Applicable situation: Combining the tetrode electrode with the drug delivery tube to realize the analysis of a single neuron under different pharmacological conditions, using a 0.38mm diameter cannula to reduce the damage caused by implantation and improve the success rate of signal acquisition.
General parameters: The tetrode electrode wire is 20um nickel-titanium alloy wire, the length is 5mm/8mm, and the length of the drug delivery tube is 300/500um shorter than the electrode wire.
The number of channels, size and other parameters can be customized according to actual needs
