Contact heat evoked potentials in normal subjects.

Laser-evoked potentials are widely used to investigate nociceptive pathways. The newly developed contact heat stimulator for evoking brain response has the advantages of obtaining reliable scalp potentials and absence of cutaneous lesions. This study aimed to identify the most appropriate stimulation site with consistent cortical responses, and to correlate several parameters of the contact hea...

Human event-related brain potentials to auditory periodic noise stimuli.

Periodic noise is perceived as different from ordinary non-repeating noise due to the involvement of echoic memory. Since this stimulus does not contain simple physical cues (such as onsets or spectral shape) that might obscure sensory memory interpretations, it is a valuable tool to study sensory memory functions. We demonstrated for the first time that the processing of periodic noise can be ...

Event related evoked potentials in hypertensive subjects.

Cognitive functions were assessed in hypertensive and sex and age matched healthy controls using auditory event related evoked potential 'odd ball' paradigm. The N2 and P3 latencies in the hypertensive subjects were significantly delayed as compared to controls. There was also correlation of blood pressure (BP) with N2 latency in hypertensive group. These findings suggest that cortical neurophy...

Steady state auditory evoked potentials in normal hearing subjects: evaluation of threshold and testing time.

BACKGROUND Steady state responses (SSRs), between 75 and 110 Hz, evoked by auditory amplitude modulated single or multiple tone stimuli, may be used to estimate objective hearing threshold. METHODS The aim of this study was to compare SSRs and click-evoked auditory brainstem responses (ABRs) in both ears of 20 adults (10 males and 10 females, aged between 24 and 36 years) with normal hearing ...

Long-latency auditory evoked potentials with verbal and nonverbal stimuli.

INTRODUCTION Long-latency auditory evoked potentials represent the cortical activity related to attention, memory, and auditory discrimination skills. Acoustic signal processing occurs differently between verbal and nonverbal stimuli, influencing the latency and amplitude patterns. OBJECTIVE To describe the latencies of the cortical potentials P1, N1, P2, N2, and P3, as well as P3 amplitude, ...
