Uncovering the role of somatostatin signaling in the brain

Somatostatin, a signaling molecule produced by many inhibitory neurons in the brain, broadly dampens communication among a variety of cell types in the prefrontal cortex and promotes exploratory and risk-taking-like behavior ...

Exploring how psychedelic drugs affect a rat's brain

Researchers at Lund University have developed a technique for simultaneously measuring electrical signals from 128 areas of the brain in awake rats. They have then used the information to measure what happens to the neurons ...

Fiber-infused ink enables 3D-printed heart muscle to beat

Over the last decade, advances in 3D printing have unlocked new possibilities for bioengineers to build heart tissues and structures. Their goals include creating better in vitro platforms for discovering new therapeutics ...

Portable, low-cost tech tracks uterine contractions

Keeping track of pregnancy requires a dizzying array of gargantuan and expensive machines. An MRI machine is the size of a room and can cost up to $1 million. But the care such equipment provides is a critical part of prenatal ...

Neuroscience

4D printing allows flexible electrodes for nerve stimulation

Specific nerves may be stimulated artificially, for example to treat pain. The finer the nerves, the more difficult it is to attach the required electrodes. Researchers at the Technical University of Munich (TUM) and NTT ...

Neuroscience

Study identifies novel regulators of hippocampal overactivity

Reduced expression of specific calcium channels impaired electrical signaling between neurons and contributed to the onset of behaviors associated with neurodevelopmental disorders and seizure susceptibility in mouse models, ...

Neuroscience

How synaptic vesicles accumulate glutamate

In the brain, neurons communicate via neurotransmitters, which trigger electrical signals in downstream neurons by binding and activating specific receptors. Neurotransmitters are released through the fusion of synaptic vesicles, ...
