Brain/behavior Exam 2

Front 1

Electricity

Back 1

Flow of electrons from a high charge to a low charge

Front 2

Negative Pole

Back 2

Source of electrons: higher charge

Front 3

Positive Pole

Back 3

Location to which electrons flow: lower charge

Front 4

Electrical Potential

Back 4

An electrical charge measured in volts; the ability to do work through the use of stored potential electrical energy

Front 5

Volt

Back 5

A measure of a difference in electrical potential

Front 6

Voltmeter

Back 6

A device that measures the difference in electrical potential between two bodies

Front 7

Galvani

Back 7

Concluded that electricity flows along the nerve. Electrical current applied to dissected nerve causes the muscle connected to the nerve to twitch.

Front 8

Galvani: Electrical stimulation

Back 8

Passing electrical current from tip of an electrode through brain tissue, resulting in changes in the electrical activity of the tissue.

Front 9

People that performed electrical stimulation studies?

Back 9

Fritsch and Hitzig (mid-19th century)
Electrical stimulation of the neocortex causes movement (arms and legs)

Bartholow (1874)
First report of human brain stimulation
