    The human brain has some 8.6 x 10 10 (eighty six billion) neurons. [31] [32] Each neuron has on average 7,000 synaptic connections to other neurons. It has been estimated that the brain of a three-year-old child has about 10 15 synapses (1 quadrillion).

    English: Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.

  4. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The human brain can feature in science fiction, with themes such as brain transplants and cyborgs (beings with features like partly artificial brains). [225] The 1942 science-fiction book (adapted three times for the cinema) Donovan's Brain tells the tale of an isolated brain kept alive in vitro , gradually taking over the personality of the ...

    The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1] There are many types of neuron, and several types of glial cell.

  6. Connectome - Wikipedia

    en.wikipedia.org/wiki/Connectome

    A connectome is constructed by tracing the neuron in a nervous system and mapping where neurons are connected through synapses. The significance of the connectome stems from the realization that the structure and function of the human brain are intricately linked, through multiple levels and modes of brain connectivity.

    Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord.

  8. Brain - Wikipedia

    en.wikipedia.org/wiki/Brain

    The human brain has been estimated to contain approximately 100 trillion synapses; [12] even the brain of a fruit fly contains several million. [13] The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal ...

    This development section covers changes in brain structure over time. It includes both the normal development of the human brain from infant to adult and genetic and evolutionary changes over many generations. Neural development in humans; Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc.
