History of neuroscience. From the ancient Egyptian mummifications to 18th-century scientific research on "globules" and neurons, there is evidence of neuroscience practice throughout the early periods of history. The early civilizations lacked adequate means to obtain knowledge about the human brain. Their assumptions about the inner workings ...
The evolution of the brain refers to the progressive development and complexity of neural structures over millions of years, resulting in the diverse range of brain sizes and functions observed across different species today, particularly in vertebrates. The evolution of the brain has exhibited diverging adaptations within taxonomic classes ...
Origin and subsequent variation and development of neurons and neural tissues and organs. Not to be confused with Neuroevolution. For a theory of evolution in nervous systems, see Neural Darwinism. The evolution of nervous systemsdates back to the first development of nervous systemsin animals(or metazoans).
The peopling of India refers to the migration of Homo sapiens into the Indian subcontinent. Anatomically modern humans settled India in multiple waves of early migrations, over tens of millennia. [ 1 ] The first migrants came with the Coastal Migration / Southern Dispersal 65,000 years ago, whereafter complex migrations within South and ...
54527. Anatomical terms of neuroanatomy. [ edit on Wikidata] A neuron, neurone, [ 1 ] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system. Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of ...
India remained the world's only source of diamonds until the discovery of diamonds in Brazil in the 18th century. [223] [224] [225] Golconda served as an important centre for diamonds in central India. [226] Diamonds then were exported to other parts of the world, including Europe. [226] Early references to diamonds in India come from Sanskrit ...
In biology. In the context of biology, a neural network is a population of biological neurons chemically connected to each other by synapses. A given neuron can be connected to hundreds of thousands of synapses. [1] Each neuron sends and receives electrochemical signals called action potentials to its connected neighbors.
Evolutionary neuroscienceis the scientific study of the evolution of nervous systems. Evolutionary neuroscientists investigate the evolutionand natural historyof nervous systemstructure, functions and emergent properties. The field draws on concepts and findings from both neuroscienceand evolutionary biology.
