Midterm: People in Neuropsych

Question 1

Hermann von Hemlholtz:

Answer 1

first to measure speed of nerve conduction; tricolor theory; physics of color and sound

Question 2

Wilder Penfield:

Answer 2

homunculus; first neurosurgeon; worked with epileptic patients and discovered brain consisted of different regions

Question 3

Paul Broca:

Answer 3

localization of language and lateralization (+ specialized functions)

Question 4

John Hughlings Jackson:

Answer 4

distributed hierarchy in sensory and motor systems; Jacksonian focal seizures. motor homunculus

Question 5

Ramon Y Cajal:

Answer 5

staining technique; neurons are autonomous and functional specialization. Disproved Golgi’s “nerve net”

Question 6

Eduard Hitzig:

Answer 6

showed that the brain conducts its own electrical activity

Question 7

Thomas Willis:

Answer 7

termed blood flow in the brain “Circle of Willis;” coined “psychology;” wrote first textbook; cortex associated with memory; cerebellum related to motor control

Question 8

Franz Gall:

Answer 8

phrenology

Question 9

Roger Sperry:

Answer 9

split brain patients (cut corpus callosum- epilepsy); corpus callosum functions in more than structural support

Question 10

Karl Lashley:

Answer 10

recognized scotomas in the onset of a migraine; tried to find out location of memory and learned habits. mass action (learning depend on amt of cortex) and equipotentiality (one part of cortex can take over function of another part)

Question 11

Galvani:

Answer 11

frog leg muscles and electrical patterns (stimulate nerves via electrical activity); axons covered in fat (myelin)

Question 12

Bell and Magendie:

Answer 12

spinal cord has two tracts- dorsal (incoming sensory information) and ventral (outgoing motor information)
