Incorrect Odor identity is determined mainly by odorant concentration, NOT by receptor activation patterns. Incorrect MCffb8_1227
Which one of the following statements is FALSE regarding sensory coding principles (smell vs taste)?
Olfaction supports high discrimination partly because many receptors contribute to identity coding. Incorrect Odor discrimination can rely on different receptor activation patterns rather than a one odor to one receptor map. Incorrect Some taste qualities are carried by dedicated pathways that preserve category identity. Incorrect Bitter taste discrimination is high because each bitter taste cell expresses only one bitter receptor. Correct Bitter taste is often encoded as an aversive category rather than many distinct bitter identities. Incorrect MC25e8_e922
Which one of the following statements is TRUE of sensory coding principles (smell vs taste)?
Taste uses hundreds of receptor types to encode thousands of distinct taste identities like smell. Incorrect Each odorant activates only one olfactory receptor, so odor identity uses a one odor to one receptor code. Incorrect Olfaction supports high discrimination partly because many receptors contribute to identity coding. Correct Each olfactory sensory neuron expresses many different olfactory receptor genes at the same time. Incorrect Bitter identity is preserved at the periphery by one receptor per cell logic. Incorrect MC25e8_d891
Which one of the following statements is TRUE of sensory coding principles (smell vs taste)?
Taste coding often uses labeled line logic for categories like bitter, sweet, and umami. Correct Each olfactory sensory neuron expresses many different olfactory receptor genes at the same time. Incorrect Taste uses hundreds of receptor types to encode thousands of distinct taste identities like smell. Incorrect Smell uses only a small set of receptors, so most odorants activate the same receptor. Incorrect Odor identity is lost before reaching the brain, so the brain receives only intensity information. Incorrect MC25e8_c5d8
Which one of the following statements is TRUE of sensory coding principles (smell vs taste)?
Odor identity is lost before reaching the brain, so the brain receives only intensity information. Incorrect Odor identity is determined mainly by odorant concentration, NOT by receptor activation patterns. Incorrect An individual olfactory sensory neuron usually expresses a single olfactory receptor gene. Correct Bitter taste discrimination is limited because bitter uses photoreceptors rather than chemoreceptors. Incorrect Sweet and bitter activate the same dedicated pathway, so the brain cannot separate them. Incorrect MCffb8_8fb3
Which one of the following statements is FALSE regarding sensory coding principles (smell vs taste)?
Sweet and bitter activate the same dedicated pathway, so the brain cannot separate them. Correct Coexpression of multiple bitter receptors in the same taste cells reduces the ability to label many separate bitter stimuli. Incorrect An individual olfactory sensory neuron usually expresses a single olfactory receptor gene. Incorrect Bitter perception is frequently treated as a danger signal, so fine bitter identity is NOT strongly separated. Incorrect Smell can distinguish many stimuli because odor identity depends on a large receptor repertoire and pattern coding. Incorrect MC25e8_737d
Which one of the following statements is TRUE of sensory coding principles (smell vs taste)?
Each olfactory sensory neuron expresses many different olfactory receptor genes at the same time. Incorrect Odor discrimination can rely on different receptor activation patterns rather than a one odor to one receptor map. Correct Olfaction is low discrimination because it relies on labeled line coding for a few odor categories. Incorrect Taste uses hundreds of receptor types to encode thousands of distinct taste identities like smell. Incorrect Each odorant activates only one olfactory receptor, so odor identity uses a one odor to one receptor code. Incorrect
