Early gamma oscillations [PDF]

Neuroscience, 2013
Gamma oscillations have long been considered to emerge late in development. However, recent studies have revealed that gamma oscillations are transiently expressed in the rat barrel cortex during the first postnatal week, a "critical" period of sensory-dependent barrel map formation.

Gamma Oscillations in the Hippocampus

Physiology, 2010
Gamma oscillations are thought to temporally link the activity of distributed cells. We discuss mechanisms of gamma oscillations in the hippocampus and review evidence supporting a functional role for such oscillations in several key hippocampal operations, including cell grouping, dynamic routing, and memory.

Proprioceptive evoked gamma oscillations

Brain Research, 2007
A proprioceptive stimulus consisting of a weight change of a handheld load has recently been shown to elicit an evoked potential. Previously, somatosensory gamma oscillations have only been evoked by electrical stimuli. We conjectured that a natural proprioceptive stimulus also would be able to evoke gamma oscillations.

Hippocampal gamma oscillations in rats

IEEE Engineering in Medicine and Biology Magazine, 2009
Previous studies suggested that gamma oscillations in the brain are associated with higher order cognitive functions, including selective visual attention, motor task planning, sensory perception, working memory, and dreaming rapid eye movement (REM) sleep. These oscillations are mainly observed in the cortical regions and also occur in neocortical and

Gamma oscillations in a minimal CA3 model

Neurocomputing, 2006
A minimal model of the CA3 region of the hippocampus produces gamma oscillations. These oscillations exist across a broad range of conditions. For instance, the oscillations exist in the presence or absence of external input. Additionally, quantal synaptic failures do not eliminate the gamma oscillations. More importantly, there is a sensitivity to the
