(I always wonder if superlative reviews are plants by the app developers. This isnt. Trust me.)
The visuals are clear, detailed, and move smoothly. The content has a wide breadth, and the depth of information is rich and diverse. I can simply explore the anatomy of the brain, moving from layer to layer, front to back, side to side, system (vascular) to system (nervous), etc. Or I can learn about a syndrome by starting with the glossary and moving from there. Or if I want to know more about one part of the brain I can click on a pin label and proceed from there, finding out about its physiology and/or clinical relevance.
A friend who is a speech therapist uses this app to explain syndromes to clients and to teach interns. I find it helpful as a psychologist in furthering my understanding of neurological matters, and I just enjoy exploring this miraculous organ in our skulls.
I wish the glossary included basic terms such as sagittal and sulci, but its a minor criticism.
Pocket Brain is an exemplar of the capacity of tablet technology. And it costs far less than any traditional book on the same topic.
