The headstage is the core element of the system. It houses and heats the MEA, amplifies and digitizes the signals and has an integrated stimulus generator.
MEA2100-headstages are available in different variants. You can either place one 32-electrode MEA, one 60-electrode MEA, one 120-electrode MEA, one 256-electrode MEA, two 32-electrode MEA or two 60-electrode MEAs in the headstage. The contact unit of the MEA-headstage can be changed according to your experimental needs. The rest of the setup is not affected, so changing the contact unit is simple, quick, and cost-effective.
The lid of the headstage can be opened easily and the MEA is placed in the headstage from the top. By closing the lid, the contact pads surrounding the MEA connect to the contact pins.
The built-in amplifier makes sure that the recorded signals are amplified close to the signal source, thereby minimizing noise. The data is then sampled at 50 kHz/channel on all channels simultaneously, ensuring an excellent data quality.
The headstage also provides an integrated stimulator, which can generate current or voltage stimulation signals on 3 independent channels per MEA slot. You can select the stimulation electrodes and design the signal shape via the included software.
For long-term recordings, Multi Channel Systems offers a variety of accessories: You can either cover the ring on the MEA with a semipermeable membrane or place a C02-chamber on the MEA slot. Please talk to your product consultant to find the right solution for your application.
