High Gamma Power Is Phase-Locked to Theta Oscillations in Human Neocortex
We observed robust coupling between the high- and low-frequency bands of ongoing electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to 8 hertz) rhythmExpand

Voxel-based lesion–symptom mapping
For more than a century, lesion–symptom mapping studies have yielded valuable insights into the relationships between brain and behavior, but newer imaging techniques have surpassed lesion analysisExpand

Frontal Lobe Contributions to Theory of Mind
Theory of mind, the ability to make inferences about others' mental states, seems to be a modular cognitive capacity that underlies humans' ability to engage in complex social interaction. ItExpand

The functional role of cross-frequency coupling
Recent studies suggest that cross-frequency coupling (CFC) might play a functional role in neuronal computation, communication and learning. In particular, the strength of phase-amplitude CFC differsExpand

Prefrontal–cingulate interactions in action monitoring
We found that medial frontal cortex activity associated with action monitoring (detecting errors and behavioral conflict) depended on activity in the lateral prefrontal cortex. We recorded theExpand

Experiments were conducted to study the contribution of prefrontal cortex to the generation and modulation of two varieties of P300 activity. Control subjects generated typical parietal maximal P300Expand

  • 1 September 1996
THE ability to respond to unexpected stimuli (the 'orienting response') is a fundamental characteristic of mammalian behaviour1, but the brain mechanisms by which novelty is detected remain poorlyExpand

Categorical Speech Representation in Human Superior Temporal Gyrus
Speech perception requires the rapid and effortless extraction of meaningful phonetic information from a highly variable acoustic signal. A powerful example of this phenomenon is categorical speechExpand

Effects of extensive temporal lobe damage or mild hypoxia on recollection and familiarity
Memory for past events can be based on recollection or on assessments of familiarity. These two forms of human memory have been studied extensively by philosophers and psychologists, but theirExpand

Age-related top-down suppression deficit in the early stages of cortical visual memory processing
In this study, electroencephalography (EEG) was used to examine the relationship between two leading hypotheses of cognitive aging, the inhibitory deficit and the processing speed hypothesis. We showExpand
