SOUTH AFRICA – The University of Cape Town (UCT) Neuroscience Institute’s Professor Mark Solms has been awarded an Oppenheimer Memorial Trust grant of US$102,247( R1.9M).

The grant will enable a new line of inquiry into proof-of-concept research endeavors that seek to understand how and why consciousness works by using an artificial agent.

The grant will be awarded by the Oppenheimer Memorial Trust, a charitable organization that has been deeply committed to education in South Africa and has a long history of supporting UCT research programs.

The funding line will enable Professor Solms and his research team endeavor into new research avenues into consciousness and artificial intelligence (AI).

Funding of this nature allows for high-risk, high-reward research that is often passed up in favor of research that meets immediate needs or is disease-focused. 

The research has the potential to yield answers about what it fundamentally means to be human.

“We are extremely grateful to organizations such as the Oppenheimer Memorial Trust that empower our blue-sky research aspirations through such generous philanthropic funding,” acknowledged Prof. Solms. 

Professor Solms is the director of Neuropsychology at UCT’s Neuroscience Institut and has garnered international repute for his pioneering work in the fields of neuropsychology and affective neuroscience.

He is best known for identifying the brain mechanisms of dreaming and for integrating psychoanalytic insights with modern neuroscience. 

Prof. Solm is a previous recipient of the pre-eminent Harry Oppenheimer Fellowship and Medal, Solms has spent his entire career investigating the mysteries of consciousness. 

Discovering how subjective feelings arise from physical processes has been a lifetime’s quest.

Why UCT and Prof. Solms are delving into consciousness? 

Consciousness is the inner, subjective experience of the mind and is central to our daily lives. 

Many questions are yet to be answered on how and why it arises and remains one of the most intriguing questions in science. 

The search for the brain activity that underlies consciousness, known as the neural correlate of consciousness, has recently shifted focus from cortical structures and cognitive functions such as perception, learning, memory, and language to brainstem structures and affective functions such as emotion, feeling, and mood. 

This follows the novel hypothesis of Solms & Panksepp that the foundation of consciousness is brainstem arousal and modulation of cortical perception and action selection, and not the cortical functions themselves. 

Simply put, subjective feelings are the values that enable us to make voluntary choices that maintain physiological stability, otherwise known as homeostasis. 

Since the function of homeostasis was previously reduced to a series of algorithms, Solms & Friston reduced the extended homeostatic function of feeling to a further series of algorithms that can now be practically implemented, developed, challenged, and studied in an artificial agent.

A team of scientists, led by Solms, will endeavor to crack the code of consciousness through its replication and simulation in an artificial agent. 

Drawing on the team’s diverse expertise in neuropsychology, cognitive neuroscience, computational neuroscience, physics, applied mathematics, AI, and robotics, the goal is to design and evolve an artificial agent equipped with three conflicting categories of need, upon which its existence depends. 

These are the need to find energy resources; the need to avoid structural damage; and the need to recuperate through rest. 

The agent must learn to meet these needs by trial and error, followed by counterfactual planning, in changing, uncertain, and progressively complex environments.

“The question as to how physical processes cause subjective experience isn’t called ‘the hard problem’ for nothing, but what question could be more interesting? Considering that subjective experience exists, that it clearly is part of nature, the question must be answerable by ordinary natural-scientific means,” said Solms.
