BrainA brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons.
Human brainThe human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head.
Computational neuroscienceComputational neuroscience (also known as theoretical neuroscience or mathematical neuroscience) is a branch of neuroscience which employs mathematical models, computer simulations, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system. Computational neuroscience employs computational simulations to validate and solve mathematical models, and so can be seen as a sub-field of theoretical neuroscience; however, the two fields are often synonymous.
Romani peopleThe Romani, also spelled Romany or Rromani (ˈroʊməni or ˈrɒməni ), colloquially known as the Roma (: Rom), are an Indo-Aryan ethnic group who traditionally lived a nomadic, itinerant lifestyle. Linguistic and genetic evidence suggests that the Romani originated in the Indian subcontinent; in particular, the region of present-day Rajasthan. Their subsequent westward migration, possibly in waves, is now believed by historians to have occurred around 1000 CE.
Romani diasporaThe Romani people have several distinct populations, the largest being the Roma and the Calé, who reached Anatolia and the Balkans in the early 12th century, from a migration out of the Indian subcontinent beginning about 1st century – 2nd century AD. They settled in the areas of present-day Turkey, Greece, Serbia, Romania, Croatia, Moldova, Bulgaria, North Macedonia, Hungary, Albania, Kosovo, Bosnia and Herzegovina, Czech Republic, Slovenia and Slovakia, by order of volume, and Spain.
