Brains are assets that exist in your project folder. The Ball3DAgents are connected
to a Brain, for example : the **3DBallLearning**.
A Brain doesn't store any information about an Agent, it just
As of v0.6, a Brain is a Unity asset and exists within the `UnitySDK` folder. These brains (ex. **3DBallLearning.asset**) are loaded into each Agent (ex. **Ball3DAgents**) object. A Brain doesn't store any information about an Agent, it just
returns the chosen action to the Agent. Thus, all Agents can share the same
Brain, but act independently. The Brain settings tell you quite a bit about how
returns the chosen action to the Agent. All Agents can share the same
Brain, but would act independently. The Brain settings tell you quite a bit about how
Create -> ML-Agents -> Brain`. There are 3 kinds of Brains :
The **Learning Brain** is a Brain that uses a Neural Network to take decisions.
When the Brain is checked as `Control` in the Academy **Broadcast Hub**, the
external process will be taking decisions for the agents
and generate a neural network when the training is over. You can also use the

The **Learning Brain** is a Brain that uses a trained neural network to take decisions.
When the `Control` box is checked in the Brains property under the **Broadcast Hub** in the Academy is checked as `Control`, the external process will be take over making decisions for the agents

of Brains do what you need, you can implement your own Brain.
