Recording of electrically evoked responses (100 ms) of a cultured hippocampal network (days in vitro) using two (A, B) different on-chip stimulating electrodes. Even responses below 3 ms can be recorded without electrically induced artifacts.
Both field potentials and multi-unit activities can be sensed in unprecedented spatiotemporal detail on our microelectrode arrays (HD-MEAs). The large field of view on our HD-MEAs enables assays on large tissue portions, such as rat cortico-hippocampal slices or brain organoids, to be carried out.
Functional imaging of distinct inter-ictal (I-IC) events obtained by superimposing the activity recorded from a cortico-hippocampal slice by 3Brain's high-resolution CMOS-MEA with the image of the slice itself taken by a microscope.
Our high-density microelectrode array, or multielectrode arrays (HD-MEAs) are ideal for investigating explanted retinas, thanks to their large-scale sensing areas (up to 5.12 x 5.12 mm2) that feature a temporal resolution which outperforms more traditional imaging techniques.
