Posterior parietal cortex modulates perceptual decisions depending on psychotic phenotype.

Neuropsychologia - 15 Feb 2026

Scaramozzino Francesco, McKay Ryan, Furl Nicholas

Abstract excerpt

BACKGROUND: Reduced data-gathering and altered sensory precision are associated with psychotic phenotypes in tasks engaging the posterior parietal cortex (PPC). We investigated whether PPC excitability - modulated via 1 Hz repetitive transcranial magnetic stimulation (TMS) - differentially affects these behavioural patterns in high vs. low psychotic phenotypes. Based on prior work, we hypothesised that delusional...
