The most important quest of cognitive neuroscience may be to unravel the mechanisms by which the
brain selects, links, consolidates and integrates new information into its neuronal network, while
preventing saturation to occur. During the last decade, neuroscientists working on the memory system
within several disciplines and in many labs over the world have observed an important involvement of
the specific types of brain oscillations that occur during sleep – the cortical slow oscillations; during
the resting state – the MRI default mode and other networks; and during task performance – the EEG
power and performance modulations. Understanding the role of these slow oscillations thus appear to
be essential for our fundamental understanding of the essentials of brain function. Never before has an
international meeting taken place that integrated these three fields of study and allowing for
crossfertilization.
Brain activity is characterized by oscillations; in spike frequency, field potentials or blood oxygen
level-dependent MRI signals. Environmental stimuli, reaching the brain through our senses, activate,
or inactivate, neuronal populations and modulate ongoing activity. In the absence of sensory input, as
is the case during rest or sleep, brain activity does not cease. Rather, its oscillations continue and
change with respect to their dominant frequencies and coupling topography. Studies ranging from the
molecular, physiological and behavioral to the cognitive level have in the past decade clearly indicated
that the study of these slow oscillations is essential for our understanding of plasticity, memory, brain
structure from synapse to default mode network, cognition, consciousness and ultimately for our
understanding of the mechanisms and functions of sleep and vigilance. At this 26th International
Summer School an international selection of the most renowned scientists advancing these fields will
present and discuss their work. The lectures will cover all levels of biological organization and are
targeted at Ph.D-students, postdoctoral fellows and senior researchers, both in basic and clinical
science, with an interest in plasticity, memory, sleep, vigilance, oscillations, default mode network
activity, cognition and consciousness.
