Mapping the Controllosphere

Project description

Mapping the brain’s hidden cost of thinking

Why does thinking hard feel hard? Mental effort shapes everything from learning to decision-making. It also plays a key role in conditions such as ADHD and depression. Yet scientists still do not fully understand why. The ERC-funded CONTROLMAP project aims to test a bold new theory: that cognitive effort reflects how much energy the brain spends to move between mental states. Using artificial neural networks, control theory, and brain imaging, researchers will map the brain’s ‘controllosphere’ – the regions that demand the most effort. The results could transform how we understand motivation, mental fatigue, and even inspire more energy-efficient AI systems.

Objective

"The sensation of cognitive effort is integral to everyday human experience, is a core construct in psychological theories of behavior, and contributes to multiple psychiatric disorders like ADHD and depression. However, despite decades of study the neural origin and functional purpose of cognitive effort remain poorly understood. This constitutes one of the most important outstanding questions in cognitive neuroscience and a major challenge to mental health research.

Recently, I proposed a new, mathematically formal theory of cognitive effort that draws together concepts from dynamical systems analysis, linear control theory (LCT), artificial neural networks (ANNs), cognitive psychology and neurophysiology. The theory relates cognitive effort to the fact that brain neuroanatomy and neurophysiology render some neural states more energy-efficient than others. In particular, I introduced the concept of the ""controllosphere,"" an energy-inefficient region of neural state space associated with high cognitive control, and proposed that cognitive effort serves to move the system state out of this high-energy region.

The goal of this project is to test the controllosphere theory. I will use ANNs to simulate human behavioral and neural data collected in tasks that require mental effort, and apply LCT to these models to make formal predictions about which neural representations are more or less effortful. I will then test these predictions using a wide variety of empirical techniques in a series of experiments with human participants. The establishment of a verified formal theory of cognitive effort will fill an important gap in the cognitive neuroscience of cognitive control, strongly impact clinical practice, and provide important insights for the development of novel artificial intelligence systems that balance computational function against energy use.
