BACKGROUND
Transcranial magnetic stimulation (TMS) produces magnetic pulses by passing a strong electrical current through coils of wire. Repeated stimulation accumulates heat, which places practical constraints on experimental design. New method: We designed a condensation-free pre-chilled heat sink to extend the operational duration of transcranial magnetic stimulation coils.
RESULTS
The application of a pre-chilled heat sink reduced the rate of heating across all tests and extended the duration of stimulation before coil overheating, particularly in conditions where heat management was problematic. Comparison with existing method: Applying an external heat sink had the practical effect of extending the operational time of TMS coils by 5.8-19.3 minutes compared to standard operating procedures.
CONCLUSION
Applying an external heat sink increases the quantity of data that can be collected within a single experimental session.
背景
经颅磁刺激（TMS）通过在绕组中通过强电流产生磁脉冲。重复刺激会积累热量，这对实验设计构成了实际的限制。新方法：我们设计了一种无冷凝预冷的散热器，以延长经颅磁刺激线圈的工作时间。
结果
在所有测试中，使用预冷散热器降低了加热速率，并延长了在过热之前的刺激持续时间，特别是在散热有问题的情况下。与现有方法的比较：与标准操作程序相比，施加外部散热器实际上将 TMS 线圈的工作时间延长了 5.8-19.3 分钟。
结论
施加外部散热器可增加在单个实验过程中可收集的数据量。
