This performance is driven by a high-performance spatial recording characteristics, which allows for a more accurate identification of neuronal spikes.
The thin, Stainless Steel shaft of the probe contains 7 Platinum/Iridium electrodes, from which the middle one (tip electrode) is symmetrically surrounded by the 6 others. The Heptode Magic Pencil is characterized by low impedance value and remarkable signal-to-noise ratio (SNR). It is ideal for pre-clinical recordings.
Due to its shape, the Heptode Magic Pencil has the benefit of easy dural penetration resulting in minimal tissue trauma. For larger animals, such as primates a guide tube may be recommended for puncture.

It may be possible to produce this probe beyond the listed parameters to facilitate the most ideal setup for your research needs. We can also build either capillaries (acute only) or fibers into the Heptode Magic Pencil for local drug delivery and optogenetical studies, respectively. Multiple connector types are available too for providing easy connection to your data acquisition system.
