Music and brain

How do music appreciation and emotions emerge in the human brain?

Infants show sophisticated abilities to acquire knowledge about musical syntax. This strongly supports the notion that musicality is a natural ability of the human brain. There is a natural connection between music and speech and the neural resources for music and language processing in both adults and children seem to be partly overlapping. We intend to find out how very young infants process violations of language-related and musical principles. Children react differentially to music, as they do to everything they encounter. These differences in the styles of reactivity may be due to 1) temperament, the permanent physiology-based property of all humans, 2) learning in the early years – mimicking the reactions of other people lead the child to react in similar ways, 3) possibly to differences in the brain processes related to the processing of auditory input. The detection accuracy of the auditory system to changes of different types (for example, changes in melody, compared to changes in rhythm) differ greatly between individuals. We will address the importance of this detection profile to the reaction styles of children towards music.  

 

Eat Smart for a Healthier Brain

Add these 'superfoods' to your daily diet, and you will increase your odds of maintaining a healthy brain for the rest of your life.

Wild salmon. Deep-water fish, such as salmon, are rich in omega-3 essential fatty acids, which are essential for brain function, says Kulze. Both she and Pratt recommend wild salmon for its "cleanliness" and the fact that it is in plentiful supply. Omega-3s also contain anti-inflammatory substances. Other oily fish that provide the benefits of omega-3s are sardines and herring, says Kulze; she recommends a 4-ounce serving, two to three times a week.


Nuts and seeds. Nuts and seeds are good sources of vitamin E, says Pratt, explaining that higher levels of vitamin E correspond with less cognitive decline as you get older. Add an ounce a day of walnuts, hazelnuts, Brazil nuts, filberts, almonds, cashews, peanuts, sunflower seeds, sesame seeds, flax seed, and unhydrogenated nut butters such as peanut butter, almond butter, and tahini. Raw or roasted doesn't matter, although if you're on a sodium-restricted diet, buy unsalted nuts.


Avocados. Avocados are almost as good as blueberries in promoting brain health, says Pratt. "I don't think the avocado gets its due," agrees Kulze. True, the avocado is a fatty fruit, but, says Kulze, it's a monounsaturated fat, which contributes to healthy blood flow. "And healthy blood flow means a healthy brain," she says. Avocados also lower blood pressure, says Pratt, and as hypertension  is a risk factor for the decline in cognitive abilities, a lower blood pressure should promote brain health. Avocados are high in calories, however, so Kulze suggests adding just 1/4 to 1/2 of an avocado to one daily meal as a side dish.


Whole grains. Whole grains, such as oatmeal, whole-grain breads, and brown rice can reduce the risk for heart disease. "Every organ in the body is dependent on blood flow," says Pratt. "If you promote cardiovascular health, you're promoting good flow to the organ system, which includes the brain." While wheat germ is not technically a whole grain, it also goes on Kulze's "superfoods" list because in addition to fiber, it has vitamin E and some omega-3s. Kulze suggests 1/2 cup of whole-grain cereal, 1 slice of bread two-thee times day, or 2 tablespoons of wheat germ a day.

10 facts about brain

These facts will teach you interesting bits of information about the physical make-up of the human brain.

1. Weight. The weight of the human brain is about 3 lbs.
2. Cerebrum. The cerebrum is the largest part of the brain and makes up 85% of the brain’s weight.
3. Skin. Your skin weighs twice as much as your brain.
4. Gray matter. The brain’s gray matter is made up of neurons, which gather and transmit signals.
5. White matter. The white matter is made up of dendrites and axons, which create the network by which neurons send their signals.
6. Gray and white. Your brain is 60% white matter and 40% gray matter.
7. Water. The brain is made up of about 75% water.
8. Neurons. Your brain consists of about 100 billion neurons.
9. Synapses. There are anywhere from 1,000 to 10,000 synapses for each neuron.
10. No pain. There are no pain receptors in the brain, so the brain can feel no pain.

The brain and skin sensation

If something lands on my left hand, this information will be transmitted to the right side of my brain. It goes to the area of the brain next to the area that deals with movement. The tactile area of the brain deals with physical sensation. Movement and feeling are closely related, so it makes sense that they are next to each other in the brain. Because movement and tactile areas are located close to each other, it is not uncommon for people with a brain injuries to lose both movement and feeling in parts of their body. Remember--tactile information from the left side of the body goes to the right brain, just like movement and vision.

IS THE BRAIN ONE BIG COMPUTER?

Is the brain like a big phone system (because it has a lot of connections) or is it one big computer with ON or OFF states (like the zeros and ones in a computer)? Neither of the above is correct.

Let's look at the brain using a different model. Let's look at the brain as an orchestra. In an orchestra, you have different musical sections. There is a percussion section, a string section, a woodwind section, and so on. Each has its own job to do and must work closely with the other sections. When playing music, each section waits for the conductor. The conductor raises a baton and all the members of the orchestra begin playing at the same time playing on the same note. If the drum section hasn't been practicing, they don't play as well as the rest of the orchestra. The overall sound of the music seems "off" or plays poorly at certain times. This is a better model of how the brain works. We used to think of the brain as a big computer, but it's really like millions of little computers all working together. 

Hi!
Welcome to this space my name is Marco and I hope you enjoy the articles that I will write.


I want yo share with you a very interesting documental that talk about how our brain works and respond immediately in a dangerous situation.
