Gamma Rhythms in the Brain
Brain rhythms are activity fluctuations shared in populations of neurons. They are evident in extracellular electric fields and detectable through recordings performed within the brain or on the scalp. The gamma rhythm, a relatively high frequency (30– 80 Hz) component of these fluctuations, has received a great deal of attention. Gamma is modulated by sensory input and internal processes such ...
متن کاملGamma rhythms and beta rhythms have different synchronization properties.
Experimental and modeling efforts suggest that rhythms in the CA1 region of the hippocampus that are in the beta range (12-29 Hz) have a different dynamical structure than that of gamma (30-70 Hz). We use a simplified model to show that the different rhythms employ different dynamical mechanisms to synchronize, based on different ionic currents. The beta frequency is able to synchronize over lo...
متن کاملThe Psychophysics of Brain Rhythms
It is becoming increasingly apparent that brain oscillations in various frequency bands play important roles in perceptual and attentional processes. Understandably, most of the associated experimental evidence comes from human or animal electrophysiological studies, allowing direct access to the oscillatory activities. However, such periodicities in perception and attention should, in theory, ...
متن کاملBrain Rhythms: Enhancing Memories
A new study shows that different processes are responsible for maintaining relevant and suppressing irrelevant information. By promoting the suppression of irrelevant information, memories may be enhanced. Everyday we are bombarded with information from the media, colleagues, spouses and friends. Some of this information is relevant and important, but other information is irrelevant and should ...
