Female brain shrinks after birth and it takes months for it to return to the natural size if it does And im pretty sure that after a few weeks with no sex women and men think about it the same amount of times..
Female brain Is very Beautiful. I stay with onw ao i see daily. Loves
Oh really !!!! Surprised to read it.I was thinking I am the most intelligent being a male and all females have always shrunken brain.lolz
The Bell Curve applies to the generalizations. There are always the small percentage that are out of the majority.
Wow, I was just waiting for all the hardcore feminists in the comments section complaining about this and I have to say, Im a little disappointed
Awww come on peeps, life is fun and data biases Bell curves, Our anatomies somehow always manage to find a way to continue our species, at least so far. No need to get bent. Read it, do more research if wished, get many Expert opinions and somehow your brain will process it as its wont. Think about it. Talking is fun, eating is fun, drinking is fun, and sex is fun. Mother Nature seemed to have figured it all out, so have fun. Getting bent is Not fun, in my book. I am a Male, father of three, was married 57 years and still love women for and mostly for all their foibles.
The Truth Behind Women’s Brains
Recent reports show that newborn males and females have very different brain circuitry, and hormones dramatically shape their future thoughts, feelings and behavior in the first years of life.

“The day they’re born their circuitry is already pretty much wired,” says Dr. LouAnn Brizendine, a neuropsychiatrist and author of the new book “The Female Brain.” “They’re either formed as a male brain or a female brain.”
Brizendine says that after eight weeks in utero all children’s brains appear exactly the same: female. Female is nature’s default setting. It is only after a surge of testosterone that boys’ brains begin to look male.
Recent studies reveal that after birth girls are already better at reading faces and hearing human vocal tones. Incredibly, during the first two years of life a baby girl’s ovaries will pump adult levels of estrogen. From six to nine months, a boy’s testicles are flooded with adult levels of testosterone.
While the behavioral effect of all of this remains a mystery, conjectures have been made.
“The studies that were done with children around 12 months old where their moms went in a room with them and they were told not to touch an object,” recounts Dr. Brizendine. “The boys would just go right for the object and touch it. The girls would hear their mom’s voice, turn around, look at their mom’s face, and stop. Boys don’t hear the complete tones in the female voice.”

At What Age Is The Human Brain Fully Developed
While no specific age has been identified as the age at which the human brain is fully mature, the Washington Post relates that many scientists agree that the brain does not reach maturity until at least the mid-20s. Some studies suggest that the brain continues to develop into the early 30s.
Jay Giedd, a pediatric psychiatrist and the leading researcher for a study by the National Institute of Health, concluded that the region in the brain that controls risky behavior does not fully develop until around age 25. Additional studies at the Institute of Cognitive Neuroscience at the University College London used MRI scans on the brains of 200 individuals aged 7 to 27 and concluded that the prefrontal cortex of the brain, which governs decision making, was forced to work harder in young people than in the brains of older adults.
Children and young adults have more grey matter in their brains, and some researchers believe that this impedes the efficiency of young brains to process information. As people age, the amount of grey matter in the brain decreases and neural transmissions happen with much greater speed and efficiency.
The Washington Post reports that teenagers are four times more likely to be involved in car accidents and three times more likely to die in one. While science has not yet developed a correlation between changes in the brain and how it impacts behavior, many believe that more research needs to be done in this area.
Why Is 18 The Age Of Adulthood If The Brain Can Take 30 Years To Mature
Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take place well into oneâs 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
At what age does someone become an adult? Many might say that the 18th birthday marks the transition from childhood to adulthood. After all, thats the age at which people can typically join the military and become fully independent in the eyes of the law.
But in light of research showing our brains develop gradually over the course of several decades, and at different paces among individuals, should we start rethinking how we categorize children and adults?
There isnt a childhood and then an adulthood, Peter Jones, who works as part of the epiCentre group at Cambridge University, told the BBC. People are on a pathway, theyre on a trajectory.

Its not about guilt or innocence The question is, How culpable are they, and how do we punish them?â

Nimh The Teen Brain: 7 Things To Know
Here are 7 things to know about the teen brain: 1. The brain reaches its biggest size in early adolescence. For girls, the brain reaches its biggest size around 11 years old. For boys, the brain reaches its biggest size around age 14. But this difference does not mean either boys or girls are smarter than one another! 2.
What Does Having An Older Brain Mean
Its unclear so far if there is significance to having a younger brain.
This research is a first of its kind and the authors of the study are only beginning to explore what they might use this data to understand and predict.
Its not that mens brains age faster. They start adulthood about three years older than women and that persists throughout life, says Dr. Manu Goyal, an assistant professor of radiology at Washington Universitys Mallinckrodt Institute of Radiology and an assistant professor of neurology and of neuroscience. What we dont know is what it means. I think this could mean that the reason women dont experience as much cognitive decline in later years is because their brains are effectively younger, and were currently working on a study to confirm that.
The study, which was published in the Proceedings of the National Academy of Sciences of the United States of America, is seen as an important step toward understanding gender differences in health and medicine.
This study theorizes that factors that influence brain development, including sexual differences, and exposure to different hormonal, inflammatory, and immunological environments during development, might be very important in determining how brain aging actually plays out, says Dr. Verna R. Porter, a neurologist and director of the Alzheimers disease program at Providence Saint Johns Health Center in California.
Men and women alike can take steps to improve their brain health.

Detrimental Influences Upon Brain Development
Unfortunately many people are exposed to things that may have a detrimental impact on the development of their brain. These include negative social influences, substance abuse, and/or prolonged levels of high stress. Although some people will have more resilient brains than others as a result of genetics, it is recommended to minimize exposure to problematic stimuli and scenarios.
Adolescent Maturity And Policy In The Real World: Scientific Complexity Meets Policy Reality
The most prominent use of neuroscience research in adolescent social policy was the 2005 U.S. Supreme Court Case, Roper vs. Simmons, which has been described as the âBrown v. Board of Education of âneurolaw,ââ recalling the case that ended racial segregation in American schools . In that case, 17-year-old Christopher Simmons was convicted of murdering a woman during a robbery. Ultimately, he was sentenced to death for his crime. Simmonsâ defense team argued that he did not have a specific, diagnosable brain condition, but rather that his still-developing adolescent brain made him less culpable for his crime and therefore not subject to the death penalty. Amicus briefs were filed by, among others, by the American Psychological Association and the American Medical Association summarizing the existing neuroscience evidence and suggesting that adolescentsâ still-developing brains made them fundamentally different from adults in terms of culpability.
The AMA brief argued that: âdolescentsâ behavioral immaturity mirrors the anatomical immaturity of their brains. To a degree never before understood, scientists can now demonstrate that adolescents are immature not only to the observerâs naked eye, but in the very fibers of their brainsââ . . The neuroscientific evidence is thought to have carried significant weight in the Courtâs decision to overturn the death penalty for juveniles .

Healthy Neural Networks In Teens
Another essential part of a developing brain is the network of neurons. This large network in the brain allows cells to communicate with one another, carrying signals back and forth between the brain and the rest of the body. Research points to the fact that a healthy mind means the ability for that network of neurons to change.
As a teen grows and learns, neurons form connections that can last a lifetime. However, a healthy brain is one that can be plastic, adaptable, and continue to change with its environment. The adolescent brain is undergoing incredible growth. Neurons are wiring and new connections between the two hemispheres of the brain are forming. This kind of growth and connection is an explosive time during adolescence. If the brain can continue to be plastic, that is if new neural connections can continue to form and if old ones can be released, this is can support healthy brain function and even a teens mental health. These neural connections and adaptability are important in an adolescents learning, behavior, and mood regulation. If a teens brain forms connections that support their mental health, these neural connections will then carry into adulthood support their psychological well being throughout the lifespan.
Regressive Events In The Postnatal Period
Cell Death in Glial Populations
As described above, brain development involves overproduction of neurons and glial cells, neural processes, and synapses. Although neural apoptosis has its peak during prenatal life, apoptosis in glial cell populations has a time course corresponding to the protracted postnatal time course of differentiation from glial precursors. During the period of initial myelination, many excess oligodendrocytes undergo apoptosis a few days after differentiating, and there is evidence that this process depends on signals from nearby axons, such that the number of surviving oligodendrocytes matches the local axonal surface area .
Synaptic Exuberance and Pruning
Although the development of neural networks requires the formation of precise connections between developing neurons and their targets, it is well documented that initial patterns of connectivity in the developing brain are exuberant in terms of both the numbers of connections formed and their topography. This exuberance can be observed on two very different time scales that appear to support different aspects of the process of emerging connectivity in the developing brain. At a macroscopic level, exuberance and pruning can be observed within major brain areas and pathways on timescales that extend over months or even years. But at a microscopic level very rapid formation and retraction of connections can be observed at the level of individual neurons over periods of minutes or hours.

The Adolescent Brain In Context
Neuroimaging technologies have made more information available about the structure and function of the human brain than ever before. Nonetheless, there is still a dearth of empirical evidence that allows us to anticipate behavior in the real world based on performance in the scanner . Linking brain scans to real-world functioning is hampered by the complex integration of brain networks involved in behavior and cognition. Further hindering extrapolation from the laboratory to the real world is the fact that it is virtually impossible to parse the role of the brain from other biological systems and contexts that shape human behavior . Behavior in adolescence, and across the lifespan, is a function of multiple interactive influences including experience, parenting, socioeconomic status, individual agency and self-efficacy, nutrition, culture, psychological well-being, the physical and built environments, and social relationships and interactions . When it comes to behavior, the relationships among these variables are complex, and they change over time and with development . This causal complexity overwhelms many of our âone factor at a timeâ explanatory and analytic models and highlights the need to continually situate research from brain science in the broader context of interdisciplinary developmental science to advance our understandings of behavior across the lifespan .
Brain Development In The Fetal Period
The fetal period of human development extends from the ninth gestational week through the end of gestation. The gross morphology of the developing brain undergoes striking change during this time. The human brain begins as a smooth, lissencephalic structure and gradually develops the characteristic mature pattern of gyral and sulcal folding. The formation of gyri and sulci follows an orderly sequence. Primary sulci are first seen as grooves positioned in specifically targeted brain regions, secondary branches then begin to form off the primary sulci, followed later by the tertiary branches. The first fissure to form is the longitudinal fissure that separates two cerebral hemispheres. Its development begins in rostral regions as early as GW8 and proceeds caudally until it is complete at GW22. Other primary sulci form between GW14-26. These include: Sylvian, Cingulate, Parieto-Occipital and Calcarine Central and Superior Temporal and Superior Frontal, Precentral, Inferior Frontal, Postcentral, and Intraparietal . Secondary sulci emerge between GW30-35 formation of tertiary sulci begins during GW36 and extends well into the postnatal period.

Behavioral Problems And Puberty
It is now known that hormones are not the only explanation for erratic adolescent behavior hence, investigators are now trying to establish the exact nature of the interrelationship between pubertal processes and adolescent brain maturation. Dahl has explained three main categories of brain changes related to puberty: changes that precede puberty changes that are the consequence of puberty and changes that occur after puberty is over. The timing of these changes may underlie many aspects of risk-taking behavior. These changes, which are the consequence of puberty, occur primarily in the brain regions closely linked to emotions, arousal, motivation, as well as to appetite and sleep patterns. Brain changes independent of puberty are those related to the development of advanced cognitive functioning.
The Brain Does Not Finish Developing Until After Youth
The area of the brain that takes the longest to mature is the prefrontal cortex, located in the frontal lobes. This part of the cortex is closely related to controlling behavior, reasoning, problem-solving, etc.
However, although brain maturation ends in youth, neurogenesis continues to occur in certain areas.
Furthermore, brain plasticity is maintained, although to a lesser degree than in childhood, and new brain connections can still be established through training and strengthening of neural connections. This is the basis of brain plasticity.

Content: Brain Maturation Is Complete At About 24 Years Of Age
The major reason that adolescents have different sensitivities to alcohol compared to adults is that their brains are still maturing. Although it was once thought that the brain is fully mature around birth this hypothesis has been disproven now there is clear evidence that the brain does not mature fully until about age 24. One of the areas of the brain that matures late is the prefrontal cortex the area important in impulse control risk-taking behavior and judgment.
During development in the womb as many as 250,000 new neurons are created each day. These neurons use spatial and chemical cues to find their synaptic targets. By the time we are born our brains contain billions of neurons with trillions of connections. However the infant brain contains far more neurons than are present in the adult brain.
During the subsequent months and through adolescence careful pruning of neuronal connections eliminates all but the most useful connections between neurons. The result is a thinning-out process that selects for those neuronal connections strengthened through repeated experience. In this sense cells that fire together wire together while those that do not make meaningful contacts do not survive. In other words use it or lose it! These early pruning processes not only establish the neuronal networks to support learning throughout life but also allow the brain to be sculpted based on a persons unique experiences.
