Brain tumorA brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved.
Local field potentialLocal field potentials (LFP) are transient electrical signals generated in nervous and other tissues by the summed and synchronous electrical activity of the individual cells (e.g. neurons) in that tissue. LFP are "extracellular" signals, meaning that they are generated by transient imbalances in ion concentrations in the spaces outside the cells, that result from cellular electrical activity. LFP are 'local' because they are recorded by an electrode placed nearby the generating cells.
ConversationConversation is interactive communication between two or more people. The development of conversational skills and etiquette is an important part of socialization. The development of conversational skills in a new language is a frequent focus of language teaching and learning. Conversation analysis is a branch of sociology which studies the structure and organization of human interaction, with a more specific focus on conversational interaction.
Personal lifePersonal life is the course or state of an individual's life, especially when viewed as the sum of personal choices contributing to one's personal identity. Apart from hunter-gatherers, most pre-modern peoples' time was limited by the need to meet necessities such as food and shelter through subsistence farming; leisure time was scarce. People identified with their social role in their community and engaged in activities based on necessity rather than on personal choice. Privacy in such communities was rare.
Media studiesMedia studies is a discipline and field of study that deals with the content, history, and effects of various media; in particular, the mass media. Media Studies may draw on traditions from both the social sciences and the humanities, but mostly from its core disciplines of mass communication, communication, communication sciences, and communication studies.
Alphabetical orderAlphabetical order is a system whereby character strings are placed in order based on the position of the characters in the conventional ordering of an alphabet. It is one of the methods of collation. In mathematics, a lexicographical order is the generalization of the alphabetical order to other data types, such as sequences of numbers or other ordered mathematical objects. When applied to strings or sequences that may contain digits, numbers or more elaborate types of elements, in addition to alphabetical characters, the alphabetical order is generally called a lexicographical order.
Personal developmentPersonal development or self-improvement consists of activities that develop a person's capabilities and potential, build human capital, facilitate employability, enhance quality of life, and facilitate the realization of dreams and aspirations. Personal development may take place over the course of an individual's entire lifespan and is not limited to one stage of a person's life. It can include official and informal actions for developing others in roles such as teacher, guide, counselor, manager, coach, or mentor, and it is not restricted to self-help.
Gross anatomyGross anatomy is the study of anatomy at the visible or macroscopic level. The counterpart to gross anatomy is the field of histology, which studies microscopic anatomy. Gross anatomy of the human body or other animals seeks to understand the relationship between components of an organism in order to gain a greater appreciation of the roles of those components and their relationships in maintaining the functions of life. The study of gross anatomy can be performed on deceased organisms using dissection or on living organisms using medical imaging.
Historical materialismHistorical materialism is Karl Marx's theory of history. Marx locates historical change in the rise of class societies and the way humans labor together to make their livelihoods. For Marx and his lifetime collaborator, Friedrich Engels, the ultimate cause and moving power of historical events are to be found in the economic development of society and the social and political upheavals wrought by changes to the mode of production. It provides a challenge to the view that historical processes have come to a close and that capitalism is the end of history.
CollationCollation is the assembly of written information into a standard order. Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof. Collation is a fundamental element of most office filing systems, library catalogs, and reference books. Collation differs from classification in that the classes themselves are not necessarily ordered. However, even if the order of the classes is irrelevant, the identifiers of the classes may be members of an ordered set, allowing a sorting algorithm to arrange the items by class.
