Striatal

The striate cortex is part of a kind of nucleus called the striatum. This system could be viewed as an important site for storing and processing information in the brain. Cells called its neurons are found in large numbers in stripes in the middle of this formation, hence the name we know today.

The striatal nucleus of the brain was first discovered as a structure in 1859 by Italian psychiatrist Camillo Golgi. However, it was only during the 20th century and with the development of electron microscopes that it helped to discover that it was our present day basic element of our brain that the striatum was initially placed as a correlate of human intelligence. Hypotheses have been proposed that differences in intelligence responses reflect differences in striatal neurons between individuals. Moreover, some studies have suggested that the observed increase in the number of neurons in adulthood following the emergence of connections with the dorsal striatal nucleus is an important factor in intellectual development.

Functional studies of the striatum show that it plays an important role in many areas of behavior, including oral-sexual activity, rapid blinking, reward anticipation and motor coordination. This is consistent with scientists' understanding of this region in the physiology of movement and executive control. However, most work, especially recently, supports the view that the striatal and prestriate nuclei are part of the centralized executive system of the brain. These systems, some scientists argue, may replace the old idea of ​​striatal “half cells” as mediators of motor actions. Such theories emphasize functional similarities to control of the brainstem center as a whole. The striatum is also of particular importance for the study of Parkinson's disease. Because his death was associated with the known clinical and anatomical features of Parkinson's disease, it became a major study. Violent destruction of the striatal nucleus of the brain stem, caused by the introduction of toxic substances or genetic methods such as proviral gene insertion Increases intelligence
