1965: BRAIN EXPERIMENTS

The video explores the use of electrodes in brain research, highlighting experiments at UCLA and Yale. Chimpanzees play a game to study brain waves, while computers analyze decision-making patterns. Researchers, including Dr. Jose Delgado, identify brain regions linked to emotions and basic drives. Electrodes can also influence behavior by carrying currents into the brain.

What is the primary purpose of placing electrodes inside the brain in the UCLA experiment?

• To record brain activity during a game

• To enhance the intelligence of chimpanzees

• To measure the physical health of the brain

• To train chimpanzees to perform tricks

In the chimpanzee experiment, what is the reward based on?

• The speed of completing the game

• The accuracy of moves

• Winning the game

• Participation in the game

What do computers attempt to decipher from the brain waves during the game?

• The patterns of decision-making

• The level of intelligence

• The emotional state of the chimpanzees

• The physical health of the brain

Which emotions have been linked to specific brain regions through electrode placement?

• Calmness and anxiety

• Love and hate

• Fear and rage

• Joy and sadness

What capability do electrodes provide to scientists when placed in the brain?

• Increasing strength

• Controlling behavior

• Enhancing memory

• Improving vision
