Discusses techniques for studying large-scale brain activity, insights from computational modeling, and cognitive processes that could lead to a better understanding of cognition. Describes interactions between psychology and physiology in perception, structural levels of organization in the nervous system, techniques and research strategies. (RT)

Reviews a study which sought to obtain a quantitative metabolic map of the neurons mediating a specific memory. Research results support notions of cooperative processes in which nonrandom behavior of high ensembles of neural elements mediates the integration and processing of information and the retrieval of memory. (ML)

This article reviews the work on patients who have undergone partial or complete brain bisection and addresses the concept of modularity from three different perspectives: (1) structure-function correlations; (2) modular components of cognitive processes; and (3) integration of modular processes. Several brain pictures and diagrams are presented.…

Discusses current learning theories, indicating that though many psychologists and ethologists now agree on using a mechanistic approach, some linguists doubt its adequacy. Implications of research on the mollusk "Aplasia" to understand the learning process are included. (JN)

Focuses on the brain processes and brain systems involved in learning and memory from a neuropsychological perspective of analysis. Reports findings related to the locus of memory storage, types of memory and knowledge, and memory consolidation. Models of animal memory are also examined. An extensive reference list is included. (ML)

Assesses the sensory and cognitive functions in a right-handed male before and after partial and complete callosal commissurotomy. (Author/SK)

Describes recent research findings in the area of neurobiology and its relationship to learning and memory. The article provides definitions of associative and nonassociative learning, identifies essential memory trace circuits of the mammalian brain, and discusses some neural mechanisms of learning. (TW)
