[Blunderov] But only in high doses; although hardcore devotees of cognitive
enhancement probably will not consider this to be a significant
inconvenience.
The 60's/70's generation is now in power. What happened? Legalize it,
dammit!

Cannabis boosts brain power in rats Medical Research News Published: Sunday,
16-Oct-2005
Scientists now say that Cannabis, the third most popular recreational drug
after alcohol and tobacco, could boost brain power. Canadian researchers
found that experiments on rats which were given a potent cannabinoid, showed
the drug stimulates the growth of new brain cells.
It appears that the drug caused neurons to regenerate in the hippocampus, an
area that controls mood and emotions, after one month of treatment.
Apparently its effect was similar to that of the antidepressant drug Prozac,
which also stimulates nerve growth in the hippocampus. The rats were less
anxious and more willing to eat in a novel environment that would normally
make them fearful.
The new research suggests that the size of the dose may be crucial. The
results showed that regular injections of high, but not low, doses of the
artificial cannabinoid HU210 were associated with anti-anxiety and
antidepressive effects.
The researchers from the University of Saskatchewan, Canada, say that most
drugs, including alcohol, heroin, cocaine and nicotine, have been shown to
destroy nerve cells in the hippocampus. This study suggests that
cannabinoids are the only illicit drug that can promote adult hippocampal
neurogenesis following chronic administration.
This new finding does of course contradict previous research highlighting
the risks of cannabis use, including a heightened degree of psychosis in
vulnerable users, and an increased risk of lung cancer similar to that in
tobacco smokers.
The authors agree that regular cannabis users are known to suffer acute
memory impairment, as well as dependency and withdrawal symptoms, but the
new research suggests that the size of the dose may be crucial.
The results showed that regular injections of high, but not low, doses of
the artificial cannabinoid HU210 were associated with anti-anxiety and
antidepressive effects.
The scientists say that these complicated effects of high and low doses of
acute and chronic exposure to cannabinoids may explain the seemingly
conflicting results observed in clinical studies regarding the effects of
cannabinoid on anxiety and depression.
The study emerged from the recent discovery that, unlike other parts of the
brain, the hippocampus can generate neurons throughout the lifespan of
mammals, including humans.
The team says that natural selection has conserved cannabinoid receptors in
animals that have been separated by evolution for 500 million years,
suggesting they have an important biological role.
Cannabinoids appear to alter the effects of pain, nausea, tumours, sclerosis
and other disorders in both animals and humans.
In the experiment the rats were given regular injections of HU210 for a
month. At the end of this time, hungry animals showed significantly less
reluctance to eat in a novel environment. Rats are normally neophobic - wary
of new situations.
The study is published in the Journal of Clinical Investigation.

I have reservation about what this experiment really means. Brain cell
growth does not necessarily mean "brain power"; any alteration of
behavior also corresponds to some brain cell growth. Everything must be
somehow encoded in brain cells.
In this case, what they found was that the mice loosened up, with a
corresponding brain cell growth.

I clicked "send" too fast. I wanted to add that the "high doses" factor
probably means that high doses make the change of behavior more permanent.

[Blunderov] Admittedly the piece is really blatant propaganda but I felt
positively inclined towards it anyway. Cognoscenti will well know that the
chief pharmacological actions of THC are related to sleep and appetite.
Whether more of this is desirable or not would, I suppose, depend.
Cognoscenti might also well suspect that the rats simply had such an
incredible case of the munchies that it overcame all caution.
Best Regards.
