Systems and cognitive neuroscience depend on carefully designed and precisely implemented behavioral tasks to elicit the neural phenomena of interest. To facilitate this process, we have developed a software system that allows for the straightforward coding and temporally-reliable execution of these tasks in Matlab. We find that, in most cases, millisecond accuracy is attainable, and those instances in which it is not are usually related to predictable, programmed events. In this report, we describe the design of our system, benchmark its performance in a real-world setting, and describe some key features.
系统与认知神经科学依赖精心设计且精确实施的行为任务来引发感兴趣的神经现象。为推动这一过程，我们开发了一个软件系统，该系统能在Matlab中对这些任务进行直接编码并实现时间上可靠的执行。我们发现，在大多数情况下，可实现毫秒级精度，而那些无法实现的情况通常与可预测的、已编程的事件有关。在本报告中，我们描述了我们系统的设计，在实际环境中对其性能进行基准测试，并描述了一些关键特性。
