Scientific Objections: Even on the purely biological plane there is a wide, unbridgeable chasm between man and beast, as illustrated by the following four considerations: 1  The human brain possesses qualities [G2, p. 115â130] that have no parallel in the animal world. One consequence is manâs explicit mental capabilities.
Olfactory System. The olfactory system is responsible for our sense of smell. This sense, also known as olfaction, is one of our five main senses and involves the detection and identification of molecules in the air. Once detected by sensory organs, nerve signals are sent to the brain where the signals are processed. Our sense of smell is closely linked our sense of taste as both rely on the perception of molecules. It is our sense of smell that allows us to detect the flavors in the foods we eat. Olfaction is one of our most powerful senses. Our sense of smell can ignite memories as well as influence our mood and behavior. Olfactory System Structures. Our sense of smell is a complex process that depends on sensory organs, nerves, and the brain. Structures of the olfactory system include:
1. One reason this might be has to do with the way your brain processes odors and memories. Smells get routed through your olfactory bulb, which the smell-analyzing region in your brain. Itâs closely connected to your amygdala and hippocampus, brain regions that handle memory and emotion. The close connection may explain why a scent might get tied to vivid memories in your brain, and then come flooding back when youâre exposed to that particular odor trigger. As noted by Psychology Today: 2. âInterestingly, visual, auditory (sound), and tactile (touch) information do not pass through these brain areas.
