We recorded from spiking units in the first optic chiasm between lamina and medulla in the brain of the blowfly (Calliphora vicina). Both previously characterized neuron types, on-off units and sustaining units, were encountered. On-off units had a temporal frequency response with a lower cut-off frequency than blowfly photoreceptors. This low cut-off frequency is related to a fast temporal adaptation of the on-off units to trains of short light pulses. Temporal adaptation occurred independently for short on- and off-pulses. 2. On-off units only responded to stimuli of relatively large contrast. Contrasts of less than 10% gave little or no response.

我们在丽蝇（Calliphora vicina）大脑中位于视叶层和髓质之间的第一视交叉处的脉冲发放单元进行了记录。记录到了之前已被描述过的两种神经元类型，即开-关单元和持续单元。开-关单元具有一种时间频率响应，其截止频率低于丽蝇光感受器的截止频率。这种低截止频率与开-关单元对短光脉冲序列的快速时间适应性有关。开脉冲和关脉冲的时间适应是独立发生的。2. 开-关单元仅对对比度相对较大的刺激做出反应。对比度小于10%时几乎没有反应或完全不反应。
