There is an excellent BBC Radio 4 programme called All in the Mind - Exploring
the limits
and potential of the mind. If you do not live in the UK, you may listen to the
latest edition
via the Internet. Just click on the following link (or copy and paste it into

The programme is very informative. For example, although today's programme was
about
LSD and Ecstasy (MAMD), it went into some detail about how the
neuro-transmitters
serotonin and dopamine function in the brain.
