abstract = {To reveal the neuronal underpinnings of sensory processing
deficits in patients with schizophrenia, previous studies
have investigated brain activity in response to sustained
sensory stimulation at various frequencies. This paradigm
evoked neural activity at the stimulation frequency and
harmonics thereof. During visual and auditory stimulation
that elicited enhanced or ‘resonant’ responses in
healthy controls, patients with schizophrenia displayed
reduced activity. The present study sought to elucidate the
cellular basis of disease-related deficits in sensory
resonance properties using mice heterozygous for the
schizophrenia susceptibility gene Neuregulin 1 (NRG1). We
applied repetitive whisker stimulation at 1–15 Hz, a range
relevant to whisking behavior in mice, and measured cellular
activity in the primary somatosensory cortex. At frequencies
where control mice displayed enhancements in measures of
response magnitude and precision, NRG1 (+/−) mutants
showed reductions. Our results demonstrate for the first
time a link between a mutation of a schizophrenia risk gene
and altered neuronal resonance properties in sensory
cortex.},
