Document Summary
Patients were brain injuries/diseases can be observed with different behavior like talking too much or too little. Trans-cranial magnetic stimulation (tms) can create short-term lesions in the human brain. *a magnetic pulse is passed through the brain and alters brain composition by altering neurons in the brain when the magnetic pulse stops, the brain goes back to normal. Temporal parietal junction: part of the brain which lets us try to understand someone else"s perspective. Electric convulsion therapy (ect): still used today in large hospitals for treating severe depression. *why it works is not exactly clear but there are side effects like memory loss. *tms is sort of like targeted ect on a smaller scale can possible help with depression. Ion channels found in phytoplankton respond to light. Scientists have taken these ion channels and implanted them into mice brains, forming a mouse brain with parts that are reactant to light.
