Starting Point CalculationDepth to target is from alignment adapterOffset calculates for FHC stackupAllowable targeting range is 150-180mm
FHC Calculation
FHC AssemblyRemove alignment adapterInsert Center positionerAttach drive baseAttach micro-driveNote: be sure drive is set to starting depth
Cannulae insertionInsert stylet through passing cannulaAttach collet to passing cannulaPass cannula/collet combo into driveRemove StyletInsert microelectrode cannulaNote: be sure drive is set to starting depth
