All Too Human: The Price We Pay for Our Advanced Brains May Be a Greater Tendency to Disorders
Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.... Read More...

Ritalin Drives Greater Connection Between Brain Areas Key to Memory and Attention
A new neuroimaging study reveals methylphenidate, better known as Ritalin, increases the level of dopamine available in the caudate. Along with increased dopamine levels, researchers also notice greater functional connectivity between the prefrontal cortex, hippocampus and precuneus, three areas of the brain associated with memory and attention....

Siblings of Children with ASD or ADHD Are At Elevated Risk of Both Disorders
According to a new study, siblings of children diagnosed with ASD or ADHD have an increased risk of being diagnosed with the disorders themselves. Researchers found the odds of being diagnosed with ASD were 30 times higher for those who had older siblings with autism, and 3.7 times higher for ADHD diagnosis.... Read More...
