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.
Degrees of freedom problemIn neuroscience and motor control , the degrees of freedom problem or motor equivalence problem states that there are multiple ways for humans or animals to perform a movement in order to achieve the same goal. In other words, under normal circumstances, no simple one-to-one correspondence exists between a motor problem (or task) and a motor solution to the problem.
Child development stagesChild development stages are the theoretical milestones of child development, some of which are asserted in nativist theories. This article discusses the most widely accepted developmental stages in children. There exists a wide variation in terms of what is considered "normal", caused by variations in genetic, cognitive, physical, family, cultural, nutritional, educational, and environmental factors. Many children reach some or most of these milestones at different times from the norm.
