g.HEADstage: Specs & Features
miniaturized headstage amplifier system for single neuron spike recording with g.USBamp or g.HIamp
g.HEADstage - g.tec's miniaturized pre-amplifier
The g.tec 16-channel head-stages allow the recording of action potentials/spikes with g.HIamp or g.USBamp. The boards are extremely small and lightweight and are connected via a very flexible cable to amplifier. This allows the animal to move with almost no restrictions. The electronic system has an extremely low noise level and very high input impedance for high quality recordings. The channels have very similar gain, and therefore a very high Common Mode Rejection Ratio is obtained. The head-stages can also be used for biosignal recordings like EEG or ECG in animals.
g.HEADstages are available with system connectors or with single channel connectors that can be interfaced to electrodes/wires easily. The head-stages are connected to the g.SPIKEsens power supply and filtering box that is connected to the amplifier. One g.SPIKEsens box supports up to 16 channels. Several head-stages can be used simultaneously. The g.SPIKEsens box filters the signal between 0.5 Hz and 6000 Hz. Voltage Noise Density at 1 kHz is only 10 nV/SQRT(Hz). Aggregation boards can be used to interface the head-stages with different electrodes like twisted wires, silicon electrodes and/or multi-electrode arrays.
An important feature of the head-stages is that the flexible cable can be disconnected. This allows you to replace the cable if it is destroyed by an animal or other cause.
The g.HEADstage is offered in two different types:
- The multi-pin headstage
- The golden-pin headstage
- Extremely small board (16 channels: 23 mm x 23 mm)
- Low weight (<3 g)
- Aggregation boards help interface different electrodes types
- High quality neuronal activity recordings
- LED slot to support easier video tracking
- Very high signal-to-noise ratio
