TRPV1 and schizophrenia: Given that abnormal motor-evoked potentials and pain sensitivity are observed in schizophrenia patients (Pascual-Leone et al., 2002; Bonnot et al., 2009; Lakatos et al., 2013; Zhou et al., 2016), TRPV1 channels—and therefore the endovanilloid system—could be altered in schizophrenia, which deserves neurophysiological investigation.
