Assembled by the prominent psychologists Daniel Schacter and Endel Tulving, the contributions in "Memory Systems 1994" focus on the nature and number of memory systems in humans and animals. Together they present ideas from cognitive psychology, neuropsychology, and neuroscience in a review of intriguing experimental outcomes at the cutting edge of this domain, grappling, often passionately, with the behavioral and neuroanatomical composition of memory systems and subsystems. Chapters are revised versions of contributions that appeared in a special issue of the Journal of Cognitive Neuroscience. This book includes an integrated discussion of and cross-commentary on the earlier contributions. "A Bradford Book"

Current theories about human memory have been shaped by clinical observations and animal experiments. This doctrine holds that the medial temporal lobe subserves one memory system for explicit or declarative memories, while the basal ganglia subserves a separate memory system for implicit or procedural memories, including habits. Cortical areas outside the medial temporal lobe are said to function in perception, motor control, attention, or other aspects of executive function, but not in memory. 'The Evolution of Memory Systems' advances dramatically different ideas on all counts. It proposes that several memory systems arose during evolution and that they did so for the same general reason: to transcend problems and exploit opportunities encountered by specific ancestors at particular times and places in the distant past. Instead of classifying cortical areas in terms of mutually exclusive perception, executive, or memory functions, the authors show that all cortical areas contribute to memory and that they do so in their own ways-using specialized neural representations. The book also presents a proposal on the evolution of explicit memory. According to this idea, explicit (declarative) memory depends on interactions between a phylogenetically ancient navigation system and a representational system that evolved in humans to represent one's self and others. As a result, people embed representations of themselves into the events they experience and the facts they learn, which leads to the perception of participating in events and knowing facts. 'The Evolution of Memory Systems' is an important new work for students and researchers in neuroscience, psychology, and biology.

We are pleased to present this collection of papers from the Second Workshop on Intelligent Memory Systems. Increasing die densities and inter chip communication costs continue to fuel interest in intelligent memory systems. Since the First Workshop on Mixing Logic and DRAM in 1997, technologies and systems for computation in memory have developed quickly. The focus of this workshop was to bring together researchers from academia and industry to discuss recent progress and future goals. The program committee selected 8 papers and 6 poster session abstracts from 29 submissions for inclusion in the workshop. Four to five members of the program committee reviewed each submission and their reviews were used to numerically rank them and guide the selection process. We believe that the resulting program is of the highest quality and interest possible. The selected papers cover a wide range of research topics such as circuit technology, processor and memory system architecture, compilers, operating systems, and applications. They also present a mix of mature projects, work in progress, and new research ideas. The workshop also included two invited talks. Dr. Subramanian Iyer (IBM Microelectronics) provided an overview of embedded memory technology and its potential. Dr. Mark Snir (IBM Research) presented the Blue Gene, an aggressive supercomputer system based on intelligent memory technology.

The State of Memory Technology Over the past decade there has been rapid growth in the speed of micropro cessors. CPU speeds are approximately doubling every eighteen months, while main memory speed doubles about every ten years. The International Tech nology Roadmap for Semiconductors (ITRS) study suggests that memory will remain on its current growth path. The ITRS short-and long-term targets indicate continued scaling improvements at about the current rate by 2016. This translates to bit densities increasing at two times every two years until the introduction of 8 gigabit dynamic random access memory (DRAM) chips, after which densities will increase four times every five years. A similar growth pattern is forecast for other high-density chip areas and high-performance logic (e.g., microprocessors and application specific inte grated circuits (ASICs)). In the future, molecular devices, 64 gigabit DRAMs and 28 GHz clock signals are targeted. Although densities continue to grow, we still do not see significant advances that will improve memory speed. These trends have created a problem that has been labeled the Memory Wall or Memory Gap.

Drug addiction may be viewed as a form of learning during which strong associations linking actions to drug-seeking are expressed as persistent stimulus–response habits, thereby maintaining a vulnerability to relapse. Disrupting cue–drug memory could be an efficient strategy to reduce the strength of cues in motivating drug-taking behavior. Upon reactivation, these memories undergo a reconsolidation process that can be blocked pharmacologically, providing an opportunity to prevent the powerful control of drug cues on behavior. This conceptually elegant approach still calls for more experimental data. However, an increasing body of evidence suggests that drug taking not only accelerates habit forming, but has long-lasting effects on interactions between memory systems eventually leading to a functional imbalance. The dorsal part of the striatum plays a critical role in habit/procedural learning, whereas the hippocampal memory system encodes relationships between events and their later flexible use. Both humans and rodents studies support the view that the hippocampus and the dorsal striatum interact in either a cooperative or competitive manner during learning, the prefrontal cortex being involved in the selection of an appropriate learning strategy. Chronic drug consumption biases normal interactions between these memory systems. For instance, drug-experienced rodents tend to use preferentially striatum-dependent learning strategies in navigational tasks. These persistent effects seem to occur at cellular, neurophysiological and behavioral levels to promote specific, striatal-dependent forms of learning, to the detriment of spatial/declarative, hippocampal-dependent and more flexible types of memory. Whether cue sensitive and response learners, in contrast to spatial learners, could be prone to drug addiction is an intriguing hypothesis which clearly deserves to be further explored. A loss of flexibility may be uncovered also by imposing changing rules on the subject, such as requiring an attentional shift between different perceptual features of a complex stimulus, as in the attentional set shifting task which was recently adapted to rodents. Working memory is at risk during transition phases, although it remains to be determined whether withdrawal-induced alterations are observed also during protracted abstinence. Drug-induced cognitive biases thus lead to cognitive rigidity which could play a critical, yet overlooked role in different phases of addiction (acquisition, extinction/withdrawal and relapse). They are also likely to preclude the clinical efficiency of treatments. Therefore, the aim of this research topic is to provide an overview of the current work investigating the long-term impact of drug use on learning and memory processes, how multiple memory systems modulate drug-seeking behavior, as well as how drug-induced cognitive biases could contribute to the persistence of addictive behaviors.

The purpose of this book is to describe the memory system of the brain, taking into account all the levels of neural organization: molecule, cell, small network, and anatomical circuit. This synthetic approach is necessary for determining the real mechanisms among the potential ones, that is the neural bases of learning and memory in intact organisms functioning under normal conditions. For this purpose, data from molecular, cellular and behavioral neurobiology, neuropsychology, animal and human psychology, and neural modellization are comprehensively reviewed by leading specialists and brought together in an original synthesis.
