Testosterone measurement There are several possibilities as to what kind of biological samples should be used for the testosterone measurement. Plasma, saliva, urine are available and all have some strengths and weaknesses. The simple scheme of free—bioactive fraction of testosterone that should be assessed using salivary testosterone or plasma albumin and sex hormone binding globulin is not correct.
Bound testosterone has its effects on target tissues and it is not clear which of the potential biological liquids is robust against technical and biological variability.
One of the exotic possibilities is measurement of testosterone in the hair. The concentration in the hair might, however, be relevant as it integrates all the intra-individual variability of testosterone Dettenborn et al. Timing Testosterone undergoes several biorhythms. In some studies, even the best-known circadian rhythm is not taken into account. Implants that slowly release testosterone totally ignore daily variations that occur physiologically.
Other rhythms such as infradian cycles are completely forgotten when experiments are designed.
On the effects of testosterone on brain behavioral functions
But beyond cyclic variations, testosterone undergoes chaotic temporary changes that are usually described as noise. Although such research is lacking, it might be that it has some physiological role similarly to heart rhythm variability.
In addition, the timing of behavioral analyses is of importance. While within 30 min after administration, non-genomic effects are important, later genomic effects are expected to be the major mediator. But this does not have to be true. It is used in perception, visual-spatial attention, the processing of new information The main structures related to it are in the posterior parietal cortex, the lateral pulvinar, the hippocampus, and the anterior cingulate.
Allows us to direct our attention to the action. It regulated and controls the make complex cognitive tasks possible. This system makes up part of the anterior cingulate, the dorsolateral prefrontal cortex, the orbital-frontal cortex, the neostriatum, the suplemental motor area, and the ventral tegmental area.
Memory is a complex process that allows us to code, store, and recover information. If the attentional system doesn't work properly, we won't be as efficient in doing such tasks. If we don't pay attention to something, we cannot code, store, or recover this information.
In order to understand memory, we can classify it according to two criteria: Short-term passive storage system that allows us to work with information. For example, when we try to remember a telephone number before writing it on a piece of paper. References memories that may be consciously evoked. For example, where did we go on vacation last year? When did I graduate? When did I get married? This memory references what we've learned and our general knowledge of the world.
What is the capital of France? What is a square root? The medial temporal lobe and the diencephalon are the structures associated with this kind of memory. Non-declarative or implicit memory: References subconscious memories and some skills like riding a bike or ice-skating. The neocortex, the amygdala when emotions are involvedthe striatum, and the reflex arcs. We also have to keep in mind that the storage zones are in the temporal lobes, but the more strategic components are more related to the frontal lobes.
Executive functions are the most complex cognitive functions.
