Tripartite synapses: astrocytes process and control synaptic information.
The term 'tripartite synapse' refers to a concept in synaptic physiology based on the demonstration of the existence of bidirectional communication between astrocytes and neurons. Consistent with this concept, in addition to the classic 'bipartite' information flow between the pre- and postsynaptic neurons, astrocytes exchange information with the synaptic neuronal elements, responding to synap...
متن کاملPossibilistic Information Flow Control
Distributed systems make increasing use of encrypted channels to enable confidential communication. While non-interference provides suitable means to investigate the flow of information within distributed systems, it has proved to be rather difficult to capture the notion of encrypted channels in such a framework. In this paper, we extend the framework MAKS for possibilistic information flow in...

relations and friends. Conversely, insane conduct may be properly testified by a relation, but fail to be displayed when under observation in an institution. The medical evidence then will probably be that of mental deficiency. In such case the witness must balance the relative merits of hearsay statements and personal observation. Mental defect mnay be simulated by mental dullness resulting fr...
متن کاملExperience-dependent regulation of presynaptic NMDARs enhances neurotransmitter release at neocortical synapses.
Sensory experience can selectively alter excitatory synaptic strength at neocortical synapses. The rapid increase in synaptic strength induced by selective whisker stimulation (single-row experience/SRE, where all but one row of whiskers has been removed from the mouse face) is due, at least in part, to the trafficking of AMPA receptors (AMPARs) to the post-synaptic membrane, and is development...
متن کاملPresynaptic NMDARs in the Hippocampus Facilitate Transmitter Release at Theta Frequency
A rise in [Ca(2+)](i) provides the trigger for neurotransmitter release at neuronal boutons. We have used confocal microscopy and Ca(2+) sensitive dyes to directly measure the action potential-evoked [Ca(2+)](i) in the boutons of Schaffer collaterals. This reveals that the trial-by-trial amplitude of the evoked Ca(2+) transient is bimodally distributed. We demonstrate that "large" Ca(2+) transi...
