摘要：A detailed anatomy and histological structure of the brain and spinal cord, referring to the central nervous system and special sensory organ in the short mackerel, Rastrelliger brachysoma were firstly observed in this article. All specimens revealed that the brain nomenclature in R. brachysoma was anatomically consisted of telencephalon, mesencephalon, diencephalon, metencephalon and myelencephalon, which continued the spinal cord. According to histology and histochemistry, it revealed that the different structures and cell components were observed in each region. The telencephalon of the R. brachysoma was less developed with main consisting of olfactory lobes and cerebral hemisphere. The largest of the optic lobe in the mesencephalon was observed with six histologically distinct layers; stratum marginale, stratum opticum, stratum fibroetgricialem, stratum album central, stratum griseum central and stratum periventriculae, respectively. In regard to the diencephalon was situated beneath its mesencephalon. The epithalamus, thalamus and hypothalamus were principally seen in this region. The cerebellum in the metencephalon was composed of the corpus and the valvula cerebelli. The last region of the brain was myelencephalon, which had the medulla oblongata and vagal lobes before joining the spinal cord. Another observation, the eye structure with composing to inner, middle and external layers was investigated in this article.
