• EEG recordings has poor spatial resolution - the most critical limitation - and are most sensitive to a particular set of post-synaptic potentials.
• EEG recordings do not directly capture axonal action potentials.
• EEGs capture dendritic currents almost exclusively (as opposed to axonal currents) - but they also show a preference for activity on populations of parallel dendrites and transmitting currents in the same direction at the same time.
• EEG provides information with a large bias to select neuron types, and should be used carefully on statements regarding global brain activity.
• It is mathematically impossible to reconstruct a unique intracranial current source for a given EEG signal, as some currents produce potentials that cancel

It also helps the student to develop interest in studies more than they would have ever learned while in other high-frequency brainwaves.
It has been noted that induced Alpha Waves enable the student to assimilate more information, with greater long-term retention. The brainwave indicates a relaxed state of mind, good for inspiration and the ability to learn fast. There is more understanding of the role of Theta Brainwaves in behavioural learning, because this state indicates a high state of mental concentration. The presence of Theta Brainwaves has been associated with increased receptivity for learning and decreased filtering by the left hemisphere.
How Brainwaves Affect Our Work and Relationships
Brainwaves play very vital roles in our work, relationships and every other aspect of our lives. Listening to brainwave music acts as a form of meditation, which has been found to help prepare the human brain for daily work, reduce the risk of illnesses, decrease stress levels and keep one in the right frame of mind at all

However, anatomically speaking, they are remarkably different. Our physiology is wired such that the left-brain controls the right part of the body, while the right-brain controls the left part. For instance, when we see something from our left eye, the image is processed in the right part of the brain. If the right part of the brain is damaged for some reason, the left part of our body will be affected.
The understanding of the two hemispheres and how they perform was first studied in the 1960s. American psychologist and biologist Roger W. Sperry began his research in this field, and he discovered that a single human brain has very distinct ways of thinking, processing information, and functioning.
The right side of the brain, he discovered, had the potential to look at things holistically. The right side would consider the big picture, and process information in its entirety. The left side of the brain, on the other hand, broke information into tiny units, and analysed each of these units separately. It then pieced the information together to obtain a more logical and sequential
For example, when researchers were working with the mental mirror box, a box that tricks the brain of a patient with a nonexistent limb that the limb is actually there by reflecting the healthy limb, they found that the individual feels as if the limb is present and healthy. Researchers also found that if an individual scratches a particular spot on his or her face, that fulfills the itching sensation that was previously felt on the nonexistent arm. This is because when one area of the brain is not being used, such as the arm map when the arm is amputated, another part of the brain map takes over, such as the face. This is an extremely interesting finding which explains why blind or deaf individuals experience such profound functioning in their other
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
The video Severed Corpus Callosum by the Scientific American Frontiers describes the case of a split-brain patient Joe. The recording starts on the campus of Dartmouth College in New Hampshire where Dr. Mike Gazzaniga, one of the leading scientists of this place has been working with Joe, a man with two brains for over a decade. Doctors have to perform brain surgery to correct his epileptic problem and to stop the daily seizures that were affecting his life. The procedure severed the connection between the two halves of his brain cutting the corpus callosum to prevent the spread of the electric storms that causes seizures. Yet, it also stopped the communication between the left and right halves of his brain.
Fourth Experiment Forty-eight children under the age of 18 who had suffered an unprovoked seizure were studied in Lung-Chang’s experiment. Exclusion criteria included current “neurodegenerative” ailments and absence of epileptic discharges. Parents and legal guardians of the children were asked for permission to included their child in the experiment. This study was conducted at the Kaohsiung Medical University Hospital. The subjects were randomly placed in treatment and control groups using computer generated group lists.
Firstly, the human brain is a complex organ that commands a variety of different functions within the human body. One specific function of the human
Split-brain concepts have been explored for almost a century. The study has opened up many new frontiers of brain research. These new frontiers have uncovered hemispheric specialization and provided more focus on brain regions. The initial research into split-brain was due to neurologists trying to find new ways of solving neurological disorders. The first sign of split brain was in the 1940s.
An adult brain contains about 100 billion nerve cells or neurons. But these cells need to communicate so that the brain can function well. If humans use words to communicate, while the dogs bark, bees dance and birds sing, neurons communicate with neurotransmitters! These neurons communicate with each other by sending signals in the form of tiny electrical charge that travel through their branches forming synapses. When a charge reaches a synapse, it may trigger release of tiny bursts of chemicals called neurotransmitters.
This is essential for the change in the brain. When the brain is distracted, inattentive, and doing something unmindfully, the brain
The human brain is one of the most complex organs which is being studied in depth, in today’s world. It is the central command center, weighing just three pounds but, it controls the whole body from head to toe. Numerous studies are being held to see how the brain really functions. After a long stretch of research, scientists have not yet understood how the brain works and are thoroughly doing research about this. In psychology the human brain is studied based on how an individual thinks, feels, and behaves.
“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” - World Health Organisation, 1946. Although there have been a number of ground breaking discoveries in science as a whole I strongly believe more can be done within neurology. Epilepsy affects more than 500,000 people in the UK that is almost one in every 100 people. I wish to study neuroscience as I would like to look into conditions such as this but also explore into neuroaesthetics. Having a close family member being diagnosed with epilepsy, I have been exposed to the fundamental importance of how to deal with seizures.
In our present day and age many people now listen to music while doing a number of various activities. There is a big debate whether listening to music benefits you and helps you to concentrate and focus especially while studying. I researched whether listening to music helps you concentrate and focus. Listening to music is one of the only activities which involve using both sides of the brain. When concentrating on a specific task you are normally only using one part of your brain while concentrating so the other parts of your brain that is unoccupied drifts off which causes you to lose concentration.
There are many kinds of music which will influence human behavior in either good or bad ways. Music has a strong effect on people. Music like oldies or classical selections make people to feel happier and friendlier (Wade, L). Jobs require high concentration such as dentists, radiation therapists
2. When use correctly, certain music has shown to improve mental health and the mind. a) “Listening to music on headphones reduces stress and anxiety in hospital patients before and after surgery” (Collingwood,
Along with affecting the brain music has a certain impact on emotions. Research indicates that music stimulates emotions through specific brain circuits. The impact of music is easily influential on the brain. We can see the impact of the brain engaging in mood and emotion when a young child smiles and begins to engage in the rhythm of the music. We can also see the impact when a parent and their child connect through music.
Mainly, listening to music has the ability to boost up a person’s mood instantaneously, affecting a person inner mind where different negative thoughts feed on a person’s abhorrence. For an example, listening to music while driving can positively rock mood instantly. In addition, listening to music can have a largely effect on a person’s minds and a person’s body. Later, listening to music also reduces stress, anxiety and depression that lead a person becoming calm and soothing. Some experts said music really does help people lead to a better mood and get in touch with their feelings.
