Surprising insights into the role of autophagy in neuron
Autophagy protects our neurons in the brain, but for entirely different reasons than previously assumed, as researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) and Charité in Berlin have shown. When the scientists used a genetic trick to switch off autophagy-mediated ''cellular waste disposal'', they found elevated levels of the endoplasmic reticulum, which acts, among other functions, as a calcium store. This leads to elevated neurotransmitter release and, ultimately, to fatal neuronal hyperexcitability. (2020-11-05)

The gut trains the immune system to protect the brain
The membranes surrounding our brains are in a never-ending battle against deadly infections, as germs constantly try to elude watchful immune cells and sneak past a special protective barrier called the meninges. In a study involving mice and human autopsy tissue, researchers at the National Institutes of Health and Cambridge University have shown that some of these immune cells are trained to fight these infections by first spending time in the gut. (2020-11-04)

Hormone differences
During birth, hormones in the body surge in both mother and baby, sent along by the nervous system. These stress hormones are there to spur delivery and to help a baby adapt to living outside the womb. A new study finds how one is born can have an effect on the amount of stress hormones released at the time of delivery. For example, vaginal delivery had the highest presence of birth signaling hormones. (2020-11-04)

Do octopuses' arms have a mind of their own?
Octopuses are strange creatures, with three hearts, eight arms and a nervous system distinct from any other animal. These fiercely intelligent creatures are jam-packed with over 500 million neurons, but over two thirds of these neurons are located within their arms and body. Many scientists therefore think that octopuses' arms act independently from the brain, but a study in Current Biology suggests that an octopus' arms and brain are more connected than previously thought. (2020-11-02)

Sleep-deprived mice find cocaine more rewarding
Sleep deprivation may pave the way to cocaine addiction. Too-little sleep can increase the rewarding properties of cocaine, according to new research in mice published in eNeuro. (2020-11-02)

How octopus suckers "taste by touch"
Imagine if you could taste something simply by touching it. Octopuses can do just that with their unique ''touch-taste'' sense, made possible by the suction-cup-like suckers along each of their eight arms. Now, researchers reporting October 29 in the journal Cell have new evidence as to how this sensory ability works. The findings help to explain how octopuses, and perhaps other marine organisms, explore the seafloor by tasting objects underwater with a simple touch. (2020-10-29)

Touch and taste? It's all in the tentacles
Scientists identified a novel family of sensors in the first layer of cells inside the suction cups that have adapted to react and detect molecules that don't dissolve well in water. The research suggests these sensors, called chemotactile receptors, use these molecules to help the animal figure out what it's touching and whether that object is prey. (2020-10-29)

Findings shed light on the ancient origins of speed control during movement
Movement in animals is complex. Little has been known about how spinal inhibitory interneurons work to silence other neurons and related muscle groups in coordination with the active muscle groups across changing speeds. Now a Northwestern University research team has discovered in a study of zebrafish that there is a very orderly relationship between when these critical inhibitory neurons are born, their participation in different speeds of movement and what part of a motor neuron they innervate. (2020-10-22)

New dimensions in the treatment of muscle spasticity after stroke and nervous system defects
Chronic muscle spasticity after nervous system defects like stroke, traumatic brain and spinal cord injury, multiple sclerosis and painful low back pain affect more than 10% of the population, with a socioeconomic cost of about 500 billion USD.
