The adult brain has been thought traditionally as a structure with a very limited regenerative capacity. It is now evident that neurogenesis in adult mammalian brain is a prevailing phenomenon. Neural stem cells with the ability to self-renew, differentiate into neurons, astrocytes and oligodendrocytes reside in some regions of the adult brain. Adult neurogenesis can be stimulated by many physiological factors including pregnancy. More strikingly, newborn neurons in hippocampus integrally function with local neurons, thus neural stem cells might play important roles in memory and learning function. It seems that neural stem cells could transdifferentiate into other tissues, such as blood cells and muscles. Although there are some impediments in this field, some attempts have been made to employ adult neural stem cells in the cell replacement therapy for traumatic and ischemic brain injuries.

摘 要  注重培养学生的乐感,提高音乐素养;根据儿童的心理变化指导其合理的练琴方法等是一恒久的研究课题。在钢琴教学中儿童阶段是特殊的年龄层,他们在智力与生理与心理上都未成熟,但存在着较大的发展潜力与空间。为了更好地提高儿童的钢琴学习成效,教师应从长远的角度去训练学生。本文从放松、读谱、敏锐的听觉以及对儿童乐感培养的方法等方面进行了简单的表述。  【关键词】儿童;音乐感;前瞻性;钢琴教学;练习习惯;
