Neurologger 2
Neurologger 2 is the second version of the Neurologger. Its weight, size and power consumption are approximately 10 times smaller than in the first version. This allows placing the datalogger directly at the head of an animal, even at such small like a mouse. At the same time the computational power of the datalogger is doubled: now it can store 38.4 kilo samples per second (4ch x 9.6 ksps). This allows to store all four channels of tetrode that is very popular in neuronal activity recording.
The minimal weight of the recording combination is 1.285 g only! (It includes: 128MB neurologger board - 0.890 g, two ZA5 35 mAh batteries - 0.345 g, batteries connecting wires - 0.050 g. Not included: head connector, protective cover.)
