NEUROLOGGER®

Animal-attached Neurologger records behavior and electrophysiological data into its own memory.

Neurologger 1

	For large animals 8 differential neurophysiological channels (EEG, ECG, EOG, EMG) three of which can be used for 3-D accelerometer 5.31 g recorder weight + ~9 g typical battery replica handbags Total weight about 15 g without enclosure

Smallest in the world battery-powered optogenetic stimulator

Only 0.59 g including the battery and one light emitter
Ideal for small laboratory animals (mice, rats, etc.) and songbirds (zebra finches, canaries, etc.)
Supports up to 4 independently controlled light emitting diodes (LEDs)

Neurologger 2A/2B with integrated 4-channel optogenetic stimulator

Records brain activity (4 channels up to 33 kHz sampling) together with activation or suppression of up to 4 brain areas
Designed for use with mice, rats and other laboratory animals

	Records neuronal brain activity and indoor positional data Simultaneous tracking of multiple animals is possible. Sub-centimeter accuracy of position determination Fast sampling rate of position Head/body orientation is recorded
