How Fast Do We Feel Pain Study Overturns Previous Notions

Pain Management | What happens in the brain when I feel pain?

New research overturns the widespread notion that humans, unlike other mammals, process pain more slowly than touch. The findings may have significant implications for the diagnosis and treatment of pain.

Until now, the scientific consensus has been that in humans, the nerve signals that communicate touch to the brain are faster than those that relay pain.

This difference in speed, researchers believed, was due to the fact that touch signals travel through nerves with a thick coat of myelin the insulating layer of lipids that forms a protective sheath around the nerves. Myelin helps the nerves conduct signals more quickly.

In contrast, pain signals travel through nerves that either do not have myelin at all or have only a very thin layer.

Other mammals have so-called ultrafast nociceptors , that is, afferent neurons with a thick coat of myelin to convey pain signals as fast as possible. But, is the same true for humans?

Saad Nagi, a principal research engineer in the Department of Clinical and Experimental Medicine and the Center for Social and Affective Neuroscience at Linköping University in Sweden, recently led a team of researchers looking to answer this question.

The ability to feel pain is vital to our survival, explains Nagi, so why should our pain-signaling system be so much slower than the system used for touch and so much slower than it could be?

Other Factors That Influence Pain Response

While it may seem simple, the process of detecting pain is complicated by the fact that it is not a one-way system. It isnt even a two-way system. Pain is more than just cause and effect. It is affected by everything else that is going on in the nervous system. Your mood, your past experiences, and your expectations can all change the way pain is interpreted at any given time. How is that for confusing?

If you step on that rock after you have a fight with your wife, your response may be very different than it would if you had just won the lottery. Your feelings about the experience may be tainted if the last time you stepped on a rock, your foot became infected. If you stepped on a rock once before and nothing terrible happened to you, you may recover more quickly. You can see how different emotions and histories can determine your response to pain. In fact, there is a strong link between depression and chronic pain.

How We Feel Pain

Pain is a complex physiological process. A pain message is transmitted to the brain by specialized nerve cells known as nociceptors, or pain receptors . When pain receptors are stimulated by temperature, pressure or chemicals, they release neurotransmitters within the cells. Neurotransmitters are chemical messengers in the nervous system that facilitate communication between nerve cells.

As seen in the diagram, these messengers transmit a pain signal from the pain receptor to the spinal cord, and then to the thalamus, a region of the brain. The thalamus then transmits the pain signal to other areas of the brain to be processed.

Once the brain has received and interpreted the pain message, it coordinates an appropriate response. The brain can send a signal back to the spinal cord and nerves to increase or decrease the severity of pain. For example, the brain can signal the release of natural painkillers known as endorphins. Alternately, the brain can direct the release of neurotransmitters that enhance pain or hormones that stimulate the immune system to respond to an injury. Recent research has shown that people possess differing amounts of these neurotransmitters, possibly explaining why some people experience pain more intensely than others. Furthermore, recent studies have found that genetic makeup can influence an individuals sensitivity to pain.

So The Brain Can Feel Pain

The brain, among many of its functions, is in charge of interpreting the signals from our body that inform us of pain, in this way we can set in motion mechanisms that help us relieve it

However, the brain itself as an organ does not have pain receptors. This makes possible brain surgeries in which the person is awake while the neurosurgeon intervenes to remove, for example, a tumor.

This allows you to proceed with the intervention with great care, making sure that areas such as language or memory are not damaged.

Even in recent years, brain interventions have been performed while awake patients played their favorite instruments in order not to damage any nerve endings and to keep intact the functions that could be affected.

Physical And Emotional Pain Have Some Mechanisms In Common

Does the brain feel pain?

Dr. Eric Garland describes the distinct and shared mechanisms of physical and emotional pain.

Emotional pain often accompanies physical pain, but it also happens on its own. And when it does, emotional pain activates the same areas of our brain as physical pain. In fact, some studies have shown that pain relievers like acetaminophen help relive not only acute pain, but also emotional pain. So as far as our brains are concerned, our hurt feelings really do hurt.

Lobes Of The Brain And What They Control

Each brain hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions.

  • Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Brocas area, which is associated with speech ability.
  • Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships . The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernickes area, which helps the brain understand spoken language.
  • Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.
  • Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

What Is Chronic Pain And How Can It Affect People

Pain is an unpleasant sensation that can range from mild to very severe. Pain is very personal two people can have the same type and amount of pain and have very different reactions to it. Pain can affect many other parts of our lives. It can cause changes in your sleep, emotions, behavior, and even the way your body works. And it works the other way too: All of these things can make pain worse or make you more aware of it.

Pain can be either acute or chronic. Pain from an injury that is healing is considered acute pain. This kind of pain may help protect you from getting hurt again, by reminding you to be careful with the place you feel pain. Most of the time this pain goes away as you heal.

Pain is usually considered chronic when it lasts more than three months. Many people with traumatic brain injury have chronic pain at some time or other. There is typically no quick fix for chronic pain. Medicines used for acute pain often dont work well for chronic pain and may be habit-forming. Even over-the-counter pain medications like ibuprofen, aspirin, and acetaminophen might not work very well for chronic pain. If youre using any of these for more than a week or two, you should talk with your doctor. Long-term use of any medicine may be habit-forming and could damage your kidneys or liver

When Does A Fetus Feel Pain

An article from the Charlotte Lozier Institute reviews a 2019 study entitled Reconsidering Fetal Pain published in the Journal of Medical Ethics. According to the organization:

A new study Reconsidering Fetal Pain confirms that babies in the womb can feel pain as early as 12 weeks old. Writing in the Journal of Medical Ethics, Stuart W.G. Derbyshire and John C. Bockmann state: Overall, the evidence, and a balanced reading of the evidence, points towards an immediate and unreflective pain experience mediated by the developing function of the nervous system as early as 12 weeks.

Dr. David Prentice, research director and vice president of the Charlotte Lozier Institute, responded to the study, saying:

Unborn babies feel pain. The science has clearly shown for years that unborn children can perceive pain in the womb, but this is a significant admission by doctors on both sides of the abortion debate, recognizing that even early in human development, the unborn can feel pain. And as the authors note, the mere experience of pain is morally significant. Science again points to the humanity of the unborn.

Understanding How Pain Works

Does the brain feel pain? #shorts

When you drop something on your foot or slam your finger in a drawer, you know that pain will usually follow. Did you ever wonder why you feel that pain? Feeling pain in response to an injury is a signal that your body has been damaged in some way. Or, if you have an illness, headache, or other type of pain, it’s a signal to your brain that something is not right.

Our nervous system is made up of the brain and the spinal cord, which combine to form the central nervous system and our sensory and motor nerves, which form the peripheral nervous system. Nerves send information about what is happening in our environment to the brain via the spinal cord. The brain then sends information back to our nerves, helping us to perform actions in response.

Acute pain vs. chronic pain

There are two major categories of pain: acute pain or chronic pain .

With chronic pain, however, the initial pain receptors continue to fire after the injury. Chronic pain is defined as pain that lasts three months or more, or longer than expected healing time for an illness or trauma. Chronic pain can be caused by a disease or condition that continuously causes damage. For example, with arthritis, the joint is in a constant state of disrepair, causing pain signals to travel to the brain with little down time. Sometimes, there is no longer a physical cause of pain, but the pain response is the same. In these cases, it is difficult to pin down the cause of the chronic pain, and difficult to treat.

Can The Brain Repair Itself

When we suffer an injury, our skin and tissues regenerate. But the damage to the brain tends to be permanent, it has a limited regenerative capacity.

In this brief article we answered the question Does the brain feel pain? We demonstrated whether the brain is capable of feeling pain and how it processes pain from other organs of the human body.

However, social rejection from potential partners and online activity are becoming more and more commonplace. As we are now rejected frequently with small snubs like unfollowing on Twitter, swiping left on Tinder, not receiving likes on an Instagram post, not matching on a dating site or being alone during the holidays, these emotions are felt more often. Social media and constant contact to millions of people at any moment although further distances between personal connections inherently mean that more people can reject us, even if its as small as not liking our social media post when we liked theirs.

Research out of the University of Michigan suggests that not only does the brain process rejection like it does physical injury, but that personality traits such as resilience are vital to how we process pain. The brains natural painkilling response varies between humans, with some releasing more opioids during social rejection than others, meaning that some have a stronger or more adaptive – protective ability.

When mu opioid is released, there is a trigger in two areas of the brain, one processes the strength of the emotion, and the other determines how your mood changes because of the event. Therefore, the more opioid released, the greater reduction in pain – and possibly a greater experience of pleasure when someone feels that theyve been socially accepted or validated.

What The Nervous System Does

Your nervous system is made up of two main parts: the brain and the spinal cord, which combine to form the central nervous system and the sensory and motor nerves, which form the peripheral nervous system. The names make it easy to picture: the brain and spinal cord are the hubs, while the sensory and motor nerves stretch out to provide access to all areas of the body.

Put simply, sensory nerves send impulses about what is happening in our environment to the brain via the spinal cord. The brain sends information back to the motor nerves, which help us perform actions. Its like having a very complicated inbox and outbox for everything.

Can the Brain Itself Feel Pain? ... No There are no pain ...

So the researchers monitored the brain waves of a dozen people who were asked to pay attention only to their hand or only to their foot. During the experiment the scientists delivered a light tap to each person’s finger or toe.

When participants focused on their feet, low-frequency rhythms increased in the brain area that responds to hand sensations because participants were asking their brains to ignore sensory input from the hand, and it’s these low-frequency rhythms that do the blocking of such information. That was expected.

But low-frequency rhythms also increased in a different brain area the region that ignores distractions, the team discovered. They reported their findings in the current issue of The Journal of Neuroscience.

The two areas became synchronized, Jones says. “There’s coordination between the front part of the brain, which is the executive control region of the brain, and the sensory part of the brain, which is filtering information from the environment,” she says.

That suggests that at least some people can teach their brains how to filter out things like chronic pain, perhaps through meditation, Jones says.

A 2011 study supports this idea. It found that people who practiced mindfulness meditation for eight weeks greatly improved their control of the brain rhythms that block out pain.

The Brain Doesn’t Feel Pain

03 March, 2020

The brain is the organ responsible for processing pain, integrating the incoming information through nerve terminals, and the interpretation of these signals. However, interestingly, the organ itself doesnt feel pain.

Thus, pain is a vital signal that warns of an injury or damage. And it sets natural mechanisms in motion to solve it. The way it does it is through a series of nerve endings that pick up a signal.

The name of these endings is nociceptors and they receive sensory information from the outside and inside of your bodies. Theyre at the end of the axons of sensory neurons and can transmit it to the brain. Also, it can transmit information about mechanical, thermal, or chemical lesions in a matter of tenths of a second to the entire nervous system.

When To Consult With Your Doctor

Because the brain doesnt feel pain, headaches are the main symptom that signals injuries to this organ. But not all headaches indicate something serious, as indicated above.

You must know when this pain may be due to truly serious causes so you can consult a doctor. Thus, medical attention is necessary when:

  • The pain interferes with your daily life.
  • Its stronger after physical activity.
  • Its associated with vision, mobility, language, or memory alterations.
  • Is it worse in 24 hours?
  • It manifests with other symptoms such as fever, stiffness, and nausea.
  • Theres redness in one eye.
  • You have a history of cancer or a weakened immune system.
