Neuroscientist: "If your Ring Finger is LONGER than your Index Finger, then..." w/ Andrew Huberman

This is the challenge before people start doing this. You have to calibrate from the fold to here. It depends on the shape of the palms. The hand is a wonderful organ and one of the most complex and sensitive areas of the body made up of multiple. muscle groups from multiple joint types and innervated by three different nerves, so it is not surprising that studies are being conducted to connect the complex physiognomy of the hand with the deepest mysteries of human cognition: the complexity of the brain was First established by the father of neuroscience Santiago Ramon Icahall who discovered the nervous potential and the intricate tree-like structures of the types of nerves in the brain.

Since

then

scientists have been trying to reveal the secrets of one of the most large parts of the body whose working connections and strange effects still manage to surprise scientists today, so it is not surprising to see that

s, after years of formulating the theory of neuroplasticity, are still seeking to develop a coherent theory of how the body alters the mind. Neuroplasticity is the brain's ability to form and rewire its synaptic connections and form more complicated connections, which is especially useful after the body experiences an injury and since the brain so closely monitors and controls the functioning of the hand thanks to To the intricate and fine nature of the hand's functioning, it is not surprising that the opposite effect may be true: the human hand and its various shapes have various measurements and indices that, according to dr.

n, can determine the cognitive functions of the human mind.

Natural androgens produced in the body can affect a child's growing brain and can affect these hand indices, which can have surprisingly uniform effects that can be seen across populations on the human mind. Of course, there are multiple reasons why this may be the case, but scientists like shungatogo in a research article published in the journal Nature have discovered that the ratio of the

Complex individual variations in anatomy can also have important and interesting effects on morphology and the brain. functioning I had a project related to how androgens impact prenatal development and how they impact digit ratios in humans.

This is a study that was published in Nature in 2000 and has now been replicated no less than five times looking at the ratio of the

finger on the right hand. um it's an exposure to testosterone during prenatal development that tends to make this finger a little bit shorter than this finger in women who are more similar. Dr. Andrew Huberman, who has done decades of brain research studying sex differences in The Neuroplastic Brain explains that the structure of the human hand could actually have an effect on brain function. He theorized that in utero the effects of maternal hormones, which are natural androgens, can cause changes in the growing brain of the fetus, which in turn induces changes. in development and therefore measurable index fingers people who have been exposed to high levels of androgens may have ring fingers

Margaret Gatz and Dr Christian Pike have discovered that differences in these hand indices can actually have consequences on long-term cognition in people, so they carried out a study with a large focus group of 8,000 patients with the disease. Alzheimer's, what did they find? It turns out that women with higher 2d 40 ratios, which is the female pattern of hand development, showed more vulnerability. to develop Alzheimer's disease later in life prenatal exposure to higher levels of androgens in utero, which leads to the male pattern of hand development, and therefore having lower 2d 40 ratios tends to preserve cognition for

correlating these data with data from the assessment of cognitive functioning using three web-based cognitive tests, the number series, the vocabulary of images and verbal analogies, the human brain controls not only the physical functioning of the body but also the mental functioning, emotions and behaviors of It has been discovered that, in general, people with different handling may have different dispositions, so Embodiment is also an important aspect involved in the representation of emotions, hand posture and the intensely audiovisual processing involved in normal emotional functioning may also be contributing factors to the multitude.

Observations: People with ring fingers longer than index fingers tend to follow a more logical pattern of thinking that leads them to be excellent at problem solving, and these people tend to gravitate toward careers that require these skills, such as science or engineering. people with index fingers longer than the ring finger. Fingers tend to be lonelier and more goal-oriented. It can also indicate introversion in some cases, although that can be debated. People with the same measurement in the ring and index fingers can be quite diplomatic and can show skill and conflict. avoidance, but keep in mind, of course, that having a calm disposition doesn't mean they don't have intense personalities.

A study by Karen H James published in the journal Trends in Neuroscience Education also found that early learning to handwrite and early acquisition of the so-called reading circuit in the brain can affect the understanding and perception of letters. and improve reading skills at younger ages. This can also happen thanks to the early development of specialized processing and understanding between the two hemispheres of the brain, which can be spread by learning to write too early, hence the repeated use of regular motor functioning practice in general, but also of the hand, can cause changes that can actually be recognized in neuroimaging studies through MRI in the human brain.

The human brain is deeply interconnected with the human body from brain growth in the womb and child development to lifestyles many things. They can affect the human brain, but there are telltale signs that show up clearly in our bodies and our hands provide a surprising amount of information about how we think, feel and live our lives.
