How can someone suppress intrusive memories for one entire day?
We're not sure that this is even possible, and our sources say that it definitely is not advisable. Intrusive memories are intrusive for a reason; they indicate that something has not been dealt with, and any luck in finding a way to suppress them will just invariably lead to larger psychosomatic issues.
You would be much better served to confront the memories, with assistance if need be, to resolve the issue. No matter how painful this might seem, it bears repeating that avoidance will lead to serious additional issues.
Where is the cornea located in the brain?
The cornea is actually part of the eye, and is a protective covering that is responsible for making sure that the eye is not damaged.
What is an antidepressant and how does it work in the brain?
Medications known as selective serotonin reuptake inhibitors (SSRIs) delay the reuptake of one of these neurotransmitters, serotonin, thus raising levels in the brain. Higher levels of serotonin seem to help the brain send and receive messages more easily, which, in turn, improves mood. SSRIs are very popular because they seem to have the least side-effects among antidepressants. Additionally, side-effects tend to be mild to moderate and are transitory, usually disappearing after one to three weeks.
Tricyclic antidepressants (TCAs), work in the same manner as SSRIs, but affect the uptake of all three neurotransmitters associated with mood: serotonin, norepinephrine and dopamine. They do have more side-effects, however, and can be dangerous if overdosed. TCAs are not recommended to patients with heart trouble.
Monoamine oxidase inhibitors (MAOIs), an older class of antidepressants, increase levels of all three neurotransmitters by inhibiting an enzyme responsible for inactivating them. MAOIs also affect tyramine, a molecule inked to blood pressure; as a result, anyone taking MAOIs must stick to a very strict diet that forbids a variety of common foods like cheeses, yogurt, certain meats, bananas, and many more foods. Failure to do so can lead to a hypertensive crisis and may result in death. MAOIs also interact with many medications and are no longer widely prescribed.
How do people wake up before their alarm goes off?
People can wake up before their alarm goes off due to their body's internal clock, or circadian rhythm, which regulates sleep and wake cycles. Factors such as stress, excitement, or anticipation can also cause individuals to wake up before their intended alarm time.
Is depth perception of a human being learned or innate?
Depth perception in humans is a combination of both innate abilities and learned experiences. While some aspects, like binocular vision, are innate and present from birth, our brain learns to interpret depth cues over time through visual experiences and interactions with the environment. This development continues throughout life and can be influenced by factors like individual neuroplasticity and exposure to different visual stimuli.
Depends on which feelings you're interested in.
The paliocortex (aka the thalamus or brain stem) runs the "deepest" emotions,
the olfactory lobe locks in the strongest conscious emotions,
but every specialized section of the brain controls the feelings that are associated with that particular function. i.e. the visual lobe triggers emotion based on things you are seeing, have seen, and imagine that you see.
Functional magnetic resonance imaging (fMRI) would be most useful for detecting the brain areas that are most active as a person performs mathematical calculations. fMRI measures changes in blood flow related to neural activity, providing detailed images of brain activity during specific tasks. This method can help identify regions of the brain that are involved in mathematical processing.
What can you do to decrease your chances of getting a brain injury?
To decrease your chances of getting a brain injury, wear a helmet when biking, skateboarding, or participating in contact sports, use seat belts in vehicles, avoid risky behaviors like driving under the influence of alcohol or drugs, and take steps to prevent falls in older adults by removing trip hazards in the home.
Which brain structure plays a key role in sensory integration?
The thalamus plays a key role in sensory integration by relaying sensory information from various parts of the body to the cerebral cortex. It filters and directs this information to the appropriate areas of the brain for further processing.
What might be the result if a person's cerebellum was damaged?
The person might have difficulty with overall coordination and lose their senses because this is one of the most important parts of your brain and with out senses you couldn't see, hear, touch, taste, or smell anything
What part of the brain controls rage?
The amygdala, an almond-shaped structure in the brain, plays a key role in processing emotions like anger and fear. It is involved in triggering the body's fight-or-flight response and can contribute to the experience of rage when activated. Additionally, the prefrontal cortex is responsible for regulating and inhibiting impulsive and aggressive behaviors, so dysfunction in this area can also impact rage control.
The difference between monocular cues and bioncular cues?
Binocular cues are, "Depth cues that depend on the use of two eyes" (Myers, D., 2007, p. 245).
Monocular cues are, "Depth cues available to either eye alone" (Myers, D., 2007, p. 247).
Basically binocular cues are things that help us to perceive depth and we have to use both eyes to perceive them. Monocular cues are the same thing, but you can use only one eye or the other and still see the same effect.
Depth effects that depend on both eyes working at the same time (binocular) are Retinal Disparity and Convergence.
Depth effects that depend only on the use of one eye are: Relative size, Interposition, Relative clarity, Texture gradient, Relative height, Relative motion, Linear perspective and Light and shadow.
What guides the development of the brain for both an individual and a species?
For an individual, genetics and early experiences influence brain development, shaping neural connections and structures. For a species, evolution drives the development of shared brain structures and functions that bestow survival and reproductive advantages over time. Both nature (genetics) and nurture (environmental experiences) play crucial roles in shaping brain development.
What side of the brain controls language in most people?
In most people, language is primarily controlled by the left side of the brain. This area, known as the left hemisphere, is typically responsible for language processing, speech production, and comprehension.
Why do people murder What happens in the brain?
I don't know what can possibly be in there minds. I hurt everyday living with the pain of losing someone to Murder. Its obvious the Red Flags that went up that night but noone cared they covered it up and the Death was roled out as accidental. Don't do it if that why your reading this. It causes to much pain..And you would regret it the Rest of your life.
The 40 yr NHF study proves serum albumin in the CSF is the factor that cleans the brain however the level in the serum must be >47g.l and >240 mg in the CSF to remove the wastes such as amyloid. Inflammation controls albumin more than diet.
Why is corpus callosum important in the development of the brain?
It is where the two side of the brain the left and right do not communicate with each other so for an example if you are telling your self to move your right arm it may take a while for the left side to assist in what you want it to do
What part of the brain affects handwriting?
Handwriting is primarily controlled by motor regions in the brain, particularly the primary motor cortex and supplementary motor area. These regions coordinate the precise muscle movements needed for writing. Damage to these areas can result in changes to an individual's handwriting.
What does the perfect woman look like physically Her hair eyes nose height skin breast size?
There is no such thing as a "perfect woman" however when selecting a dating partner you shouldn't only focus on her physical traits.
Age
Personality
Common Intrests abd backround similarities
Values and Goals
And
Physical Traits
All of the answers you are going to receive are going to be based on personal preference to that person therefore making our comments useless
What percentage of people are left handed?
It varies, it is between 7-10% of the population
Also, it depends on what you call "left-handed". Does that mean you write with it? What if you write with the left and do everything else, like play the guitar and throw baseballs with the right? There's a few people out there that only use their left hand for writing and it feels more natural to use the right for nearly everything else. (The opposite of that is also true.)
For a number, though, when taking into account old people and young, the number is usually right around 7%. When looking at schools now, it is usually working out to right around 10%. I've actually noticed this... Usually high school (just a few years ago) there were about three left-handers in the class, me and two others, when class size was about 30 people.
I know there's a lot here, and it was a simple question, but I figured I'd try to open your mind a little.
Does touching the roof of your mouth stop a brain freeze?
Yes, touching the roof of your mouth with your tongue can help alleviate a brain freeze. The warmth from your tongue can help to slowly warm up the roof of your mouth and alleviate the cold sensation causing the brain freeze.
How does your brain selectively remember experiences?
The brain selectively remembers experiences by encoding and storing information that is deemed important or relevant, usually based on emotional significance or personal relevance. This process involves strengthening connections between neurons in a network and can also be influenced by factors like attention, repetition, and association with other memories. Additionally, the brain might prioritize short-term memory over long-term storage, focusing on retaining information that is currently useful or necessary.
What technology would be required to make a synaptic map of a living human's brain?
To create a synaptic map of a living human's brain, advanced imaging technologies such as electron microscopy combined with artificial intelligence algorithms would be necessary. These technologies would enable the high-resolution imaging and mapping of synaptic connections in real-time in a non-invasive manner. Additionally, the use of techniques like optogenetics to manipulate and understand the function of these synaptic connections could provide valuable insights into brain function and connectivity.
Does your brain continue to create neuron through out your life?
It's a bit ambiguous, if you mean by creating more cell then no, brain cell cease to duplicate once we reach a certain age around 2-3 years old (I'm not very sure about the time) since it's a highly specialized cell.
