Infrared laser stimulators to study nociception

In 1975, Mor and Carmon introduced infrared laser stimulators as tools to explore nociception in humans. Allowing brief, synchronous, and selective activation of cutaneous Aδ- and C-fibre nociceptors, laser heat stimulators are now used extensively to study nociception in humans. Infrared laser...

Functional magnetic resonance imaging (fMRI)

Magnetic resonance imaging (MRI) uses radio waves and a strong magnetic field to provide images of internal organs and tissues. It does not use X-rays.  Functional MRI is a procedure that uses MRI to indirectly measure the neural activity occurring in the brain of humans (or other animals)....

Letswave 6 : Matlab toolbox for the analysis of EEG data

Letswave 6 is a Matlab EEG signal-processing toolbox developed to perform fast multi-subject analyses of electrophysiological data, in particular, stimulus-evoked EEG responses such as event-related brain potentials (ERPs),  event-related synchronization and desynchronisation (ERD and ERS), as...

EEG and Event-related brain potentials

Scalp electroencephalography (EEG) can be used to record event-related brain potentials (ERPs). ERPs appear as transient changes in the ongoing electrical brain activity, time-locked to the onset of the event. ERPs are hypothesized to result from sudden and synchronized increases of postsynaptic...
