V\u011bdci zjistili, \u017ee krysy, stejn\u011b jako lid\u00e9, mohou za\u017e\u00edvat l\u00edtost. Toto zji\u0161t\u011bn\u00ed zpochyb\u0148uje dlouholet\u00e9 p\u0159esv\u011bd\u010den\u00ed, \u017ee l\u00edtost je jedine\u010dn\u011b lidsk\u00e1 emoce.<\/p>\n\n

N\u00e1vrh studie a metodologie<\/h2>\n\n

V\u011bdci pe\u010dliv\u011b sledovali mozkovou aktivitu \u010dty\u0159 krys pomoc\u00ed elektrod. Zam\u011b\u0159ili se na dv\u011b oblasti mozku, kter\u00e9 jsou kl\u00ed\u010dov\u00e9 pro rozhodov\u00e1n\u00ed. Krysy byly pot\u00e9 um\u00edst\u011bny do slo\u017eit\u00e9ho bludi\u0161t\u011b na jednu hodinu.<\/p>\n\n

Bludi\u0161t\u011b se skl\u00e1dalo z centr\u00e1ln\u00edho kruhu se \u010dty\u0159mi paprsky, kter\u00e9 se \u0161\u00ed\u0159ily ven. Na konci t\u0159\u00ed paprsk\u016f byly pamlsky s p\u0159\u00edchut\u00ed ban\u00e1nu, t\u0159e\u0161n\u011b nebo \u010dokol\u00e1dy. \u010ctvrt\u00fd paprsek vedl k nechutn\u00e9mu j\u00eddlu. Zvuk t\u00f3nu se ozval, kdy\u017e krysa dos\u00e1hla paprsku, co\u017e nazna\u010dovalo \u010dekac\u00ed dobu na pamlsek (1 a\u017e 45 sekund).<\/p>\n\n

L\u00edtostiv\u00e9 chov\u00e1n\u00ed pozorov\u00e1no<\/h2>\n\n

Krysy st\u00e1ly p\u0159ed volbou: po\u010dkat na pamlsek nebo p\u0159ej\u00edt k dal\u0161\u00edmu paprsku v nad\u011bji na krat\u0161\u00ed \u010dek\u00e1n\u00ed. Kdy\u017e krysy u\u010dinily \u0161patn\u00e9 rozhodnut\u00ed, nap\u0159\u00edklad opustily jednu pochoutku pro del\u0161\u00ed \u010dek\u00e1n\u00ed, projevily viditeln\u00e9 zn\u00e1mky l\u00edtosti.<\/p>\n\n

Neuron\u00e1ln\u00ed d\u016fkazy l\u00edtosti<\/h2>\n\n

V\u011bdci sledovali chu\u0165 j\u00eddla, na kterou krysy myslely, na z\u00e1klad\u011b aktivovan\u00fdch nervov\u00fdch drah v jejich mozc\u00edch. Krysy, kter\u00e9 litovaly sv\u00e9ho v\u00fdb\u011bru, se zam\u011b\u0159ily na konkr\u00e9tn\u00ed chu\u0165, kterou pro\u0161vihly. Tato neuron\u00e1ln\u00ed aktivita poskytla jasn\u00e9 d\u016fkazy l\u00edtostiv\u00e9ho my\u0161len\u00ed.<\/p>\n\n

P\u0159esto\u017ee byly v minulosti p\u0159ehl\u00ed\u017eeny, krysy maj\u00ed p\u016fsobivou kognitivn\u00ed zdatnost. Tato studie poskytuje neurologick\u00e9 d\u016fkazy o jejich l\u00edtostiv\u00e9m chov\u00e1n\u00ed, emoci, o kter\u00e9 se d\u0159\u00edve v\u011b\u0159ilo, \u017ee je exkluzivn\u00ed pro lidi.<\/p>\n\n

Role kognitivn\u00ed zdatnosti v l\u00edtosti<\/h3>\n\n

Kognitivn\u00ed funkce a l\u00edtost<\/h2>\n\n

L\u00edtost zahrnuje p\u0159em\u00fd\u0161len\u00ed o minul\u00fdch rozhodnut\u00edch a hodnocen\u00ed promarn\u011bn\u00fdch p\u0159\u00edle\u017eitost\u00ed. To vy\u017eaduje pokro\u010dil\u00e9 kognitivn\u00ed schopnosti, v\u010detn\u011b pam\u011bti, rozhodov\u00e1n\u00ed a emocion\u00e1ln\u00edho zpracov\u00e1n\u00ed. Schopnost krys litovat nazna\u010duje, \u017ee tyto kognitivn\u00ed schopnosti vlastn\u00ed ve v\u00fdznamn\u00e9 m\u00ed\u0159e.<\/p>\n\n

D\u016fsledky pro studium lidsk\u00fdch emoc\u00ed<\/h2>\n\n

Krysy se uk\u00e1zaly jako cenn\u00fd model pro studium lidsk\u00fdch emocion\u00e1ln\u00edch reakc\u00ed. Je to proto, \u017ee sd\u00edlej\u00ed mnoho mozkov\u00fdch struktur a kognitivn\u00edch proces\u016f s lidmi. Objev l\u00edtosti u krys otev\u00edr\u00e1 nov\u00e9 cesty pro v\u00fdzkum neurologick\u00e9ho z\u00e1kladu lidsk\u00fdch emoc\u00ed.<\/p>\n\n

Evolu\u010dn\u00ed perspektiva<\/h2>\n\n

L\u00edtost se mohla vyvinout jako adaptivn\u00ed mechanismus, kter\u00fd pom\u00e1h\u00e1 zv\u00ed\u0159at\u016fm \u010dinit informovan\u011bj\u0161\u00ed rozhodnut\u00ed v budoucnu. Pro\u017e\u00edv\u00e1n\u00edm l\u00edtosti se zv\u00ed\u0159ata mohou pou\u010dit ze sv\u00fdch chyb a vyhnout se jejich opakov\u00e1n\u00ed.<\/p>\n\n

Tato studie poskytuje z\u00e1klad pro dal\u0161\u00ed v\u00fdzkum l\u00edtosti u zv\u00ed\u0159at. Budouc\u00ed studie by mohly zkoumat v\u00fdvojovou trajektorii l\u00edtosti, jej\u00ed dopad na soci\u00e1ln\u00ed chov\u00e1n\u00ed a jej\u00ed potenci\u00e1ln\u00ed roli p\u0159i rozhodov\u00e1n\u00ed nap\u0159\u00ed\u010d r\u016fzn\u00fdmi druhy.<\/p>\n\n
