All human mental experiences, whether perceptual or conceptual are the result of natural processes, including neurotransmitters, operating within the unimaginable complexity of a living human brain.
Your reference to "clockwork and gears" wouldn't even begin to explain how digital computers work. Similarly, computer analogies are far too primitive to explain how "mind" can be an emergent property of a living brain.
Decades ago I worked for a pharmaceutical company which researched the nature of love and pair-bonding. Chimpanzees with remotely controlled infusion devices were shown a toy stuffed animal and were either given a dose of oxytocin or a placebo. After repeating several times a day for a few days, the toys were given to the chimps. Those who had received the placebo, simply ripped the toy to shreds, while those who had gotten the oxytocin treated their toy with tenderness and obvious affection. There have been several variations of the oxytocin experiments repeated by various researchers and all demonstrated that the hormone is associated with both affection and pair bonding. When intravenous injections were administered to paid human male volunteers, all reported sensations similar to the after-glow following orgasm. Oxytocin is released by the pituitary gland during orgasm. (Oxytocin has a profoundly different effect on females, causing the uterus to contract following childbirth and being associated with lactation and motherly love for her infant.)
It has long been known that males frequently fall helplessly in love with a regular lover, which is why monks and priests traditionally abstain from sexual activities, so as not to distract from or diminish their love of God. Even football coaches appreciate that sexual activity reduces aggression and determination in their players.
Neurophysiology is the scientific discipline which seeks to understand the means by which living brains create mental experiences. The first serious studies began only after the discovery of electrical activity within the brains of rabbits, about 1875, and with the invention of the triode amplifier tube, about 1906. Given that the human brain is the single most complex object known to exist, it is not surprising that its operation is still not adequately understood. It takes extremely intelligent and highly educated specialists decades of experience just to glimpse the beginnings of understanding how a brain can create a mind. There are even serious doubts as to whether a brain is capable of fully understanding its own complexity.
