In sync: gamma oscillations and emotional memory [PDF]
Emotional experiences leave vivid memories that can last a lifetime. The emotional facilitation of memory has been attributed to the engagement of diffusely projecting neuromodulatory systems that enhance the consolidation of synaptic plasticity in regions activated by the experience.

Gamma Oscillations and Emotional Memory [PDF]
Abstract Increased visual gamma band activity is known to relate to memory and encoding in cognitive tasks and has been shown to be present during arousing compared to neutral stimulus processing. Here, we set out to investigate whether gamma activity is stronger for later remembered compared to later forgotten emotional pictures ...

Distinct gamma-band components reflect the short-term memory maintenance of different sound lateralization angles [PDF]
Oscillatory activity in human electro- or magnetoencephalogram has been related to cortical stimulus representations and their modulation by cognitive processes.

Finely-tuned gamma oscillations: Spectral characteristics and links to dyskinesia [PDF]
Gamma oscillations comprise a loosely defined, heterogeneous group of functionally different activities between 30 and 100 Hz in the cortical and subcortical local field potential (LFP) of the motor network. Two distinct patterns seem to emerge which are

Performance- and stimulus-dependent oscillations in monkey prefrontal cortex during short-term memory [PDF]
Short-term memory requires the coordination of sub-processes like encoding, retention, retrieval and comparison of stored material to subsequent input. Neuronal oscillations have an inherent time structure, can effectively coordinate synaptic integration

Cortical gamma oscillations occur alongside perceptual processes, and in proportion to perceptual salience. They have a number of properties that make them ideal candidates to explain perception, including incorporating synchronised discharges of neural ...

Gamma oscillations in cognitive disorders
Gamma oscillations (∼25-100 Hz) are believed to play a role in cognition. Accordingly, aberrant gamma oscillations have been observed in several cognitive disorders, including Alzheimer's disease and Fragile X syndrome. Here, we review how recent results showing abnormal gamma rhythms in Alzheimer's disease and Fragile X syndrome help reveal links ...

Cooperation and competition of gamma oscillation mechanisms [PDF]
Oscillations of neuronal activity in different frequency ranges are thought to reflect important aspects of cortical network dynamics. Here we investigate how various mechanisms that contribute to oscillations in neuronal networks may interact.

Neural components underlying subjective preferential decision making [PDF]
The objectives of the current study were twofold: (i) to investigate the neural precursors of the formation of a subjective preference of facial stimuli, and (ii) to characterize the spatiotemporal brain activity patterns distinguishing between preferred

Autaptic connections and synaptic depression constrain and promote gamma oscillations.
Computational models of gamma oscillations have helped increase our understanding of the mechanisms that shape these 40-80 Hz cortical rhythms. Evidence suggests that interneurons known as basket cells are responsible for the generation of gamma ...
