Strawberry Tongue

 

Tomisaku Kawasaki conducted much of his clinical work in Tokyo. 

 

 1961 – Kawasaki encountered a young child with an unusual constellation of symptoms: prolonged fever, rash, conjunctival injection, mucosal inflammation, and lymphadenopathy.

 

1967 – He published a landmark paper describing 50 children with what he termed

 

                           “Acute febrile mucocutaneous lymph node syndrome”

 Roger Sperry spent the most influential part of his career at California Institute of Technology (Caltech), where he conducted the groundbreaking research that later earned him the Nobel Prize.

 

 

 

 

 

 Split Brain Study

 

The landmark 1968 work refers to experiments by Roger Sperry and his student Michael Gazzaniga, conducted at the California Institute of Technology. These studies became some of the most famous demonstrations of hemispheric specialization.

Louis-Antoine Ranvier

 

 Louis-Antoine Ranvier (1835–1922) was a French physician, anatomist, and histologist. He worked during a period when microscopy was transforming biology and medicine.

Nodes of Ranvier (1878)

His most famous discovery was the identification of periodic gaps in the myelin sheath of nerve fibers.

Key observations:

• Myelin is segmented, not continuous

• Gaps occur at regular intervals

• These interruptions later proved essential for saltatory conduction
