Neuroimaging Advances for Depression

While neuroimaging for depression have made strides in recent years, no findings have been sufficiently replicated or considered significant enough to warrant application in clinical settings. Our authors tell us what the future may bring.

Matthieu Ricard and‎ Wolf Singer’s Beyond the Self: Conversations between Buddhism and Neuroscience

Book Review

In this book review, two friends, one a Buddhist monk trained as a molecular biologist, and the other, a distinguished neuroscientist—offer their perspectives on the mind, the self, consciousness, the unconscious, free will, epistemology, meditation, and neuroplasticity.

Microglia: The Brain’s First Responders

Microglia help guide brain development and serve as immune system helpers. These cells may hold the key to understanding not just normal brain development, but also what causes a number of intractable brain disorders.

The First Neuroethics Meeting: Then and Now

On the 15th anniversary of the Neuroethics: Mapping the Field conference in San Francisco, we asked three of the original speakers to reflect on how far the neuroethics field has come in 15 years—and where the field may be going in the next 15.

The Illusion of the Perfect Brain Enhancer

Many questions loom over transcranial direct current stimulation, a non-invasive form of neurostimulation in which constant, low current is delivered directly to areas of the brain using small electrodes.

Olfaction: Smell of Change in the Air

Scientists studying smell have not only provided compelling evidence that it’s more sophisticated than previously thought, but believe that the sense of smell impacts our mood and behavior and has the potential to detect and treat some neurological disorders.

The Brain’s Emotional Development

New research is helping scientists learn about areas that are crucial to the brain's emotional development, and how our surroundings fit into the picture. The findings could have far-reaching implications for both parents and policy-makers.

The Sleeping Brain

While scientists believe that sleep re-energizes the body's cells, clears waste from the brain, and supports learning and memory, much still needs to be learned about the part it plays in regulating mood, appetite and libido.

Genetics and ALS: Cause for Optimism

While drug development has done little to slow the devastating symptoms of amyotrophic lateral sclerosis (ALS), there is some good news in the fact that scientists have identified some 100 related genes and believe that genetic research offers the best hope for treatments.

Gut Feelings on Parkinson’s and Depression

Sometimes referred to as the “second genome” or the “second brain,” scientists now believe that the microbiota, the collective bacteria, viruses, fungi and other microorganisms that live in the digestive tract, may be a way to treat any number of disorders, including Parkinson’s disease and depression.
