The version of the Neurologger used in Africa (Lesku et al., 2011) has improved parameters comparatively to the previously published (Vyssotski et al., 2006).
Now the device has 8GB of storing memory with the possibility of further increase up to 32GB. Simultaneously the device became approximately two times shorter. This became possible due to exploiting of the microSDHC card instead of the standard SD card used before.
The modification of the logger used on ostrichs was equipped with a three-dimentional accelerometer, sampled with the same rate as EEG channels. This version of the logger also can be used just as a 3-D storing accelerometer, if EEG channels are not needed.
The power consumption of this modification is approximately 40% smaller against the original version.
