A brief introduction to the brain-mind problem leads on to a survey of the neuronal structure of the cerebral cortex. It is proposed that the basic receptive units are the bundles or clusters of apical dendrites of the pyramidal cells of laminae V and III-II as described by Fleischhauer and Peters and their associates. There are up to 100 apical dendrites in these receptive units, named dendrons. Each dendron would have an input of up to 100,000 spine synapses. There are about 40 million dendrons in the human cerebral cortex. A study of the influence of mental events on the brain leads to the hypothesis that all mental events, the whole of the World 2 of Popper, are composed of mental units, each carrying its own characteristic mental experience. It is further proposed that each mental unit, named psychon, is uniquely linked to a dendron. So the mind-brain problem reduces to the interaction between a dendron and its psychon for all the 40 million linked units. In my 1986 paper (Proc. R. Soc. Lond. B 227, 411-428) on the mind-brain problem, there was developed the concept that the operation of the synaptic microsites involved displacement of particles so small that they were within range of the uncertainty principle of Heisenberg. The psychon-dendron interaction provides a much improved basis for effective selection by a process analogous to a quantal probability field. In the fully developed hypothesis psychons act on dendrons in the whole world of conscious experiences and dendrons act on psychons in all perceptions and memories. It is shown how these interactions involve no violation of the conservation laws. There are great potentialities of these unitary concepts, for example as an explanation of the global nature of a visual experience from moment to moment. It would seem that there can be psychons not linked to dendrons, but only to other psychons, creating what we may call a psychon world.

大脑皮层中脑脑相互作用的统一假设。

对脑力问题的简要介绍将导致对大脑皮层神经元结构的调查。如Fleischhauer和Peters及其同伴所描述的，建议基本的受体单位是层状V和III-II的锥体细胞的顶端树突的束或簇。在这些接受单位中，有多达100个顶端树突，称为树突。每个树突最多可输入100,000个脊柱突触。人类大脑皮层中约有4000万树突。对心理事件对大脑影响的研究得出这样的假设：整个“波普世界2”中的所有心理事件都是由心理单位组成的，每个单位都有自己独特的心理经验。进一步建议，每个名为psychon的精神单元都与树突唯一链接。因此，对于所有4,000万个链接单元，脑部问题都简化为树突与其心理子之间的交互。在我于1986年发表的关于心脑问题的论文（Proc。R. Soc。Lond。B 227，411-428）中，提出了一个概念，即突触微位点的操作涉及很小的颗粒位移，以至于它们在范围内。海森堡的不确定性原理。Psychon-Dendron交互通过类似于量子概率场的过程为有效选择提供了大大改善的基础。在充分发展的假设中，心理子在意识体验的整个世界中作用于树突，而树突子在所有感知和记忆中作用于心理子。显示了这些相互作用如何不违反保护法则。这些单一概念的潜力很大，例如，作为对视觉体验全球性的解释。似乎可能存在不与树突相关的心理子，而仅与其他心理子有关，从而创造了我们可以称之为心理子世界的世界。
