Does the method that Transcranial magnetic stimulation effects neurons relate to this out of interest?

I am not familiar with scissors sisters but I know that line from Pink Floyd.

Is this really new? I always thought that this was essentially the implication of the discovery of standing-waves in the brain

They did a cover of the same song. Worth a listen, it's completely different.

I wonder if this validates the Orchestrated Objective Reduction theory of consciousness pioneered by Roger Penrose and Stuart Hameroff. Seems like it would.

What does this have to do with supposed qubits inside neurons?

A bit technical, but some of the most vocal critics of Orch-OR claimed there was no way that quantum states could orchestrate across synapses or between neurons. This quite interesting finding argues otherwise.

Looking at the paper [0], particularly Figure 4, it looks like they cut slices then stick them back together again. This allows the signal to propagate (4.B).

But when a gap of 400 microns is added (4.C), the signal doesn't propagate.

I'm sure that the actual cutting causes some damage, and perfect realignment is unlikely, but I'm not sure how this is conclusive of ephaptic coupling, or how it eliminates the possibility of electrical or chemical communication by synapse, gap junction, or axonal transmission.

When the electrical field potential changes, it changes the probability of neural firing. It's called ephatic coupling. Brain waves (local field potential) aren't just the measured average of the neural firing, but are a signal propagating force. This supports synchronization through entrainment and other resonance effects that are well characterized. Not sure why this is new, but it is great to see it in the news.
