Brain Energy Mismatches in Schizophrenia
A new study explores the potential role of energy bottlenecks in brain cells in explaining fragmented experiences of time, space, and self in schizophrenia.
A recent study published in Neuroscience and Biobehavioral Reviews suggests that an energy bottleneck in brain cells may limit the brain's ability to maintain synchronized rhythms, contributing to fragmented everyday experiences in people with schizophrenia-spectrum conditions. The model proposes that inadequate adjustment of energy support might limit the brain's ability to coordinate activity as demands change, leading to differences in how individuals perceive and experience time and space. This hypothesis is based on evidence from cell studies, metabolic imaging, and functional brain imaging, which indicate that brain cells in schizophrenia may struggle to increase energy production when demand rises. Laboratory stem-cell models show that cells in schizophrenia maintain normal baseline energy production but have reduced spare respiratory capacity, limiting their ability to increase energy production when demand rises (source ID: 1). [1]
The study also highlights that people with schizophrenia often show weaker power and phase synchronization of brain activity in 40-Hz auditory rhythms, which are important for maintaining neural coordination. Neuroimaging studies suggest that intrinsic neural timescales (INTs), the brain's internal memory windows, are also less adaptable in schizophrenia, making it harder to adjust them when switching from rest to active tasks. These energy-related changes may also disrupt brain rhythms, contributing to the fragmented experience of time, space, and self (source ID: 1). [1]
To test this hypothesis, the author proposed experiments that combine real-time brain wave recordings (EEG) with metabolic brain imaging (fPET) as participants listen to a rhythmic 40-Hz sound. The tests would examine how the brain produces and uses energy, how it responds to changing demands, and the relationship between energy metabolism and neural activity. The researcher proposed a three-part strategy to turn the idea into testable parameters, including a multimodal experiment that pairs PET scans of glucose uptake with high-speed brain wave recording (source ID: 1). [1]
The study, titled 'Disrupted metabolic support of intrinsic brain rhythms as a driver of spatiotemporal fragmentation in schizophrenia,' was published in the journal Neuroscience & Biobehavioral Reviews in 2026. The research was conducted by Mário Jorge Cunha and focuses on the neural and metabolic mechanisms underlying altered perceptions of time, space, and self in schizophrenia-spectrum conditions. The article is available at the DOI: 10.1016/j.neubiorev.2026.107007. The study builds on prior findings from cell studies, metabolic imaging, and functional brain imaging, and it proposes a unified model based on these data. The research is part of an ongoing effort to understand the biological basis of schizophrenia and related conditions, with implications for future clinical and therapeutic approaches. [1]

The proposed experiments aim to test the hypothesis of an energy bottleneck by combining real-time brain wave recordings (EEG) with metabolic brain imaging (fPET). Participants are exposed to a rhythmic 40-Hz sound, and their brain activity is monitored as they listen to the sound at varying levels of demand—low, medium, and high. This method allows researchers to observe how the brain's energy supply and wave synchronization respond to increasing mental workload. The study's location is not explicitly stated in the source, but it is likely conducted in a neuroscience research laboratory equipped with advanced neuroimaging technologies. The project scope includes both experimental design and future clinical studies, with the goal of validating or refuting the energy adaptation bottleneck theory. [1]
The study notes that laboratory stem-cell models have shown that brain cells in schizophrenia maintain normal baseline energy production but have reduced spare respiratory capacity. This reduction limits their ability to increase energy production when demand rises, as evidenced by a 15% to 22% drop in creatine kinase reaction kinetics. These findings suggest a potential link between impaired energy metabolism and disrupted brain rhythms, particularly in the 40-Hz auditory frequency range. The research also highlights that neuroimaging studies have found less adaptable intrinsic neural timescales (INTs) in schizophrenia, which may contribute to difficulties in adjusting to changing cognitive demands. These documented limits provide a framework for understanding the biological underpinnings of altered spatiotemporal experiences in schizophrenia. [1]

A 15% to 22% drop in creatine kinase reaction kinetics points to slower ATP transfer between brain cells (source ID: 1). [1]
