Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

842
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Plasticity00:58

Plasticity

2.5K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Neuroplasticity01:01

Neuroplasticity

669
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

271
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Psychosurgery01:30

Psychosurgery

94
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Introduction to Biological Bases of Psychology

3.4K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

Summary

This study introduces a new model for psychopathology using canalization. It proposes that pathological phenotypes develop as a defensive response, but can be countered by Temperature or Entropy Mediated Plasticity (TEMP) and psychological support.

Area of Science:

  • Theoretical neuroscience
  • Psychopathology research
  • Computational psychiatry

Background:

  • Classical construct of canalization revived to model psychopathology.
  • Distinction between two forms of plasticity: TEMP and canalization.
  • TEMP relates to increased model variance; canalization to increased precision.

Purpose of the Study:

  • Propose a new model for the general factor of psychopathology.
  • Explain pathological phenotypes as a defensive response via canalization.
  • Investigate the adaptive vs. maladaptive nature of canalization.

Main Methods:

  • Theoretical framework integrating concepts of plasticity and precision.
  • Drawing parallels with Hebbian plasticity and Ising models.
  • Referencing basic and human neuroscience findings.

Main Results:

  • Pathological phenotypes emerge through canalization, increasing model precision as a defense against distress.
  • Canalization entrenches psychopathology by narrowing phenotypic possibilities.
  • TEMP, alongside psychological support, can counteract canalization.

Conclusions:

  • Canalization represents a defensive, albeit potentially maladaptive, mechanism in psychopathology.
  • TEMP offers a potential therapeutic avenue to reverse pathological entrenchment.
  • The model provides testable hypotheses for future empirical research.
