Oldest brain in a backboned animal found in fish fossil

Posted by in categories: biotech/medical, neuroscience

Very old brain, some ancient philosophy maybe…


A fossilised fish originally dug up more than a century ago in an English coal mine has been shown to hold the world’s oldest brain in a vertebrate animal.

CT scans revealed the new internal features including a brain and cranial nerves about 2 centimetres long.

‘Time is not what it used to be’: Children and adults shown to experience time differently

Posted by in category: neuroscience

Researchers at Eötvös Loránd University have investigated whether the perception of time changes with age, and if so, how, and why we perceive the passage of time differently. Their study was published in Scientific Reports.

Time can play tricks on us. Many of us experienced the illusion that those long summers during childhood felt so much longer than the same 3 months feel like now as an adult. While we can argue why one summer may appear longer than the other and how the perception of time can compress and dilate durations depending on various factors, we can easily set up an experiment to gain more insights.

The researchers just did that. They asked how eventfulness affects our duration estimates when probing at different milestones during our cognitive development. They set aside three , 4–5, 9–10, and 18 years and older, and made them watch two videos, 1 minute each. The two videos were extracted from a popular animated series, balanced in visual and acoustic features, except for one feature: eventfulness.

The Brain Works Like a Resonance Chamber

Posted by in category: neuroscience

Summary: Using advanced neuroimaging techniques, researchers discovered distant brain regions oscillate together in time.

It’s been over 20 years since neuroimaging studies – using functional magnetic resonance imaging (fMRI), a widely-used technology to capture live videos of brain activity – have been detecting brain-wide complex patterns of correlated brain activity that appear disrupted in a wide range of neurological and psychiatric disorders.

Prolific autism researcher has two dozen papers retracted

An autism researcher lost two dozen papers to retraction in January, eight years after the publisher was made aware of potentially troubling editorial practices. Elsevier, the publisher, cited undisclosed conflicts of interest, duplicated methodology and a “compromised” peer-review process as reasons for the retractions.

The papers were published in Research in Developmental Disabilities and Research in Autism Spectrum Disorders between 2013 and 2014 — a period when Johnny Matson, then professor of psychology at Louisiana State University (LSU) in Baton Rouge and an author on all of the papers, was editor-in-chief of both journals.

Will Revitalizing Old Blood Slow Aging?

Posted by in categories: biotech/medical, life extension, neuroscience

Rejuvenating an older person’s blood may now be within reach, based on recent findings from Passegué’s lab published in Nature Cell Biology(link is external and opens in a new window).

Passegué, with her graduate student Carl Mitchell, found that an anti-inflammatory drug, already approved for use in rheumatoid arthritis, can turn back time in mice and reverse some of the effects of age on the hematopoietic system.

Depression and Anxiety Exhaust the Heart, Literally

Posted by in categories: biotech/medical, neuroscience

A 1967 publication titled “Mortality of Bereavement” discovered that bereaved relatives had a 7-fold increased risk of dying within the following year. Despite that the cause of death was undetermined, this is the first scientific evidence indicating that extreme sadness kills.

Coined in 1991, Takotsubo cardiomyopathy — or broken heart syndrome — mimic aspects of a heart attack such as shortness of breath, fainting, and chest pain. But, oddly, they have no blocked arteries. Instead, some parts of the heart stopped moving and other heart muscles try to compensate for this. This turns the heart into an irregular shape, like that of an octopus pot — hence, the name “Takotsubo” (‘Tako’ means octopus and ‘tsubo’ means pot in Japanese). This condition is reversible but can be fatal at times. Takotsubo cardiomyopathy is triggered by intense emotions or stressful life events such as the death of a loved one and losing (or even winning) a lot of money. This is why “heartbroken” from sadness is a legitimate phenomenon.

Research advances further confirm that sadness, or more accurately emotional stress, destroy the heart in many ways. The mind-heart connection extends to far more than just the broken heart syndrome. Convincing epidemiological evidence ascertains that emotional pains can lead to heart diseases, the major killer worldwide, and this linkage is underpinned by biology.

Blobs of human brain planted in rats offer new treatment hope

Posted by in categories: biotech/medical, neuroscience

The team behind the work suggest that eventually doctors might be able to grow blobs of brain tissue from a patient’s own cells in the lab and use them to repair brain injuries caused by stroke or trauma.

“This is incredibly exciting to me as a physician,” said Isaac Chen, a physician and assistant professor of neurosurgery at the University of Pennsylvania.

The study is the latest in the rapidly growing and ethically complex field of brain organoids. Scientists have shown that when cultivated in the right conditions, neurons begin to form tiny brain-like structures, allowing scientists to investigate developmental conditions such as autism and a wide range of basic neuroscience questions.

Goodbye coffee, hello brain stimulation? People are zapping their brains at home to clear brain fog

In 2021, Craig Gibbons was diagnosed with Lyme disease. His doctor prescribed him antibiotics, but the medication failed to eliminate one of his most debilitating symptoms: a lasting brain fog that made it difficult for him to focus or recall information.

So he went with a different approach: at-home brain stimulation.
