MEMORY A journey from the mind to the molecules -Mr. Arjun Maitra -Assistant Professor Dept. of Physiology PCMS&RC
TO MY STUDENTS HERE I HAVE TRIED TO SIMPLIFY THE HUGE SUBJECT WITH ANIMATIONS, DIAGRAMS, FLOW CHARTS & RELEVENT MCQs. DIFFERENT TEXT BOOKS AND REFERENCE BOOKS HAVE BEEN USED FOR PREPARING THE CONTENTS. SLIDES ARE NOT THE SUBSTITUTE REMEMBERTHESE SLIDES ARE NOT THE SUBSTITUTE OF YOUR TEXT BOOKS ANIMATIONS AND DIAGRAMS ARE COLLECTED FROM DIFFERENT WEBSITE SOLELY FOR EDUCATION PURPOSE.
Eric. R. Kandel (MD) Nobel Prize :2000 (Physiology) Nobel Lecture: The Molecular Biology of Memory Storage: A Dialog between Genes and Synapses
In the Beginning there was... Memory But it soon became apparent that not all memory was created equal… Whats your mothers name? What did you have for lunch today? Yesterday? Two days ago? What color is the car youre parked next to? How do you ride a bike?
