Exam 14: Olfaction: Perceiving Odors

The olfactory receptor neurons are embedded in the:

In a study conducted by Miller and Maner (2010), male college students smelled T-shirts that had been worn under different conditions by four women as they slept. Some of the T-shirts had been worn by the women on the nights closest to ovulation, some on the nights farthest from ovulation, and some had never been worn. When the testosterone levels of the men were measured in the saliva samples:

The _____ cortex is the primary olfactory cortex.

Caio's olfactory sense picked up the smell of a particular food dish that he had not eaten recently. The smell caused him to remember events from the past. According to the studies on autobiographical memories, which decade of his life is Caio MOST likely to remember? Explain why.

Willander and Larsson (2006) studied autobiographical memories elicited by odors, words, or pictures for participants aged 65 to 80 years. They found that the feeling of being "brought back in time" was STRONGEST for participants in the _____ age group.

What is odor adaptation and cross-adaptation? Provide an example of each from your life.

Humans have approximately _____ different types of olfactory receptor neurons.

Which statement is TRUE of odorants?

Research has shown that the orbitofrontal cortex (OFC) is involved in:

Since the olfactory pathway includes the amygdala, orbitofrontal cortex, and the hippocampus, odor-evoked memories tend to be:

Stevenson et al. (2010) studied human responses to fecal and urinous odorants and found that:

Which statement is TRUE of the relationship between olfaction and cigarette smoking?

How would a person's sense of smell be affected if these brain regions were damaged: the olfactory bulb, the posterior piriform cortex, and the orbitofrontal cortex?

Mitral cells and tufted cells synapse with the olfactory receptor neurons in the:

Based on the use of contextual information, when dining out at a restaurant, which odor would be the EASIEST to identify?

The entorhinal cortex is the gateway to the _____, where long-term memories are stored and retrieved.

The small spherical structures in the olfactory bulb are called:

In many species, chemicals that would seem to qualify as pheromones are sensed via a _____ system.

Which subdivision of the piriform cortex produces representations of the features of odorant molecules?

The area of the brain that receives inputs from the piriform cortex and is involved in evaluating the pleasantness of stimuli is the:
