Final answer:
The statement is false; each olfactory glomerulus receives input from one type of olfactory receptor, and this specificity helps us discriminate different odors.
Step-by-step explanation:
The statement that each olfactory glomerulus receives input from several types of olfactory receptors is false. In reality, each olfactory glomerulus in the olfactory bulb receives signals from one type of olfactory receptor. These receptors are specialized to detect specific odorants. Essentially, every type of olfactory sensory neuron expresses only a single type of receptor protein and sends its signals to a corresponding glomerulus that interprets one specific odorant. This organization is crucial for the discrimination of different odorants in the environment which then are interpreted by the brain as distinct smells.
