Our findings of the need of both LVA Ca2+ channels and Ih currents for the shunting effect of the Ih channels are interesting for schizophrenia research since both Ih and LVA Ca2+ channels, alongside serotonergic, dopaminergic, and cholinergic receptors, are products of risk genes of the mental disorder [104–106]. The gene discussed is CA2; the disease is schizophrenia.
