managing microscope images

The Open Microscopy Environment (OME) is a group of programmers, from academia and industry, who put together open source software packages for managing microscopy data. The emphasis is on handing multiple image formats,…



OpenElectrophy – for multielectrode recordings

OpenElectrophy is a somewhat mature, actively developed, open source program for analyzing data from multielectrode recordings. It makes heavy use of Python and SQL and is developed by a team of French researchers…



3D Sketch-up models for Newport parts

Thorlabs and Newport have offered 3D models of their products for a long time. However, they’re typically in formats for expensive programs like SolidWorks and AutoCAD. In the past year or two, Newport has been slowly adding to their library of Google SketchUp models.



Competition

Like many of you, I went to monster truck show last weekend.

The competition reminded me MATLAB’s new thing: Cody.

It’s a bunch of problems posed as MATLAB coding tasks. For example:

Find the mean…



MATLAB command locateVal

In two previous posts I shared some MATLAB code to help design collection optics in 2p scopes.
Collection optics for 2p scopes, post 1
Collection optics for 2p scopes, post 2
It was just brought to my attention that I didn’t include the command locateVal in the code I posted. It’s a very…



BCG Matrix

Here’s a BCG Matrix for scientific papers. One paper is plotted on the graph. At Nature’s Action Potential blog, the editor explains why they accepted it….

Spectra viewing app for iOS

Zeiss released an iOS app for viewing spectra.

No Android version yet, but Johannes Amon said:

of course I can’t tell you any specifics but at the moment we are evaluating a…
