CSF homovanillic acid levels showed a significant negative correlation with ventricle-brain ratios (VBRs) in a group of drug-free chronic schizophrenic male veterans, while CSF 5-hydroxyindoleacetic acid levels showed a similar, nearly significant trend. The response of plasma human growth hormone to 0.75 mg of apomorphine also demonstrated a significant negative correlation with VBR in this group, but other measures of central neurotransmitter activity were unrelated to ventricular size.
在一组未使用药物的慢性精神分裂症男性退伍军人中，脑脊液高香草酸水平与脑室-脑比率（VBRs）呈显著负相关，而脑脊液5-羟吲哚乙酸水平呈现出类似的、近乎显著的趋势。该组中，血浆人生长激素对0.75毫克阿扑吗啡的反应也与VBR呈显著负相关，但其他中枢神经递质活性指标与脑室大小无关。
