Jf. Mccollum et al., GRANULE AND MITRAL CELL DENSITIES ARE UNCHANGED FOLLOWING EARLY OLFACTORY PREFERENCE TRAINING, Developmental brain research, 99(1), 1997, pp. 118-120
Early olfactory preference training causes both an increased number of
juxtaglomerular cells and an increased number of such cells expressin
g Fos protein. In contrast, there are fewer cells expressing Fos prote
in in the granule cell layer after training. Here, we report no change
in the number or size of granule and mitral cells as a consequence of
these early olfactory experiences.
