As it will be seen later on, the knowledge of this phenomenon is very important, for clinical and therapeutic reasons.
Back to the main page of the article. Amygdala A little almond shaped structure, deep inside the antero-inferior region of the temporal lobe, connects with the hippocampus, the septal nuclei, the prefrontal area and the medial dorsal nucleus of the thalamus.
Hippocampus Is particularly involved with memory phenomena, specially with the formation of long-term memory the one that, sometimes, lasts forever. Both are important connecting pathways of the limbic system. Thalamus Lesion or stimulation of the medial dorsal and anterior nuclei of the thalamus are associated with changes in emotional reactivity.
Hypothalamus This structure has ample connections with the other prosencephalic areas and the mesencephalus. It is located in the medial side of the brain between the cingulate sulcus and the corpus callosum principal fiber bundle connecting the two cerebral hemispheres. There is still much to be learned about this gyrus, but it is already known that its frontal part coordinates smells and sights with pleasant memories of previous emotions. This region also participates in the emotional reaction to pain and in the regulation of aggressive behaviour.
Wild animals, submitted to the ablation of the cingulate gyrus cingulectomy , become totally tamed. The cutting of a single bundle of this gyrus cingulotomy reduces pre-existent depression and anxiety levels, by interrupting neural communication across the Papez's circuit. The brainstem is the region responsible for the "emotional reactions", indeed, they are just reflex answers of inferior vertebrates, like reptiles and amphibians. The involved structures are the reticular formation, and the locus coeruleus, a concentrated mass of nor-epinephrine secreting neurons.
It is important to stress that, even in humans, these primitive structures remain active, not only as alerting mechanisms, vital for survival, but in the maintenance of the sleep-awake cycle.
In the ventral tegmental area , located in the mesencephalic part of the brain stem, there is a compact group of dopamine-secreting neurons whose axons end in the nucleus accumbens mesolimbic dopaminergic pathway.
The spontaneous firing or the electrical stimulation of neurons belonging to that region produce pleasurable sensations, some of them similar to orgasm. Many people who, for a genetic error, have a reduction of D2 dopamine receptors in the accumbens nucleus, become, sooner or later, incapable to obtain gratification from the common pleasures of life.
Thus, they seek atypical and noxious "pleasurable" alternatives, like alcoholism, cocaine addiction, impulsive gambling and compulsion for sweet foods.
Certain brainstem structures, like the nuclei of the cranial nerves, stimulated by impulses coming from the cortex and the striatum a subcortical formation , are responsible for the physiognomic: The septal region lies anteriorly to the thalamus.
Inside it, one finds the centers of orgasm four for women and one for men. This area has been associated with different kinds of pleasant sensations, mainly those related to sexual experiences.
This area comprises the entire non-motor anterior region of the frontal lobe. It underwent a great deal of development during the evolution of mammals.
It is specially large in man and in some species of dolphins. It does not belong to the traditional limbic circuit, but its intense bi-directional connections with thalamus, amygdala and other subcortical structures, account for the important role it plays in the genesis and, specially, in the expression of affective states. When the pre-frontal cortex suffers a lesion, the subject looses his sense of social responsibility as well as the capacity for concentration and abstraction.
The cingulate cortex is a part of the "grand lobe limbique" of Broca that consisted in addition to the olfactory part, which is no more considered there today of a superior cingulate part, supracallosal; and an inferior hippocampic part, infracallosal. The limbic lobe was separated from the remainder of the cortex by Broca for two reasons: Since the parasagittal gyrification is observed in non-primate species, the limbic lobe was thus declared to be "bestial". As with other parts of the cortex, there have been and continue to be discrepancies concerning boundaries and naming.
Brodmann , a student of Cécile Vogt-Mugnier and Oskar Vogt , who worked on Cercopithecus and not much in human [Bailey and von Bonin] , elaborated a system of numeration that unfortunately had no typological logic 1, 2 and 3 are sensory, 4 is motor, 5 is parietal, 6 is premotor and 7 is again parietal!
Area 25 was even not placed by him in the same place in the human brain. Area 24 anterior was distinguished from 23 posterior on the basis that it was agranular. More recently, the typographical von Economo's system was adopted by Bailey and von Bonin. Simple typographical naming should be preferred, for evident heuristic purposes.
