Putative neurotransmitters of the avian visual pathway.
The ability of homogenates of the chick optic lobe to accumulate a series of possible neurotransmitters has been studied. High affinity uptake of several possible neurotransmitters was examined in optic lobes of 21-day-old embryos that had a single eye removed on the third day of incubation and in 23-day-old chicks that had an eye removed at hatch. Embryonic enucleation resulted in severe reduc...
متن کاملCalcium-dependent release of putative neurotransmitters in the chick visual system.
The calcium-dependent release of putative neurotransmitters has been studied in the chick brain. Several radioactive compounds were taken up into chick optic lobe homogenates by a highaffinity sodium-dependent transport mechanism. At a· concentration of potassium sufficient to cause extensive depolarization, a large proportion of the efflux of the accumulated labeled compounds was calcium depen...
متن کاملRegional distribution of some enzymes involved with putative neurotransmitters in the human visual system.
SUMMARY Levels of protein and activity of several enzymes were determined in different portions of the visual system of the human brain. The enzymes studied were total cholinesterase (TChE), acetylcholinesterase (ACHE), pseudocholinesterase (ChE), choline acetyltransferase (ChAc), monoamine oxidase (MAO), and N-methyltrans-ferase (NMT). Brains of 17 patients were obtained at autopsy. The specim...
متن کاملthe effect of using visual aids on the development of speech act of disagreement among iranian intermediate efl learners
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
Putative neurotransmitters in the rat cochlea at several ages.
We have performed a longitudinal study of the content of the putative neurotransmitter substances, enkephalin, dynorphin, and acetylcholine (ACh), in the cochlea of the Fischer 344 rat. It is the first study of transmitters in the rat cochlea over an extended time span. This study also provides biochemical verification of the presence of ACh in cochlear tissues. No change was seen in the cochle...
