Athletic amenorrhea: energy deficit or psychogenic challenge?

abstract：:Alterations in brain distribution of 11C-MAP, 14C-MAP, and 123I-IMP in MAP- and cocaine-sensitized animals were examined to investigate the mechanism involved in increased dopaminergic transmission and behavioral sensitization. First, a significant increase in 11C-MAP radioactivity in the striatum and hypothalamus was...
