Psychophysiological recording techniques

In this BIOLOGY video we will explain the "Psychophysiological recording techniques".

Psychophysiological recording techniques: neuroscience block. In these techniques we are going to record the activity of the nervous system or other parameters of the organism that are traditionally modified during the experimentation of certain emotions, states of sleep or, by establishing certain patterns of "normality" we can know when there is one of these variables that is escapes us. A typical example is the heart rate. It has approximate values ​​between 60 and 80 beats per minute. When things go down; bradycardia or up; tachycardia. Due to an increase in the number of beats per unit of time... at least we wonder if something is not happening and that is why we investigate what is behind it. This is one of several examples that we will look at. Let's start at the beginning: Techniques of recordpsychophysiological. All of them are going to use and have in common; or electrodes (which receive electrical information and which are on the surface of the body or the scalp) or use any other type of instrument that continues to remain in the surface. We do not enter the body. We do not invade. Everything is at surface level.

Another of the tests or techniques of psychophysiological record: electroencephalogram. This is going to receive is the electrical activity that generates the brain and cerebellum (the entire brain of general shape) and transforms it into a graphic or image that allows us to see the famous waves cerebral. This, for example, is very useful in cases of epilepsy (when a person has an epileptic seizure or is another type of seizure), the formation of consciousness and studying how we perceive. One way to study how we perceive is by using bite potential experiments. In these, some stimuli are passed at a certain time to the experimental subject and how brain activity changes is recorded. In order to understand what is behind this change, what areas and what ways.
