  1. In fact, from the point of view of science, the brain is nothing more than a mechanism based on the laws of chemistry and biology.

    Modern science is not able to record the presence of consciousness (soul) and somehow measure it. That is, what is called the soul is currently undetectable. But that doesn't mean it doesn't exist.

    To answer your question, neuroscience considers only the biological properties of the brain and does not study its connection with our consciousness, since it is literally unable to detect consciousness in our skull.

    However, the existence of consciousness (the “external observer” as you call it) is obvious. It's just that at the moment, science is unable to detect it.

    There will probably be a breakthrough in this area in the coming centuries. And then we will be able to explore the mechanisms of interaction of our cell with the body.

  2. There is only the brain in our skull. No color, no sound, no taste, no smell, no tactile sensations are there and never were, if you think about it that way, then there are no thoughts there. If we open the skull, we will see the brain covered with meninges, if we look deeper and more closely, we will see a lot of nerve strands, clusters of nerve cells, deeper we will see billions of neurons communicating with each other by axons and dendrites. And along the axons and dendrites, an electric pulse runs from neuron to neuron. That's all. Point. All the work of the brain on the fingers. How do we perceive the world with this thing? A signal came from the senses, was processed by nerve clusters, and the brain gave out a picture. The eardrum is shaken with a certain force and amplitude, one signal, another force, another signal. A light beam hits the retina of the eye, rods and cones are excited, and a signal is sent to a certain nerve cluster. The nerve signal is absolutely not specific, it is impossible to distinguish the nerve signal from the eye or from the eardrum in isolation from the sensory organs. All the great diversity of our world in the brain is perceived as a nerve impulse processed by the brain. So can we objectively perceive the world around us? Probably not. The point of view of a colorblind person and a person without color blindness do not differ from each other. Therefore, the Kantian expression “thing-in-itself” is relevant.
