The method uses functional MRI (fMRI) and diffusion tensor magnetic resonance imaging (DTI) to scan the brain, and data crunching software to interpret the data. The researchers hope that the finding will help parents and therapists uniquely identify which learning tools are best for each child. From the announcement by Vanderbilt University : The 45 children who took part in the study ranged in age from 11 to 14 years old. Each child first took a battery of tests to determine their reading abilities. Based on these tests, the researchers classified 25 children as having dyslexia, which means that they exhibited significant difficulty le...

In this post it’s used as having an adaptive system that uses exposure to stress to provide resistance to future negative events. Stress can lead to depression accompanied by atrophy and loss of neurons in the adult hippocampus in experimental studies. The effect of stress or whether you can become depressed due to stress seem to depend on individual characteristics. One characteristic is gene expression. Is it in your genes? Caspi et al showed that the 5-HTT genotype (serotonin transporter gene) moderates the depressogenic influence of stressful life events. It moderated the effect of life events that occurred not just in adulthood but also of stressful experiences that occurred in earl...

A significant reduction in FA was observed in the rostrum of the CC in patients with OCD compared with the rostral FA in the control subjects. (FA-Fractional anisotropy). Study results support the widely held view that the orbital prefrontal region is involved in the pathophysiology of OCD and indicate that the orbitofrontal circuit influences symptom severity in patients with OCD.

Lindner Center for Autism, North Shore-Long Island Jewish Health System in Bethpage, N.Y. found that there were increased areas of gray matter in the brains of children with autism.Using a new imaging technique researchers found autistic children had increased gray matter in the parietal lobes which has previously been implicated in the mirror neuron system. Mirror neurons are brain cells that are active when an individual is performing and action and experiencing an emotion or sensation and when the person witnesses the same actions, emotions and sensations in others. This system allows humans to learn by seeing as well as by doing.The study consisted of 13 male patients with high-functioning autism or Asperger syndrome with an IQ over 70 and 1...
