What is the function of neurons in the brain?
The function of neurons in the brain is to process the internal and external entry received by the human body and ensure that the body continues to function properly. Individual neurons do not perform this function themselves, but the team of neurons working in the brain processes all stimuli coming from the inside and outside the body. Each neuron is an electrically exciting cell that transmits information to other neurons through chemical and electrical signals, and combined signals of neural groups in the brain allow carefully processed input responses.
When transferring signals, they rely on chemical and electrical data. Chemical signals are transmitted between neurons using neurotransmitters, which are small molecules that are carried from one neuron to another to continue their way. Electrical signals transmit data through the neurons themselves and travel from their origin in receivers called Dendrity until it has a chemical signaling at the end of the neuron. Many human disorders, nOther treatable and other debilitating, the result of errors in the transmission of electric or chemical signal between neurons in the brain.
All neurons in the brain are structurally similar, although different areas of the brain may have slightly different neuronal structures. Different structures give specific groups of neurons specific abilities and therefore different areas of the brain are specialized for different tasks. For example, the visual bark processes the eye inlet and the motor cortex processes movement. Each area of the brain is specialized in something and different areas of the brain often cooperate in routine tasks. In popular culture, there is a common misconception that people use only a small part of their brains, but in fact it is not true; The whole is constantly used daily.
Science has shown that neurons in the brain are much more adaptable than it was previously believed. For many years it has been believed that if the brain was damaged that f had occurredUnkce affected neurons would be permanently and irreversibly lost. Mnoho novějších studií ukázalo, že mozek vykazuje schopnost přesměrovat funkce, i když alternativní nervové dráhy, známé jako plasticita. Někteří lidé s poškozením vizuálních center mozku mohou stále vidět a někteří lidé s polovinou jejich mozků mohou fungovat relativně normálně.
