Neuropathology of depression
Professor Helen Mayberg describes a network of structures linked to depression - the cingulate, hypothalamus, brainstem, and amygdala. These are influenced by frontal and parietal cortices.
Well it turns out, unlike what we thought 30 years ago, where the focus was on the frontal lobe, that this [neuropathology of depression] is really the crosstalk between very ancient limbic or emotional centers of the brain that control drives such as the cingulate, the hypothalamus, the brainstem and the amygdala. [These structures work] in combination and their communication with thinking areas of the brain, predominately the frontal and parietal cortex. So it turns out that with imaging, weâ€™re able to evaluate the brain in action and literally identify nodes in different parts of the brain that arenâ€™t functioning properly. But it isnâ€™t just any one region, itâ€™s the combination of regions. Itâ€™s really the crosstalk between the limbic and the emotional areas almost being overactive in combination with thinking areas of the brain being underactive.

Professor Helen Mayberg discusses how deep brain stimulation (DBS) is applied to the subcallosal cingulate, a structure deep in the brain's white matter.
The G2C Brain consists of 30 interactive 3-D structures with information on associated functions, disorders, related brain damage, case studies, and links to contemporary research.
Professor Philip Shaw discusses three brain areas in relation to the neuropathology of ADHD: the frontal cortex, amygdala, and hippocampus.
The frontal lobe is part of the cerebral cortex and is the largest of the brain's structures. It is the main site of so–called 'higher' cognitive functions.
Professor Judith Rapoport discusses correlates of attention in the frontal and parietal lobes, which are related to the neuropathology of attention.
The occipital cortex is the primary visual area of the brain. It has different groups of neurons that separately encode color, orientation, and motion information.
Autism is not associated with any single deficit in the brain.
Einstein's brain, was it different to yours?
The amygdala is a complex structure adjacent to the hippocampus. The amygdala is involved in processing emotions, and fear–learning.
