Incorrect Bitter taste discrimination is high because each bitter taste cell expresses only one bitter receptor. Incorrect A single olfactory sensory neuron typically expresses one receptor type. Correct Taste categories are encoded only by intensity, NOT by which pathway is activated. Incorrect MC7b23_f330
Which one of the following statements is FALSE of sensory coding principles (smell vs taste)?
Taste is commonly described using a small number of basic qualities (sweet, sour, salty, bitter, and umami). Incorrect Bitter perception is frequently treated as a danger signal, so fine bitter identity is NOT strongly separated. Incorrect Some taste qualities are carried by dedicated pathways that preserve category identity. Incorrect Olfactory signals are mixed into a single channel before the brain, which prevents odor discrimination. Correct A single olfactory sensory neuron typically expresses one receptor type. Incorrect MC4ad2_82b0
Which one of the following statements is TRUE concerning sensory coding principles (smell vs taste)?
Each olfactory sensory neuron expresses many different olfactory receptor genes at the same time. Incorrect Taste categories are encoded only by intensity, NOT by which pathway is activated. Incorrect Odor identity is lost before reaching the brain, so the brain receives only intensity information. Incorrect Odor identity is encoded by patterns of activity across many olfactory receptor types. Correct Bitter taste does NOT use receptors and occurs only by diffusion into taste cells. Incorrect MC7b23_ae8c
Which one of the following statements is FALSE of sensory coding principles (smell vs taste)?
Each odorant activates only one olfactory receptor, so odor identity uses a one odor to one receptor code. Correct Olfaction supports high discrimination partly because many receptors contribute to identity coding. Incorrect Many bitter sensing taste cells express multiple bitter receptors, which limits preservation of bitter identity at the periphery. Incorrect Taste is commonly described using a small number of basic qualities (sweet, sour, salty, bitter, and umami). Incorrect A single olfactory sensory neuron typically expresses one receptor type. Incorrect MC229d_9495
Which one of the following statements is FALSE concerning sensory coding principles (smell vs taste)?
Coexpression of multiple bitter receptors in the same taste cells reduces the ability to label many separate bitter stimuli. Incorrect Taste is commonly described using a small number of basic qualities (sweet, sour, salty, bitter, and umami). Incorrect Different odorants can be distinguished even when they share some receptors, because the overall activation pattern differs. Incorrect Taste categories are encoded only by intensity, NOT by which pathway is activated. Correct A single olfactory sensory neuron typically expresses one receptor type. Incorrect MC229d_2724
Which one of the following statements is FALSE concerning sensory coding principles (smell vs taste)?
Bitter perception is frequently treated as a danger signal, so fine bitter identity is NOT strongly separated. Incorrect Bitter identity is preserved at the periphery by one receptor per cell logic. Correct Different odorants can be distinguished even when they share some receptors, because the overall activation pattern differs. Incorrect A single olfactory sensory neuron typically expresses one receptor type. Incorrect Many odorants activate multiple receptors, producing a combinatorial code for odor identity. Incorrect MC4ad2_fbe6
Which one of the following statements is TRUE concerning sensory coding principles (smell vs taste)?
Bitter perception is frequently treated as a danger signal, so fine bitter identity is NOT strongly separated. Correct Taste identity is primarily encoded by combinatorial patterns across many receptor types, like olfaction. Incorrect Odor identity is lost before reaching the brain, so the brain receives only intensity information. Incorrect Bitter identity is preserved at the periphery by one receptor per cell logic. Incorrect Each odorant activates only one olfactory receptor, so odor identity uses a one odor to one receptor code. Incorrect
