ABSTRACT: This article provides raw relative electroencephalographic (EEG) power, temperature and activity data from controls and Cav3.2 deficient mice. Radiotransmitter implantation was carried out in male experimental mice under ketamine/xylazine narcosis. Following a recovery period, radiotelemetric EEG recordings from the hippocampal CA1 region were obtained under spontaneous 24 h long-term conditions and post urethane injection. Relative EEG power values (%) for 2 s epochs were analysed for the following frequency ranges: delta 1 ( δ1 , 0.5-4 Hz), delta 2 ( δ2 , 1-4 Hz), theta 1 ( θ1 , 4-8 Hz), theta 2 ( θ2 , 4-12 Hz), alpha ( α , 8-12 Hz), sigma ( σ , 12-16 Hz), beta 1 ( β1 , 12-30 Hz), beta 2 ( β2 , 16-24 Hz), beta 3 ( β3 , 16-30 Hz), gamma low ( γlow , 30-50 Hz), gamma mid ( γmid
