An Improved Abstract For The NeuroReport Manuscript

I looked closely at the Abstract that I posted yesterday, and realized that it was unclear at the end. So I worked on it today and re-did the last several sentences. So here it is again, the Abstract for our submission to the journal NeuroReport:

The sexually dimorphic fish Lythrurus fasciolaris (scarlet shiner) is a seasonal breeder. Morphological and molecular changes in breeding season were examined in three regions of the brain: the cerebellum, optic tectum and telencephalon. Male brain mass relative to body mass is significantly more variable than female. Males have larger average volumes than females in these brain regions relative to total brain mass. The quantity and location of NMDA receptors in relation to sex and reproductive status was examined. Early in the breeding season dominant males have 3.5-fold higher expression of NMDARs than non-dominant males in all brain regions. At the peak of breeding season females exhibit higher levels of NMDAR expression than males. NMDARs undergo both temporal and sex-specific regulation.
