title: Thalamic and cortical spindles during early ontogenesis in kittens.
abstract: On birth, focal thalamic recordings show sporadic sequences of spindle waves whereas EEG cortical recordings show no trace of spindles. Thalamic spindles are occasionally transferred to the cortex beginning with the 3rd-4th day. On the 8th-9th day, clear-out spindle sequences, with the same patterns as in the adult animal, appear simultaneously in the thalamus and cortex.
