Personality Neuroscience through integration of personality psychology、Theoretical and research methods of disciplines such as neuroscience，The potential neurological basis for research personality differences，Explore people in behavior、motivation、Emotional and Cognitive Biological Rooting Source。In recent years，Personality Neuroscience as an emerging field，Provides a new theoretical direction for the biological foundation of personality traits。Human experience and behavior are generated by the biological process，Especially the biological process of the brain。Based on this，We can think that the personality of these experiences and behaviors is related to the biological laws of the brain，This also makes the personality neuroscience have traces to follow。The use of neuroscience methods to study individual differences in psychology becomes easier and easier。Personality Neuroscience Under the complex interaction of genes and environment, the neuroscience explores the source of personality closest to the brain，and trace back to the peripheral source of these brain activity。Gene or environment has a continuous impact on personality，In the end, it will be reflected in the individual's brain changes。

In the past 30 years，The research on the five personality models of the big five，and has a high generality of cross -cultural general。Big Five Personality Models Assume that almost all characteristic adjectives can be classified by five remarkable fields: outer tilt、Nervous、Pyment、Deluity and openness。Early stages of the development of personality neuroscience，Linking personality traits with the foundation of neurological biology is very development prospects。Big Five Personality Model provides a classification scheme with practical value for personality neuroscience，It helps to ensure that the research results can be compared in different studies。Big Five Personality Model is an effective classification system for different cultures or racial individuals，Behavioral genetic research shows，These five personality bet365 Play online games traits are largely genetic。By establishing a model to identify the biological foundation of the five personality models and generate verified hypothesis，Big Five personality model can give play to its potential practical value for personality neuroscience。Personality traits are arranged as layers，Categorize the specific characteristics of interrelated associations in the overall characteristics。In a high -level personality level structure，The characteristics of the five personality models of the big five are originally considered independent，Each characteristic dimension of the big five personality model describes a main personality trait that clearly independent of other dimensions。Biological foundation is a unique existence of any trait。

Study on nerve imaging found，The brain activity in the rest state or to the internal and external dimensions of the brain area is positively related to the internal and external diligence in the brain area，These brain areas are particularly important in the circuit of rewards and trend behaviors。These brain areas include the inner orbital cortex、Veluation Core、almond nucleus and pattern。In addition，Geneticism Discovery，Internal and external dumping dimensions are interconnected with some genes and participated in the dopamine energy system。Internal and external dumping dimensions are related to the activation of cerebral cortex，The degree of cerebral cortex activation may depend on the reward nature of the scene，It may also be adjusted by dopamine。Some brain imaging research proof，Internal and outer dumping dimensions can predict the activity in the cerebral cortex area affected by dopamine (such as the front buckle)，These brain activities have no obvious emotional components when working on work memory。But the interesting thing is，Internal and outer dumping dimensions can not predict the ability of work memory。These findings explain that the emotion and cognitive process are interrelated。Internal and external dumping dimensions may be related to motivation to promote the difficult cognitive task of individual execution，It may even be related to the way of dealing with these tasks in the brain，and other personality traits, bet365 Play online games such as openness, may be more directly related to the performance of these tasks。Some studies found，Testosterone levels are linked to inner and outer dumping，Especially in close confidence and dominance。The impact of testosterone on internal and external dumping may be due to the interaction between testosterone and reward circuit，Especially the role in the voltage core。

　　Neuromatology

Neurotic reflection may be sensitive to threats，and a series of negative emotions and cognitive tendencies accompanied by threats and punishment，Including anxiety、Depression、Angry、Angry、Self -consciousness and fragility。The sensitivity to threatening is closely related to psychiatry and science because of the nervousness and threats，Therefore, there are a lot of research on the basis of its biological foundation。Many brain systems that respond to threats and punishments are related to neuropathic dimensions。Study on Neurological Imaging Discovery，In the brain area related to negative effects，Neurological dimension is related to the brain activity of the brain activity in a static state or a disgust/new stimulus reaction，These brain areas include almond core、Brain Island and front buckle bring back。genomics、Positive electron emission fault scan、Various methods such as psychiatric pharmaceutical operation and cerebrospinal fluid analysis confirmed，Neuromatous dimension is related to low levels of 5-hydroxylidine function。Nervous allergies are related to higher levels of norepinephrine。Neurotic dimensions are also related to high levels of stress semethyl cortisol，But when reacting to a specific pressure source，Low cortisol level。When dealing with threats and other pressure sources，Cortisol function related to neurotic quality is the same as the hypothalamus -pituitary -adrenaline axis。Last，Some brain electrical studies indicate，Neuromer (including multiple characteristic indicators of negative emotions) is related to the activation of the right querous leaf relative to the left brain。The right brain is more inclined to participate and avoid relevant emotions and motivation status，and the left brain is more inclined to participate and tend to be related emotions and motivation status。A problem that bet365 best casino games associates nervous with the right brain is that anger is related to the trend motivation，EEG research shows that anger is related to the activation of the left leaf。Therefore，Perhaps the asymmetry of the brain function helps distinguish the two different types of negative emotions found in the nerve dimension: the emotions related to the abstinence and the emotions related to instability and anger。

　　Pymo -human dimension

You may reflect the tendency of maintaining social stability，Including the degree tendency to reflect the degree of social (anti -social)。Biomonians This kind of altruistic tendency is of great significance for social species，Bades may be supported by the brain system involved in social information processing。More and more neurological biological system science is scientifically paired with empathy、Psychological theory and perceive biological movement and intention to study，These studies are related to the neurological foundation of youthfulness。The brain areas related to these social information processing forms include the inner frontal frontal leaf cortex、The temporal groove、At the junction of temporal ceiling、Mirror neuron system、Under the forehead, and the rear rear lobe cortex。In addition to the above -mentioned brain areas that are generally considered to participate in social information processing，Other brain areas are also related to the characteristics of pleasant nature。Research Discovery，When observing the person you love experienced pain，The brain activity of the brain activity of emotion and brain island and front buckle (area involving painful emotional ingredients)。Same as nerve，Mutant related to the mutation of 5-hydroxylin transshipment gene，But except 5-hydroxyline，Maybe other endogenous mental active substances work on the dimensions of pleasure，Including social neurotipides oxytocin and antidic urinary hormones，and sex hormone testosterone and estrogen。Research Discovery，Acute secretion of oxytocin in men，The ability to help improve their emotional state from facial expressions。Testosterone is related to hostile emotions，Existing evidence indicates，High -level testosterone is related to the reduction of pleasant humanity。The ratio of the length of bet365 best casino games the ring finger to the index finger is a sign of the testosterone before childbirth，It is also confirmed that it is negatively related to pleasant people。

　　Responsibility dimension

Responsibility seems to reflect the tendency of maintaining the stability of the individual's internal motivation，This up -to -bottom motivation control of the organization is necessary for humans who have the ability to set long -term goals，Because these long -term goals may conflict with the current interests。Responsibility can represent the ability and tendency to restrict the impulse in front of the eyes due to the pursuit of long -term goals，It is also the purest manifestation of this ability and tendency。Research Discovery，Impulses seeking and similar traits，related to high-level dopamine functions and 5-hydroxylidin function，Low 5-hydroxyline is related to the lack of control or suppression。5-hydroxyline and control and inhibit the relationship，Together with 5-hydroxyline is consistent with diligence。Another biological factors of due diligence are glucose metabolism。Glucose is the basic energy source of the brain，Research indicates，Blood glucose is consumed by self -controlling behavior，The degree of this consumption indicates the failure of self -control。Individuals that provide sufficient and stable glucose supply to the brain through metabolism，Score higher on the duty of responsibility。Individual differences in glucose metabolism are proven to be related to duty，In the process of consuming glucose in the brain system to promote self -control,，The frontal leaf cortex is likely to participate in it，Because the forehead cortex plays a core role in planning and active control behavior，And its glucose consumption is relatively high。A functional magnetic resonance imaging research display，The brain activity of the prefrontal leaf cortex in the reaction inhibitory mission is positively correlated with a survey on diligence。

　　Open dimension

From the perspective of psychological biology，Openness may be the minimum dimension of research in the five personality models。But，Openness is the only trait that is positively related to intelligence in the five personality models，It is also the only five bet365 best casino games personality traits related to a series of work memory and cognitive control test results，Study on nerve imaging and brain injury The openness is that openness is an indicator for the function of the frontal frontal cortex function。Pay attention to the network，Always related to the ability of fluid intelligence and solving new problems。Therefore，About intelligence、Study of neurological research on work memory and attention may help identify open neurological bases。Dopamine may be related to openness，It can effectively regulate the function of the outer frontal leaf cortex，and through the genome、Pharmacological operation and neural imaging and fluid intelligence、The individual differences in work memory are linked。Research Discovery，Openness and intelligence are just different aspects in the field of personality。Fluid intelligence and work memory seem to be mainly related to openness，and they can be described as intelligence。and crystal intelligence and language intelligence are not only related to intelligence，It is also related to the characteristics of artistic and contemplation，These specialty describes the openness of this field。A combination of openness and intelligence supports the "common" brain process of the two。

Personality Neuroscience is an emerging cross -disciplinary field that integrates personality psychology and neuroscience。Its research methods can potentially provide an interpretation model for personality psychology。In terms of basic psychological biology functions，Big Five Personality Model is a prospective general theoretical framework，Table characteristics with conceptual individual differences。The field of personality and neuroscience research currently has some unspeakable hypothesis，Personality traits and brain systems as the basis of these assumptions，All need to be clearer to promote the advancement of this field。Each character of the five personality models of the big five can be divided into two different aspects，They have different genetic foundations。Each level of each field also shows a unique genetic effect。Personality Neuroscience can explain many levels of characteristics at the level of personality level。

Personality Neuroscience Studies are still in the starting stage，Insufficient integration of personality model proposed by different researchers。Different bet365 best casino games personality models have roughly the same factor structure，In the future, the output results of several personality models can be transformed into a common language，Combining emerging technologies such as near -infrared spectrum imaging of neuroscience and traditional questionnaire survey methods，Multiple methods as much as possible to explore the association of personality traits and its biological basis。
