Summary

High plexus visibility may indicate a predisposition to schizophrenia. This study found increased plexus visibility in individuals with schizotypal traits, but not in controls, suggesting a potential biological marker for schizophrenia risk.

Area of Science:

Neuroimaging and Psychiatry
Biological markers of mental health

Background:

Schizophrenia is a complex mental disorder with potential biological underpinnings.
High plexus visibility has been proposed as a potential biological marker for schizophrenia diathesis.

Purpose of the Study:

To investigate the association between high plexus visibility and schizotypal traits in a college student population.
To determine if plexus visibility can serve as a biological marker for schizophrenia predisposition.

Main Methods:

Assessed plexus visibility in college students.
Compared visibility between individuals endorsing schizotypal traits (n=160) and normal controls (n=99).

Main Results:

High plexus visibility was observed in 22 (14%) of individuals with schizotypal traits.

Related Experiment Videos

None of the control participants (n=99) exhibited high plexus visibility.

Conclusions:

The findings support an association between increased plexus visibility and schizotypy.
High plexus visibility may represent a potential biological marker for schizophrenia risk.
