Individuals with social phobia have too much serotonin - not too little

Individuals with social phobia have too much serotonin - not too little | enjoy yourself | Scoop.it

Previous studies have led researchers to believe that individuals with social anxiety disorder/ social phobia have too low levels of the neurotransmitter serotonin. A new study carried out at Uppsala University, however, shows that the situation is exactly the opposite. Individuals with social phobia make too much serotonin. The more serotonin they produce, the more anxious they are in social situations.

Kenneth Weene's insight:

There is no subject I enjoy learning more about than neurobiology, but I keep wondering when those brain scientists will understand that the brain is filled with feedback loops, both amplifying and attenuating. To make believe that there is a simple pathway is to miss the whole glory of its functioning.

Why people with depression pay more attention to negative information

Why people with depression pay more attention to negative information | enjoy yourself | Scoop.it

People with depression process emotional information more negatively than healthy people. They show increased sensitivity to sad faces, for instance, or a weaker response to happy faces. What has been missing is a biological explanation for these biases. Now a study reveals a mechanism: an unusual balance of chemicals in a brain area crucial for the feeling of disappointment.

Kenneth Weene's insight:

Absolutely fascinating reading for those of us who have an interest in neuroscience.

Research suggest an evolutionary link between the disorder and what makes us human
Kenneth Weene's insight:

The price our species pays for the complexity of the human brain may well be the disorders of mind.

Scientists find new clues to brain's wiring

New research provides an intriguing glimpse into the processes that establish connections between nerve cells in the brain. These connections, or synapses, allow nerve cells to transmit and process information involved in thinking and moving the body.
Kenneth Weene's insight:

Always good to know that neuroscience is moving forward. I wonder if I would have gone into psychology if it had all this hard science available back then. Maybe, I would have gone directly to writing books. I like personality and behavior more than I like neuroscience. But I do love learning this stuff.

Two new studies further support the theory that our political decision-making could have a neurological basis.
Kenneth Weene's insight:

This is must reading if you are interested in politics. Of course, it may be that the part of the brain we use is a function of how we have taught ourselves to react to life so I don't want to get to het up about the causal implications.
