Before revision: Standard artificial neural networks (ANNs), loosely based on the structure of columns in the cortex, model key cognitive aspects of brain function such as learning and classification, but do not model the affective (emotional) aspects of brain function. However these are a key feature of the brain (the associated `ascending systems' have been hard-wired into the brain by evolutionary processes) . These emotions are associated with memories when neuromodulators such as dopamine and noradrenaline affect  entire patterns of synaptically activated neurons.
After revision: In this paper we introduce a novel Salience Affected Artificial Neural Network (SANN) that models the way neuromodulators such as dopamine and noradrenaline affect entire patterns of synaptically activated neurons.
