Brain waves are a repetition of a pause and an activity
Chika Koyama
Brain waves still cannot reliably distinguish between awake and asleep states. Here, I present new original indices, voltage subthreshold wave and abovethreshold wave burst, fo…
Microwave amplitude reflecting instability of LFP electrode ground field is useful for consciousness state identification
Chika Koyama, Taichi Haruna, Kazuto Yamashita
We recently developed original electroencephalogram indices focusing on microwaves of flattish period (named ), which correlated with volatile anesthesia concentration in dogs.…
Power-law distribution in Burst-suppression on electroencephalogram of dogs
Chika Koyama, Taichi Haruna, Satoshi Hagihira +1
Burst-suppression (BS) is a reliable electroencephalogram (EEG) indicator of excessive deep anesthesia common in mammals. Since some intermittent events are known to follow a power…
New EEG parameters correlated with sevoflurane concentration in dogs: tau and burst
Chika Koyama, Taichi Haruna, Satoshi Hagihira +1
Background: Electroencephalographic (EEG) indicators for anaesthesia depth are being developed. Here, we propose novel EEG parameters created by using two kinds of waveforms discri…
