The amygdala has repeatedly been implicated in emotional reactions and in learning of new emotionally significant stimuli. The system forms an important part of motor learning as well as attention. This paper presents a neurologically inspired computational model of the amygdala and the orbitofrontal cortex that aims to partially reproduce the same characteristics as the biological system. This model has been tested in simulations, the results of which are presented.
The equation that describes the update of the weights to the O nodes should be as follows:
ΔWi = β(Si[E-Rew])
