| Description
| - Cílem studie bylo prozkoumat korové aktivační změny během nebolestivého chladového a teplého podnětu aplikovaného na pravý palcový val. Bylo použito korové mapování 10 Hz oscilací EEG metodou %22low-resolution tomography%22. Zjistili jsme, že první aktivace při působení chladu se dostavuje v kontralaterální zadní insule a premotorické kůře. Při působení tepla se ukázala první aktivace pouze v kontralaterální premotorické korové oblasti. Zadní insula, premotorická oblast a přední insula ukázaly významné korelace mezi změnou teploty a amplitudou 10 Hz oscilací. Výsledky ukazují, že dynamická tepelná stimulace aktivuje jak zadní insulu, tak mediální a laterální premotorické oblasti. (cs)
- Primary cold and warm afferent fibers show a robust overshoot in their firing during periods of temperature change, which subsides during tonic thermal stimulation. Our objective was to analyze cortical activation, on a scale of hundreds of milliseconds, occurring during the process of dynamic cooling and warming, based on an evaluation of the amplitude changes seen in 10 Hz electroencephalographic oscillations. Eleven right-handed subjects were exposed to innocuous cold ramp stimuli (from 32 degrees C to 22 degrees C, 10 degrees C/s) and warm ramp stimuli (32 degrees C to 42 degrees C, 10 degrees C/s) on the thenar region of their right palm, using a contact thermode. EEG was recorded from 111 scalp sites, and the 10 Hz current source densities were modeled using low-resolution electromagnetic tomography. During cooling, the earliest amplitude decreases of 10 Hz oscillations were seen in the contralateral posterior insula and secondary somatosensory cortex (SII), and the premotor cortex (PMC).
