Hauv qhov no, dab tsi yog qhov inhibition ntawm lub retina?
Lateral inhibition yog qhov tshwm sim uas neuron cov lus teb rau qhov kev txhawb siab yog inhibited los ntawm kev zoo siab ntawm ib tus neeg nyob ze neuron. Lateral inhibition tau raug sim sim hauv retina thiab LGN ntawm cov kab mob [47].
Tsis tas li, uas yog qhov tseeb ntawm kev tiv thaiv ib sab? Lateral inhibition hais txog cov inhibition uas nyob sib ze neurons nyob rau hauv lub hlwb txoj kev muaj rau ib leeg. Qhov no txhais tau hais tias cov neeg nyob sib ze pom cov neurons teb tsawg dua yog tias lawv tau qhib rau tib lub sijhawm dua li yog tias ib leeg ua haujlwm ib leeg. Yog li qhov tsawg dua cov neurons nyob sib ze tau txhawb nqa, qhov ntau zog ntawm cov neuron teb.
Kuj tseem paub yog, yog qhov cuam tshuam sab nraud tseem ceeb rau kev txheeb xyuas cov npoo?
Lateral inhibition koom nrog kev txwv ntawm cov neurons los ntawm lwm cov neurons. Stimulated neurons inhibit kev ua ntawm cov neurons nyob ze, uas pab ua kom peb lub siab xav. Pom txwv tsis pub txhim kho ntug kev nkag siab thiab nce qhov sib txawv hauv cov duab pom.
Cov hlwb twg yog lub luag haujlwm rau kev tiv thaiv ib sab?
Lateral inhibition yog tsim nyob rau hauv lub retina los ntawm interneurons (kab rov tav thiab amacrine hlwb ) lub pas dej ua ke hla lub zej zog ntawm presynaptic pub rau tom ntej hlwb (photoreceptors thiab bipolar hlwb ) thiab xa inhibitory teeb liab rov qab rau lawv [14โ17] (Daim duab 2).
