Fig. 3. Cortical neurotrophins accelerate development of LGN neurons. Medians of
contralateral (white circles) and ipsilateral (black circles) LGN were
compared at P20 (NT-4/5, n=2), and P28 (NT-4/5 and NGF, total
n=7) and at P45 (NT-4/5, combined n=4 plus n=2
untreated P45 animals). NT-4/5 and NGF data were pooled, because both factors
elicited the same highly significant size shifts (compare
Fig. 1C with 1D). Contralateral
somata progressively reach the adult size whereas ipsilateral somata reach
adult sizes prematurely because of NT-4/5 and NGF infusions.
