Abstract (in Japanese) (See Japanese page) 
(in English) We found that the intracranial natural resonance frequency (NRF) depended only on the intracranial pressure (ICP) and that the relationship between the ICP and the NRF in the brain was able to be calculated using a quadratic function (ICP = 0.0329NRF2 + 0.0842NRF), with an excellent correlation (R2 = 0.9952). Therefore, the individual NRF depends only on the ICP value. Deep learning is effective for countermeasures against artifacts other than the extra-auditory canal pressure waveform (EACPW). These results confirmed that the predicted response using a regression tree model was the most stable and could be applied to new clinical data.
