Plasticita mozku: Schopnost mozku se m\u011bnit<\/h2>\n\n

Lidsk\u00fd mozek je neuv\u011b\u0159iteln\u011b slo\u017eit\u00fd org\u00e1n, kter\u00fd se neust\u00e1le m\u011bn\u00ed a p\u0159izp\u016fsobuje v reakci na na\u0161e zku\u0161enosti.

Proces “v\u00fdb\u011brov\u00e9ho \u0159\u00edzen\u00ed”<\/h2>\n\n

Abychom pochopili, pro\u010d mozek proch\u00e1z\u00ed t\u011bmito zm\u011bnami objemu, navrhli v\u011bdci teorii neuronov\u00e9ho pro\u0159ez\u00e1v\u00e1n\u00ed<\/strong>. Tato teorie nazna\u010duje, \u017ee kdy\u017e se u\u010d\u00edme n\u011bco nov\u00e9ho, mozek produkuje nadbytek nov\u00fdch neuron\u016f neboli mozkov\u00fdch bun\u011bk. Tyto nov\u00e9 neurony pak proch\u00e1zej\u00ed procesem “v\u00fdb\u011brov\u00e9ho \u0159\u00edzen\u00ed”, ve kter\u00e9m mozek vyhodnocuje jejich \u00fa\u010dinnost a funk\u010dnost.<\/p>\n\n

\u00da\u010dinn\u00e9 bu\u0148ky versus nadbyte\u010dn\u00e9 bu\u0148ky<\/h2>\n\n

B\u011bhem tohoto v\u00fdb\u011brov\u00e9ho \u0159\u00edzen\u00ed mozek identifikuje nej\u00fa\u010dinn\u011bj\u0161\u00ed neurony a ponech\u00e1 si je, zat\u00edmco ty m\u00e9n\u011b \u00fa\u010dinn\u00e9 odstran\u00ed.

Po\u010d\u00e1te\u010dn\u00ed zv\u011bt\u0161en\u00ed mozku b\u011bhem u\u010den\u00ed p\u0159edstavuje produkci nadbyte\u010dn\u00fdch neuron\u016f. Jakmile prob\u00edh\u00e1 proces pro\u0159ez\u00e1v\u00e1n\u00ed, mozek se zmen\u0161uje<\/strong> zp\u011bt na svou norm\u00e1ln\u00ed velikost nebo t\u00e9m\u011b\u0159 norm\u00e1ln\u00ed velikost.
