How will Brain Science be used in the future?

We can use brain science to perform neurosurgeries on patients by finding out which brain structure is which. For example, the amygdala is associated with mood/anger so an extremely angry person can have their amygdala removed (idk if this is even possible.) The hippocampus is used for memory, Broca's area for forming speech, Wernicke's area for understanding speech. Angular gyrus for converting images into audio, like if we see a trumpet we'd associate it with music. Also, association areas make us smarter than most animals. Neurons can be computed into a microchip to fly an autopilot airplane. Drug patients can be understood why they act drunk/depressed/hyper because some alcohol/meth can mimic dopamine and seratonin pathways. Also, split brain patients can use their left hand to draw what they see on the right. The left brain's plasticity will fill in the functions of what the right brain would do.

WATCHING DEATH!

Scientists think death is the end of personal consciousness. Religious people think that their spirits and souls live on. Near-death-experience people claim that they "travel down a long tunnel of light, looking down their body." These are caused by disorganized brain signals while on the verge of dying. The most important experiment that’s never been done is to take fMRI or PET scans of people as they die.
