摘要
Neuroscience has been extensively developed for more than seventy years;however,there still remains lack of breakthrough understanding in the neural information field.A quantum coherent state of ion channels is recently proposed in neural system as an information carrier,but its physical expression is still not fixed.Here,employing a simple K^(+)channel as a typical instance,we theoretically build a conceptual model for the quantum state of a neural ion channel and demonstrate the macroscopic coherence state of multiple ion channels.The underlying mechanism is revealed to the mid-infrared photons released by ion oscillation in one ion channel together with their resonant and coherent coupling with the oscillations in other channels.An additional environment field(e.g.,brain wave)may regulate the coherence,potentially relating to the human consciousness.Clearly,there exist the channels of other ions in a neural system,which also potentially form a macroscopic coherence state of themselves,with the mechanism identical to that of K^(+)channels.An environment field can be expected to further regulate the quantum states of various ionic channels,leading to a total macroscopic coherence state of these channels,which is like the conductor in a symphony to achieve the harmony in music.These findings are expected to provide a promising viewpoint for neuroscience,as well as to improve treatments of the diseases and health problems related to neural system.
神经科学广泛发展了70多年,然而对神经信息的本质仍缺乏突破性认识.最近报道,离子通道量子相干态可能是神经信息的一种新载体,但是其物理表达式仍然未确定.本文以K^(+)通道为例,从理论上建立了神经离子通道量子态的概念模型,展示了多离子通道的宏观相干态.该现象的物理机理是:(1)单个离子通道中离子振荡可以释放中红外光子,(2)多个离子通道通过该光子可以实现共振相干耦合.环境场(如脑电波)能够调节离子通道的相干性,与意识存在潜在的关联.神经系统中还存在其他离子通道,它们也可形成各自的宏观相干态,其机制与K^(+)通道相同.环境场可以进一步调控各种离子通道量子态,使它们产生整体相干.该现象类似于交响乐:不同的乐器(不同频率的离子通道及其相干态)由乐队指挥(环境场)统一调控,实现音乐和声(整体宏观相干态).这些研究发现有望为神经科学提供新观点,同时为神经系统相关疾病、健康问题的治疗提供新策略.
