Thalamic and cortical spindles during early ontogenesis in kittens.
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.
