Neural Sensors are a rare component that can be found on Jupiter. It is usually found in quantities of 1 - 4. Neural Sensors are most often found by defeating Alad V (Themisto) rather than by killing normal enemies. It can also be found in the Dark Sector mission on Jupiter. As of Update 16.4 Neural Sensors can also drop from Raptor.
