Young 6 Ivan Petrovich Pavlov MD 1849-1936 • Born in a Central Russian farming village, Ryazan. Father was a Russian orthodox priest-expected Pavlov to enter into local seminary • Received free education (primary and seminary) made possible by Czar Alexander II for gifted/poor students • In seminary, he read Darwin “Origins” and Ivan Sechenov’s “Reflexes of the Brain” • Left seminary (without graduating), enrolled at the Univ. of St. Petersburg where he studied Medicine/Natural Science • Sechenov was the Professor of physiology • Graduated in 1875 • Research was his goal, not to practice • Won 2 year fellowship in Germany (/Breslau) investigating circulation and gastric secretion • Studied experimental back in St. Petersburg • Doctorate on centrifugal of the (discovered independently of Gaskel special tropic nerves of the heart 7 • 1891-Professor of Physiology at the Institute of Experimental Medicine • Researched until he died in 1936, he was 86 years old Ivan Pavlov MD

 In 1890s: Digestion . Surgically created dog’s a pouch with a fistula implanted (Pavlov's pouch) in order to observe secretion of gastric juices when dogs began to eat without contamination of food. . These findings about gastric secretions led to the Nobel Prize in Medicine and Physiology in the 1904 book The Work of  Research in 4 Fields: The Digestive Glands (right), published in 1897 in and translated to English in 1. Cardiac physiology 1902. 2. Digestion . In 1907, became full member in the 3. Russian Academy of Sciences.

8 4. Ivan Pavlov MD and The Conditioned Reflex  1897-1900 : Observed the following in the course of gastric reflex research

• Dogs would secrete gastric juices and saliva when saw or heard keeper- initially this was considered a nuisance

• Recognized there must be an explanation since there was no food in the dogs mouth. The dog realized mealtime was near

produced secretions

• A “psychic secretion” is due to a reflex in the brain caused by the of

sight or sound of the person who was 9 usually bringing food.  Early Experiments of the Ivan Pavlov MD Conditioned Reflex • 1902-Began to study how and when such a stimulus was capable of causing secretions.

• Instead of stomach pouch with fistula he implanted a fistula in salivary gland to a collection/recording device

• Dogs trained to stand on the table- praised, pelted or fed

• Faced wall w/ window; bowl of food could be placed in

• When dog had food in it’s mouth-saliva flowed

• FOOD=UNCONDITIONED STIMULUS

• SALIVARY RESPONSE=UNCONDITIONED REFLEX 10 IVAN PAVLOV M.D.

SOUND = CONDITIONED SALIVARY STIMULUS RESPONSE=CONDITIONED REFLEX  Sound (ring, bell, buzzer)  After a number of sequences, in preceded food drop bowl by sound alone caused saliva to flow. various amounts of time, usually 5 to 30 seconds.

11 1927 Ivan Pavlov MD Conditioned Reflex

 Did not believe this was a psychological process-but a physiologic one.  Many variations on experiment  Claimed indebtedness to Descartes and Sechenov  instead of sound  Change length of time between neutral stimulus and food drop  Neutral stimulus could be made into conditioned stimulus w/ varying degrees of ease • Neutral odor might require >20 pairings  Pavlov considered unconditional response a brain reflex • Rotation of object in dogs view might  Conditioned response was a result of new reflexive pathways require >5 pairings created by conditioning process in the cortex12 • Sounding bizarre might require only 1  Early concept Ivan Pavlov MD His Dogs  While he experimented on He erected a stone dog dogs, he took great care of statue in the courtyard of them and loved them. He did the Institute of not destroy them. Experimental Medicine  Considered them man’s best (below) friend and science martyrs

14 Ivan Pavlov MD Anti-Semitism • Attributed negative dimensions of Bolshevism to Jewish influence

• 1928 he complained to Gantt that the occupied “high position everywhere” and that it was “a shame Russians can not be rulers of their own land”

• 1935/1936 when he expressed a more positive attitude towards Bolsheviks he minimized the Jewish presence in the communist party as a “thin stratum”

• 1934/1935 even Pavlov was scolding the Jews and on learning one woman among his listeners was Jewish he said : “Why didn’t anyone warn me?” Lina Stern and Ivan Pavlov among15 the delegates of XIV International Congress of Physiology, Rome 1932 Nobel Prize 1906 Visualizing the Nervous System with New Microscopic Techniques

Neuron Doctrine Structure of Central Nervous System in Birds • Demonstrated relationship between nerve cells was (1905) continuous and showed how nerve cells are connected. • Supported theory (not reticular-Golgi) • Nerve cell is an independent entity • Nerve transfer nerve impulses from one cell to another

21 Santiago Ramón y Cajal MD 1852-1934 “In the intricate warp of the brain one can advance only step by step, and if one is to do so safely, the front trenches must be dug by men like Theodor Meynert, Camillo Golgi, Ludwig Edinger, Paul Emile Flesheig, Albert von Kölliker ,Auguste Forel, and the other great ones…” “I threw myself into the task with the sure faith that in the dark thicket, where so many explorers had been lost, I should capture, if not lions and tigers, at least some modest game scorned by the great hunters.”

• I must state that in the aforesaid lecture I made a cordial eulogy of my colleague, Professor C. Golgi…

• Contrary to what we all expected, he attempted in it to refloat his almost forgotten theory of interstitial nets…

• He made a display of pride and self-worship so immoderate that they produced a deplorable effect upon the assembly…

• I have never understood these strange mental constitutions which are devoted throughout life to the worship of their own egos, hermetically sealed to all innovation…

• What a cruel irony of fate to pair like Siamese twins united by the shoulders, scientific adversaries of such contrasting character!...

• My colleague displayed the same Olympic pride and pretentious mien in his toast at the official banquet… 24 The Beautiful Brain The Drawings by Santiago Ramón y Cajal Edited with commentaries by Eric A.

• Showed olfactory receptors belong to family of -coupled receptors • Analyzed rat DNA & estimated there are approx. 1,000 different genes for olfactory receptors in mammalian • Led to further work of genetic & molecular analysis of mechanisms of olfaction • Each neurons only expresses one kind of olfactory receptor protein • Input from all neurons expressing the Buck, L. and Axel, R.

69 Linda Buck Ph.D. Retracts Papers

• In 2008, Buck had to retract 2001 paper • Inability to produce results “inconsistencies between some of the figures and data published the original data” • Paper in question is tied to the “mapping of olfaction to discrete parts of the brain” • Initial groundbreaking work with Richard Axel still valid • Later retracted PNAS 2005 & Science 2006 papers citing she could not reproduce data of these papers • Buck stated most of questionable date came from post-doc Dr. Zhihua Zou

70 .

A team of including Linda B Buck, who shared the 2004 Nobel Prize in Physiology or Medicine, has retracted a scientific paper after the scientist could not reproduce their original findings.

The Harvard Medical School, where the researchers worked when the findings were published in the journal Nature in 2001, has begun a review of the research to determine if there is any evident of misconduct. 71 .

PNAS Nature

73 May-Britt Moser • Along with her husband Edvard I. Moser in 2005, discovered a type of cell that is important for determining position close to the hippocampus. • Found that when a rat passed certain points arranged in a hexagonal grid in space, nerve cells that form a kind of coordinate system for navigation were activated.

Awarded The Nobel Prize in Physiology or Medicine 2014 “for the discoveries of cells that constitute a positioning system in the brain”.

75 Some Neuro Nobel’s came from humble origins

Many had immigrant backgrounds

Many from USA

Some infamous or have a dark side

Many either fled from the Nazi’s or were a Nazi

Too many men Four women

At least one was accused of subsequent research misconduct and had to retract papers

Still the story of the Neuro Nobel’s is a pillar of western scientific knowledge and
