<p>So far, the scientific community has been surprised by how sensitive the sensory organs may be, but new research by neuroscientists at <strong>Rutgers University</strong> has found that <strong>fear</strong> of certain odors occurs even before such odors are <strong>processed by the brain</strong> . </p>
<h2><strong>Pre-Awareness Learning</strong></h2>
<p>Dr. John McGann and his colleagues have revealed - after a study of genetically engineered mice - that the noses of these animals reacted strongly to arousing <strong>feelings of fear</strong> , even before the odor signals are interpreted by the brain.This comes to dismantle the tendency we had to think that learning was something that only occurred in the depths of the brain, and only after crossing the field of consciousness. McGann himself states: </p>
<blockquote>"Now we see how the nervous system can become especially sensitive to threatening stimuli and how fear can completely permeate the signals on its way from the sensory organs to the brain."</blockquote>

<h2><strong>Increased understanding of post-traumatic stress and anxiety</strong></h2>
<p>Researchers have deduced that the sensory process discovered indicates that fearful memories can influence and condition the senses. In turn, this influence could be very useful to better understand diseases so common in our time, as the post-traumatic stress disorder. In this, they manifest heavy symptoms of anxiety and unfounded fears, although the person is not in danger.</p>
<p>In this sense, McGann explains that post-traumatic stress disorders - especially in soldiers affected by this disease - are triggered by odors such as diesel emissions. The high sensory capacity of the recent study provides a new way of thinking about how these anxiety reactions occur, and how they could be treated more effectively.</p>
<p>During the study, mice that were traumatized by shock showed a much greater sensitivity to odors. These odors caused the olfactory nerve to increase significantly the amount of neurotransmitters released by the brain cells. <br>
Scientists saw that brains may be hypersensitive to <strong>scents associated with fear</strong> . </p>

<h2><strong>Reverse to heal</strong></h2>
<p>Dr. McGann clarifies that what has been concluded so far by the investigations is of great importance, but adds that the studies will continue with a view to determine whether <strong>hypersensitivity to danger</strong> through odors can be reversed by using shock therapy or exposition. This is intended to show the mice that such odors are not associated with any danger. The ultimate purpose of this reversal is to verify whether new therapeutic treatments can be introduced to treat anxiety in humans.What do you think of these conclusions ? Do you want to know more about <strong>how fear manifests</strong> ? </p>
