Modulation of gamma oscillations recorded from the human motor cortex and basal ganglia appears to play a key role in movement execution. However, there are still major questions to be answered about the specific role of cortical gamma activity in bo

International audience; Gamma rhythm (20–100Hz) plays a key role in numerous cognitive tasks: working memory, sensory processing and in routing of information across neural circuits. Incomparison with lower frequency oscillations in the brain, gamm

Dual roles for spike signaling in cortical neural populations

Autor: Dana eBallard, Janneke eJehee

Publikováno v: Frontiers in Computational Neuroscience, Vol 5 (2011)

A prominent feature of signaling in cortical neurons is that of randomness in the action potential. The output of a typical pyramidal cell can be well fit with a Poisson model, and variations in the Poisson rate repeatedly have been shown to be corre

During visual stimulation, neurons in visual cortex often exhibit rhythmic and synchronous firing in the gamma-frequency (30-90 Hz) band. Whether this phenomenon plays a functional role during visual processing is not fully clear and remains heavily

Local and systemic modulation of hippocampal oscillations and synaptic plasticity

Autor: Wójtowicz, Anna Maria

Hippocampal network oscillations of distinct frequency bands like gamma- oscillations and sharp wave-ripple complexes (SPW-Rs) are likely involved in various cognitive functions such as the storage of information and memory consolidation in vivo. Mem
