nervous system
|
• 30 mg/kg kainic acid induces stronger seizures than in wild-type mice
|
|
• misrouted thalamocortical axons (TCAs) are observed in mutants but not in controls, similar to the complete Cnr1tm1.1Ltz total null animals at E16.5
|
|
• deficits in fasciculation at E16.5 are similar to those observed in Cnr1tm1.1Ltz total null animals at E16.5
|
behavior/neurological
|
• 30 mg/kg kainic acid induces stronger seizures than in wild-type mice
|
|
• mutants eat less than controls on the first day of a novel palatable food test, however they progressively increase their palatable food consumption over the next 4 days to a similar level as in controls
• mutants display a very limited physical interaction with a novel object, when the palatability component is removed
|
|
• mutants take more time to approach and eat novel food on the first exposure compared to wild-type mice, indicating increased behavioral inhibition in the approach of novel palatable food
• mutants exhibit an increase in both the latencies of contact with the novel food item and to displace the novel object

mortality/aging
|
• following injections of kainic acid (an excitotoxin) mutant mice carrying the transgene display decreased survival compared to mutant mice not carrying the transgene
|
behavior/neurological
|
• following injections of kainic acid (an excitotoxin) mutant mice carrying the transgene display more severe seizures compared to mutant mice not carrying the transgene
• seizure severity did not differ between mutant mice carrying the transgene and null mice homozygous for Cnr1tm1.1Ltz

• seizure severity did not differ between mutant mice carrying the transgene and null mice homozygous for Cnr1tm1.1Ltz
|
|
• kainic acid treated mutant mice carrying the transgene have significantly more apoptosis in the CA1 and CA3 regions of the hippocampus compared to mutant mice not carrying the transgene

• however, diazepam protects mice and wild-type mice similarly against kainic acid-induced seizures
|
|
• mutants exhibit a hyperphagic phenotype compared to controls on the first day of a novel palatable food test, and maintain the higher food intake over the course of the experiment
• mutants show high levels of physical interaction with a novel object from the first experimental day even when the palatability component is removed
|
|
• mutants do not show any safety behavior towards the novel food and immediately consume the maximal amount, indicating impaired regulation of behavioral inhibition
• mutants exhibit shorter latencies to contact with the novel food item and to displace the novel object
