Seen at the ultrastructural level, dendrites contain al- most all of the organelles that can be found in the cell body cytoplasm. In particular, the presence of free and membrane-bound ribosomes suggests that dendrites are the site of intense protein synthesis. This idea is corrobo- rated by...
We report that immature neurons do not contain these scarcely understood organelles, since they can be seen for the first time in very few, mature neurons of the 30 day rat; their number constantly increases during the following 4 months. These cytoplasmic inclusions can be equally seen in the...
Modern light microscopy, including super-resolution techniques, has brought about a demand for small labeling tags that bring the fluorophore closer to the target. This challenge can be addressed by labeling unnatural amino acids (UAAs) with bioorthogonal click chemistry. The minimal size of the UAA...
13,14. However, these methods aim to discover connections among the recorded neurons, whereas the majority of synaptic inputs come from unobserved neurons. Therefore, it remains a challenge to reveal the hidden neuronal circuitries by using the activity statistics of a limited number of neurons...
In decerebrate, paralyzed and artificially ventilated cats, we recorded the discharge of 64 motor axons supplying the pharyngeal muscles. Filaments contain... L Grélot,JC Barillot,AL Bianchi - 《Experimental Brain Research》 被引量: 186发表: 1989年 Changes in afferent and efferent phrenic activitie...
“开学 了，可我一点兴奋劲儿都没有，因为原本细嫩的脸上长了很多红色的小痘痘。我怎么见人呢……”肖燕对好朋友王娜说。王娜应该这样劝说肖燕（）①青春期的生理变化是正常的 ②外在形象无关紧要，只要成绩好就行③要追求内在美与外在美的统一 ④要正视自己身体的变化，这是我们对自己的尊重 ...
Awl/auchene hairs are shorter than guard hairs, contain three or four rows of medulla cells, and together constitute ∼23% of trunk hair follicles (Figure S1B, middle). The third type, zigzags are the finest, most abundant type of hair follicle, comprising ∼76% of trunk hairs. ...
Method for producing a population of mammalian neurons and/or smooth muscle cells comprising contacting at least one mammalian neural stem cell with a culture medium containing one or more growth factors from the TGF-β super family and detecting the differentiation of stem cell to a population of...
This is similar to results from larval mdIV neurons that are responsive to multiple forms of noxious stimuli including thermal, mechanical and ROS. However, some afferents of the Splanchnic C fibers were only responsive to H2O2. Based on the observation that these fibers contain neuropeptides known...
The responses of adult parasympathetic ganglion neurons to injury and the neurotrophic mechanisms underlying their axonal regeneration are poorly understood. This is especially relevant to penis-projecting parasympathetic neurons, which are vulnerable to
