Attentional selection involves brain processes that select and control the flow of information into the mechanisms that underlie perception and consciousness. One theory proposes that the neural activity that represents the stimuli or events to be attended to is selected through modification of its synchrony. Recent experimental evidence supports this theory, by showing that changes in attentional focus increase the synchrony of neural firing in some neuron pairs and decrease it in others.
注意力选择涉及大脑过程，这些过程选择并控制信息流入构成感知和意识基础的机制。一种理论提出，通过改变其同步性来选择代表要关注的刺激或事件的神经活动。最近的实验证据支持了这一理论，通过表明注意力焦点的变化会增加一些神经元对中神经放电的同步性，而在其他神经元对中则会降低同步性。
