No residual effects were found in learning of an eight-arm radial maze task, nor on a differential reinforcement of low-rate responding (DRL) task, nor on open field activity.

On the other hand, two-way shuttle box avoidance learning was facilitated by previous cannabis treatment, since cannabis-treated rats exhibited shorter mean latencies to avoid footshock than vehicle by: Residual effects of chronic cannabis treatment on behavior in mature rats.

Stiglick A, Kalant H. Mature rats (starting weight at least g) were treated daily with cannabis extract (daily THC dose 20 mg/kg) for 3 months. After a 1- to 4-month drug-free period, residual effects Cited by: Chronic oral administration of cannabis extract to rats (daily Δ 9 dose 20 mg/kg) was examined for its residual effect on open field activity and DRL (differential reinforcement of low-rate responding) performance, following a 2–3-month drug-free period.

Locomotor activity during the latter part of an open field test was markedly increased in rats previously treated for either 6 months or 3 months with Cited by: The inhibition was age related, with the most marked effect being in the infant (3-day-old) rat.

Acute administration of THC and other cannabinoids brought about morphological changes, viz. a reduction in the number of nuclear membrane-attached ribosomes (NMAR) in infant rat brain.

The reduction of NMAR was dose and time related, and reversible. Several laboratories have reported that chronic exposure to deltatetrahydrocannabinol (THC) or marijuana extracts persistently altered the structure and function of the rat hippocampus, a paleocortical brain region involved with learning and memory processes in both rats and by: PDF | Synthetic cannabinoids (SCs) have rapidly proliferated as recreational drugs, and may present a substantial health risk to vulnerable populations.
