How Alcohol Addiction – and Abstinence – Remodel the BrainNews
Novel imaging technologies produce first whole-brain atlas at single-cell resolution, revealing how alcohol addiction – and abstinence – change neural physiology and affect previously unsuspected regions of the brain
A Bigger Hippocampus Doesn't Mean Better MemoryNews
When it comes to certain parts of the brain, bigger doesn't necessarily equate to better memory. According to a new study led by Michigan State University, a larger hippocampus, a curved, seahorse-shaped structure embedded deep in the brain, does not always reliably predict learning and memory abilities in older adults.
Exploring an Enigmatic Sea Monster’s GenomeNews
In 1857, the Danish naturalist Japetus Steenstrup linked the tell tales of ships being dragged to the ocean floor to the existence of the giant squid: A ten-armed invertebrate, that is credibly believed to grow up to 13 meters and weigh over 900 kg. Now, more than 160 years later, an international team of scientists have sequenced and annotated the genome of a giant squid.READ MORE
A new paper focuses on the operational functions needed to advance brain-inspired neuromorphic computing. It suggests that hybrid architectures composed of digital architectures, alongside a resurgence of analog architectures, made possible by memristors, which are resistors with memory that can process information directly where it is stored.READ MORE
The source of essential tremor – a movement disorder that causes involuntary trembling of the hands, arms, and head – has been enigmatic, impeding the development of effective treatments. Now a new study suggests the tremors are caused by overactive brain waves at the base of the brain, raising the possibility of treating the disorder with neuromodulation to calm the oscillations.READ MORE
In a new study, researchers discovered that rats with spinal injuries experienced changes to their gut bacteria and a rise in anxiety-like behaviour. When rats with spinal injuries were given fecal transplants from healthy rats, their behaviour--and gut bacteria--remained normal.
Researchers have identified a key mechanism underlying neuronal dysfunction in Angelman Syndrome, which could open up new avenues for treatment options.READ MORE
Researchers have found that amyloid-beta oligomers hijack norepinephrine signaling at brain neurons; this knowledge could pave the way for potential treatment with a pre-existing drug.READ MORE
A new study suggests that extremely rare, harmful genetic mutations present in healthy donors’ stem cells may be passed on to cancer patients receiving stem cell transplants.READ MORE
