Using combined TMS and intracranial EEG in two neurosurgical patients, we showed that single TMS pulses caused brief, transient suppression in high-frequency activity (HFA), generally considered to be reflected of population-level spiking. Sham stimulation showed no effect. 3/

Would love some insight into what has happened to @nytimes.com. Is a president embroiled in a child sex trafficking scandal with underwater poll numbers on a "winning streak"? Is Trump usually cool, calm, and collected, only now "displaying his volatile side"?

We were surprised to find that, despite anticorrelated HFA signals, TMS seemed to increase phase-locking in lower frequencies (alpha and theta) between sgACC-DLPFC. Could this be a mechanism by which the DLPFC influences sgACC activity? 4/

HFA signal in the sgACC was inversely correlated with HFA signal in the DLPFC, meaning that as DLPFC activity increased following TMS, sgACC activity decreased. This mirrors what we’ve known from fMRI for a long time, but now shown with direct in-vivo measures of neural activity. 3/

Stimulation to the DLPFC may tamp down an overactive sgACC and relieve symptoms of depression. By stimulating the DLPFC with TMS in two neurosurgical patients with electrodes implanted within the sgACC, we found a reduction in high-frequency neural activity – a correlate of population spiking. 2/

Pollan manifests the inverted thinking that psychedelic evangelists have: "The science will eventually conform to what I know to be true" instead of "what I know to be true comes from the science." It's the same twisted logic of the anti-vaxxers that Pollan (rightly) refutes!
