event - related gamma band activity in the lateral
44 Although the thalamus is an important module in ‘pain networks’, there are few studies of 45 the effect of experimental pain upon thalamic oscillations. We have now examined the 46 hypothesis that during a series of painful cutaneous laser stimuli thalamic signals will show 47 stimulus-related gamma band spectral activity, which is modulated by attention to versus 48 distraction from the pai...
متن کاملEnhanced EEG gamma-band activity reflects multisensory semantic matching in visual-to-auditory object priming
An important step in perceptual processing is the integration of information from different sensory modalities into a coherent percept. It has been suggested that such crossmodal binding might be achieved by transient synchronization of neurons from different modalities in the gamma-frequency range (>30 Hz). Here we employed a crossmodal priming paradigm, modulating the semantic congruency betw...
متن کاملPainful cutaneous laser stimuli induce event-related gamma-band activity in the lateral thalamus of humans.
Although the thalamus is an important module in "pain networks," there are few studies of the effect of experimental pain upon thalamic oscillations. We have now examined the hypothesis that, during a series of painful cutaneous laser stimuli, thalamic signals will show stimulus-related gamma-band spectral activity, which is modulated by attention to vs. distraction from the painful stimulus.

متن کاملInduced Gamma-band Activity Elicited by Visual Representation of Unattended Objects
Object recognition is achieved through neural mechanisms reliant on the activity of distributed neural assemblies that are thought to be coordinated by synchronous firing in the gamma-band range (>20 Hz). An outstanding question focuses on the extent to which the role of gamma oscillations in object recognition is dependent on attention. Attentional mechanisms determine the allocation of percep...
متن کاملA cross-laboratory study of event-related gamma activity in a standard object recognition paradigm.
This study proposes a standard paradigm for the investigation of visual information processing by means of gamma activity and presents a novel set of stimuli with a broad range of complex, coloured familiar real world and unfamiliar nonsense objects which are well matched with respect to physical stimulus properties. In order to demonstrate that the paradigm and stimulus set yield reliable resu...
