PROHABA.CO – The brain is a mosaic consisting of different types of cells, each of which has its own unique properties.
The most common brain cells are neurons and non-neuronal cells called glia.
The average adult human brain contains about 100 billion neurons, and an equal number if not more glia.
Although neurons are the most well-known brain cells, both neurons and glial cells are necessary for proper brain function.
In a fraction of a second, our brain can generate thoughts, feel sensations, and respond to everything we see.
Very rapid bursts of brain activity give us these abilities and allow us to do a variety of things and activities.
Reporting from Live Science, the first step in the process of conveying messages by brain cells is an action potential or electrical wave that is triggered in the nerve cells or neurons.
Neurons found in the brain, spinal cord, and throughout the body generally send messages in the same way.

Every time there is something we need to pay attention to, for example a certain sound, the receptors in the sense organs will activate nerve cells that go to the brain.
Small tunnels in the neuron membrane will open, allowing positively charged molecules or ions to enter the cell.
These charged particles ripple along the cell membrane, similar to the way electrons pass through wires in an electrical device.
These electrical signals travel from the cell membrane into its axon, which is a long, tail-like structure that protrudes from the cell body.
These axons are separated from the axons of the next nerve cell in the communication chain through gaps called synapses.
When these electrical impulses reach the end of the axon, the neuron releases chemicals called neurotransmitters into the synapse.
