A team of scientists in Basel believes this will open up new lines of research.
- Switzerland-based researchers successfully used Neanderthal DNA to grow a brain organoid.
- The team, led by Grayson Camp, used induced pluripotent stem cells, which are used to research diabetes, leukemia, and neurological disorders.
- By tracing back our ancestral lineage, the team hopes to better understand genetic disease susceptibility.

He successfully extracted and sequenced Neanderthal DNA, opening up an entirely new field of genetic research. Evolving on that work, a team lead by <a href="https://www.graycamplab.org/" target="_blank">Grayson Camp</a> at the Institute of Molecular and Clinical Opthalmology in Basel, Switzerland has grown Neanderthal DNA-containing brain tissue for the first time.</p><p>The team used induced pluripotent stem cells (iPSC), which are normally derived from human skin or blood cells. Stem cells are biological gold. By reprogramming these cells back to an embryonic-like state, researchers can develop a wide range of human cells for therapeutic purposes. This is exactly what Camp hopes this research on the Neanderthal genome will help accomplish. </p><p>Genetic codes reveal secrets around biological development and susceptibility to disease. Since stem cells can resemble brain, stomach, skin, kidney, and intestinal (among others) human tissues, their range of utility is endless. Researchers are hopeful that stem cells will help combat the ravages of diabetes, leukemia, and neurological disorders, among numerous other diseases. </p><p>As the team writes, Neanderthal DNA provides a wealth of genetic resources, including "skin and hair color, immune response, lipid metabolism, skull shape, bone morphology, blood coagulation, sleep patterns, and mood disorders." </p>

Alleles (gene variants) were identified for digestive function, immune response, and skin color. Camp believes this research is beneficial for studying human developmental processes.</p><p>After identifying Neanderthal genes, the team grew brain organoids, 3D blobs of brain tissue barely a few millimeters in size. Organoids are diverse resources in laboratory settings, especially in drug treatment research. Cancer treatment protocols are often tested on these blobs, for example. </p><p>While his team's work is exciting, Camp <a href="https://www.cnn.com/2020/06/18/world/brain-organoids-neanderthal-dna-scn-trnd/index.html" target="_blank">warns</a> that this is no science fiction experiment. </p><p style="margin-left: 20px;">"These are human cells, they're not Neanderthal cells but human cells that have Neanderthal DNA naturally inside them. This is totally different to Jurassic Park.<strong> </strong>It's more about studying the mechanism than try to recreate something." </p><p>While these culture systems are not yet optimal, the process has begun. Camp is interested in studying other <em>Homo</em> ancestors, such as Denisovan DNA. The further we dial back the clock, the better we understand our origins. If that path leads to treatments or cures for some of humanity's most prolific killers, the backpedaling will be worth it. </p><p><span></span>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Along the way, there have been many pioneers in the feild of hypnosis research.
Photo by Brian A Jackson on Shutterstock<p>The "modern father" of hypnosis was Austrian physician Franz Mesmer, who gave us the word "mesmerism", which can be another word referencing a hypnotic state. Mesmer had an idea for which he called "animal magnetism" - and the idea was that there are these kinds of natural energy sources that could be transferred between organisms and objects.</p><p>Along the way, hypnotism has had many other pioneers who have furthered the fascinating phenomenon. One of the most notable is James Braid, an eye doctor based in Scotland who became intrigued with the idea of hypnosis when he discovered a patient in his waiting room had fallen under something of a trance after staring at a lamp. He gave the patient come commands, and the patient obliged, remaining in a trace-like state the entire time. </p><p>Braid's fascination grew and through more tests, he determined that getting a patient to fixate on something was one of the most important components to hypnosis. He later would publish a book on what we now know as the <a href="https://books.google.be/books/about/The_Discovery_of_Hypnosis.html?id=Vs35STwQYQoC&redir_esc=y" target="_blank">discovery of modern hypnosis</a>.</p><p>Later, James Esdaile, a British surgeon based in India during the mid-1800s established that this kind of trance hypnotic state was extremely useful in pain relief practices. He performed hundreds of major operations using hypnotism as his only anesthetic. When he returned to England in an attempt to convince the medical establishments of his findings, they paid no mind to his theory in favor of new chemical anesthetics such as morphine, which was <a href="https://www.drugfreeworld.org/drugfacts/painkillers/a-short-history.html" target="_blank">relatively new at the time</a>. This is where the use of hypnotics for medicinal purposes halted and much of the reason why hypnosis is considered an alternative approach to medicine in today's society.</p><p>Jumping forward to the 1900s, Frenchman Emile Coué moved away from the conventional approaches that had been pioneered with hypnotism and began his work with the use of auto-suggestion. </p><p>He is most famous for the phrase: <em>"Day by day, in every way, I am getting better and better." </em>This technique was one of the first instances where affirmation hypnosis was used and it has been growing through various counseling programs and therapy techniques ever since.</p><p>In modern times, one of the most recognized authorities on clinical hypnosis remains to be Milton Erikson, a well-known psychotherapist who did most of his work around 1950-1980. He was fascinated with human psychology and devised countless innovative ways to use hypnosis in his clinical practices. </p>
Scientists scanned the brains of 57 people during a guided hypnosis session.

According to a 2016 Stanford University School of Medicine study, there are three areas of our brains that change during a state of hypnosis - and this could actually be used to benefit us.</p><p>Scientists scanned the brains of 57 people during a guided hypnosis session, similar to one that may be used to help treat anxiety, pain, or trauma. </p><p><strong>First, there is a decrease in dorsal anterior cingulate activity. </strong></p><p>This is part of the brain's salience network that is responsible for <a href="https://www.alleydog.com/glossary/definition.php?term=Anterior+Cingulate+Cortex" target="_blank">psychological functions</a> like decision making, evaluation processes, and emotional regulation as well as physiological functions such as blood pressure and heart rate. </p><p><strong>Next, there is an increase in the connection between the dorsolateral prefrontal cortex and the insula. </strong></p><p>The <a href="https://www.sciencedirect.com/topics/neuroscience/dorsolateral-prefrontal-cortex" target="_blank">dorsolateral prefrontal cortex</a> is associated with executive functions such as working memory and self-control. The <a href="https://www.spinalcord.com/insular-cortex" target="_blank">insula</a> is a small region of the cerebral cortex that plays a significant role in pain perception, social engagements, emotions, and autonomic control. </p><p>This is described by the lead researcher of the study as a kind of "brain-body connection" that helps the brain process and control what's going on in the body. </p><p><strong>Finally, there are reduced connections between the dorsolateral prefrontal cortex and the medial prefrontal cortex. </strong></p><p>The dorsolateral prefrontal cortex becomes less connected to the medial prefrontal cortex and the <a href="https://www.jneurosci.org/content/32/1/215" target="_blank">posterior cingulate cortex</a>, both of which are strongly associated with neural activity and cognitive tasks.</p><p>This decrease very likely correlates to the disconnect between someone's actions and their awareness of their actions, according to the lead researcher on the project. </p><p><strong>How does this change the way we view hypnosis?</strong></p><p>Understanding exactly which areas of the brain are impacted during hypnosis can pave the way for groundbreaking research into the use of hypnosis for medicinal purposes.</p><p>"Now that we know which brain regions are involved," says David Spiegel, MD, professor and researcher on the project, "we may be able to use this knowledge to alter someone's capacity to be hypnotized or the effectiveness of the hypnosis for problems such as pain control." </p><p>While more research is needed, the study is certainly a groundbreaking head-start in what could eventually be known as hypnotic treatments for things like anxiety, trauma and pain management. </p><p>"A treatment that combines brain stimulation with hypnosis could improve known analgesic effects of hypnosis and potentially even replace addictive and side-effect-laden painkillers and anti-anxiety medications," explains Spiegel. </p>
A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.
- A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
- The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
- The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.

One of the highlights of this study was exploring the differences sexual activity has in cognitive function in older males and older females.
Photo by Gligatron on Shutterstock<p>Exploring the differences when it comes to the improved cognitive ability between the older males and the older females in this study was one of the highlights of the research.</p><p><strong>Testosterone versus oxytocin</strong></p><p>Testosterone, which is the male sex hormone, reacts very differently to the brain than oxytocin, which is released in females during sexual activity. </p><p><a href="https://www.healthline.com/health/benefits-testosterone" target="_blank">Testosterone</a> plays a key role in many different areas such as muscle mass, facial and pubic hair development, and mood changes. It also impacts your sex drive and your verbal memory and thinking ability. </p><p>Testosterone belongs to a class of male hormones, and although the ovaries of a woman do produce <a href="https://www.webmd.com/women/guide/normal-testosterone-and-estrogen-levels-in-women#1" target="_blank">minimal amounts of testosterone</a>, it's not enough to compare the impacts on the male and female bodies.</p><p><a href="https://www.healthline.com/health/love-hormone#biologicalsex-and-oxytocin" target="_blank">Oxytocin</a>, on the other hand, is produced in the male and female bodies <a href="https://pubmed.ncbi.nlm.nih.gov/9361803/" target="_blank">quite similarly</a>, but ultimately the hormone reacts differently in the female body, triggering the portion of the brain responsible for emotion, motivation, and reward. </p><p>These differences in testosterone and oxytocin may factor into why the male cognitive level changes much more during sexual activity in older age. </p><p><strong>Women's ability for memory recall remains a mystery…</strong></p><p>Another study, this time <a href="https://pubmed.ncbi.nlm.nih.gov/9421566/" target="_blank">back in 1997</a>, looked at the relationship between gender and episodic memory. The results of this study proved that women have a higher level of performance on episodic memory tasks (for example, <a href="https://pubmed.ncbi.nlm.nih.gov/10101879/" target="_blank">recalling childhood memories</a>) than men. The reason for this was not further explored in this study and has remained something of a mystery, even now. </p><p><strong>The female brain deteriorates during menopause.</strong></p><p>Women very commonly struggle with memory-related problems during and post-menopause. This could be the reason why the original study proved older men had a higher cognitive ability in number sequencing than older women. </p><p>Along with menopause-related cognitive decline, women are also at a <a href="https://www.sciencedaily.com/releases/2016/11/161109112447.htm" target="_blank">higher risk for memory impairment</a> and dementia compared to men. </p><p>Lead researcher of the original 2016 study, Dr. Hayley Wright, from Coventry University, explains:</p><p><em>"Every time we do another piece of research we are getting a little bit closer to understanding why this association exists at all, what the underlying mechanisms are and whether there is a 'cause and effect' relationship between sexual activity and cognitive function in older people." </em></p>
