| 9. | If the parasite can alter rat behavior , does it have any effect on humans ? dr . e . fuller torrey associate director for laboratory research at the stanley medical research institute noticed links between toxoplasma and schizophrenia in human beings , approximately three billion of whom are infected with t . gondii : toxoplasma infection is associated with damage to astrocytes , glial cells which surround and support neurons . schizophrenia is also associated with damage to astrocytes 虽然那是科幻故事,但就寄生虫到底能否改变人类行为这一说法,目前科学界还真掌握了不少论据:首先,世界上约有300万精神分裂症患者同时感染了弓浆虫病感染弓浆虫与大脑内星形胶质细胞受损有关星形胶质细胞是一种围绕和支持神经元的神经胶质细胞,而神经分裂症同样与星形胶质细胞受损有关本身具有高水平弓浆虫 |
