Each year, the initiative celebrates some standout and especially creative examples of such advances in the “Show Us Your BRAINs! Photo & Video Contest. During most of August, I’ll share some of the most eye-catching developments in our blog series, The Amazing Brain.

Researchers supported by the National Institutes of Health Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative have developed a way to genetically insert a type of light receptor into neurons. The new technique enables the researchers to suppress the neuron’s activity using pulses of light. While researchers have previously used light to control the activation of neurons, the ability to inhibit the activity of neurons represents a powerful tool that can be used to better understand the workings of neural circuits in the brain.

In the diagnosis of disease, doctors often need to take tissue samples and process them for examination under a microscope. Millions of such biopsies are performed in the U.S. every year. But these pose many challenges. Biopsies may damage healthy tissue. Conventional histology techniques used to examine the samples can require extensive processing and take days.

NIH-funded study identifies brain cells that form boundaries between discrete events.

Treatment-resistant depression (TRD) is diagnosed after an individual has tried several types of treatment for depression and their symptoms haven’t improved. The effectiveness of deep brain stimulation (DBS) as a treatment for disorders such as Parkinson’s disease has led researchers to investigate whether it could also work for psychiatric disorders such as TRD. However, depression varies significantly among individuals, and studies on DBS for TRD have also produced variable results. This points to a need to personalize DBS treatment for individuals with depression.

Study sheds light on potential for long-term, at-home use of deep brain stimulation as a treatment for neuropsychiatric disorders
