The usual way to study the brains response to sounds is to have subjects listen to pure tones. The response to recognizable sounds may differ. To compare responses, researchers anesthetized macaque monkeys. They fed pure tones and also monkey calls directly to their brains by inserting electrodes. Response to the stimulus was measured by the firing rate (electrical spikes per second) of neurons in various areas of the brain. Table 18.2 contains the responses for 37 neurons. Researchers suspected that the response to money calls would be stronger than the response to a pure tone. Do the data support this idea?
