Recent studies aim to explain the duration and variability of behavioral reaction time in terms of neural processes. The time taken to make choices is occupied by at least two processes. Neurons in sensorimotor structures accumulate evidence that leads to alternative categorizations, while other neurons within these structures prepare and initiate overt responses. These distinct stages of stimulus encoding and response preparation support variable but flexible behavior.
最近的研究旨在从神经过程的角度解释行为反应时间的持续时间和变异性。做出选择所需的时间至少由两个过程占据。感觉运动结构中的神经元积累导致不同分类的证据，而这些结构中的其他神经元则准备并启动明显的反应。刺激编码和反应准备的这些不同阶段支持可变但灵活的行为。
