Lions and Tigers and Bears....Oh my....

Scientists at the Salk Institute are trying to figure out how fear and anxiety work, with a worm.  The worm is small and called a nematode.  It was soaked in a chemical, called a sulfolipid, that induces an avoidance reaction.  The chemical is from the worm's natural predator.  They used this worm because it is so simple and they could measure the 302 neurons.  When the worm was then soaked in Zoloft the fear reaction (not laying eggs) stopped. 
Scientists have been trying to figure out how the fear response is created for the last 30 to 40 years, using mice and other creatures.  Because each person's response is different they have found it difficult to find the neural pathways that create the response to fear or anxiety. 
It is estimated that 1 in 6 Americans take a psychiatric drug.  The clinical response to these drugs get mixed results. 

Try LENS neurofeedback.  It can help you to get off of the drugs to create a better, balanced brain environment.
