White mars by Brian W. Aldiss & Roger Penrose. Chapter 14, 15, 16

It was these latter remotes that detected an area of disturbed neurotransmitters. They moved into the region and began to activate the groupings involved. Here they entered the large-scale quantum coherences that are essential to the generation of consciousness.

On the screens where the neuroscientists, Willa and Vera, watched, pictures and actions became evident. The skill of the women lay in interpreting the pictures as the remotes fired adjacent synapses.

‘Slightly viridian,’ said Willa.

‘Needs fewer fibres,’ said Vera. They had their own slang for what they did. ‘We’re getting coherency.’

Specific tightly interconnected groups of neurons acted coherently as a single unit. The validity of these groupings was sustained by a coherent quantum-mechanical process, like that of a superconductor or superfluid.

With tuning, the fibres sank back to form a huge black anatomy, its head hardly visible. Screaming cream things wavered in the background. A pudding cowered in a puddle.

Home life of Bevis Paskin Peters, aged three. Perception, as someone had said, was all. The sun was square and permeated by fish.

The Composite caught a signal from a remote homing in on the amygdala. They checked its programme. Here, deep in the limbic brain, wavered a primitive recollection. It had remained there, undiminished by time, since electrical resistance diminishes to zero in the HTC structures located there, much like the similar high temperature superconductors in our electrical cables.

Although a good theoretical understanding of ordinary superconductivity had been established halfway through the previous century, a proper understanding of HTCs had to wait until the early years of the twenty-first. This understanding had been put to important use in the new brain sciences. The neuron probe began to participate in the collective quantum state, showing a blur on the mentatropy screen which refined itself into an interpretable picture.

Pressures created an oval viewing like a squeezed lemon. Again a monster male, shouting and raving in deeper than viridian, the waves of anger misshaping it. The monster loomed over a limp white worm. Pale in pink the helpless something fluttered what might have been a hand.

The two separate remote fleets activated their groupings. The effects of quantum entanglement began to manifest themselves. The patient’s anciently stored pain became now.

A door of jelly slammed and wiped the oval all away.

‘He resents us,’ murmured Willa. ‘We’ll rest him and try again.’

It took expertise, but Willa-Vera interpreted the code to recognise in the white worm the being that would later grow to become the huge black body, the parent.

‘Father dominant,’ muttered Vera. ‘Son wishing to be father?’

I could contain myself no longer but said I hardly understood what was going on.

‘Basically, it’s fairly simple,’ said the fragile Willa Mendanadum, standing on tiptoe in her eagerness to explain. ‘Our remotes are travelling in areas where the effects of quantum state-reduction first become important. That’s where a quantum superposition actually becomes one of the classical alternatives. In fact, it appears that the entire phenomenon of consciousness is activated only when certain such quantum-coherent states begin to resolve into these classical alternatives.’

‘But I don’t know what you mean by classical alternatives!’ I wailed.

‘Oh, that’s simple too,’ Vera White said, with a knowing smile at her partner. ‘Imagine the nebulous borderline between the quantum and classical levels of physical activity, right? This has to do with the measurement problem of quantum mechanics: why is it that when we measure a quantum system we get one answer or another – the classical alternatives – instead of a quantum superposition of alternatives, which are an inherent part of the quantum-mechanical description of nature?’

I shook my head, feeling foolish.

‘Well, you see, when an observer steps in, the rules change. The standard quantum-mechanical procedures are interfered with! So what effect does the observer have? Why, quantum state-reduction comes in, and one thing or another happens, as Willa has said.’

She turned to her little partner. ‘Ready for another probe? Try coordinates between D60 and – let’s open E75.’

They peered into their spec-monitors. Behind them, paralysed but aware, strapped on the couch while the picoprobes toured his brain, lay Peters, screaming without sound.

Mentatropy, which would eventually hunt down his terrors and weaknesses and eradicate them, was not an easy option.
