We have made intracellular recordings from the dorsolateral septal nucleus (DLSN) in a rat brain slice. DLSN neurons fire short tetrodotoxin (TTX) sensitive action potentials followed by an after-hyperpolarization. The action potential is followed by either a Ca2+-dependent depolarization or a Ca2+-dependent after-hyperpolarization. Stimulation of medial septum results in antidromic invasion of DLSN neurons while stimulation of the fimbria/fornix results in orthodromic EPSPs or action potentials.
我们在大鼠脑片中对背外侧隔核(DLSN)进行了细胞内记录。DLSN神经元发放对河豚毒素(TTX)敏感的短动作电位,随后出现超极化后电位。动作电位之后要么是Ca2+依赖性去极化,要么是Ca2+依赖性超极化后电位。刺激内侧隔会导致DLSN神经元的逆向入侵,而刺激穹窿/穹窿则会导致顺向兴奋性突触后电位(EPSP)或动作电位。
