17 questions about Neurosciences, and their answers.

Several questions about the brain and the Biological processes that govern it.

Neuroscience is, in many respects, the basis of current psychology, that which allows structuring the theories and models that try to explain behavior and mental processes. Knowing how the nervous system works, and in particular our brain, contributes to hypotheses that we can test through research.

In this article you will find a collection of neuroscience questionsuseful to review the basic concepts related to this field of knowledge.

17 questions about neuroscience

These questions are not arranged in order following a particular criterion, feel free to start answering them wherever you want.

1. What is brain plasticity?

It is the brain's the brain's ability to adapt to new situations, whether they have to do with changes in the environment (e.g., going to live in another ecosystem)whether they have to do with changes in the environment (e.g., going to live in another ecosystem) or changes in its own morphology (e.g., due to injury).

2. What is the most abundant cell type in the brain?

These are glial cells, which serve a variety of functions, including supporting neurons.

3. In what type of memory is the hippocampus not involved?

Memories based on memorization of one's own body movements, as well as those that are primarily the emotional charge of an experience, do not involve the hippocampus, and are rather related to the amygdala and basal ganglia.

4. What differentiates hormones from neurotransmitters?

Neurotransmitters are fundamentally neurotransmitters because they they act as mechanisms of information transmission between neurons, and as such travel through the synaptic space, exerting their effects rapidly.and as such they travel through the synaptic space, exerting their effects quickly. Hormones, on the other hand, travel through the blood, and take longer to reach a place where they trigger an effect. This is one of the neuroscience questions that are based on knowledge not limited to the nervous system.

5. Approximately how many neurons are there in the brain of an adult human being?

There are approximately 80 billion neurons.

6. At what stage of life do neurons in the brain have more connections with other neurons?

This occurs during the first months of life. Shortly thereafter, through a genetically programmed pruning system, many of these synaptic connections disappear.

7. Which brain structures are most related to emotions?

These correspond to the limbic systemThe hypothalamus, amygdala, septum, fornix and cingulate gyrus.

8. What kind of emotions and sensations do dopamine and GABBA produce?

This is a trick question, since each neurotransmitter does not have specific sensations associated with it. They can all have different effects, depending on the context in which they are used.

9. What is the corpus callosum?

It is the part of the brain that connects both hemispheres of the brain, making the axons of the neurons pass from one side to the other..

10. To what does the so-called "white matter" of the nervous system owe its color?

What gives it this characteristic color is, fundamentally, the myelin, which covers the axons of neurons to make the nerve impulses travel through them at a higher speed..

11. Why are there side effects of psychotropic drugs?

These effects appear, fundamentally, because the molecules released by these compounds reach areas of the organism that are not interested in affecting in order to solve the problem on which the treatment is focused.

12. Is it possible to know a person's personality from images of brain activity obtained with fMRI?

No, this type of techniques of study of the nervous activity does not serve to predict well the behavior of the persons, although in some cases they can help to contribute a little information about the personality of a person. can help to provide some information based on probability..

13. What is the Penfield homunculus?

It is a representation of the brain mapping in which the groups of neurons that process the tactile sensations of each of tactile sensations in each of these areas, and those that send movement commands to the muscles in these areas. to the muscles of these areas.

14. Which lobe of the brain is basically dedicated to the processing of visual information?

This is the occipital lobe, located at the back of the brain. It works with the "raw" data coming in through the visual system.

15. Are there pain detectors in the brain?

No, and therefore it is possible for small parts of its nerve tissue to break without any discomfort being felt.

16. When does the system of interconnections of the neurons of the brain stop changing?

In human beings, never, or at least not while we are alive. Even while sleeping, there are connections that are strengthened and others that are weakened..

17. Is the size of the brain in comparison to the rest of the body related to intelligence?

Yes, but only to a certain extent. When the differences in size are not very noticeable, this relationship is diluted.
