Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: An integrative theory relating cognitive aging de"cits observed at the behavioral level with age-related de"ciency in neuromodulation causing less distinctive cortical representations is tested in a series of neural network simulations. Age-related attenuation of catecholaminergic function is simulated by loring the mean gain of the processing unit, which subsequently reduces responsivity and raises intra-network activation variability. Age di!erences in learning rate, asymptotic performance, interference susceptibility, complexity cost, intra- and interindividual variability, and ability dedi!erentiation can all be modeled. Together, the simulations illustrate catecholamine’s role in regulating the "delity of neural information processing and subsequent e!ects leading to cognitive aging de"cits.
