Abstract
Secondary neurons of the olfactory bulb can be excited monosynaptically after activation of neighboring secondary neurons by antidromic and orthodromic volleys. Recurrent collaterals of secondary neurons are proposed to synapse with other secondary neurons, thus forming a direct recurrent excitatory pathway. Such a positive feedback system could strengthen the original input signal.
摘要
嗅球的次级神经元在相邻次级神经元通过逆向和顺向冲动激活后可被单突触兴奋。次级神经元的回返侧支被认为与其他次级神经元形成突触，从而形成一条直接的回返性兴奋通路。这样一个正反馈系统可以增强原始输入信号。
