Nā pūpili nerve e hoʻopili pū me nā lemu

ʻO Neuroplasticity

ʻOi ka hua'ōlelo neuroplasticity i lalo neuro no ka "neuron", nā pūnana nerve i loko o ko kākou lolo a me ka pūnaewele pale. lula ea ʻo ia no "loli, malleable, hiki ke hoʻololi ʻia." ʻO Neuroplasticity ke kuhikuhi i ka hiki i ka lolo ke hoʻololi i ka pane i ka ʻike. Hana ka lolo i kēia ma ka hoʻoikaika ʻana i nā pilina ma waena o kekahi mau pūnana nerve ʻoiai e hoʻonāwaliwali nei i nā pilina ma waena o kekahi. ʻO kēia kahi e mālama ai ka lolo i nā mea hoʻomanaʻo, aʻo, ʻike ʻole a hoʻololi i kahi ʻano loli. Mālama nā loina ʻelua i ka plasticity o ka lolo:

Ka mua, 'nāʻaʻaʻa nerve e puhi pū' ʻo ia hoʻi hiki i nā hanana ʻelua ke hoʻohui ikaika inā kū lākou i ka manawa like. ʻO kahi laʻana, kahi pēpē e hoʻopā nei i kahi kapuahi wela no ka manawa mua e hoʻonāuki i nā ʻāʻī nerve ʻelua e hana i nā kiʻi o kahi kapuahi-luna a me nā aʻa nerve e ʻike i ka ʻeha e ʻā ana. ʻO kēia mau hanana pili ʻelua i pili ʻole i pili paʻa ʻia i ka lolo ma o nā lālā nerve nerve. ʻO ka ʻike ʻana i nā kiʻi hoʻonāukiuki i ka moekolohe no ka manawa mua e hoʻokumu i kahi hoʻomanaʻo paʻa i ka lolo o kahi keiki a hoʻomaka i ka hoʻoheheʻe ʻana iā ia a me kāna anakuhi.

Ka lua, 'hoʻohana a nalowale iā ia' kūpono loa i kekahi mau puka aniani o ka hoʻomohala. ʻO ia ke kumu he maʻalahi loa ke aʻo i nā mākau a i ʻole nā ​​ʻano i kekahi mau makahiki. ʻAʻole mākou ʻike i nā gymnast 'Olumepika e hoʻomaka ana i ka makahiki 12 a i ʻole nā ​​mea hoʻokani pila mele e hoʻomaka ana i ka makahiki 25. ʻAʻole like me ka kamaliʻi, ua hoʻopili kahi ʻōpio nānā porn i nā mea kūwaho me kāna kaapuni kūlohelohe no ka pīhoihoi wahine. ʻO ka ʻōpio ka manawa e aʻo ai e pili ana i ka moekolohe. Hoʻopili nā pūnana nerve i ka heʻenalu ʻana i ka pūnaewele a me ke kaomi ʻana mai kahi a kahi hanana ahi me nā mea no ka pīhoihoi a me ka leʻaleʻa. Ke hana wale nei kāna ʻōnaehana limbic i kāna hana: hoʻopā i ke kapuahi = ʻeha; heʻe nalu pūnaewele pūnaewele = leʻaleʻa. Hoʻomaha ka hana i ka nāwaliwali i nā hui.

Nā Neurona

ʻO kā mākou lolo kahi ʻāpana o kahi ʻōnaehana hopohopo. Aia i loko o ka ʻōnaehana waena (CNS) a me ka ʻōnaehana nīnūnē ākea (PNS). Aia ka CNS i ka lolo a me ka iwi kuamoo. ʻO ia ke kikowaena hoʻomalu e loaʻa ana i ka ʻike sensory āpau mai ke kino āpau a laila hiki iā ia ke decode e hoʻoheheʻe i nā pane pili- e hoʻokokoke, huki a i ʻole 'ʻoiai ʻoe'. E pili ana i nā pane kikoʻī e hoʻouna i nā hōʻailona ma o ka PNS. No laila he kiʻi erotic, ʻala, hoʻopā, ʻono a hui huaʻōlelo paha e hoʻopau i nā ala hoʻonāukiuki mai ka lolo i nā genital ma o ka ʻōnaehana hopohopo i kahi hapa o kekona.

Aia ma ka lolo he 86 biliona aʻa aʻa paha a i ʻole nā ​​neurons. Loaʻa i ke neuron a i ʻole ke aʻalolo nerve kahi kino o ka pūnaewele i loaʻa ka nucleus me nā mea DNA. ʻO ka mea nui, loaʻa pū kekahi i nā protein i hoʻololi i ke ʻano ke hoʻololi lākou i ka hoʻokomo o ka ʻike mai kahi ʻē aʻe.

ʻOkoʻa nā newa liʻiliʻi mai nā pūʻokoʻa'ē aʻe ma ke kino no ka mea:

1. ʻO nā neurons kekahi mau māheleʻokoʻa i kapaʻia dendrites a axons. Lawe nā Dendrites i nā leka uila i ke kino o ke kino a lawe nā kumu i kaʻike mai ke kino o ke kino.
2. Kūkākūkā nā neurona i kekahi i kekahi ma kahi hana hana pono'ī.
3. Aia nā neurons i kahi hanana kūikawā (e like me nā synapses) a me nā kinikona (e like paha, neurotransmitters). E nānā ma lalo.

ʻO nā neurons nā pūnaeweleʻelele i loko o ka pūnaewele makaʻuʻole. ʻO kā lākou hana,ʻo ia ka hoʻounaʻana i nā leka mai kekahiʻaoʻao o ke kino i kekahi. Aia lākou i ka 50% o nā pūnaewele ma ka lolo. ʻO kahi'ē aʻe e pili ana i ka 50% he mau pūnaewele lele. ʻO kēia mau pūnaewele non-neuronal e mālama ana i homeostasis, hana myelin, a hāʻawi i ke kākoʻo a me ka pale no nā neu i loko o ka pūnaewele pūpū waena a me ka pūnaewele puni honua. ʻO nā pūnaewele Glial ka mālamaʻana e like me ka hoʻomaʻemaʻeʻana i nā mea make a me ka hoʻoponoponoʻana i nā mea'ē aʻe.

Nānā nā neurons i ka mea a mākou e manaʻo ai he 'gray matter'. Ke waihoʻia ka axon, hiki ke lōʻihi a pōkole paha, ma kahi mea momona maʻemaʻe (myelin), hiki keʻae i nā hōʻailona e holo me ka wikiwiki. ʻO kēia keʻokeʻo keʻokeʻo a iʻole ka hoʻoponoponoʻana,ʻo ia ka mea i kapaʻia he 'mea keʻokeʻo'. ʻO nā Dendrite e loaʻa nei kaʻikeʻaʻole loaʻa iā lākou kaʻike. Hāpai ka'ōpiopio'ōpio i nāʻaoʻao lolo a me nā ala. Hiki nō ia i ka hoʻohuiʻana ma o ka hoʻokalaʻana.

Nā hōʻailona me nā kinipona

Hoʻokomoʻia kā mākou mau hua'ōlelo ma keʻano o nā leka uila i kapaʻiaʻo nā pulupuna nerve a iʻole nā ​​hana kūpono. No ka hoʻolālāʻana i keʻano o ke kīpē, pono mākou e hauʻoli nui, no ka manaʻo a iʻole kaʻike, e hoʻokuʻu i kahi nalu i ka lōʻihi o ke kele e hoʻoulu aiʻole e pale i nā neurotransmit ma ka hope o ke axon. Nā mea likeʻole me nā kukui, nā kiʻi, ke kani a me ke kaomi e hoʻonāukiuki i nā neuronuʻike. [/ X_text] [/ x_column] [/ x_row]

Hiki i nāʻike ke holo mai kekahi neuron a hiki i kekahi neuron ma kahi o ka hanana aʻawa paha. ʻAʻole i kū pono nā neuron i kekahi,ʻo hanana He wahi liʻiliʻiʻuʻuku ia e hoʻokaʻawale ana i nā leu. ʻO nā neurons kēlā me kēia wahi ma waena o nā kūkākūkā 1,000 a me 10,000 a iʻole nā ​​'synapses' me nā mea likeʻole. Hoʻokumuʻia kahi hoʻomanaʻo me ka huiʻana o nā neurons e honi ana i kaʻala,ʻike, nā kani a me nā paʻi paʻi pū.

Ke neʻe a neʻe paha kahi aʻa a hana paha a hiki i ka hopena o ke axon ma kāna pahu, hoʻonāukiuki ia i nā ʻano kaʻina ʻē aʻe. Ma ke kikowaena aia kekahi mau vesicle liʻiliʻi (ʻeke) i hoʻopihapiha ʻia me nā neurochemicals like ʻole e hana i nā ʻano pane like ʻole. Hoʻonohonoho nā hōʻailona ʻokoʻa i nā vesicle i loaʻa i nā neurotransmitters like ʻole. Neʻe kēia mau vesicle i ka lihi loa o ka terminal a hoʻokuʻu i kā lākou ʻike i ka synaps. Ke neʻe nei ia mai kēia neuron ma waena o ka huina a synaps paha a pīhoihoi a kāohi paha i ka neona hou.

Inā he emiʻana o aiʻole ka nui o nā neurochemical (e laʻa me ka dopamine) a i ʻole ka helu o nā mea loaʻa, ʻoi aku ka paʻakikī o ka leka e hoʻohele. Loaʻa nā kānaka me ka maʻi maʻi Parkinson i ka hōʻailona hōʻailona maikaʻi. Unuhi nā pae kiʻekiʻe o nā neurochhemical a i ʻole nā ​​mea loaʻa i nā leka uila a i ʻole ala hoʻomanaʻo. Ke hele ka mea hoʻohana porn i kahi mea hoʻonāukiuki loa i ka manaʻo, lilo i mau ala i ikaika a ikaika hoʻi. Holo maʻalahi ka uila i lalo iā lākou me ka maʻalahi. Ke haʻalele ke kanaka i kahi ʻano maʻamau, pono ia i kahi hana e hōʻalo i kēlā ala o ke kūpaʻa liʻiliʻi a me ke kahe maʻalahi.

Neuromodulation no ka ke kaulike ka papa hana i hāʻawiʻia neuron hoʻohana ia i hoʻokahi aʻoi aku paha nā kinona e hoʻoponopono i nā heluna lehulehu o nā neurones. Heʻokoʻa kēia i ka wā kahiko ke kaʻina synaptic, kahi e hoʻopiʻi pono ai kekahi neuron presynaptic i kekahi hoa postsynaptic, kahi e hoʻokuʻu i kaʻike. ʻO nā neuromodulators i hūnāʻia e kahi hui liʻiliʻi o nā neurons e hele ma waena o nā pūʻali nui o ka pūnaewele'ōpiopio, e hoʻopili ana i nā neu. ʻO ka mea nui neuromodulators i loko o ka pūʻulu waena dopamineserotoninacetylcholinehistamine, a norepinephrine / noradrenaline.

Hiki ke noʻonoʻoʻia ka neuromodulation ma keʻano he neurotransmitter ka mea i hoʻopiliʻoleʻia e ka nehu pre-synaptic iʻole i uhakiʻia i lalo i kahi ka melika. ʻO nāʻano neuromodulators ke hoʻopau i ka manawa nui o ka ka wai o ka maʻi (CSF), influencing (a i ʻole "modulate") i ka hana o kekahi mau neurons ʻē aʻe i ka ka lolo. No kēia kumu, ua manaʻoʻia kekahi mau neurotransmitters e neuromodulators, e like me ke serotonin a me ka acetylcholine. (e nānā i wikipedia)
