Simple Method for Evaluation of Planum Temporale Pyramidal Neurons Shrinkage in Postmortem Tissue of Alzheimer Disease Patients

Figure 1

Example of the PT sample from ctrl and AD group (above view, left and right control and AD). Four symbols indicate four positions within the PT where brain tissue was collected and where pyramidal neurons in the cortical layer 3 were measured (STG, HG, I, and SR). Ctrl = control group, AD = Alzheimer disease group, L = left, and R = right. Equations in the lower half of the picture show asymmetries within ctrl, AD, and between ctrl and AD.
