Cultural Neuroscience
Cultural neuroscience is a field of research that focuses on the interrelation between a human's cultural environment and neurobiological systems. The field particularly incorporates ideas and perspectives from related domains like anthropology, psychology, and cognitive neuroscience to study sociocultural influences on human behaviors. Such impacts on behavior are often measured using various neuroimaging methods, through which cross-cultural variability in neural activity can be examined. Cultural neuroscientists study cultural variation in mental, neural and genomic processes as a means of articulating the bidirectional relationship of these processes and their emergent properties using a variety of methods. Researchers in cultural neuroscience are motivated by two fundamentally intriguing, yet still unanswered, questions on the origins of human nature and human diversity: how do cultural traits (e.g., values, beliefs, practices) shape neurobiology (e.g., genetic and neural ...

Cultural Variation
Cultural variation refers to the rich diversity in social practices that different cultures exhibit around the world. Cuisine and art all change from one culture to the next, but so do gender roles, economic systems, and social hierarchy among any number of other humanly organised behaviours. Cultural variation can be studied across cultures (for example, a cross-cultural study of ritual in Indonesia and Brazil) or across generations (for example, a comparison of Generation X and Generation Y) and is often a subject studied by anthropologists, sociologists and cultural theorists with subspecialties in the fields of economic anthropology, ethnomusicology, health sociology etc. In recent years, cultural variation has become a rich source of study in neuroanthropology, cultural neuroscience, and social neuroscience.

Self
In philosophy, the self is an individual's own being, knowledge, and values, and the relationship between these attributes. The first-person perspective distinguishes selfhood from personal identity. Whereas "identity" is (literally) sameness and may involve categorization and labeling, selfhood implies a first-person perspective and suggests potential uniqueness. Conversely, "person" is used as a third-person reference. Personal identity can be impaired in late-stage Alzheimer's disease and in other neurodegenerative diseases. Finally, the self is distinguishable from "others". Including the distinction between sameness and otherness, the self versus other is a research topic in contemporary philosophy and contemporary phenomenology (see also psychological phenomenology), psychology, psychiatry, neurology, and neuroscience. Although subjective experience is central to selfhood, the privacy of this experience is only one of many problems in the philosophy of self and ...

Major Depressive Disorder
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive depression (mood), low mood, low self-esteem, and anhedonia, loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this syndrome, symptom cluster under mood disorders in the 1980 version of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after low back pain, lower back pain. The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by family or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time o ...

Ventromedial Prefrontal Cortex
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. It also plays a role in the inhibition of emotional responses, and in the process of decision-making and self-control. It is also involved in the cognitive evaluation of morality. Anatomy While the ventromedial prefrontal cortex does not have a universally agreed on demarcation, in most sources, it is equivalent to the ventromedial reward network of Öngür and Price. This network includes Brodmann area 10, Brodmann area 14, Brodmann area 25, and Brodmann area 32, as well as portions of Brodmann area 11, Brodmann area 12, and Brodmann area 13. However, not all sources agree on the boundaries of the area. Different researchers use the term ''ventromed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Culture
Western culture, also known as Western civilization, European civilization, Occidental culture, Western society, or simply the West, refers to the Cultural heritage, internally diverse culture of the Western world. The term "Western" encompasses the social norms, ethical values, Tradition, traditional customs, belief systems, political systems, Cultural artifact, artifacts and technology, technologies primarily rooted in History of Europe, European and History of the Mediterranean region, Mediterranean histories. A broad concept, "Western culture" does not relate to a region with fixed members or geographical confines. It generally refers to the classical era cultures of Ancient Greece and Ancient Rome that expanded across the Mediterranean basin and Europe, and later circulated around the world predominantly through colonization and globalization. Historically, scholars have closely associated the idea of Western culture with the classical era of Greco-Roman antiquity. Howeve ...

Eastern Culture
Eastern culture, also known as Eastern civilization and historically as Oriental culture, is an umbrella term for the diverse cultural heritages of social norms, ethical values, traditional customs, belief systems, political systems, Cultural artifact, artifacts and technology, technologies of the Eastern world. While there is no singular and catch-all "Eastern culture", there are subgroups within it, such as countries within East Asia, Southeast Asia, or South Asia, as well as syncretism within these regions. These include the spread of Eastern religions such as Buddhism or Hinduism, the usage of Chinese characters or Brahmic scripts, language families, the fusion of cuisines, and traditions, among others. Terminology The East, as a Region, geographical area, is unclear and undefined. More often, the ideology of a state's inhabitants is what will be used to categorize it as an Eastern society. There is some disagreement about what nations should or should not be included in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superior Parietal Lobule
The superior parietal lobule is bounded in front by the upper part of the postcentral sulcus, but is usually connected with the postcentral gyrus above the end of the sulcus. The superior parietal lobule contains Brodmann's areas 5 and 7. Behind it is the lateral part of the parieto-occipital sulcus, around the end of which it is joined to the occipital lobe by a curved gyrus, the arcus parietooccipitalis. Below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus. The superior parietal lobule is involved with spatial orientation, and receives a great deal of visual input as well as sensory input from one's hand. In addition to spatial cognition and visual perception, it has also been associated with reasoning, working memory, and attention. It is also involved with other functions of the parietal lobe in general. There are major white matter pathway connections with the superior parietal lobule such as the Cingulum, SLF ...

Superior Temporal Gyri
The superior temporal gyrus (STG) is one of three (sometimes two) gyri in the temporal lobe of the human brain, which is located laterally to the head, situated somewhat above the external ear. The superior temporal gyrus is bounded by: * the lateral sulcus above; * the superior temporal sulcus (not always present or visible) below; * an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly. The superior temporal gyrus contains several important structures of the brain, including: * Brodmann areas 41 and 42, marking the location of the auditory cortex, the cortical region responsible for the sensation of sound; * Wernicke's area, Brodmann area 22, an important region for the processing of speech so that it can be understood as language. The superior temporal gyrus contains the auditory cortex, which is responsible for processing sounds. Specific sound frequencies map precisely onto the auditory cortex. This auditory (or tonotopic) map is similar to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Temporal Gyri
Middle temporal gyrus is a gyrus in the brain on the temporal lobe. It is located between the superior temporal gyrus and inferior temporal gyrus. It corresponds largely to Brodmann area 21. The middle temporal gyrus is bounded by: * the superior temporal sulcus above; * the inferior temporal sulcus below; * an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly. It has been connected with processes as different as contemplating distance, recognition of known faces, audio-visual emotional recognition, and accessing word meaning while reading. Some studies indicate that lesions of the posterior region of the middle temporal gyrus, in the left cerebral hemisphere, may result in alexia and agraphia for kanji are logographic Chinese characters, adapted from Chinese family of scripts, Chinese script, used in the writing of Japanese language, Japanese.

FMRI
Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast, discovered by Seiji Ogawa in 1990. This is a type of specialized brain and body scan used to map neural activity in the brain or spinal cord of humans or other animals by imaging the change in blood flow ( hemodynamic response) related to energy use by brain cells. Since the early 1990s, fMRI has come to dominate brain mapping research because it does not involve the use of injections, surgery, the ingestion of substances, or exposure to ionizing radiation. This measure is frequently corrupted by noise from various sources; hence, statistical procedures are used to extract the underlying signa ...

Precentral Gyrus
The precentral gyrus is a prominent gyrus on the surface of the posterior frontal lobe of the brain. It is the site of the primary motor cortex that in humans is cytoarchitecturally defined as Brodmann area 4. Structure The precentral gyrus lies in front of the postcentral gyrus - mostly on the lateral (convex) side of each cerebral hemisphere - from which it is separated by the central sulcus. Its anterior border is represented by the precentral sulcus, while inferiorly it borders to the lateral sulcus (Sylvian fissure). Medially, it is contiguous with the paracentral lobule. The internal pyramidal layer (layer V) of the precentral cortex contains giant (70-100 micrometers) pyramidal neurons called Betz cells, which send long axons to the contralateral motor nuclei of the cranial nerves and to the lower motor neurons in the ventral horn of the spinal cord. These axons form the corticospinal tract. The Betz cells along with their long axons are referred to as upper motor n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Parietal Lobule
The inferior parietal lobule (subparietal district) lies below the horizontal portion of the intraparietal sulcus, and behind the lower part of the postcentral sulcus. Also known as Geschwind's territory after Norman Geschwind, an American neurologist, who in the early 1960s recognised its importance. It is a part of the parietal lobe. Structure It is divided from rostral to caudal into two gyri: * One, the supramarginal gyrus ( BA 40), arches over the upturned end of the lateral fissure; it is continuous in front with the postcentral gyrus, and behind with the superior temporal gyrus. * The second, the angular gyrus ( BA 39), arches over the posterior end of the superior temporal sulcus, behind which it is continuous with the middle temporal gyrus. In males, the inferior parietal lobule is significantly more voluminous in the left hemisphere compared to the right. This extreme asymmetry is not present in females and this may contribute to cognitive differences between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
