The depression induced in the monocular region would represent all objects outside of the central visual field, while the potentiation induced in the binocular region would represent objects in the central visual field. Regions of the brain that are involved in reward processing are less active in depressed people.

Collapse-related: Sinkhole: a depression formed as a result of the collapse of rocks lying above a hollow. The latest research shows that the size of specific brain regions can decrease in people who experience depression.
This chart shows how each region of the world is affected by depression; the orange line indicates the number of years spent living with clinical depression per every 100,000 people. Areas that play a significant role in depression are the amygdala, the thalamus, and the hippocampus (see Figure 1).

By contrast, it reduced activity in parts of the lateral prefrontal cortex - a region important in regulating emotional responses and shown to be underactive in depression.
Single brain region links depression and anxiety, heart disease, and treatment sensitivity. There are many other brain regions, and pathways between specific regions, thought to be involved with depression, and likely, no single brain structure or pathway fully accounts for clinical.

It formed as Earth pulled apart at the seams of plate boundaries. One meta analysis on first episode depression observed distinct patterns of grey matter reductions in medication free, and combined populations; medication free depression was associated with reductions in the right dorsolateral prefrontal cortex, right amygdala, and right inferior temporal gyrus; analysis on a combination of medication free and medicated depression found reductions in the left insula, right supplementary motor area, and right middle temporal gyrus. This chart shows how each region of the world is affected by depression; the orange line indicates the number of years spent living with clinical depression per every 100,000 people.
