Cortical and subcortical components of conditioned saccharin aversion in rats.
Taste aversion was elicited in rats offered 0.1 percent saccharin (conditioned stimulus) for 10 min and then poisoned 30 min later by lithium-chloride (unconditioned stimulus - 0.14 M, 2 ml/100 g i.p.). Similar reduction of saccharin intake on the next day was obtained in rats learning the task with intact brain or under unilateral cortical spreading depression (CSD) and tested with CSD in the ...
متن کاملMechanisms of spreading depression and hypoxic spreading depression-like depolarization.
Spreading depression (SD) and the related hypoxic SD-like depolarization (HSD) are characterized by rapid and nearly complete depolarization of a sizable population of brain cells with massive redistribution of ions between intracellular and extracellular compartments, that evolves as a regenerative, "all-or-none" type process, and propagates slowly as a wave in brain tissue. This article revie...
متن کاملPronounced hypoperfusion during spreading depression in mouse cortex.
We studied unique cerebral blood flow (CBF) responses to cortical spreading depression in mice using a novel two-dimensional CBF imaging technique, laser speckle flowmetry. Cortical spreading depression caused a triphasic CBF response in both rat and mouse cortex. In rats, mild initial hypoperfusion (approximately 75% of baseline) was followed by a transient hyperemia reaching approximately 220...
متن کاملGlutamate release through volume-activated channels during spreading depression.
Volume-sensitive organic anion channels (VSOACs) in astrocytes are activated by cell swelling and are permeable to organic anions, such as glutamate and taurine. We have examined the release of glutamate through VSOACs during the propagation of spreading depression (SD). SD was induced by bath application of ouabain in hippocampal brain slices and was monitored by imaging intrinsic optical sign...
متن کاملIon and transmitter movements during spreading cortical depression.
A reaction--diffusion system of equations whose components are the extracellular concentrations of K+, Ca++, Na+, Cl-, an excitatory neurotransmitter and an inhibitory neurotransmitter, is developed in order to model the movements of these substances through various kinds of membrane in brain structures. Expressions are derived from probabilistic arguments for the conductances induced in subsyn...
