What are the differences between human brain and sheep brain?

The human brain is larger.

The positioning of the hind brain is different, due to the erect position of humans.

Convolutions are increased in humans (increases surface area).

The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors).

There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).

What happens when the brain is starved of oxygen on a regular basis?

Anoxia is damaging to brain cells. Without O2, cellular respiration will not function, which means that brain cells must use up what little reserves they have in the way of cellular energy (called ATP) to maintain their membrane potentials. Without restoration of O2 cells will become necrotic (i.e., their membrane potential will run down, they will lyse and die). Often this will be accompanied by neighbouring cells becomming apoptotic (programmed cell death).

What happens with your brain when you think?

It becomes more active. You can see, on an EEG, more "firing" of the neurons.

How much percentage of brain is used?

There is a wide-spread myth that humans only use 10% of their brain. While no hard percentage has been published, studies of the brain and imaging technology reveal that almost all of the human brain is being used at any given time.

What are three ways that the outside world communicates with us?

The internet, phones, and television are three ways the world communicates. While telephones and the internet accept input from the user, television is usually just a one-way communication.

Does white beans contain serotonin?

White beans do not contain serotonin itself, but they are a good source of nutrients that can support serotonin production in the body. They are rich in carbohydrates, fiber, and protein, which can help regulate mood and promote overall brain health. Additionally, they provide essential vitamins and minerals, such as folate and magnesium, that contribute to the synthesis of serotonin.

Is iMusic brain enhancer a hoax?

For those that don't know what iMusic is, visit www.getimusic.com

It's some sort of music which is said to be able to greatly enhance your brain performance, increasing your IQ, energize your body, or even increase your physical feats (muscle, endurance, injury reduction, etc) according to its release package.

On their website they say that their technology has been proven. And indeed they give tens of references of studies that have been done during the last few decades. Most of these are about some form of brainwave training and neurofeedback. None of those is specifically about iMusic. They have also done a few (I found three) studies themselves with very small test groups (nine to ten people per group) that showed clear results in favour of their product. But a) the study groups are too small to be significant, and b) significant details are not given in the research briefs. While in all tests one group was asked to listen to "enhanced" music, it is not clear whether the other group listened to the same music only that it was not "enhanced", or whether they listened to completely different music. I even sent an inquiry to Volition about these questions, but got no useful answer. No information beyond the nearly useless research briefs. There is no doubt that music has an effect on the brain. From the evidence provided on the iMusic website (assumed that there are no lies) it cannot be said whether the "enhancement" has an additional positive effect or not. Since they give a lot of references that are not directly related to the product, I assume that there has been no significant research directly related to iMusic. Since it is hardly possible to do any double blind testing, it will be hard to prove or disprove the effectiveness of iMusic as compared to a good choice of "normal" music. I'm convinced of one thing, though: it will work - to some extent - if you really believe in it.

What part of the brain controls hearing?

The Primary Auditory Cortex is responsible for hearing and it is located in the superior aspect of the temporal lobe and performs the basics of hearing; pitch and volume.

Damage to which of these areas would most likely cause death optic chiasm medulla temporal cortex or prefrontal cortex?

Assuming the damage did not involve an infection, the medulla. The medulla controls autonomic functions like respiration and blood pressure, which you do not consciously control. As these functions are vital to staying alive, losing function of the medulla would most likely cause death.

Damage to the optic chiasm could cause full or partial blindness, depending on the location of the damage. Damage to the temporal cortex could result in impairments in object perception as well as memory. Damage to the prefrontal cortex could result in impairments of executive functions, some examples of which include working memory (holding an item, like a phone number, in mind), decision making, and problem solving.

Which of the following occurs on a daily basis A circadian rhythm and the tides B circuit rhythm and triads C circular rhythm and half moon phase D circumstance rhythm and full moon phase?

The human body has a 24 hour circadian rhythm.The Earth's oceans have tides that occur every day.


They aren't scientifically connected to each other in any known way(s), though many people say tides and weather affect sleep patterns and enhance or disrupt the body's circadian rhythm.
