Stereocyte

**Stereocyte** is a cell type unlocked after completing Friction. It can smell substances based on their left-right difference.

## Description

The Stereocyte looks like a Neurocyte with a pair of sets of seven hairs on its sides.

The Stereocyte can sense other substances like a Senseocyte. However, the difference is that the Stereocyte outputs different signal amounts depending on the direction of the substance, not just its distance. More specifically, the Stereocyte will produce positive amounts of signal if it detects a substance on one side, and negative amounts of signal if it detects the substance on the other side.

Like the Senseocyte, if the Stereocyte detects multiple substances, then it sums up all of the resulting signal productions.

## Usage

Stereocytes are commonly found in smart swimmers which need to know the direction of their targets, be they nutrient pieces or prey.

## Trivia

* This cell looks a Senseocyte that evolved to have all of its 'hairs' in each side.
