INTRODUCTION Multiple memory systems theory holds that different brain regions support distinct types of learning. The extent to which a given memory system exerts control over behavior depends on the types of sensory stimuli present and the extent to which they can make predictions about the future (White and McDonald, 2002). Prior experience, emotion and hormones are some of the many factors that can also influence which memory system, and associated strategies, are employed to solve a given problem. Two systems that mediate distinct and complementary types of learning are the hippocampal and dorsal striatal memory systems. The hippocampus forms a rich set of associations between sensory stimuli of all modalities (often referred to as cognitive memory), enabling flexibility in goaldirected behavior (Schiller et al., 2015). For example, by forming associations between multiple different cues in an environment, the hippocampus enables rodents to navigate to a specific place in an environment (Morris et al., 1982; Eichenbaum et al., 1990). In contrast, the dorsal striatum supports stimulusresponse behaviors, where a subject learns to perform a specific response to a discrete cue (often referred to as habit memory)(Packard et al., 1989). Examples include learning to approach a specific cue, or make a specific body turn at a choice point, in order to receive a reward. While stimulusresponse learning is often referred to as dorsal striatumdependent, it is primarily a function of the dorsolateral striatum (Devan and White, 1999) (but see (Ferbinteanu, 2016). Many of the factors that regulate the relative use of these two memory systems have been identified using “dual solution” navigational tasks in rodents, which can be solved through either spatial or response strategies. When these strategies are congruent, dysfunction in either the hippocampus or dorsal striatum does not affect performance since the animal can rely on the other system to solve the task. However, the interactive nature of these two memory systems can be revealed when, after a period of training, task modifications cause spatial and response strategies to produce conflicting outcomes. In this scenario, the subject must choose between strategies. Compromising one J This article is protected by copyright. All rights reserved.
