New insights into how inhibitory neurons contribute to functional networks in the cortex
Networks consist of many types of neurons, including some that send excitatory signals, increasing the likelihood of other neurons firing, and some that send inhibitory signals, decreasing the likelihood of other neurons firing. Researchers at Max Planck Florida Institute for Neuroscience demonstrated that inhibitory neurons participate in finely-tuned, functionally-specific networks, similarly to excitatory neurons. Researchers suspect that abnormalities in these networks may play a role in a variety of brain disorders. (2017-03-08)

Giving up cigarettes linked with recovery from illicit substance use disorders
Smokers in recovery from illicit drug use disorders are at greater risk of relapsing three years later compared with those who do not smoke cigarettes.

Bursting pods
Plants are capable of producing powerful movement that is initiated at the molecular level. This fast motion is often supported by helix-based architectures, for example in vetches or orchids that spread seeds by explosive opening of their pods. Researchers now demonstrate in the journal Angewandte Chemie that these biological strategies can be re-engineered by interfacing molecular switches with man-made materials. (2017-02-15)

Is it depression or dementia? Brain SPECT imaging helps distinguish them
Does a patient have depression or a cognitive disorder (CD) such as Alzheimer's disease or both? Since both disorders have overlapping symptoms, how can a clinician tell them apart to make an appropriate diagnosis? In a new article published in the Journal of Alzheimer's Disease, researchers have found that single photon emission computed tomography, or SPECT, can help to distinguish between these diagnostic categories. (2017-02-15)

When choosing your next move, your brain is always ready for plan B
Whether we're navigating a route to work or browsing produce at the grocery store, our brains are constantly making decisions about movement: Should I cross the street now or at the intersection? Should I reach for the red apple or the green apple? When you're presented with two options, your brain's motor neurons prep for both possibilities before you've decided which action to take, say researchers in a study published in the journal Cell Reports. (2017-02-14)

Both accelerator and brake are required for normal movement
In order to drive a car, you need a good balance between accelerator and brake. The same applies to a part of the brain -- the striatum -- that controls our movements. Research at Lund University in Sweden has led to new findings on the interaction between the 'accelerator' and the 'brake' in the striatum. These findings may guide the development of treatments for movement disorders such as those occurring in Parkinson's disease. (2017-01-27)
