PediNeuroLogic Exam: Introduction: General Physical Examination
In the neurological assessment of the child don't neglect the general physical examination. Some of the parts of the general examination that are particularly important to note are the following: Somatic growth - measure height and weight and compare percentiles with head circumference; Search for dysmorphic features - carefully study the face especially the midface. There is the old adage that the face reflects the brain because anomalies of the midface are often associated with underlying brai

How Does a Motorcycle Engine Work?
This 3:30 minute video show how motorcycle engines work essentially as a big air pump. This video is about a four stroke engine works as explained by a certified motorcycle technician. The video moves too rapidly to be useful except as an overview. A handout with the names of the parts an a drawing of the engine may be of benefit.
PediNeuroLogic Exam: Newborn: Abnormal: Positions - Vertical Suspension
In vertical suspension there is the feeling that the baby is slipping through the examiner's hands because of the low tone in the shoulder girdle muscles. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.

Optogenetics: A light switch for neurons
This animation illustrates optogenetics -- a radical new technology for controlling brain activity with light. Ed Boyden, the co-inventor of this technology, is a professor at the MIT Media Lab and at the McGovern Institute for Brain Research, where he continues to develop new technologies for controlling brain activity.
