Brain Lobes and Left and Right Hemispheres of the Brain
  • Do you think that animals experience emotion? What aspects of brain structure might lead you to believe that they do or do not?
  • Consider your own experiences and speculate on which parts of your brain might be particularly well developed as a result of these experiences.
  • Which brain hemisphere are you likely to be using when you search for a fork in the silverware drawer? Which brain hemisphere are you most likely to be using when you struggle to remember the name of an old friend?
  • Do you think that encouraging left-handed children to use their right hands is a good idea? Why or why not?
  • Brain Areas And Their Functions

    The brain is divided into areas which are each responsible for different areas of functioning.

    The brain can be divided into three basic units: the forebrain, the midbrain and the hindbrain.

    These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe.Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain.

    The image below indicates where the areas are.

    Occipital lobe: This is found in the back of the brain. The area is involved with the brain’s ability to recognise objects. It is responsible for our vision.

    Temporal lobe: The temporal lobes are found on either side of the brain and just above the ears. The temporal lobes are responsible for hearing, memory, meaning, and language. They also play a role in emotion and learning. The temporal lobes are concerned with interpreting and processing auditory stimuli.

    Parietal lobe: The parietal lobes are found behind the frontal lobes, above the temporal lobes, and at the top back of the brain. They are connected with the processing of nerve impulses related to the senses, such as touch, pain, taste, pressure, and temperature. They also have language functions.

    Frontal lobe:It is concerned with emotions, reasoning, planning, movement, and parts of speech. It is also involved in purposeful acts such as creativity, judgment, and problem solving, and planning

    Do Different Brain Regions Control Different Functions

    Doctors originally divided the brain into four separate regions for the sake of conveniently labeling anatomical functions. We now know that the lobes of the brain roughly correlate with a variety of functions. The temporal lobe, for instance, plays a key role in auditory processing, while the frontal lobe helps regulate attention and memory.

    This doesn’t mean that brain regions control these functions. Many functions overlap across brain regions, and the functioning of one region often depends on another. Moreover, some research suggests that when there is damage to one region of the brain, other regions may compensate, suggesting that the brain is highly malleable.

    This all means that the brain is an unpredictable organ. Much remains to be understood, and our understanding of which brain regions do what changes with each new brain study.

    How The Eyes Communicate With The Brain

    When we decide to look at something, a brainstem structure called the pons is called into action. It controls eye movement, constantly telling our eye muscles to move toward the correct stimulus of light .

    When light enters the eye through the pupil, it strikes in the retina called rods and cones. Rod cells are responsible forperipheral vision and night vision, while cone cells react to brighter light, color and fine details.

    When light hits its corresponding rod or cone, the cell activates, firing a nerve impulse through the optic nerve the middle man between the eye and the brain.

    This impulse travels across countless nerve endings and eventually ends up with our pal the occipital lobe, where its processed and perceived as a visible image. This is eyesight.

    Since an image isnt much help without meaning, the occipital lobe sends this visual information to the hippocampus in the temporal lobe. Here its stored as a memory.

    All of this happens within the tiniest fraction of a second, allowing us to perceive the world in essentially real time.

    The human brain is an incredibly complex web of neurons and synapses. And the more we understand about its mind-boggling ability to process and make sense of random collections of light, the more we can appreciate the equally complex world around us.

    What Are The Parts Of The Nervous System

    The nervous system is made up of the central nervous system and the peripheral nervous system:

    • The brain and the spinal cord are the central nervous system.
    • The nerves that go through the whole body make up the peripheral nervous system.

    The human brain is incredibly compact, weighing just 3 pounds. It has many folds and grooves, though. These give it the added surface area needed for storing the body’s important information.

    The spinal cord is a long bundle of nerve tissue about 18 inches long and 1/2-inch thick. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body.

    The brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae. They’re both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products.

    Understanding The Five Major Areas Of The Brain

    The parietal lobe is responsible for collecting the five senses sound, sight, touch, taste and smell to create a total awareness of what is currently happening. It interprets the data sent from other various data gathering areas of the brain that cannot connect the dots individually. The parietal lobe helps to create awareness of one …

    The Cerebellum: Back Of The Brain

    Behind the cerebrum at the back of the head lies the cerebellum. In Latin, cerebellum means little brain, but the cerebellum actually contains more nerve cells than both hemispheres combined. The cerebellum is primarily a movement control center, responsible for:

    • Voluntary muscle movements
    • Fine motor skills
    • Maintaining balance, posture & equilibrium

    Unlike the cerebrum, the left cerebellum controls the left side of the body, and the right cerebellum controls the right side of the body.

    What Is The Definition Of The 5 Senses

    The sensing organs associated with each sense send information to the brain to help us understand and perceive the world around us.. Furthermore, what are the 5 senses and how do they work? The classic five senses are sight, smell, hearing, taste, and touch. The organs that do these things are the eyes, nose, ears, tongue, and skin.

    Providing a Sense of Touch through a Brain-Machine Interface

    The brain has three main sections: the forebrain, the midbrain, and the hindbrain.

    The Forebrain

    The forebrain is the largest and most complex part of the brain. It consists of the cerebrum the area with all the folds and grooves typically seen in pictures of the brain as well as other structures under it.

    The cerebrum contains the information that essentially makes you who you are: your intelligence, memory, personality, emotion, speech, and ability to feel and move. Specific areas of the cerebrum are in charge of processing these different types of information. These are called lobes, and there are four of them: the frontal, parietal, temporal, and occipital lobes.

    The cerebrum has right and left halves, called hemispheres. They’re connected in the middle by a band of nerve fibers that lets them communicate. These halves may look like mirror images of each other, but many scientists believe they have different functions:

    • The left side is considered the logical, analytical, objective side.
    • The right side is thought to be more intuitive, creative, and subjective.

    So when you’re balancing your checkbook, you’re using the left side. When you’re listening to music, you’re using the right side. It’s believed that some people are more “right-brained” or “left-brained” while others are more “whole-brained,” meaning they use both halves of their brain to the same degree.

    In the inner part of the forebrain sits the thalamus, hypothalamus, and :

    What Are The Five Senses Of The Brain

    What are the five senses of the brain? Your brain collects information, like smells and sounds, through your five senses: sight, hearing, touch, taste, and smell. Each of your five senses has its own special sensor. What are mental senses? We are taught about our five senses from childhood: sight, smell, taste, touch, and hearing

    Neuroscience Of Touch: Touch And The Brain

    IntroductionHave you ever felt the touch of someones hand on your shoulder and found yourself letting go of tension you didnt even know you were holding? We can probably all remember the impact a touch has had on us, whether casually or in a therapeutic setting. As practitioners, we have daily experiences of the effects of touch on our clients. Current research in neuroscience is looking directly at the brains response to touch. Lucy Brown, a neuroscientist interested in studying alternative therapies, presented recent findings at a talk at Harvard Medical School. What follows is primarily my summary of her talk with a few comments from the point of view of a practitioner.

    Functional MRICurrent research tracks the impact of touch on the brain with functional MRI . FMRI can detect activity in different brain areas by measuring the increase in blood flow that is correlated with an increase in neuronal activity. While this research is still in its infancy, it holds some promise for elucidating what we intuit from our experience as practitioners and recipients of therapies based on touch. The studies are part of a new trend: to look for integration of response rather than investigating each part/function separately. The fMRI studies show that touch has a wide impact on the brain, influencing our sensations, our movements, our thought processes and our capacity to learn new movements.

    What Part Of The Brain Is Responsible For Smell And Taste

    What part of the brain is responsible for smell and taste? The parietal lobe gives you a sense of me. It figures out the messages you receive from the five senses of sight, touch, smell, hearing and taste. This part of the brain tells you what is part of the body and what is part of the outside world.

    What part of the brain is responsible for smell? The Olfactory Cortex is the portion of the cerebral cortex concerned with the sense of smell. It is part of the Cerebrum. It is a structurally distinct cortical region on the ventral surface of the forebrain, composed of several areas. It includes the piriform lobe and the hippocampal formation.

    What lobe of the brain is responsible for taste? The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch.

    Does smell affect memory? Therefore, smell has a more powerful impact on memory than the other senses. Not only does smell have a tight relationship with memories, but smelling something can trigger an emotional response related to the memory, without bringing up the memory.

    Psychology In Everyday Life: Why Are Some People Left

    Across cultures and ethnic groups, about 90% of people are mainly right-handed, whereas only 10% are primarily left-handed . This fact is puzzling, in part because the number of left-handers is so low, and in part because other animals, including our closest primate relatives, do not show any type of handedness. The existence of right-handers and left-handers provides an interesting example of the relationship among evolution, biology, and social factors and how the same phenomenon can be understood at different levels of analysis .

    At least some handedness is determined by genetics. Ultrasound scans show that nine out of 10 fetuses suck the thumb of their right hand, suggesting that the preference is determined before birth , and the mechanism of transmission has been linked to a gene on the X chromosome . It has also been observed that left-handed people are likely to have fewer children, and this may be in part because the mothers of left-handers are more prone to miscarriages and other prenatal problems .

    But culture also plays a role. In the past, left-handed children were forced to write with their right hands in many countries, and this practice continues, particularly in collectivistic cultures, such as India and Japan, where left-handedness is viewed negatively as compared with individualistic societies, such as Canada and the United States. For example, India has about half as many left-handers as the United States .

    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.

    Where Is The Brain Located

    How to learn major parts of the brain quickly

    The brain is enclosed within the skull, which provides frontal, lateral and dorsal protection. The skull consists of 22 bones, 14 of which form the facial bones and the remaining 8 form the cranial bones. Anatomically, the brain is contained within the cranium and is surrounded by the cerebrospinal fluid.

    The Cerebrospinal Fluid is a fluid that circulates within the skull and spinal cord, filling up hollow spaces on the surface of the brain. Every day, the specialised ependymal cells produce around 500mL of cerebrospinal fluid.

    The primary function of the CSF is to act as a buffer for the brain, cushioning mechanical shocks and dampening minor jolts. It also provides basic immunological protection to the brain.

    Furthermore, CSF provides buoyancy for the brain. i.e., the brain is suspended in a layer of CSF, wherein, the weight of the brain is nearly negated. If the brain is not suspended in CSF, it would be impeded by its weight, consequently cutting off the blood supply in the lower half of the brain. It would lead to the death of neurons in the affected area.

    Senses Brain & Nervous System

    The path starts with one of your senses detecting something. When this happens, a signal is sent through the nervous system to the brain. The brain processes the information and then decides on the action to take. It then sends a signal through the nervous system to the body part to take action. This entire process takes a split second to complete.

    Other Key Parts Of The Brain

    Ventricular SystemThe brain is not a solid organ. Instead, there are fluid-filled cavities within the brain called ventricles. The ventricles provide nourishment to the brain. The ventricular system produces and processes cerebrospinal fluid, a clear, watery substance flowing around the brain to cushion and protect it.

    Cranial NervesThe brain also contains 12 pairs of cranial nerves. Each is responsible for specific body functions.

    • Olfactory nerve: Sense of smell
    • Optic nerve: Vision

    Research Focus: Identifying The Unique Functions Of The Left And Right Hemispheres Using Split

    We have seen that the left hemisphere of the brain primarily senses and controls the motor movements on the right side of the body, and vice versa. This fact provides an interesting way to study brain lateralization the idea that the left and the right hemispheres of the brain are specialized to perform different functions. Gazzaniga, Bogen, and Sperry studied a patient, known as W. J., who had undergone an operation to relieve severe seizures. In this surgery, the region that normally connects the two halves of the brain and supports communication between the hemispheres, known as the corpus callosum, is severed. As a result, the patient essentially becomes a person with two separate brains. Because the left and right hemispheres are separated, each hemisphere develops a mind of its own, with its own sensations, concepts, and motivations .

    Although Gazzanigas research demonstrated that the brain is in fact lateralized, such that the two hemispheres specialize in different activities, this does not mean that when people behave in a certain way or perform a certain activity they are only using one hemisphere of their brains at a time. That would be drastically oversimplifying the concept of brain differences. We normally use both hemispheres at the same time, and the difference between the abilities of the two hemispheres is not absolute .
