Shades of greenVarieties of the color green may differ in hue, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. The color defined as green in the RGB color model is the brightest green that can be reproduced on a computer screen, and is the color named green in X11.
Électroencéphalographie intracrânienneL'électroencéphalographie intracrânienne dite aussi intra-cérébrale, sous-durale, stéréotaxique (SEEG) est une méthode d'enregistrement de l'activité du cerveau au moyen d'électrodes implantées en profondeur sous la boîte crânienne utilisée notamment en neurologie, dans le diagnostic pré-chirurgical de l'épilepsie.
Interface neuronale directethumb|250px|Schéma d'une interface neuronale directe. Une interface neuronale directe - abrégée IND ou BCI ou encore ICM (interface cerveau-machine, ou encore interface cerveau-ordinateur) est une interface de communication directe entre un cerveau et un dispositif externe (un ordinateur, un système électronique...). Ces systèmes peuvent être conçus dans le but d'étudier le cerveau, d'assister, améliorer ou réparer des fonctions humaines de cognition ou d'action défaillantes. L'IND peut être unidirectionnelle ou bidirectionnelle.
N200 (neuroscience)The N200, or N2, is an event-related potential (ERP) component. An ERP can be monitored using a non-invasive electroencephalography (EEG) cap that is fitted over the scalp on human subjects. An EEG cap allows researchers and clinicians to monitor the minute electrical activity that reaches the surface of the scalp from post-synaptic potentials in neurons, which fluctuate in relation to cognitive processing. EEG provides millisecond-level temporal resolution and is therefore known as one of the most direct measures of covert mental operations in the brain.
NeurolinguistiqueNeurolinguistics is the study of neural mechanisms in the human brain that control the comprehension, production, and acquisition of language. As an interdisciplinary field, neurolinguistics draws methods and theories from fields such as neuroscience, linguistics, cognitive science, communication disorders and neuropsychology. Researchers are drawn to the field from a variety of backgrounds, bringing along a variety of experimental techniques as well as widely varying theoretical perspectives.
Rythme cérébralUn rythme cérébral (appelé aussi activité neuro-électrique) désigne l'oscillation électromagnétique émise par le cerveau des êtres humains, mais également de tout être vivant. Le cortex frontal qui permet la cognition, la logique et le raisonnement est composé de neurones qui sont reliés entre eux par des synapses permettant la neurotransmission. Mesurables en volt et en hertz, ces ondes sont de très faible amplitude : de l'ordre du microvolt (chez l'être humain), elles ne suivent pas toujours une sinusoïde régulière.
Target audienceA target audience is the intended audience or readership of a publication, advertisement, or other message catered specifically to said intended audience. In marketing and advertising, it is a particular group of consumer within the predetermined target market, identified as the targets or recipients for a particular advertisement or message. Businesses that have a wide target market will focus on a specific target audience for certain messages to send, such as The Body Shops Mother's Day advertisements, which were aimed at the children and spouses of women, rather than the whole market which would have included the women themselves.
Neural networkA neural network can refer to a neural circuit of biological neurons (sometimes also called a biological neural network), a network of artificial neurons or nodes in the case of an artificial neural network. Artificial neural networks are used for solving artificial intelligence (AI) problems; they model connections of biological neurons as weights between nodes. A positive weight reflects an excitatory connection, while negative values mean inhibitory connections. All inputs are modified by a weight and summed.
Cible (marketing)A target market, also known as serviceable obtainable market (SOM), is a group of customers within a business's serviceable available market at which a business aims its marketing efforts and resources. A target market is a subset of the total market for a product or service. The target market typically consists of consumers who exhibit similar characteristics (such as age, location, income or lifestyle) and are considered most likely to buy a business's market offerings or are likely to be the most profitable segments for the business to service by OCHOM Once the target market(s) have been identified, the business will normally tailor the marketing mix (4 Ps) with the needs and expectations of the target in mind.
Dissociation (psychologie)En psychologie, la dissociation est une . Ainsi, la prise en compte de la réalité et du vécu est inhibée (pensée, jugement, sentiment), de façon temporaire ou durable, pour supporter un traumatisme psychique. On oppose la dissociation à la psychose qui est une perte de contact avec la réalité, et on distingue plusieurs niveaux de dissociation : la dissociation primaire isole l’expérience, c'est la situation de stress post-traumatique ; la dissociation secondaire est une désintégration de l’expérience, avec un et un ; la dissociation tertiaire est la genèse d'États du Moi indépendants (voir trouble dissociatif de l'identité).
