Cortical neurons show irregular but structured spike trains. This has been interpreted as
evidence for'temporal coding', whereby stimuli are represented by precise spike-timing …

This paper is an attempt to understand how knowledge and events are represented and
processed in the brain. An important point is the question of what carries information in the …

Cortical circuits work through the generation of coordinated, large-scale activity patterns. In
sensory systems, the onset of a discrete stimulus usually evokes a temporally organized …

Hebb's idea of a cell assembly as the fundamental unit of neural information processing has
dominated neuroscience like no other theoretical concept within the past 60 years. A range …

A widely discussed hypothesis in neuroscience is that transiently active ensembles of
neurons, known as" cell assemblies," underlie numerous operations of the brain, from …

The ease with which highly developed brains can generate representations of a virtually
unlimited diversity of perceptual objects indicates that they have developed very efficient …

Identifying similar spike-train patterns is a key element in understanding neural coding and
computation. For single neurons, similar spike patterns evoked by stimuli are evidence of …

Although temporal coding is a frequent topic of neurophysiology research, trial-to-trial
variability in temporal codes is typically dismissed as noise and thought to play no role in …

Anatomical studies demonstrate that excitatory connections in cortex are not uniformly
distributed across a network but instead exhibit clustering into groups of highly connected …

Cognitive processes depend on synchronization and propagation of electrical activity within
and between neuronal assemblies. In vivo measurements show that the size of individual …
