The ampulla of Lorenzini of juvenile Carcharhlinus leucas differ histologically from those previously described for other elasmobranchs. The wall of the ampullary canal consists of protruding hillock-shaped epidermal cells that appear to se...

The electric sense of elasmobranch fishes (sharks and rays) is an important sensory modality known to mediate the detection of bioelectric stimuli. Although the best known function for the use of the elasmobranch electric sense is prey dete...
The electric sense of the paddlefish: a passive system for the detection and capture of zooplankton prey [0.03%]

Behavioral and electrophysiological experiments have shown that the elongated paddlefish rostrum, with its extensive population of ampullae of Lorenzini, constitutes a passive electrosensory antenna of great sensitivity and spatial resoluti...

Life evolved from the primeval world of physics. Sensory systems inform animals of the natural environment, enabling them to conduct responsively. The discovery of weak, DC bioelectric fields in the vicinity of aquatic organisms and the rol...
Information-processing demands in electrosensory and mechanosensory lateral line systems [0.03%]

The electrosensory and mechanosensory lateral line systems of fish exhibit many common features in their structural and functional organization, both at the sensory periphery as well as in central processing pathways. These two sensory syst...
Characterization of a mouse tet-on glia precursor cell line in vitro and in vivo using the electrophysiological measurement [0.03%]
利用电生理记录技术在体外和体内表征小鼠tet-on胶质前体细胞系的特征

We report here a partial characterization of a "tet-on" glia O2A precursor cell line established from the reverse tetracycline-transactivator (rtTA)-SV40 T antigen (Tag) double transgenic mice. In culture, withdrawal of doxycycline prevents...
Modulation of neuronal survival and excitability by an astroglia-derived factor [0.03%]
星形胶质细胞衍生因子对神经元生存和兴奋性的影响

We summarize here currently available data related to an astroglia-secreted factor that induces neuronal apoptosis and behaves as an inhibitor of ionotropic inhibitory GABA(A) and glycine receptors. ...
Importance of astrocytic inactivation of synaptically released glutamate for cell survival in the central nervous system--are astrocytes vulnerable to low intracellular glutamate concentrations? [0.03%]
星形胶质细胞灭活突触释放的谷氨酸对中枢神经系统细胞存活的重要性-星形胶质细胞是否容易受到胞内低浓度谷氨酸的影响？

Laurence Had-Aissouni et al.
Multiple levels of neuron-astrocyte interactions do exist at glutamatergic synapses, glial glutamate transporters being involved in most of them. Inactivation of synaptically released glutamate is not only important for the phasic aspect of...
The presence of astrocytes enhances beta amyloid-induced neurotoxicity in hippocampal cell cultures [0.03%]

A characteristic feature of neuritic plaques in Alzheimer's disease is represented by the presence of activated astrocytes, surrounding dystrophic neurons and beta-amyloid deposition. To explore the role of astrocytes in in vitro beta-amylo...

In rat brain, calcification associated with excitotoxicity has been proposed to play a protective role, whereas in human brain, nonartherosclerotic calcification is present in several pathological conditions without any clear significance. ...
