BELBIC - Brain Emotional Learning based Intelligent Controller

BELBIC is considered as one controller which adopts the network model based from Moren and Balkenius.It is stated that some parts of the brain is responsible for our emotions.
The limbic system is comprised of four main structures: the amygdala, the hippocampus, regions of the limbic cortex and the septal area. These structures form connections between the limbic system and the hypothalamus, thalamus, and cerebral cortex. The hippocampus is important in memory and learning, while the limbic system itself is central in the control of emotional responses.

  • Amygdala - Almond shaped structure mass of nuclei.The primary roles in the formation and storage of memories associated with emotional events.
  • Orbitofrontal Cortex - A prefrontal cortex region in the frontal lobes in the brain which is involved in the cognitive processing of decision-making.The human OFC is among the least-understood regions of the human brain; but it has been proposed that the OFC is involved in sensory integration, in representing the affective value of reinforcers, and in decision-making and expectation
  • Thalamus - It is situated in the Midbrain and is responsible for processing and relaying movement and sensory information.
 Emotional Learning

Traditionally, the study of learning in biological systems was conducted at the expense of overlooking its lesser known counterparts: motivation and emotion.Motivation is the drive that causes any system to do anything – without it, there is no reason to act. Emotions indicate how successful a course of actions have been and whether another set of actions should have been taken instead – they are a constant feedback to the learning system. Learning on the other hand, guarantees that motivation and emotional subsystems are able to adapt to constantly changing conditions.Every creature has innate abilities that accommodate its survival in the world. It can identify food, shelter, partners, and danger. But these “simple mappings between stimuli and reactions will not be enough to keep the organisms from encountering problems.”
