“…Figure 2(c) shows the ERNA distribution according to the Hjorth complexity and frequency. Interestingly, the ERNA frequency estimated by Hjorth parameter lies between 250 and 450 Hz, which is consistent with previous publications [15,30]. This result suggests that Hjorth frequency could be a useful surrogate of ERNA frequency when peak detection fails.…”

“…Previous studies have demonstrated the potential of beta [7,8], high-frequency oscillations [9,10] and gamma-band activity [11], but these spontaneously occurring signals are of small amplitude and are challenging to measure reliably. A recently discovered neuronal signal called evoked resonant neural activity (ERNA) has generated interest among researchers due to its robustness [12][13][14][15]. ERNA is a large neural signal, elicited by DBS stimulation pulses, which resembles a damped sinusoidal waveform (figure 1(b)).…”

“…We performed a statistical analysis to determine whether the frequency response differed significantly between medication states, taking the same approach as in the experimental study [6]. We used a non-parametric cluster-based permutation test with 1,000 permutations at each time point across the 15 different simulations for each medication state.…”

“…ERNA is a series of high-frequency oscillations (HFOs, >200Hz) of high-amplitude in response to 70-180Hz stimulation, despite there being very little to no high frequency activity at the stimulation site pre-stimulation [1] (also see 4 in Fig 2A). ERNA has been observed in different neural structures, but so far only in the pallidal [2,3] and subthalamic regions [1,[4][5][6]. Furthermore, ERNA has also been characterised as a robust response across different devices, patient groups and stimulation conditions [1,[4][5][6].…”

“…from the thalamo-cortical loop in the case of DBS of the subthalamic nucleus). Our models were also not designed to reproduce the dynamic temporal activity that can be evoked by stimulation (such as the evoked resonant neural activity or ERNA in the case of DBS of the subthalamic nucleus [58][59][60]). These limitations should be carefully considered before translational clinical testing.…”
