I lilo 'o ka forebrain a me ka mea i hana' ia hanaʻia

Ke forebrain o ka loa rostral lala o ka'emi ko kahua. Ua ninoieo o ka cerebral hemispheres (ka cortex) a me ka basal ganglia. Ka hope, i loko o ka cortex, Aia ma waena o ka frontal māhele o ka lolo a me ka diencephalon. I ka haku mele 'ana o kēia mau nukelea hale a loaʻa ka caudate nucleus, i ka iwi, a pu lakou i ke kino striatum. Kona inoa ka mea, ua loaa i ka hopena o ka alternation o oho mea, haku o nā aʻalolo keena, a keʻokeʻo. Mau kumu, pu me cerebral haikea mea poepoe, i kapaia o pallidum palapala striopallidarnoy nenoaiu. He'ōnaehana ma mammals, a me loko o kānaka, i ke kumu nui nukelea manaʻo, a ua komo i loko o ka keʻano o ka hanaʻana o ka Hawaii hana, a me kekahi mau hana.

I ka haku mele 'ana o ka basal ganglia i subcortical nuclei ua loa like ke kelepona hele haku mele' ana. Ke globus pallidus mea nui a me ka uuku neurons. Striatum aeea i ka like hui. No ka neurons striopallidarnoy nenoai hele impulses, mai ka cerebral cortex, thalamus, anei i nuclei.

He aha e na mana subcortical nuclei?

Kernel striopallidarnoy nenoai limahana ma Hawaii ōhumu a me Hawaii hope. Stimulation o ka caudate nucleus, ua huli poo stereotypical ano, a lulu ka neʻe 'ana o na mea kaua a me forelimbs holoholona. Ma ke kaʻina hana o këia ka striatum, ka mea, ua loaʻa i ka mea loaʻa i ke kūlana i loko o ka keʻano o ka hanaʻana o memorizing ka neʻe 'ana. Ae hookaawale i kēia 'ole aʻe i ka keʻano o ka hanaʻana o ka iaiyoe a me ka hoʻonaʻauao. Striopallidarnoy'ōnaehana ka lawe inhibitory 'ole ma ka locomotor hope a me kona mea naʻau eiiiiiaiou, e like me keʻano pākīkē naoh.

Ka wauke o ka cerebral hemispheres

Ke forebrain kikowaena hoʻonaʻauao, a ua kapaia ka pńpa. Ua Ua noʻonoʻo pono i ka muli kahua o ka lolo. Morphologically, ka cortex ua haku o ka oho mea e uhi i ka pau lolo a me ka mai i ka nui ele ele ku i ka pā lehulehu a me ka convolutions. Ke oho mea ninoieo o ka nui helu o nā aʻalolo keena. Aie a hiki i keia i ka helu o ka synaptic pili 'o Randy mea nui loa, ka mea, ua hoakaka pūnaewele a me ka aaioee o ka' ike i loaa mai. Ma ke kumu o ka helehelena a me ka evolution, kaʻawale kahiko, kahiko, a me ka hou pńpa. Iloko o ka evolution o ka mammalian neocortex ulu oi loa aku hoi koke. Makamua wauke i loko o kona haku mele 'ana i ka olfactory pu u kukui a me ka apana, i ka olfactory tubercles. Ka 'ole o ka mea kahiko hapa o cingulate gyrus, amygdala a me hippocampal gyrus. Ke koena wahi e pili ana i ka neocortex.

ʻO nā aʻalolo keena o ka cerebral cortex e hoonohonoho i ka papa a me ka pololei oe ano, i loko o ka 'ole ho okumu iʻeono papa.

1st - kapaia hakakino, i hana plexus nā aʻalolo olona, a komo i ka palena iki helu o nā aʻalolo keena.

2nd - kapaia mawaho grainy. Ua ninoieo ec neurons liilii, o kekahi ano, like i ka mānoanoa.

Akolu - Ua haku o pyramidal neurons.

4th - maloko granular, e like me ka mawaho, ahu iho, oia no ka poe liilii, neurons.

5th - kekahi mau Betz aeee (kanaka nunui pyramidal aeee). Keʻano o ka hanaʻana o kēia mau aeee (axons) e hana i ka pyramidal'āpana, a hiki i ka caudal'āpana, a hele i loko o ke alo aa o ka spinal kaula.

6th - multiforme ninoieo o neurons triangular a me ka fusiform.

ʻOiai ka neural hoʻolālā o ka cortex mai ka hailona no ka hana, he oi piha study ka mea, hoike mai ka oko ao eʻikea au i loko o ka olona, ka nui a me ka helu o ka keena a me kā lākou mau ai manamana ai detritus. Ma këia kanaka lolo cortex palapala i hoomakaukauia, i nā wahi 11 a me 52 o ke kula.

ʻO wau nō ke kuleana o ka mea forebrain?

Loa pinepine kahiko a me ka 'oi wauke hui. Ka mea, nāna i hana i ka olfactory lolo. Ke forebrain mea i kuleana no ka nastorazhivanie a me ka hoolohe, i ka hana mahiʻai ma autonomic reactions. Ka'ōnaehana mea i loko o ke kahua o ka pii hana a me Emotions kauwahi. Ma holoholona ho okolohua, ka wā ae hookaawale kahiko wauke hōʻike 'ole pili i ka digestive'ōnaehana: a mama, moni' ia, peristalsis. Ua mea hoi o keʻano ukiuki i ka tonsils ke kumu o ka loli ma ka hana ana i na nā loko (hakuʻala, uterus, bladder). Kekahi mau mea o ka cortex e komo i loko o ke kaʻina hana o ka memorizing.

Together ka hypothalamus, ka limbic wahi, a me ka forebrain (kahiko a me ka elemakule wauke) hana i ka limbic'ōnaehana, i malama homeostasis, a hōʻoiaʻiʻo i ka malama ana o na? Ueo.
