چکیده انگلیسی
The recent characterization of excitatory and inhibitory synaptic receptive fields in rat auditory cortex laid the basis for further investigation of the roles of synaptic excitation and inhibition in cortical computation and plasticity. The mouse is an increasingly important model system because of the wide range of genetic tools available for it. Here we present the first in vivo whole-cell voltage-clamp measurements of synaptic excitation and inhibition in the mouse cortex. We find that a substantial population of auditory cortical neurons receives balanced synaptic excitation and inhibition, whose amplitude ratios and relative time courses remain approximately constant across tone frequency. We conclude that the synaptic mechanisms underlying tone-evoked auditory cortical responses in mice closely resemble those in rats, supporting the mouse as a suitable model for synaptic processing in auditory cortex.
