Stimulation of Dorsolateral Prefrontal Cortex Enhances Adaptive Cognitive Control: A High-Definition Transcranial Direct Current Stimulation Study Oyetunde Gbadeyan, Katie McMahon, Marco Steinhauser and Marcus Meinzer Journal of Neuroscience 14 December 2016, 36 (50) 12530-12536; DOI: https://doi.org/10.1523/JNEUROSCI.2450-16.2016

A cutting edge, non-invasive brain stimulation technique could improve cognitive control for people with conditions such as schizophrenia and autism, ADHD. Researchers at The University of Queensland’s Centre for Clinical Research have found the technique – which applies high-definition transcranial direct current stimulation to a particular area of the brain – improves cognitive and conflict control.

PhD candidate Oyetunde Gbadeyan said the study provides th...

University of Virginia School of Medicine researchers have determined that the immune system directly affects and even controls, creatures’ social behavior, such as their desire to interact with others. So could immune system problems contribute to an inability to have normal social interactions? The answer appears to be yes, and could have great implications for neurological conditions eg autism-spectrum disorders and schizophrenia.

“The brain and the adaptive immune system were thought to be isolated from each other, and any immune activity in the brain was perceived as sign of a pathology. And now, not only are we showing that they are closely interacting, but some of our behavior traits might have evolved because of our immune response to pathogens,” explained Jonathan Kipnis, PhD...

A team of scientists from across the globe have shown that the brains of patients with schizophrenia have the capacity to reorganize and fight the illness. This is the first time that imaging data has been used to show that our brains may have the ability to reverse the effects of schizophrenia. Schizophrenia is an illness generally associated with a widespread reduction in brain tissue volume. However, a recent study found that a subtle increase in tissue also occurs in certain brain regions.

The study followed 98 patients with schizophrenia vs 83 patients without schizophrenia...

A new Salk study is the first to closely follow the development of new neurons in the adult brain, giving insight into neurodevelopmental disorders such as autism and schizophrenia.

A new study is first to closely follow development of new neurons in the adult brain, giving potential new insight into neurodevelopmental disorders such as autism and schizophrenia. New brain cells began with a period of overgrowth, sending out a plethora of neuronal branches, before the brain pruned back the connections. “We were surprised by the extent of the pruning we saw,” says Prof. Rusty Gage.

While most o...
