alleged uses: there are reducing learning time and sleeping needs (theta waves are thought to improve learning, since children, who have stronger theta waves, and remain in this state for a longer period of time than adults, usually learn faster than adults; and some people find that half an hour in the theta state can reduce sleeping needs up to four hours; however, this is supposed to happen with any way to get into theta state, e.g. meditation); some use them for lucid dreaming and even for achieving out-of-body experiences, astral projection, telepathy and psychokinesis. However, most people believe that these phenomena (except lucid dreams, which are acknowledged even by mainstream science) do not exist, let alone that they can be achieved by entraining the brain to a specific frequency.
Binaural beats have also been used experimentally for the treatment of addictions, and for the recovery of repressed memories, but as with other techniques this can lead to false memories.

I'm taking 300mg Wellbutrin and 50mg Zoloft. I'm curious what effects (short term and long term) they have on my brain. I don't think I've noticed anything different except an extreme drop in sex drive. I also seem to be gaining weight easily. What would happen if I just stopped taking them?

I've played Gabriel Knight - The Beast Within and in there some wolf researcher talks about something called the language of death. The thing is, predators don't choose their pray on the basis of their health etc. Sometimes they catch a diseased animal but let it go and sometimes a seemingly healthy animal strays from the others to let itself caught. The predator and prey comminucate in a sort of language of death, the prey telling them if they want to go or not. The domesticated animals don't learn this language and so the wolves start killing and they don't stop. It seems a bit far fetched but is there any truth in this?

Hi,

How could a 5-volt logic circuit control a 12-volt motor? Which parts of the circuit are 5-volt and which are 12-volt?

Here's the diagram of the circuit: http://i137.photobucket.com/albums/q208/infinitbelt/circuit.jpg


Any ideas?


Thanks!

What is THE WARMEST clothing for EXTREMELY
cold and windy weather?

Fur (what sort)? Leather? Synthetics (what sort)?

IMPORTANT:
I ride a motorcycle
even when it's well under 30°C.
At 60 mhp the wind chill can make it as if it were
as low as -10°C with the wind cutting you to the core.
And when your just siting on the bike you don't generate
much body heat (little movement).

I think I may need
mittens (made of ?), boots (made of ?),
underwear/base layer (made of ?), insulating layer/s
(made of ?), and a outer or shell layer/coat (made of ?)
made for a place like ANTARCTICA in bad weather
(-89.4°C/-129°F with hi winds).

I nearly don't care what it looks like.
I just don't want to be cold.
