The Connection Between Positive and Negative in the Brain

People with depression cannot experience joy or pleasure, even in things that are normally joyful to them. We allis just like we know when we have cold, we no longer smell or taste food as well. How does that happen? And what we've found is that there are specific connections that do indeed have the ability to add or subtract value,. positive or negative value and layer those on to even things that are completely neutral, that have no value at all. This can happen instantaneously. So this has been a very important insight, that this value is just a physical and electrical, well defined process like anything else in biology. The hope is to communicate that to people.
