引言 關於刺激大腦皮層上4區與4S區的工作,在英美方面已有不少人做過。他們有的是以猴,有的是以狗或貓為材料,通過急性或慢性手術實驗的。我們是以急性手術為主,用乏極化電極分别刺激貓大腦皮層4S區與4區,並同時記錄伸屈肌的收縮,企圖用刺激皮層的方法以求得對4S區和4區的機能及其相互關係的瞭解。 INTRODUCTION The work on stimulating the 4 and 4S regions of the cerebral cortex has been done by many people in the Anglo-American context. Some of them are monkeys, some of them are dogs or cats, tested by acute or chronic surgery. We are mainly based on acute surgery, respectively, with a non-polarized electrode to stimulate the cat cerebral cortex 4S and 4, respectively, while recording the flexor flexor contraction in an attempt to stimulate the cortex in order to obtain the 4S and 4 zone function And their mutual understanding.
