Does the brain pick up messages from the outside world?

Indirectly, yes. The skin passes feelings of soft, hard, cold, or hot to the brain. The eyes send images. The nose sends smells, and the mouth sends flavors. The ears send sounds and balance. These are all processed in the brain.


Can heartbeat restart spontaneously after death?

Death occurs when the person is without the functions of their brain (Some brain cells live on,meaning the brain didnt "die"). Prior to that, the person is not dead, regardless of what the heart is doing. If they are not dead, the heart is not restarting after death, but may continue to beat if the nerves send their last messages after death to the heart. It can happen. But its extremely unlikely.

How can the brain tell if something is hot?

The skin, including the skin on your hands, has thermoreceptors that send messages to the brain about temperature. However, they respond to CHANGES in temperature, not temperature itself. So, if you come in from the cold, all surface temperatures will feel very warm, but gradually as you warm up, the surfaces will seem neutral. And, think about what happens when you put your hand in a lake on a hot day - it feels really cold, but if you jump in, eventually your skin will adjust to the temperature. Now, if the surface is burning hot or freezing cold, the pain receptors, not the thermoreceptors, in your skin react.
