What is Neuroscience definition/concept

Neuroscience is a scientific discipline that spans many areas and, for this reason, the term is often used in the plural. Neuroscientists research several aspects that make up the nervous system : its structure , functions, pathologies and molecular bases. Also, this discipline analyzes the existing interactions between the different dimensions of the human brain , since all of them serve to know the biological foundations of conduct .

The structure and functions of the Nervous System

From a structural point of view, neuroscientists focus on the study of the lobes that make up the brain. There are three lobes: prefrontal, occipital and temporal. Each one is responsible for different brain functions.

In addition to the lobes, the nervous system also contains a number of organs, such as the hippocampus, hypothalamus, and the olfactory bulb. Some functions, such as olfactory or cognitive, require the intervention of various brain structures. Neuroscience

The molecular bases of the brain

Neurochemical and hormonal changes occur in the nervous system. And these changes are part of the molecular basis. In this way, neuroscientists can study chemical reactions related to motivation or depression situations . Depressed people often have some kind of deficit in the chemical reactions that affect neurotransmitters.

Pathologies such as Alzheimer’s or Schizophrenia are also studied in neuroscience.

Certain mental alterations are understood only through the analysis of brain structures and neurochemical activity. In the case of Alzheimer ‘s disease there is a deficit of acetylcholine. In schizophrenia, on the other hand, there are a series of chemical alterations and the most significant are related to dopamine, norepinephrine and serotonin, chemical substances that facilitate the neuronal connection.

Neuroscience and other related disciplines

In recent years, knowledge of the brain has been projected into all sorts of fields. In the business area there is neuromarketing and in the world of mental relaxation a new technique stands out : mindfulness (mindfulness). Neuroscience
