Question

How does the human brain work?

Answer 1

Hundreds of billions of nerve cells in your brain are organised in patterns that help you coordinate your thoughts, emotions, behaviour, movement, and sensations. Your brain is connected to the rest of your body by a complex highway system of nerves, allowing communication to happen in milliseconds. Consider how quickly you withdraw your hand away from a hot burner. While all of your brain's sections work together, each one is in charge of a specific function, such as controlling your heart rate or mood.

Complete answer:
The cerebellum is a wrinkled ball of tissue beneath and behind your brain. It helps coordinate movement by combining sensory input from the eyes, hearing, and muscles.
The brainstem is a tube that connects the brain to the spinal cord. It regulates critical activities such as heart rate, blood pressure, and breathing. This region is also crucial for sleeping.
Emotions and memories are controlled by deep brain structures. These structures are known as the limbic system, and they are found in pairs. Each component of this system is duplicated in the brain's opposing side.
The thalamus controls the flow of information between the spinal cord and the cerebral hemispheres.
Emotions are controlled by the hypothalamus. It also maintains your body's temperature and regulates important desires like eating and sleeping.
The hippocampus delivers memories to the proper areas of the cerebrum to be stored, and then recalls them as needed.
Aside from the nerves in your brain and spinal cord, the peripheral nervous system includes all nerves in your body. It serves as a conduit for communication between your brain and your limbs. When you touch a hot stove, for example, pain impulses travel from your finger to your brain in a fraction of a second. Your brain sends the muscles in your arm and hand to seize your finger off the hot burner in the same amount of time.
There are two types of branches that emerge from the cell bodies of nerve cells (neurons). Dendrites are the terminals of nerve cells that receive messages from other nerve cells. Outgoing signals from the cell body are carried by axons to other cells, such as a neighbouring neuron or muscle cell. Neurons are able to communicate efficiently and quickly because they are interconnected.
When a nerve cell (neuron) is triggered, electrical impulses are sent out to connect with other cells. The impulse travels to the tip of an axon within a neuron, causing the release of neurotransmitters, or chemical messengers.
Neurotransmitters travel between nerve cells via the synapse and connect to receptors on the receiving cell. As the impulse travels to its goal — a network of communication that allows you to move, think, feel, and communicate — this process repeats itself
from neuron to neuron.

Note:
The brain functions similarly to a large computer. It collects information from the senses and the body and processes it before sending messages back to the body. The brain, on the other hand, can accomplish much more than a machine: it is the brain that allows humans to think and feel emotions, and it is the source of human intellect.
