Sunday soundbites: Monday edition

Advances in making an artificial retina.

Why is EEG under-rated? Because there's no pretty brain picture.

Do we need a new enlightenment? I'm not sure, but this is a very cool video.


  1. EEG has been around for nearly 100 years. Apparently, the lack of spatial localization is a pretty big issue. fMRI at least holds the potential to be combined with small molecules and contrast agents to increase spatio-temporal resolution, as well as, being used to measure neurotransmitter levels directly.

  2. Depends on what your goal is. If you're trying to work out a particular large-scale network, but are correct. BUT, even with 1mm^3 voxels, your spatial resolution still isn't that great and the time course of the BOLD response is pretty uninformative.
