Wistar rats (n = 58) were injected subcutaneously during the lactation period with fluoxetine (5, 10, 20 or 40 mg/kg/day) and cortical spreading depression (SD) was recorded immediately after weaning (25-30 days of life). An additional group (10 mg/kg; n = 8) was SD-recorded at 60-70 days. As compared to the saline-injected (n = 24) or "ingenuous" (n = 16)(More)
Marijuana is a widely abused illicit drug known to cause significant cognitive impairments. Marijuana has been hypothesized to target neurons in the hippocampus because of the abundance of cannabinoid receptors present in this structure. While there is no clear evidence of neuropathology in vivo, suppression of brain mitogenesis, and ultimately(More)
Cortical spreading depression (CSD) propagation was investigated in rats under dietary essential fatty acid (EFA) deficiency over two generations (F1 and F2). Wistar rat dams received diets containing 5% fat either from coconut-oil (EFA-deficient) or soybean-oil (control). F1-pups received their dams' diets until the day of CSD recording (30-40 days or(More)
OBJECTIVE We investigated the effect of early-in-life administration of L-arginine, combined with physical exercise, on cortical spreading depression (CSD) in young and adult rats. METHODS L-arginine (300 mg/kg/day, n = 40) or distilled water (vehicle, n = 40) was given to the rats during postnatal days 7-35 by gavage. Physical exercise (treadmill) was(More)
Natural cell death is a degenerative phenomenon occurring during the development of the nervous system. Approximately half the neurons initially generated during this period die. The role of trophic molecules produced by target and afferent neurons as well as by glial cells controlling this regressive event has been extensively demonstrated. The aim of this(More)
