Cholinergic synapses and the organization of contrast detection in the crayfish optic lobe.
The actions of acetylcholine (ACh) were examined on 4 classes of multicolumnar interneurons whose dendrites lie in close proximity to the putative cholinergic transmedullary neurons described in the companion report. ACh-elicited responses in each cell type resemble visually elicited synaptic events and persist following synaptic blockade with 20 mM CoCl2. Tangential cells exhibit a hyperpolari...
متن کاملMapping membrane potential transients in crayfish (Procambarus clarkii) optic lobe neuropils with voltage-sensitive dyes.
Voltage-sensitive dyes NK 2761 and RH 155 were employed (in conjunction with a 12 x 12 photodiode array) to study membrane potential transients in optic lobe neuropils in the eye stalk of the crayfish Procambarus clarkii. By this means we investigated a pathway linking deutocerebral projection neurons, via hemiellipsoid body local interneurons, to an unidentified target (most likely neurons pro...
متن کاملImmunocytochemical Localization of Amines and GABA in the Optic Lobe of the Butterfly, Papilio xuthus
Butterflies have sophisticated color vision. While the spectral organization of the compound eye has been well characterized in the Japanese yellow swallowtail butterfly, Papilio xuthus, neural mechanisms underlying its color vision are largely unexplored. Towards a better understanding of signal processing in the visual system of P. xuthus, we used immunocytochemical techniques to analyze the ...

abstract هنجارهای بومی سازی در ترجمه متون چندوجهی فارسی:مورد دموهای بازیهای کامپیوتری چکیده اهداف عمده مطالعه حاضر به سه دسته تقسیم میشوند: 1) بررسی مشکلات احتمالی ترجمه دموهای (فیلمهای) بازیهای کامپیوتری،2) تعیین هنجارهای بومی سازی در ترجمه دموهای (فیلمهای) بازیهای کامپیوتری و 3) تعیین ایدئولوژیهایی که این هنجارها در جامعه نشان میدهند. به این منظور، ابتدا، مجموعه ای ازدموهای (فیلمهای) ب...
15 صفحه اولAcetylcholine release and choline uptake by cuttlefish (Sepia officinalis) optic lobe synaptosomes.
Acetylcholine (ACh), which is synthesized from choline (Ch), is believed to hold a central place in signaling mechanisms within the central nervous system (CNS) of cuttlefish (Sepia officinalis) and other coleoid cephalopods. Although the main elements required for cholinergic function have been identified in cephalopods, the transmembrane translocation events promoting the release of ACh and t...
