持续的电流等级通过反馈电路形成,该电路还可调节动物间不同的阻抗。
动物阻抗能够被预测试和显示,并且在阻抗太高而不能发出理想的电流信号时,会自动警报提示。
角膜和耳使用标准的电极,也可根据实验人员的需要定制电极。有逆变器、双相单元、双极型逆变器可选。
特殊的输出电路可以使用任何类型的电极。
电休克仪专用于神经化学和神经药理学研究。
恒定的电流能够确保测量结果有良好的重复性和由药物对大脑皮层或大脑皮下层区域引起电休克进行精确测定。冲击参数是根据最相关的文献选择的,它的范围是最适合大鼠和小数的。

The ECT Apparatus is specially designed for neurochemical and neuropharmacological research. It is particularly useful for:
A constant current output is used which ensures reproducible results and accurate determination of the EC threshold while also pinpointing any variation in the threshold brought about by drugs having specific action on the cortex and subcortical regions.
The shock parameters have been selected after consulting the most recent literature, in order to determinate the range of requirements likely to be needed when operating with mice and rats.
6Hz model: The 6-Hz corneal stimulation model, which was introduced in early fifties, has been recently rediscovered to test alternative approaches for drug-resistant seizures. Accordingly the ketogenic diet, which is known to be a valid treatment for refractory seizures, was found to be effective in counteracting seizures induced by the 6-Hz corneal stimulation. When compared with other models based on electrical stimulation, the 6-Hz paradigm is characterized by the induction of minimally convulsive or non-convulsive seizures with automatized behaviors, defined as “psychomotor seizures”. Ugo Basile ECT Unit performs the 6Hz model conveniently.
