Dark-rearing modifies serotonin and 5-hydroxyindoleacetic acid contents in specific regions of rabbit brain


, : Dark-rearing modifies serotonin and 5-hydroxyindoleacetic acid contents in specific regions of rabbit brain. Behavioural Brain Research 31(2): 115-120

The contents of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) in specific brain regions of rabbits dark-reared from birth until 3 months of age are higher than those of controls. After light exposure, 5-HT and 5-HIAA levels become similar to normal values. In adult rabbits kept in darkness for 3 months, 5-HT and 5-HIAA contents increase only in the superior colliculi. These results are discussed in relation to the early development of the vestibulo-ocular reflex.

Marbling, as defined by the amount of intramuscular fat, is an economically important trait in beef cattle. Intramuscular fat deposition is postulated to arise mainly from a series of adipogenic events in intramuscular adipocyte-lineage cells and...
