    The newest neuron has been named the "rosehip neuron," thanks to its bushy appearance. The brain cell, with its unique genes, distinctive shape and diverse connections with other neurons, has not been described before and, what's more, it isn't present in neuroscientists' favorite subject: mice.... Also adding to the rosehip appearance are the large bulbs at the end of their axons that release neurotransmitters or chemical signals to other neurons, Bakken added. … One reason rosehip neurons eluded neuroscientists for so long is likely because the cells are so rare in the brain, Bakken said. Another reason, he added, is...

    The family of longtime Sen. John McCain, R-Ariz, said Friday that he has chosen to discontinue medical treatment for brain cancer. "Last summer, Senator John McCain shared with Americans the news our family already knew: he had been diagnosed with an aggressive glioblastoma, and the prognosis was serious. In the year since, John has surpassed expectations for his survival. But the progress of disease and the inexorable advance of age render their verdict. With his usual strength of will, he has now chosen to discontinue medical treatment. Our family is immensely grateful for the support and kindness of all his...

  • Smoking cannabis ages the brain by an average of 2.8 YEARS

    Smoking cannabis ages the brain by an average of 2.8 years, new research suggests. This is compared to four years in schizophrenia patients, according to the largest study of its kind. Brain ageing is defined as reduced blood flow through the organ. Excessive alcohol also ages the organ by 0.6 years, the research adds. Lead author Dr Daniel Amen, founder of Amen Clinics, said: 'The cannabis abuse finding was especially important, as our culture is starting to see marijuana as an innocuous substance. This study should give us pause about it.' Reduced brain blood flow has previously been linked to...

    What is the core function of a healthy adaptive brain? This researcher says its function is not merely to sort the input of our senses, but to create predictive models based on the cumulative weight of that input. This hypothesis strikes me as rather obvious and thus not entirely insightful. Though that’s plainly not an opinion shared by many, who believe an orderly brain is one that disregards its own predicted models in favor of those espoused by the Huffington Post. Here’s how the article described the function of this seemingly tertiary organ. The main purpose of the brain, as...

    The brain is a soft mass of supporting tissues and nerves connected to the spinal cord. Some nerves in the brain go straight to the eyes, ears and other parts of the head. Other nerves connect the brain to other parts of the body through the spinal cord to control the personality, senses, and functions of the body from breathing to walking.Read more

    An analysis of students in the US has found that those who have a certain type of brain parasite are more likely to be majoring in business studies. Toxoplasma gondii is a protozoan parasite carried by cats. It can infect people through contact with cat faeces, poorly cooked meat, or contaminated water, and as many as one-third of the world’s population may be infected. The parasite doesn’t make us feel sick, but it forms cysts in the brain where it can remain for the rest of a person’s life. Some studies have linked infection with the parasite to slower reaction...

    Child Prodigies Disprove Brain Size as Intelligence Driver July 24, 2018 | David F. Coppedge It’s not the size; it’s the wiring. Don’t we know that for electronics? Why are evolutionists still obsessed with brain size? Measuring skull capacity as a proxy for intelligence has a long history. In his book The Mismeasure of Man (1981), Stephen Jay Gould recounted how Victorian evolutionists were obsessed with skull measurements (craniometry) in their determination to prove Europeans were superior to other races. As he shows, their a priori bias influenced what they “saw” in their measurements as they preferred only the measurements...

    BOSTON, Mass. (CBS Local) – With many states dealing with record-high temperatures and massive heat waves, many people are probably sick of summer already. A new study says that your brain may hate the heat more than you do. Researchers at Harvard University have discovered that a person’s brain works 13 percent slower when it has to operate in extreme heat. According to their report in PLOS Medicine, scientists studied 44 college students living in Boston during a 2016 heat wave. That July heat wave was reportedly one of the hottest in the city’s history. 22 of the students lived...

    Canadians will soon be able to order marijuana through the mail as part of the nation’s new legalization of recreational pot. Lawmakers in the country passed the Cannabis Act earlier this week, setting the country up to regulate the market in the coming months. Prime Minister Justin Trudeau announced Wednesday that legalization will begin on Oct. 17. The country is the second to legalize the substance nationwide, after Uruguay. The federal minimum age for marijuana use in Canada will be 18, but some provinces are setting their own minimum age at 19, which is the drinking age in most areas....

    Last year, my husband and I purchased our first house. Lucky for us new homeowners, the house needed minimal work. [snip] Last month, in the middle of the night, I woke up startled. It felt like someone had placed a chip of ice in my left earhole—but it was something way worse. I shot up out of bed, disoriented, and stumbled to the bathroom. I could feel that my ear was not right. I grabbed a cotton swab and gently inserted it into my ear to see what was up and I felt something move. When I pulled the cotton...

    One of the things I fuss about a lot (especially at Buffer) are words—very simple words, in fact. Should it say “Hi” or “Hey?” Should it be “cheers” or “thanks?” How about “but” or “and?” There are many occasions when Joel and I sit over one line and change it multiple times, until we feel it really sits right. This is partly to improve our metrics for click rate and others. It is also to simply create the right emotion. The one key question we ask ourselves is: “How does this make you feel?” The question might sound very...

    (CNN)Marijuana is notorious for slowing certain cognitive functions such as learning, memory and attention span (maybe that's why they call it "dope"?). But new research in young people suggests that these cognitive effects, while significant, may not persist for very long, even among chronic users. The meta-analysis, published Wednesday in the journal JAMA Psychiatry, combines data from 69 previous studies that look at the effects of heavy cannabis use on cognitive functioning in adolescents and young adults. It found that those young people who identified as heavy marijuana users scored significantly lower than non-users in a variety of cognitive domains...

    President Trump earned a perfect score on a medical test that is used to detect early signs of dementia or Alzheimer's disease. The test, called the Montreal Cognitive Assessment, was conducted during his routine physical on Friday, at the insistence of the president, who wanted to tamp down rumors about his mental abilities that have surfaced from his critics. Dr. Ronny Jackson, the White House doctor who conducted the exam, said that he did not believe it was necessary because he hadn't noticed any issues with Trump's memory after spending the past year with him. The doctor's quarters are in...

    An international team of scientists have confirmed the discovery of a major cause of dementia, with important implications for possible treatment and diagnosis. Professor Garth Cooper from The University of Manchester, who leads the Manchester team, says the build-up of urea in the brain to toxic levels can cause brain damage - and eventually dementia. The work follows on from Professor Cooper's earlier studies, which identified metabolic linkages between Huntington's, other neurodegenerative diseases and type-2 diabetes. The team consists of scientists from The University of Manchester, the University of Auckland, AgResearch New Zealand, the South Australian Research and Development Institute,...
