Journal ArticleDOI
Propagation and stability of waves of electrical activity in the cerebral cortex
TL;DR: These equations incorporate nonlinearities, axonal and dendritic lags, excitatory and inhibitory neuronal populations, and the two-dimensional nature of the cortex, while rendering nonlinear features far more tractable than previous formulations, both analytically and numerically.
Journal ArticleDOI
Brain maturation in adolescence: concurrent changes in neuroanatomy and neurophysiology.
Thomas J. Whitford,Christopher J. Rennie,Christopher J. Rennie,Stuart M. Grieve,C. Richard Clark,Evian Gordon,Leanne M. Williams +6 more
TL;DR: It is suggested that the reduction in gray matter primarily reflects a reduction of neuropil, and that the corresponding elimination of active synapses is responsible for the observed reduction in EEG power.
Journal ArticleDOI
Arousal dissociates amygdala and hippocampal fear responses: evidence from simultaneous fMRI and skin conductance recording.
Leanne M. Williams,Mary L. Phillips,Michael Brammer,David Skerrett,Jim Lagopoulos,Christopher J. Rennie,Christopher J. Rennie,H. Bahramali,Gloria Olivieri,Anthony S. David,Anthony Peduto,Evian Gordon +11 more
TL;DR: The findings provide direct evidence for a dissociation between human amygdala and hippocampus networks in the visceral experience versus declarative fact processing of fear.
Journal ArticleDOI
Unified neurophysical model of EEG spectra and evoked potentials.
TL;DR: A broad range of ongoing and transient electrocortical activity can be understood within a common framework, which is parameterized by values that are directly related to physiological and anatomical quantities.
Journal ArticleDOI
Mechanisms of cortical electrical activity and emergence of gamma rhythm.
TL;DR: A continuum model of the electrical activity of the cerebral cortex is described which predicts the occurrence of a resonance in the gamma range near 40 Hz, and analytical expressions for the fixed points of the system and for its linear dynamics together explain the occurrence and modulation of the gamma-like resonance.
