In (a) and (b), the upper four traces represent the LFPs recorded from four channels in the tetrode
T1 implanted in CA1 of hippocampus; the lower four traces represent the LFPs recorded from four channels in the tetrode
T2 implanted in MDT of thalamus; the red vertical lines represent the ending time of stimulation process.
The redundancy (R) of LFP for each tetrode
The model 116FC replaces the 4CX250B ceramic tetrode
, claimed to be the sole provider for the 100 W EMI-EMC test console.
The heart of these power supplies was the self-excited power oscillator using a tetrode
or a pentode with tuned step-up secondary.
It was perhaps inevitable that Hack should move on to Renaissance bronzes and marble--not least those by the 16th-century Netherlandish sculptor Willem van Tetrode

. From the third quarter of the 16th century, this sculpture--illustrated in the January Apollo- was expected to fetch $1.5m-$2.5m, and changed hands--as did many bronzes here--for a figure at the lower end of the estimate, realising just over $2m.
With the apples of the Hesperides behind his back, Tetrode
's tautly posed strongman quivers with dynamic energy, caught in a moment of reflection (estimate $1.5m-$2.5m).
