随着近代神经生化的迅速发展,毒物对神经系统的作用也深及到神经递质的研究领域。神经冲动的化学传递虽已确立了半个世纪,然而对神经递质研究得比较清楚还只是近一、二十年的事。在神经系统中存在许多具有生物活 With the rapid development of modern neurobiochemistry, the effects of poisons on the nervous system are also deeply involved in the field of neurotransmitter research. Although the chemical impulse of nerve impulses has been established for half a century, the study of neurotransmitter is relatively clear only for a decade or two. There are many living creatures in the nervous system
