[Centrifugal influence from the cortical taste area on neural activity of the parabrachial nucleus in rats].

To reveal the functional significance of fiber connections from the cortical taste area (CTA) to the parabrachial nucleus (PBN), a combined study with neuroanatomical and electrophysiological techniques were performed on male Wistar rats anesthetized with urethane. The results were as follows: 1. Tracing of WGA-HRP showed that the fibers connecting the CTA and PBN passed through the central tegmental field (CTF).

Relationship between changes in power spectra of electroencephalograms and arterial halothane concentration in infants.

A power spectral analysis of electroencephalograms (EEGs) was performed in 30 infants who underwent plastic surgery for cleft lip or cleft palate. The study was conducted to investigate whether there was a significant correlation between EEG changes and arterial halothane concentration in infants. The power spectral analysis of EEGs was performed by the fast Fourier transform (FFT).
