In view of the above, I have decided to drastically simplify the design of Animal’s brain. I am taking out the association and sequence detection layers. They are not needed, in my opinion. Sequence detection is required only for variable time-scale sequences, which do not exist in Animal’s sensory environment. As a result, Animal’s brain design will be reduced to the following:
- Sensor Layer
- Sensory Cortex (signal separation)
- Memory Layer (working memory)
- Motor and Motivation Layer
- Effector Layer
The memory layer is strictly working memory with a seven-item capacity (seven eyes). The function of an eye is to maintain an action cell alive for a short time.
An action cell consists of two neurons, a predecessor and a successor. The motor layer creates and manages all the action cells and organizes them into behaviors or action sequences. It receives input signals directly from the separation layer (sensory cortex) and channels them immediately to the effector layer. This is the most complex cell assembly in Animal’s brain. It handles motor conflict resolution, motivation (reinforcement learning) and anticipation. I’ll let you know how it all works out.
