How many neurons does the human brain have?


The human brain is made up of billions of cells called neurons, which are responsible for transmitting information throughout the body. The exact number of neurons in the human brain varies depending on the source, but it is generally estimated to be around 100 billion.

In addition to neurons, the brain also contains other types of cells, such as glial cells, which support and protect the neurons. The ratio of neurons to glial cells in the brain is estimated to be around 1:10, meaning that for every neuron in the brain, there are about 10 glial cells.

It's important to note that the number of neurons in the brain does not necessarily correlate with intelligence or cognitive ability. While the number of neurons can be an important factor in brain function, other factors, such as the strength of the connections between neurons (synapses) and the overall health of the brain, can also play a role in cognitive function
