In two 1926 articles, Edgar Douglas Adrian revealed that neurons communicate through trains of spikes. @carandinilab.net describes the remarkable discovery and how it shifted focus from the medium (the nerve) to the message (the neural code). #neuroskyence www.thetransmitter.org/history-of-n...

Related to the #NobelPrize in #Optogenetics: I'm reflecting on the question "who invented X?" in science. 10 years ago I wrote about the people who were working on optogenetics, the patent debates and the role of race and prestige. I don't know the answer, but... www.statnews.com/2016/09/01/o...

He may have invented one of neuroscience’s biggest advances. But you’ve never heard of him
The saga of Zhuo-Hua Pan, perhaps the rightful inventor of optogenetics, raises the question of what it means to invent something in science.

a good summary of how we got here and what it means. i would add is that everyone who works with the fly connectome datasets knows that they all far from "complete". each one, though monumental, has major reconstruction/annotation issues, not to mention the lack of a peripheral nervous system.

The superposition of these two studies — both incredible — reflect a snapshot of "one big thing" systems neuroscience has yet to resolve. In mice: 1. Task-related signals are everywhere. 2. Absent large swaths of "everywhere," suprisingly sophisticated learning & behavior remains.

Mandatory reviews by top health officials and checks for 235 disfavoured terms have left hundreds of vetted grant applications in administrative limbo.
