Neuroplasticity

Kalmar neuroplasticity ta rushe kamar yadda neuro don "neuron", kwayoyin jikinsu a cikin kwakwalwar mu da kuma tsarin jin dadi. Plastics shi ne "mai sauya, mai sauƙi, mai sauƙi." Neuroplasticity yana nufin ƙwaƙwalwar ƙwaƙwalwa don canzawa a amsa ga kwarewa. Kwaƙwalwar tana yin haka ta hanyar ƙarfafa haɗi tsakanin wasu kwayoyin jijiya yayin da ya raunana haɗin tsakanin wasu.

Neurons

Ƙwaƙwalwarmu tana cikin ɓangaren ƙaƙƙarfan ƙwayar cuta. Ya ƙunshi tsarin kulawa na tsakiya (CNS) da tsarin jin dadin jiki (PNS). CNS tana ƙunshe da kwakwalwa da kuma kashin baya.

2. Neurons sadarwa tare da juna ta hanyar hanyar electrochemical.
3. Neurons suna ƙunshe da wasu sassa na musamman (alal misali, synapses) da sunadaran (alal misali, neurotransmitters). Dubi kasa.

Neburons ne manzo ne a cikin sashin jiki. Ayyukansu shine don aika saƙonni daga wani ɓangare na jiki zuwa wani. Sun kasance game da 50% na sel a kwakwalwa. Sauran kamar 50% sune Kwayoyin iska.

Neuromodulation ne physiological tsari da abin da aka ba neuron yana amfani da sunadarai daya ko fiye don tsara yawancin ƙananan igiyoyi.
