Abstract

P300, somatosensory evoked potential (SEP) and brainstem auditory evoked potential (BAEP) are widely used neurophysiological methods for objectively evaluating cognitive, somatosensory and brainstem auditory functions. We studied the P300, SEP and BAEP in 17 patients with chronic respiratory insufficiency (PaO2:58.2 +/- 7.0 mmHg; mean +/- SD) and 15 age-matched healthy subjects (PaO2: 84.4 +/- 11.3 mmHg). The latency and amplitude of P300, the N9 latency, N9-N13 and N13-N20 interpeak latencies (IPL) in SEP, wave I latency and I-V IPL in BAEP were compared between the patients and controls. The P300 latency, N9-N13 and N13-N20 IPLs in SEP in the patients were significantly prolonged compared to the controls. In contrast, the amplitude of P300, N9 latency in SEP, wave I latency and I-V IPL in BAEP were not significantly different between the patients and controls. These results suggest that chronic respiratory insufficiency influences the cognitive and somatosensory functions, and indicate that there is a selective vulnerability of evoked potentials to this condition.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.

Barrel cortex

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.
