quiz 7 Flashcards
Humans are _____________, meaning they have a less keen sense of smell that is not crucial to survival.
microsomatic
In experiments with humans (Porter et al., 2007) and sharks (Gardiner & Atema, 2010), it was shown that odor localization could be accomplished by monitoring how odors (scent plumes) arrived at each nostril. The specific cue used in odor localization was compared to which of the following cues from auditory localization?
ITD
– when the odor reached one nostril earlier (time cue or ITD), this was associated with head turning in that direction.
Olfactory transduction takes place in the ____________________.
Olfactory mucosa
Although we cannot always tell how a chemical will be perceived by its molecular structure, it has been found that odorants cause patterns of activation in certain neurons. Using optical imaging and radioactive tagging, a ‘chemotopic map’ of odorants has been found in which structure in the olfactory system?
Olfactory bulb
The olfactory bulb sends signals to the ______________, which seems more involved in signal discrimination. From there, signals go to the _______________, which appears more responsible for pleasantness ratings and recognition.
piriform cortex; orbitofrontal cortex
Which of the structures below is considered a primary cortical receiving area for taste information?
There are two areas – the other one is the frontal operculum cortex.
Insula!!!!
Signals for taste and smell are combined in the _____________. This area also gets input from visual and somatosensory areas, contributing to the construction of what we perceive as flavor.
Orbitofrontal cortex
Taste buds are located in all of the tongue’s papillae except for which of the following?
Filiform
the insula is implicated
our representation of disgust and emotional states.
Loss of the ability to detect odors is called ____________.
anosmia
