Imagine a situation where a patient has severe lim- itations in the capacity to express behavior overtly, while retaining perception, mem- ory, and cognition—the condition of cerebral palsy is a particularly striking case. Such a development is not practical at present, but it is not too soon to begin thinking about the design requirements for a device that could perform this function. In my view, we now have su‰cient data on the anatomy and physiology of the brain to encourage optimism that such a device could be developed. Furthermore, the findings allow us to set the goals and identify the challenges that have to be met as we look forward to this sort of development. These data fall into three main domains, each of which addresses a major question about the relevant brain circuitry and operation. First, what is the brain system that mediates conscious recollection and explicit expression of intentions? Specifically, what brain structures are involved in these functions, how are they connected, and what are the individual roles of each structure involved? Specifically, what kind of information is reflected in the firing patterns of individual neurons in each component of this functional system? Third, what do we know about the functional organization of the neural networks in these brain areas? That is, how do the neural elements act in concert beyond merely the sum of their independent information-coding properties? In particular, the hippocampal re- gion has been identified as central to conscious recollection, and the prefrontal cortex as central to the higher-order cognitive functions associated with the development of intentions and plans. This section considers the brain system that encompasses the hippocampal region and prefrontal cortex, as well as other cortical areas, specifically with regard to their interactions in memory functions. However, it has become clear that there are multiple memory systems in the brain, of which the hippocampal system is only one (Eichen- baum and Cohen, 2001). As Cohen and Squire (1980) first recognized, the hippocampal region plays a selec- tive role in declarative memory.
