Early first 12 years of brain growth via learning
In a study about human memory, brain growth and learning, the first 12 yrs of human growth and learning is very critical to the future brain health.
In contrast, the rats exposed to the shock compartment at 24 days of life learned and retained the memory for a long time and avoided this place—revealing a memory similar to that of adult rats.
Rats develop rapidly during infancy and become sexually mature at about 6 weeks of age. Humans, on the other hand, develop slowly and don’t hit puberty until about age 12-13 years (range: 8 to 16 years).
To address this, the scientists focused on the brain’s hippocampus, which previous scholarship has shown is necessary for encoding new episodic memories. Here, in a series of experiments similar to the box tests, they found that if the hippocampus was inactive, the ability of younger rats to form latent memories and recall them later by reminders as they got older was diminished. They then found that mechanisms of “critical periods” are fundamental for establishing these infantile memories.
A critical period is a developmental stage during which the nervous system is especially sensitive to environmental stimuli. If, during this period, the organism does not receive the appropriate stimuli required to develop a given function, it may be difficult or even impossible to develop that function later in life. Well-known examples of critical period-based functions are sensory functions, like vision, and language acquisition.
The study shows that there is a critical period for episodic learning and that during this period the hippocampus learns to become able to efficiently process and store memories long-term.
“Early in life, while the brain cannot efficiently form long-term memories, it is ‘learning’ how to do so, making it possible to establish the abilities to memorize long-term,” explains Alberini. “However, the brain needs stimulation through learning so that it can get in the practice of memory formation—without these experiences, the ability of the neurological system to learn will be impaired.”
These studies, the researchers observe, suggest that using learning and environmental interventions during a critical period may significantly help to address learning disabilities.

Answer by Connie b. Dellobuono:
That we can set our priorities based on data.
That data when grouped, analyzed and graphed can provide more information.
That past data can provide cues for the present.
That customer data can provide necessary feedback to better our service, product designs and create new innovations.
That data is king.

Why are confidence intervals more common than prediction intervals in medical papers?
Why are confidence intervals more common than prediction intervals in medical papers? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
Prediction intervals predict the distribution of individual future points, whereas confidence intervals and credible intervals of parameters predict the distribution of estimates of the true population mean or other quantity of interest that cannot be observed.
For example:
Confidence interval is better choice when finding association between ethnicity (minority vs. majority ethnic groups) and breast cancer survival : Crude association , association adjusted for model 1 parameters, association further adjusted for socioeconomic position. The size of each square is proportional to the precision of the estimate and hence to the weight contributed by the individual study to the meta-analysis.

How is network science used in cognitive science?
How is network science used in cognitive science? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
Subsymbolic modeling includes Connectionist/neural network models. Connectionism relies on the idea that the mind/brain is composed of simple nodes and that the power of the system comes primarily from the existence and manner of connections between the simple nodes. Neural nets are textbook implementations of this approach. Some critics of this approach feel that while these models approach biological reality as a representation of how the system works, they lack explanatory powers because complicated systems of connections with even simple rules are extremely complex and often less interpretable than the system they model.

In what areas of public health is data science relevant?
In what areas of public health is data science relevant? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
As we analyze and collect data, we can use data science to focus what will add value or impact public health the most.
We can identify top health contributors, drill down to specifics and tailor fit service delivery based on data.
We can collaborate with doctors and health personnel on what data will be useful in the present and what past data can be of value to the present.

Does eating a ketogenic diet prevent Alzheimers? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
The brain needs high fat (coconut,avocado,walnut,peanut), healthy protein (eggs), less sugar (little honey,maple syrup and sugar from not so over rip fruits) and an intestinal gut of good microbes (can be balanced by acidophilus, pickled veggies, food rich in PQQ = parsley, kiwi, Natto, green tea, papaya).
The brain detoxes during sleep.
Exercise and learning new things grow neurons.
Prevent infection from entering the body (bacteria,virus,etc).
Ail for good oral hygiene and disease free teeth.
Avoid metal toxins, fumes and drugs/medications.
Massaging the brain is also cleansing just like fasting.
Love and care from love ones protect the brain from stress.
6 enemies of AD: obesity, tobacco, alcohol, drugs/medication overuse, inactivity, lack of brain food that boost the immune system
What can you eat or use to make your body immune to certin diseases?
What can you eat or use to make your body immune to certin diseases? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
A mouth wash of hydrogen peroxide, red colored veggies and fruits, citrus (rich in Vit C), zinc (oyster and clams, nuts) and chewing food well.
Astralagus and other herbs (parsley,turmeric,ginger, sulfur rich foods)
Massage (lympathic system) and sleep strengthens your immune system
Happiness and bonding with love ones perk up your immune system
Sweating and sleeping help detox your body.
Avoidance of non whole foods such as sugar, drugs,alcohol and preservatives can help you live longer.
Fasting is also helpful.
Chew raw garlic, bitter leaves and greens (green plantain cooked, bitter melon).
Remember that the smaller the seeds and fruit, the more nutrition they pack. The taller the tree, the more nutrients it derive from the soil. Chewing food well and eating only when hungry will help you absorb more nutrients. Avoid toxix people, relationship and environment (clean water, air, toxic free house materials and whole foods).

What are the possible causes of back pain with white discharge?
What are the possible causes of back pain with white discharge? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
Yeast infection is white vaginal discharge. Wash with diluted vinegar, avoid cheese and sugar and add acidophilus, raw and fermented veggies in the diet. Back pain has many causes (bacteria, virus and others) that your doctor can find out after some blood, urine and stool tests.

Answer by Connie b. Dellobuono:
The belief that the most popular antidepressant drugs raise serotonin levels in the brain is nothing more than a myth, a leading professor of psychiatry has claimed.
David Healy, head of psychiatry at the Hergest psychiatric unit in Bangor, North Wales, said the misconception that low levels of serotonin were responsible for depression had become established fact.
He suggested that the success of so-called SSRI drugs – which include Prozac and Seroxat – was based on the ‘marketing of a myth’.

Some meds put you to sleep and during sleep the brain detoxes. Volunteering helps with depression and whole foods and exercise are very important too.
