Hunger makes you better: Neural circuits in the brain drive improved physical performance and heightens motivation
An international team of researchers identified the neural circuit that dictates whether you will persevere or give up. This neural circuit may be responsible for why people perform better when they are hungry. The researchers conducted their study using fruit flies and found a small region in their brains that became highly active when the flies were starved. “Our experiments show […]

Forgotten dreams: REM sleep helps prevent information overload, explain scientists
Dreams are quickly forgotten the moment people wake up. This is likely due to a group of neurons that gets activated during rapid eye movement (REM) sleep – the phase of mammalian slumber when most dreams are made. A recent study published in the journal Science examined the neurons that produce appetite and sleep hormones in mice. Japanese and American […]

Why do sufferers of Alzheimer’s nap so much? Study suggests the disease kills the cells needed to stay awake
A study published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association found that in people with Alzheimer’s, tau proteins promote the degeneration of brain regions responsible for keeping people awake. This explains why excessive daytime napping is common among people with the disease and suggests that it could be an early sign of Alzheimer’s. Previous studies have explored […]

Immune cells ATTACK the aging brain and release a substance that hinders new nerve cell production, report scientists
One of the defining features of the brain that sets it apart from all other organs of the human body (except muscles) is that it is made up of cells that cannot regenerate. The nerve cells in the brain called neurons are terminally differentiated, meaning that, unlike skin cells or blood cells, they cannot reproduce. So […]

Optogenetics and your brain: Researchers study the therapeutic potential of light
Can light restore vision to blind people and help treat paralysis in patients with Parkinson’s disease? German researchers have recently examined the possibility of stimulating light-sensitive proteins to achieve therapeutic effects on various health conditions. Optogenetics is a technique that manages processes in the brain through light-based stimulation. It achieves its effects through light-controlled proteins […]

Empathy is NOT unique to humans: Researchers discover that rats feel the pain of others, too
Rats share some behavioral traits with humans. Now, a new Dutch study claims that the animals also empathize with others and share their pain. When a person experiences physical pain, the cingulate cortex of the brain activates in response. This region also displays activity when the person sees another individual getting hurt. Researchers at the […]

Which brain cells are active during deep sleep – and how do they affect memory formation?
There are neurons in the brain that activate during deep sleep to create memories. A new animal study showed that these brain cells might be the same as the ones responsible for investigating new objects. The experiment tracked the activity of single cells deep in the brains of both male and female mice as they […]

Flashing lights and pink noise could be the key to preventing Alzheimer’s
Researchers believe they have found a potential treatment for Alzheimer’s disease. Animal tests show that exposing mice to light flashes and sound pulses at the frequency of 40 hertz can reverse some of the symptoms of the neurodegenerative disease. Alzheimer’s disease continues to defy any attempt at treating it. Several pharmaceutical drugs help regulate a few […]

If someone calls you “bird brain” it may be a compliment: Researchers found that pigeons are better at multitasking than humans
Although pigeons have the brain of a bird, ironically, they are not exactly “bird-brained.” A recent research discovers that pigeons can multitask as fast as humans, and even faster in some situations, as reported by Science Daily. The study, published in the journal Current Biology, finds that pigeons are great in multitasking because their tiny brains […]
