This is a high-power picture of the interthalamic adhesion of an 81-year-old man with a clinical diagnosis of Dementia with Lewy Bodies. Again, see the collection of neuron cell bodies along with glial cells. I should remind you that not everyone has an interthalamic adhesion (about 20% are lacking this grey matter), and women are more likely to have this structure than do men. Nobody knows why this is, or what the function of the structure is. I supporse there are two possibilites, either it is of no practical importance, or there is an alternative way in which those lacking an interthalamic adhesion can process the information otherwise reserved for this structure.
