Dementia is prevalent in the aging population. Several studies have suggested a possible link between, limbic system anomalies and reward circuitry impairment in several forms of dementia. There are several difficulties in performing behavioral tasks with some patients due to the presence of the test administrator. Human interactions may alter patients' behavior. Thus, we have built and designed an Automated Memory Evaluation System (AMES) that measures the ability to remember geometric shapes of different colors and rewards positive patient responses as well as records response timings. The system is connected to a laptop to study the gustatory reward circuitry. Various computer neuropsychological tests, games, can be programmed to control the AMES to dispense foods (such as candies, chocolates, jellybeans) in variable amounts and various delayed timing. The AMES will allow us to probe into gustatory reward circuitry in the aging population without human interaction.
