âWe are the laggard partner in this co-evolution.â âShe said that Newry's success is not through external help but through the energy of the people that âcaptured the imagination of the whole of Ireland and even cajoled the laggard politicians.ââ
One type of neuron called the Purkinje cell, found in the cerebellum, may have as many as one hundred thousand synapses.How big is a synapse? [ii]Synapses are very small. This narrow gap of extracellular space is approximately 20-40 nanometers (nm) wide. For an idea of scale, one inch is about 25.4 million nm long. The thickness of a single sheet of paper is about 100,000 nm.[iii]How many synapses are in the human brain?[iv][v]Current studies estimate that the average adult male human brain contains approximately 86 billion neurons.
The brain may be an even more powerful computer than before thought â microscopic branches of brain cells that were once thought to basically serve as mere wiring may actually behave as minicomputers, researchers say. The most powerful computer known is the brain. The human brain possesses about 100 billion neurons with roughly 1 quadrillion â 1 million billion â connections known as synapses wiring these cells together. Neurons each act like a relay station for electrical signals.
