Behavior is a complex product of interactions between sensory influx arising from the environment and the neural state of the organism. Therefore, identical sensory input can elicit different behavioral responses. Research in recent years has demonstrated that perception is modulated when an organism is engaged in active behavior – suggesting that neural activity in motor pathways is one factor governing the neural state of networks engaged in sensory processing. In the current manuscript, we focus on the auditory modality and propose a mechanism by which activity in motor cortex changes the neural state in auditory cortex through global inhibition. In turn, such global inhibition reduces auditory net population activity, sharpens auditory frequency tuning curves, shifts the auditory oscillatory state and increases the signal-to-noise ratio of auditory evoked neural activity. These changes can result in either attenuated or enhanced behavioral responses depending on the environmental context. We base our model on animal and human literature and suggest that these motor-induced shifts in sensory states may explain reported phenomena and apparent discrepancies in the literature of motor-sensory interactions, such as sensory attenuation or sensory enhancement.

运动输出,神经状态和听觉感知

行为是环境和机体神经状态引起的感觉流入之间相互作用的复杂产物。因此,相同的感觉输入可以引起不同的行为反应。近年来的研究表明,当生物体进行活跃行为时,知觉就会受到调节-这表明运动通路中的神经活动是控制参与感觉过程的网络的神经状态的一个因素。在当前的手稿中,我们着重于听觉形态,并提出了一种机制,通过该机制运动皮层中的活动通过全局抑制来改变听觉皮层中的神经状态。反过来,这种全局抑制会减少听觉净人口活动,锐化听觉频率调整曲线,改变听觉振荡状态并增加听觉诱发的神经活动的信噪比。这些变化可能导致减弱或增强的行为响应,具体取决于环境。我们将模型建立在动物和人类文献的基础上,并建议这些由运动引起的感觉状态转变可能可以解释在运动与感觉相互作用的文献中报道的现象和明显差异,例如感觉减弱或感觉增强。
