Exactly. I should know better and I got caught up in the excitement of "neurons editing their DNA". The Hopkins press release department was either clueless or trying to make this paper sexier than necessary. The Tet3 finding is c

I also noticed the lack of a "double dissociation" study. Fwiw there's a ton of studies right now using optogenetics to transiently "lesion" areas where the authors have not done double dissociation type experiments

This paper doesn't describe "traditional" methods. The author test analyses used today . The first simulation specifically tests whether inactivating "cells" (components in the microprocessor) can let us make causa

You have a point. It would be interesting for you to plot the data, or ask the author to plot the data, with rankings of party members, so we could see whether your hypothesis is true. Hypothesis: Politifact gives more "pants-on-fire&q

Thank you for posting this. It is a bit mistaken to say "neuroscientists haven't scrutinized their brains" when people like Harvey Karten (one of the authors on the paper at that link) have dedicated their lives to studying t

jacquesm is right, there's no actual scientific breakthrough here. We already know glutaraldehyde does a good job of preserving synaptic structure, that's why we have used it to fix brains for electron microscopy analysis for roug

Check out the work of Steve Potter's group at Georgia Tech. They culture rat cortical neurons in a dish while recording and stimulating them in a closed loop system. They did some studies with using these hybrid systems to control robo

She totally does say they're cortical neurons. But it seems the point of the article is that most of the brain is dormant. I'm not sure that most of the brain is dormant.

It would be interesting if active neurons were suppressing memories but I don't know of any evidence in support of that idea. Most of the articles cited by the author don't deal with neurons that are directly involved in memory. T

What this article leaves out is that sparse coding is most common in neocortex (the wrinkly outside part of your brain). In structures underneath there are a lot of brain cells that fire away all the time: the thalamus, the basal ganglia, t

Just want to point out that there could be a wide range of ability to recognize faces and it's probably realy hard to find a good measure of that. If someone shows you a picture of your wife (to take an example from one comment) and a

Have you ever mistaken "color TV static" for a king penguin? If not, then your built in DNN does a good job of discriminating between them. There are optical illusions that mess with our visual system, of course. You could I guess

There's definitely selective responses in single unit recordings, even upstream of sensory neurons in "higher" areas; look for articles on the "Jennifer Aniston cell" and on so-called mirror neurons. The question is
