Altered functioning of the glutamate system during critical periods of development is believed to play a role in various neurodevelopmental disorders, such as schizophrenia. Prepulse inhibition (PPI) of the acoustic startle response is deficient in people with schizophrenia. This study investigated ...

The present study examined the effects of neonatal exposure to serial low dose injections of the glutamate agonist, domoic acid (DOM), on learning and memory in two spatial memory tasks in the rat. Neonatal Sprague Dawley rats were given single daily injections of low dose DOM (20 microg/kg) over po...

Developing new therapeutants for stroke requires animal models in which typical stroke outcomes can be detected. In rats, temporary occlusion of the middle cerebral artery (MCAo) closely resembles reversible human ischemic stroke, but most neuroprotection studies have used limited, short-term (1-2 w...

Historically, all commercially available kainic acid has been derived from a single biological source using a consistent method of extraction and purification. That source became unavailable in 1995. Recently, three new commercial suppliers of kainic acid have made the product available, but the sou...

It is well established that the developing brain is a highly dynamic environment that is susceptible to toxicity produced by a number of pharmacological, chemical and environmental insults. We report herein on permanent behavioural and morphological changes produced by exposing newborn rats to very ...

Prepulse inhibition (PPI) of the acoustic startle response is a measure of sensory motor gating, and is affected in various neuropsychiatric disorders. Although PPI has been used extensively to study both the neural effects of such conditions, as well as in the search for animal models, a number of ...

Activity in the mesocorticolimbic dopamine system is linked to responses to novelty, reward, and drug-seeking behaviours. Glutamate signaling, through kainate receptors, has been shown to modulate dopamine release in this pathway. In the present study, a low, overtly non-convulsive dose of the kaina...
