Mice were anesthetized with an IP injection of ketamine (100 mg/kg) and xylazine (10 mg/kg), and then placed in a sound-isolated and electrically shielded sound booth (Kahntact, Hillside, IL, USA).
The ABR measurement (PNS 2, Tübingen, Germany) was done in an electrically shielded sound attenuated chamber for the frequencies 4, 8, 16 and 32 kHz.
Participants performed the experiment in an electrically shielded, sound-attenuated, and dimly lit cabin (IAC, Niederkrüchten, Germany).
The experiment was performed in an electrically shielded, sound-attenuated, and dimly lit cabin (IAC, Niederkruchten, Germany).
31 Scalp EEG was recorded in an electrically shielded sound-attenuated chamber using Ag/AgCl electrodes in the international 10/20 montage.
The experiment was conducted in an electrically- and sound-shielded room under dim lighting conditions.
The EEG was recorded from 128 Ag-AgCl electrodes positioned on the scalp with a BioSemi Active-Two amplifier system in an electrically shielded and sound attenuated room.
Participants were comfortably seated in an electrically shielded and sound attenuated room.
Stimuli were presented in an electrically shielded and sound-attenuated room (reverberation time.3 s, background noise level 43 dB) with the sound pressure level of 75 dB via two loudspeakers (Genelec® 6010A, Genelec Ltd., Iisalmi, Finland).
