Scientists make breakthrough in understanding stress
A team of neuroscientists has made a breakthrough in understanding how the brain responds to traumatic events.
The discovery could lead to new treatments for stress-related psychiatric disorders.
Dr Robert Pawlak, from the University of Leicester, said: "It was known certain individuals are more susceptible to detrimental effects of stress.
"However, the reasons were not clear."

Researchers, led by Dr Pawlak, found that the emotional centre of the brain – the amygdala – reacts to stress by increasing production of the protein neuropsin.
This triggers a series of chemical reactions including activating a gene that determines the stress response.
Blocking those proteins reduced stress levels.
Dr Pawlak said: "We are tremendously excited about these findings. Our discovery opens new possibilities for the prevention and treatment of stress-related psychiatric disorders such as depression and post-traumatic stress disorder."

“- I know what you mean, Kulgan...
when I've completed our regular supermarket shopping trip, one of the thoughts that often crosses my mind is that these people who cannot manoeuvre a trolley with any consideration for others will be driving a vehicle on the roads with the same aplomb... scary.”

“I understand Stress.
This morning I took my Mother shopping in Asda Hinckley (other supermarkets are available) for her weekly shop . It was horrendous. There must have been 5 million people doing their shopping (may be exagerating slightly ;) ) but it was full to the rafters.
The shop is only closed on Easter Sunday!!!
When I got home to Castle Crydee, the stress went away ;)”

“Thank You! A reason for funding universites research, whilst we do not agree with student Fees this work would be differcult if they were having to chase funding to do their research!”
