Description
Scalp-applied recording electrodes were used to monitor changes in basal EEG patterns in chickens during posthatch development. Frequency spectra produced by Fast Fourier Transform show a biphasic morphology in all chickens with one peak at about 6 Hz and another at 26 Hz. Changes in the lower frequency band show progressive development and provide a possible index of brain development. Both amplitude and dominant frequency of the spectra decrease between Weeks 3 and 8 posthatch, reaching adult levels between Weeks 5 and 7. These results suggest that modifications of basal EEG reflect the widespread functional changes in neuronal circuits occurring in chicken during the synapse maturation period between 3 and 8 weeks' posthatch.
