17 questions about neuroscience and their answers

Neuroscience is, in many ways, the basis of current psychology, which helps to structure theories and models that attempt to explain behavior and mental processes. Knowing how the nervous system works, and in particular our brain, allows us to raise hypotheses that we can test through research.

In this article you will find a collection of questions on neuroscience, Useful for reviewing the basics related to this area of ​​knowledge.

    17 questions about neuroscience

    These questions are not sorted in order according to a precise criterion, do not hesitate to start answering them wherever you want.

    1. What is brain plasticity?

    It is the brain’s ability to move away from new situations, If they have to do with changes in the environment (for example, going to live in another ecosystem) or if they have to do with changes in their own morphology (for example, due to injuries).

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

      These are glial cells that perform a variety of functions, including supporting neurons.

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

      Memories based on memorizing one’s own bodily movements, as well as those which are fundamentally the emotional burden of an experience, do not compete in the hippocampus, and are instead related to the amygdala and basal ganglia.

      4. What is the difference between hormones and neurotransmitters?

      Neurotransmitters are basically because they act as mechanisms for transmitting information between neuronsAnd 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 questions in neuroscience that relies 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 about 80 billion neurons.

      6. At what stage of life do brain neurons have more connections with others?

      It happens during the first months of life. Soon after, using a genetically programmed pruning system, many of these synaptic connections disappear.

      7. Which brain structures are most closely related to emotions?

      these correspond to the limbic system: The hypothalamus, amygdala, septum, fornix and cingulate gyrus.

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

      This is a tricky question, because 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 the two hemispheres of the brain, move the axons of neurons from side to side.

      10. What does the so-called “white matter” of the nervous system owe its color to?

      What gives it this characteristic color is essentially the myelin, which covers the axons of neurons. to make nerve impulses travel through them faster.

      11. Why do psychopharmaceuticals have side effects?

      These effects appear, mainly, because the molecules released by these compounds reach areas of the body that are not interested in affecting 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 technique for studying nerve activity is not used to predict people’s behavior well, although in some cases they can help provide information based on probability.

      13. What is Penfield’s homunculus?

      It is a representation of the brain map in which are found the groups of neurons that process the tactile sensations of each of these zones, and those which control the movement orders to the muscles of these areas.

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

        This is the occipital lobe, located at the back of the brain. It is dedicated to working with the “raw” data entering through the visual system.

        15. Are there pain sensors in the brain?

        No, and that’s why it’s possible for small parts of your nerve tissue to break apart without any discomfort being noticed.

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

        In humans, never, or at least during your lifetime. Even while sleeping, there are connections that are strengthened and others that are weakened.

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

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