Cerveauvignette|Cerveau d'un chimpanzé. Le cerveau est le principal organe du système nerveux des animaux bilatériens. Ce terme tient du langage courant (non scientifique) et chez les chordés, comme les humains, il peut désigner l'encéphale, ou uniquement une partie de l'encéphale, le prosencéphale (télencéphale + diencéphale), voire seulement le télencéphale. Néanmoins, dans cet article, le terme « cerveau » prend son sens le plus large. Le cerveau des chordés est situé dans la tête, protégé par le crâne chez les craniés, et son volume varie grandement d'une espèce à l'autre.
Object recognition (cognitive science)Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context. Neuropsychological evidence affirms that there are four specific stages identified in the process of object recognition.
Interprocedural optimizationInterprocedural optimization (IPO) is a collection of compiler techniques used in computer programming to improve performance in programs containing many frequently used functions of small or medium length. IPO differs from other compiler optimizations by analyzing the entire program as opposed to a single function or block of code. IPO seeks to reduce or eliminate duplicate calculations and inefficient use of memory and to simplify iterative sequences such as loops.
Biomarker (medicine)In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention." More generally a biomarker is anything that can be used as an indicator of a particular disease state or some other physiological state of an organism.
