Unit 2: Cognitive Neuroscience

Which part of the neuron is responsible for receiving information from other neurons?

• Axon

• Dendrite

• Cell body

• Synapse

Answer explanation

The dendrite is responsible for receiving information from other neurons, making it the correct choice.

What is the primary function of the occipital lobe?

• Auditory processing

• Visual processing

• Motor functioning

• Memory formation

Answer explanation

The primary function of the occipital lobe is visual processing, which involves interpreting visual information from the eyes.

Which neurotransmitter is most likely to decrease the chance that a neuron will fire?

• Excitatory neurotransmitter

• Inhibitory neurotransmitter

• Dopamine

• Acetylcholine

Answer explanation

The most likely neurotransmitter to decrease the chance that a neuron will fire is an inhibitory neurotransmitter, as it inhibits or reduces the likelihood of neuron firing.

Which technique measures blood flow to areas of the brain to indicate levels of brain activity?

• EEG

• MRI

• PET Scan

• TMS

Answer explanation

PET Scan measures blood flow to areas of the brain to indicate levels of brain activity.

Which part of the brain is involved in forming new memories?

• Hypothalamus

• Amygdala

• Hippocampus

• Thalamus

Answer explanation

The hippocampus is the part of the brain involved in forming new memories.

The frontal lobe is responsible for visual processing.

• True

• False

Answer explanation

The frontal lobe is not responsible for visual processing. It is responsible for functions such as decision-making, problem-solving, and emotions.

Neurotransmitters cross the synapse and bind with the receiving dendrites.

• True

• False

Answer explanation

Neurotransmitters crossing the synapse and binding with the receiving dendrites is a true statement.

Action potentials vary in size depending on the intensity of the stimulus.

• True

• False

Answer explanation

Action potentials do not vary in size depending on the intensity of the stimulus. They are all-or-nothing responses that do not change in magnitude.

The primary function of the thalamus is to process emotions and emotional memories.

• True

• False

Answer explanation

The correct answer is False. The primary function of the thalamus is not to process emotions and emotional memories, but rather to relay sensory and motor signals to the cerebral cortex.

Broca’s area is involved in language comprehension.

• True

• False

Answer explanation

Broca's area is actually involved in language production, not comprehension. Therefore, the correct answer is False.
