Computational Models of Neuromodulation
Neuromodulatory systems serve a special meta-processing role in the brain. Due to their anatomical privileges of having massively extensive arborization patterns throughout the central and peripheral nervous systems and to their physiological capacity of finely controlling how other neurons communicate with each other and plasticize, they are ideally positioned to regulate the way information is acquired, processed, utilized, and stored in the brain. As such, neuromodulation has been a fertile ground for computational models for neural information processing, which have strived to explain not only how the major neuromodulators coordinate to enable normal sensory, motor, and cognitive functions but also how dysfunctions arise in psychiatric and neurological conditions when these neuromodulatory systems are impaired.
Although much still remains unknown or opaque about neuromodulatory functions, a computationally sophisticated and coherent picture is...
