Single-Sole Source Determination
The unique characteristics of the electrodes currently used in the present study; we must continue the study using these proprietary electrodes from Plexon Inc. Plexon Inc is the only commercial entity that supplies electrodes that meet all of the requirements. Only one source can furnish these items.
Background/Description of Requirement

The Laboratory of Neuropsychology investigates higher brain functions such as learning, memory and reward related decision making. Electodes are used for recording brain activity associated with motivated behaviors and to study pathways involved in decision making. Linear electrodes are ultrafine wires used to record signal from cells (neurons) in the brain. There are many characteristic requirements that must be met for such systems to work in a study. Once an specific electrode technology is selected, all other equipment, implants and electronics must work in unison with the chosen electrode technology. In this case, the technology has been chosen and the experiment has been started. However, we need two slightly different versions of the electrodes to solve the problem of clustering many (5) electrodes in a tightly packed space. This order is not a continuation of a prior order or contract. 

The project is aimed at advancing our understanding of reward-based learning. It combines large-scale neuronal recordings, challenging decision-making tasks by nonhuman primates and advanced computational modeling to better understand the role of dopamine in motivated behaviors. Animals have been trained on multiple decision-making tasks where they win juice rewards of different flavors. Electrodes are being used to record from multiple areas of the brain known to participate in these tasks. Behavior will be modeled using reinforcement learning algorithms, then the activity of simultaneously recorded neurons will be processed through an advanced computational pipeline to test hypotheses about the contribution of each brain area to decision making.
