Non Reward Attractor Theory Of Depression. Abstract The nonreward attractor theory of depression describes this mood disorder as originating from a neuronal dysfunction that arises from increased vulnerability of a cortical network that detects failure to receive an expected reward. Increased activity in a lateral orbitofrontal cortex non-reward area provides a new attractor-related approach to understanding and treating depression. The roles of the orbitofrontal cortex via the habenula in non-reward and depression and in the responses of serotonin and dopamine neurons. A non-reward attractor theory of depression 1.
This triggers negative cognitive states which in turn have positive feedback top-down effects on the orbitofrontal cortex non-reward. A non-reward attractor theory of depression. A non-reward attractor theory of depression is proposed based on the operation of the lateral orbitofrontal cortex and supracallosal cingulate cortex. A non-reward attractor theory of depression is proposed based on the operation of the lateral orbitofrontal cortex and supracallosal cingulate cortex. A major unsolved problem in the theory of uctuations is that of noise-induced escape from a chaotic attractor 1Chaotic systems are widespread in nature and the study of their dynamics in the presence of uctuations is both of fundamen- tal interest and also of importance in relation to a range of applications eg. A computational theory of hippocampal function and tests of the theory.
The theory proposed is that in depression this lateral orbitofrontal cortex non-reward system is more easily triggered and maintains its attractor-related firing for longer.
