Final answer:
Scientists can manipulate the brain through deep brain stimulation, non-invasive brain stimulation, and biofeedback or neurofeedback.
Step-by-step explanation:
Scientists can manipulate the brain in several ways:
- Deep brain stimulation (DBS): This surgical procedure involves the insertion of small electrodes in specific brain regions to improve memory functions.
- Non-invasive brain stimulation: Transcranial stimulation, using electric or magnetic stimulation, can enhance sensorimotor skills, memory, attention, and problem-solving.
- Biofeedback or neurofeedback: This technique combines EEG readings of brain activity with operant conditioning to train individuals to produce desired brain states.
