Boltzmann's Theorem Revisited: Inaccurate Time-to-Action Clocks in Affective Disorders

Area of Science:

• Neuroscience
• Thermodynamics
• Chronobiology

Background:

• Timely goal-oriented behavior is crucial for survival and is influenced by experience.
• Affective disorders are associated with disruptions in signal processing and behavioral timing.

Purpose of the Study:

• To investigate the thermodynamic underpinnings of signal variability in affective disorders.
• To explore the role of clock genes, mitochondria, and cellular communication in time-to-action accuracy.

Main Methods:

• A multileveled approach examining molecular, cellular, and electrophysiological processes.
• Application of Boltzmann's theorem for thermodynamic conceptualization of brain function.
• Utilized logic gates to analyze communication deviations and compensations.

Main Results:

• Deviations from excitation-inhibition balance and wave decoupling observed in affective disorders, leading to wider signal variability.
• Clock genes fail to protect mitochondria from oxidative stress, impairing energy production for accurate time-to-action.
• Multilevel biological clocks exhibit reduced accuracy and responsivity in affective disorders.

Conclusions:

• Affective disorders are characterized by thermodynamic dysregulation affecting signal accuracy and time-to-action.
• Restoring excitation-inhibition balance and accurate timing may involve non-neural cells and the extracellular matrix.
• Reversibility towards healthier timing and reduced entropy is thermodynamically implied.
