What Are The 4 Lobes Of The Brain

How Different Parts of Your Brain Control Your Breathing

The cerebrum’s left and right hemispheres are each divided into four lobes: the frontal, parietal, occipital and temporal lobes. The lobes generally handle different functions, but much like the hemispheres, the lobes don’t function alone. The lobes are separated from each other by depressions in the cortex known as sulcus and are protected by the skull with bones named after their corresponding lobes.

The frontal lobe is located in the front of the brain, running from your forehead to your ears. It is responsible for problem-solving and planning, thought, behavior, speech, memory and movement. The frontal lobe is separated from the parietal lobe by the central sulcus and is protected by a singular frontal skull bone.

The parietal lobe picks up where the frontal lobe ends and goes until the mid-back part of the brain . It is responsible for processing information from the senses , as well as language interpretation and spatial perception. It is separated from the other lobes on all four sides: from the frontal lobe by central sulcus from the opposite hemisphere by the longitudinal fissure from the occipital lobe by parieto-occipital sulcus and from the temporal lobe below by a depression known as the lateral sulcus, or lateral fissure. Because each hemisphere has a parietal lobe, there are two parietal skull bonesone on the external side of each hemisphere.

Your Breath Is Your Brains Remote Control

A study has found evidence to show that there is actually a direct link between nasal breathing and our cognitive functions.

We have all heard this simple saying during times of trouble: Take a deep breath in. Science being science, however, indicates that we may now have to update this old adage to read Take a deep breath in it will help you be more emotionally aware but only if you inhale specifically through your nostrils and not your mouthgood luck.

While this may seem a lengthy tip to recall in the midst of uh-oh moments, the power of active breathingvoluntarily inhaling and exhaling to control our breathing rhythmhas been known and used throughout history. Even today, in tactical situations by soldiers, or in extreme cold conditions by the Ice Man, we know that slow, deep breathing can calm the nervous system by reducing our heart rate and activating the parasympathetic nervous system. In this way, our bodies become calm, and our minds also quieten. Recently, however, a new study has found evidence to show that there is actually a direct link between nasal breathing and our cognitive functions.

About Brain Stem Death

Brain stem death is when a person no longer has any brain stem functions, and has permanently lost the potential for consciousness and the capacity to breathe.

When this happens, a ventilator keeps the person’s heart beating and oxygen circulating through their bloodstream.

A person is confirmed as being dead when their brain stem function is permanently lost.

Why Heroin Causes Pleasure & Pain Relief

Human Brain: facts and information

When the body feels pleasure, such as when you hug a loved one, a small amount of endorphins attach to the brains opioid receptors. But heroin overwhelms the receptors, causing a large surge in happiness. Thats why many people say using heroin feels like extreme happiness or relaxation.

Opioid receptors affect more than happiness. Heroin can temporarily relieve feelings of depression or anxiety. The drug can also relieve pain the same way that prescription opioids relieve pain. High doses of opioids attach to opioid receptors, which prevents the brain from making you feel any type of pain.

The immediate positives associated with heroin arent worth the risks. Opioid receptors control important life functions, and heroin disrupts these processes. When the brain is flooded with heroin, opioid receptors in the brain can no longer tell the body how to function properly.

The brain and spine are vital to keep the body alive and functioning. Everything we do depends on the messages that are sent from the brain, along the spinal cord and on to the rest of the body.

The Cerebellum’s Left And Right Hemispheres

The cerebellum also has two hemispheres: the left cerebellar hemisphere and the right cerebellar hemisphere. Just as the longitudinal fissure divides the cerebrum’s hemispheres, the “vermis” separates the cerebellum’s hemispheres.

Sighing Sniffing And Deep Breathing

The first group of neurons he found were the ones that control sighing. A sigh is essentially a double breath that allows the lungs to fully inflate. This is physiologically important because the many minute alveoli of the lungs begin to collapse in the course of normal breathing and must be reinflated through sighing.

In fact, all mammals sigh, and the smaller the animal, the more frequent the sighing because tinier alveoli are more prone to collapse. We hardly notice it, but humans spontaneously sigh about every five minutes. Mice sigh every two minutes.

Through his genetic screening, Yackle found some cells near the preBötC that were producing an interesting molecule. Earlier work by Feldmans lab at UCLA had found that a similar molecule called bombesin could induce sighing when injected into the brain stem. Realizing they held different pieces of the same puzzle, the two labs worked together to identify the preBötC neurons responsible for sighing. When these neurons are disabled, mice do not sigh.

Since then, Yackle has also identified neurons in the preBötC that act as a relay station between breathing and a brain area involved in attention and arousal. Sniffing in mice normally triggers alertness, but with these neurons disabled, the feedback system is broken and mice are uncharacteristically calm instead of anxiously exploring a new environment, they settle down to groom.

    What Part Of The Brain Controls Fear

    From a biological standpoint, fear is a very important emotion. It helps you respond appropriately to threatening situations that could harm you.

    This response is generated by stimulation of the amygdala, followed by the hypothalamus. This is why some people with brain damage affecting their amygdala dont always respond appropriately to dangerous scenarios.

    When the amygdala stimulates the hypothalamus, it initiates the fight-or-flight response. The hypothalamus sends signals to the adrenal glands to produce hormones, such as adrenaline and cortisol.

    As these hormones enter the bloodstream, you might notice some physical changes, such as an increase in:

    • heart rate
    • blood sugar
    • perspiration

    In addition to initiating the fight-or-flight response, the amygdala also plays a role in fear learning. This refers to the process by which you develop an association between certain situations and feelings of fear.

    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.

    Breathing And Your Brain: Five Reasons To Grab The Controls

      The advice to just breathe when youre stressed may be a cliché of Godzilla-sized proportions, but that doesn’t make it untrue. The substance behind the saying is research-testedand not only to manage stress.

      Breathing is an unusual bodily function in that it is both involuntary and voluntary. Other major functionstake digestion and blood flow, for exampleoccur without conscious influence, and for the most part we couldnt influence them if we tried. They are involuntarily managed in the vast processing system of the unconscious mind.

      Breathing is also managed in the unconscious, but at any moment we can grab the controls and consciously change how we breathe. We can make our breathing shallow or deep, fast or slow, or we can choose to stop breathing altogether .

      Since we are breathing all the time, the oddness of this dual-control system doesnt usually dawn on usbut its this control flexibility that makes breathing especially worthy of attention. We can change how we breathe, and to an extent change how breathing affects our bodies.

      Controlled breathing, also known as paced respiration, diaphragmatic breathing and deep breathing, has long been a feature of Eastern health practices. It became more visible in the West after Dr. Herbert Bensons book, The Relaxation Response, hit shelves in the mid 1970s. Whatever you choose to call controlled breathing, the dynamic at work is full oxygen exchange: more oxygen enters the body and more carbon dioxide exits.

      What Part Of The Brain Controls Happiness

      Brain Bibbers â The science behind anxiety â theGIST

      Happiness refers to an overall state of well-being or satisfaction. When you feel happy, you generally have positive thoughts and feelings.

      Imaging studies suggest that the happiness response originates partly in the limbic cortex. Another area called the precuneus also plays a role. The precuneus is involved in retrieving memories, maintaining your sense of self, and focusing your attention as you move about your environment.

      A 2015 study found that people with larger gray matter volume in their right precuneus reported being happier. Experts think the precuneus processes certain information and converts it into feelings of happiness. For example, imagine youve spent a wonderful night out with someone you care about. Going forward, when you recall this experience and others like it, you may experience a feeling of happiness.

      It may sound strange, but the beginnings of romantic love are associated with the stress response triggered by your hypothalamus. It makes more sense when you think about the nervous excitement or anxiety you feel while falling for someone.

      As these feelings grow, the hypothalamus triggers release of other hormones, such as dopamine, oxytocin, and vasopressin.

      Dopamine is associated with your bodys reward system. This helps make love a desirable feeling.

      Vasopressin is similarly produced in your hypothalamus and released by your pituitary gland. Its also involved in social bonding with a partner.

      Can You Recover From A Brainstem Injury

      A brainstem injury can have severe effects because the brainstem controls so many of your bodys most basic functions. But people do recover from some types of brainstem injuries.

      Its important to get care right away if you suspect a brainstem injury. The sooner you get care, the more likely your healthcare providers can reduce the damage. You may need rehabilitation and other special care after a brainstem injury.

      Searching For The Brain Cells That Control Our Breathing

        We take roughly 20,000 breaths a day, mostly without thinking, but exactly how our breathing is controlled is a puzzle that has perplexed thinkers from Aristotle to Galen to modern physiologists.

        This universal mammalian instinct is still so poorly understood that there currently are no pharmacological treatments for human breathing disorders, like sleep apnea or sudden infant death syndrome.

        Just as our heartbeat is controlled by pacemaker cells in the heart, our breathing is regulated by a cluster of a few thousand cells in the brainstem known as the preBötzinger Complex, or preBötC. Discovered in 1991, these cells are the center of breathing regulation. They send rhythmic signals to our spinal cord, which relays them to skeletal muscles, like the diaphragm, that expand our lungs.

        But the mechanisms by which this region of the brain regulates breathing are still a mystery, one that UC San Francisco physiologist Kevin Yackle, MD, PhD, is tackling with the latest tools of molecular biology.

        Yackle, a Sandler Faculty Fellow, is trying to zero in on the specific cells of the preBötC that generate the breathing rhythm though not all researchers in the field agree if such a breathing pacemaker exists.

        How Much Sleep Do You Need

        Your need for sleep and your sleep patterns change as you age, but this varies significantly across individuals of the same age. There is no magic number of sleep hours that works for everybody of the same age. Babies initially sleep as much as 16 to 18 hours per day, which may boost growth and development . School-age children and teens on average need about 9.5 hours of sleep per night. Most adults need 7-9 hours of sleep a night, but after age 60, nighttime sleep tends to be shorter, lighter, and interrupted by multiple awakenings. Elderly people are also more likely to take medications that interfere with sleep.

        In general, people are getting less sleep than they need due to longer work hours and the availability of round-the-clock entertainment and other activities.

        Many people feel they can catch up on missed sleep during the weekend but, depending on how sleep-deprived they are, sleeping longer on the weekends may not be adequate.

        An understanding of exactly how the brain controls breathing is fundamental to the treatment of respiratory disorders. We know that breathing is an automatic rhythmic process that persists without conscious effort whether we are awake or asleep, but the question that has intrigued many scientists for well over 100 years is what maintains this almost fail safe vital rhythm throughout life?

        A Sorting Station: The Thalamus Mediates Sensory Data And Relays Signals To The Conscious Brain

        The diencephalon is a region of the forebrain, connected to both the midbrain and the cerebrum. The thalamus forms most of the diencephalon. It consists of two symmetrical egg-shaped masses, with neurons that radiate out through the cerebral cortex. Sensory data floods into the thalamus from the brain stem, along with emotional, visceral, and other information from different areas of the brain. The thalamus relays these messages to the appropriate areas of the cerebral cortex. It determines which signals require conscious awareness, and which should be available for learning and memory.

        What Are The Main Parts Of The Brain

        There are three main parts of the brain: the cerebrum, cerebellum and the brain stem.

        The cerebrum is the largest part of the brain. Located in the front and middle part of the brain, it accounts for 85% of the brain’s weight. Of the three main parts of the brain, the cerebrum is considered the most recent to develop in human evolution. The cerebrum is responsible for all voluntary actions , communication, emotions, creativity, intelligence and personality.
