FIGURE 3.10

Responses to glutamate receptor blockers recorded in vivo by extracellular recording from an rNST neuron. In the control recording, taste stimuli representing the four taste qualities were flowed over the tongue and the resulting response frequency of the neuron plotted as a peristimulus-time versus action potential frequency histogram. The glutamate receptor blockers APV and CNQX were then microinjected adjacent to the neuron and the tongue stimulation sequence repeated. APV had a minimal effect on this neuron, but CNQX blocked all excitatory input from the periphery and no responses were recorded from the neuron to any taste stimuli. (From Li, C. S. and Smith, D.
