Cross-Modal Plasticity Results in Increased Inhibition in Primary Auditory Cortical Areas

Figure 7

One example of the response of multisensory neurons to auditory and optic chiasm stimulation before and after blockade of inhibition by gabazine. (a) Before gabazine application, this multisensory neuron in XMAC responded to both auditory and optic chiasm stimulation but not to light stimulation. (b) The response type was not changed by gabazine application. (c) The mean spikes per trial before blockade of inhibition. Neither facilitation nor depression was found when auditory and optic chiasm stimulation (AOX) were given together. (d) The mean spikes per trial after blockade of inhibition. Neither facilitation nor depression was found when bimodal stimuli were given. Conventions as in Figure 6.
