A connectome (/ k ə ˈ n ɛ k t oʊ m /) is a comprehensive map of neural connections in the brain, and may be thought of as its "wiring diagram". [2] An organism's nervous system is made up of neurons which communicate through synapses. A connectome is constructed by tracing the neuron in a nervous system and mapping where neurons are ...
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.
Schematic diagram of the primate LGN. The parvocellular neurons of the visual system receive their input from midget cells, a type of retinal ganglion cell, whose axons comprise the optic tract. These synapses occur in one of the four dorsal parvocellular layers of the lateral geniculate nucleus.

The pathway helps to connect parts of the brain or nervous system that are distant, and are typically known and seen as white matter. In the vision pathway, visual information leaves the eye with the help of the optic nerve. Axons partially cross in the middle of the optic chiasm.
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. They are located in the brain and spinal cord and help to receive and conduct impulses.

The two main neuronal classes in the cerebral cortex are excitatory projection neurons (around 70-80%) and inhibitory interneurons (around 20–30%). [2] Neurons are often grouped into a cluster known as a nucleus where they usually have roughly similar connections and functions. [3] Nuclei are connected to other nuclei by tracts of white matter.
