Gait Exam: Normal Exam: Natural Gait
The patient should be able to walk with a smooth, coordinated gait. There should be normal associated movement of the upper extremities. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination permits "dissection" of the nervous system and localizes the disease when present. Instead of simply memorizing the components of the exam,
Motor Exam: Abnormal Examples: Lower Extremities - Inspection & Palpation
There is hypertrophy of this patient's left leg. Closer inspection of that extremity shows hyperpigmented skin lesions suggesting segmental neurofibromatosis. A thorough skin search can provide important clues to diagnosis especially in the neurocutaneous syndromes. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination permits "
Cranial Nerve Exam: Normal Exam: Cranial Nerve 5 - Motor
The motor division of CN 5 supplies the muscles of mastication (temporalis, masseters, and pterygoids). Palate the temporalis and masseter muscles as the patient bites down hard. Then have the patient open their month and resist the examiner's attempt to close the month. If there is weakness of the pterygoids the jaw will deviate towards the side of the weakness. The last test for this nerve is testing for a jaw jerk, which is a stretch reflex. Have the patient slightly open their month then pla
PediNeuroLogic Exam: Newborn: Abnormal: Primitive Reflexes - Stepping
With the baby held in vertical suspension and his feet touching the mat, he does not have the expected reciprocal flexion and extension of the legs. The stepping or walking reflex is absent in this baby. 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.
Water, Water Everywhere
Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and sur
Cranial Nerve Exam: Normal Exam: Smooth Pursuit
To test Smooth Pursuit ask the patient to keep watching the target without moving their head. Then move the target slowly from side to side and up and down. The eyes should be able to follow the target smoothly without lagging behind or jerking to catch up with the target. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination pe
PediNeuroLogic Exam: Newborn: Normal: Tone - Head Control
The strength and tone of the neck extensors can be tested by having the baby in sitting position and neck flexed so the baby's chin is on the chest. The baby should be able to bring the head to the upright position. The neck flexors can be tested by having the head in extension while in the sitting position. The baby should be able to bring the head to the upright position. These tests are an extension of the test for head lag and are done at the same time. A neuroscience tutorial focusing on th
Inheritance of Blood Groups
Fact-sheet with worked examples on the inheritance of blood groups (ABO only). Useful to show genetic crosses.
The Future of Learning
Although she is committed to boosting interactive digital technology for learning, Diana Rhoten’s talk is framed by movies. Waiting for Superman is the starting point: a good demonstration of how schools are failing our children, but very unimaginative, Rhoten says, when it comes to solutions. In fact, one of the ass
Where the Wired Things Are: A Day in the Life of a Modern Family
Vanessa Van Petten bears witness to a strange new future rapidly becoming reality: devices and apps available for every aspect of family life. Her Radical Parenting website draws on the perspectives and insights of teen interns and thousands of correspondents (including frustrated and befuddled parents), so Van Petten can knowle
Technology: Do Kids Need More or Less?
The ultimate questions for this Sandbox 2011 panel, posed by moderator Alan Gershenfeld, are “Where is technology not working? When is technology not the answer?” That’s a bold agenda for a panel of children’s media creators and a roomful of other producers in the industry, from Sesame Workshop, WGBH, 360 Kid, and elsewher
Plays Well With Others: Leadership in Online Collaboration
Amy Bruckman finds the accomplishments of such online collaborations as Wikipedia, Apache and Firefox “nothing less than astounding,” and is both eagerly seeking and hoping to foster the next creative group Internet sensation.
In her lab’s empirical studies, Bruckman has dissected different types of ensembl
