Researchers Discover How Stress Restructures the Brain

Stress restructures the brain by halting the production of crucial ion channel proteins, according to research in mice recently published in JNeurosci. Stress harms the brain and body in profound ways. One way is by altering astrocytes, the brain’s housekeepers tasked with mopping up neurotransmitters after they’ve been released into the synapse. On the cellular level,…

MIT Develops Soft, Flexible Neural Implants That Can Be 3D Printed on Demand

New technique may enable speedy, on-demand design of softer, safer neural devices. Credit: Courtesy of the researchers Technique may enable speedy, on-demand design of softer, safer neural devices. The brain is one of our most vulnerable organs, as soft as the softest tofu. Brain implants, on the other hand, are typically made from metal and…

An Aspirin a Day Does Not Keep Dementia at Bay – No Difference Than Placebo

Taking a low-dose aspirin once a day does not reduce the risk of thinking and memory problems caused by mild cognitive impairment or probable Alzheimer’s disease, nor does it slow the rate of cognitive decline, according to a large study published in the March 25, 2020, online issue of Neurology®, the medical journal of the American…

Lactation Changes Electrical Signaling in Mom’s Brain – But It’s Reversible

The membrane voltage of TIDA neurons oscillates more during lactation (right). Credit: Thörn Pérez et al., JNeurosci 2020 Prolactin-controlling neurons in mice undergo reversible changes in how neurons communicate. Lactation temporarily changes how a mother’s neurons behave, according to new research in mice published in JNeurosci. Mothers experience profound changes in their body after giving birth,…

MIT Neuroscientists Identify “Landmark Code” in the Brain That Helps Us Navigate

MIT neuroscientists have identified a “landmark code” that helps the brain navigate our surroundings. Credit: Christine Daniloff, MIT Neuroscientists discover how a key brain region combines visual and spatial information to help us find our way. When we move through the streets of our neighborhood, we often use familiar landmarks to help us navigate. And…
