Multiple Choice

What role does the basal ganglia play in reinforcement learning?

• It creates a neural map of the environment.

• It refines motor output through sensory prediction.

• It adjusts behavior based on rewards and punishments.

• Sensory prediction

• Reward prediction

• Exploratory learning

• Emotional reinforcement

Why is the brain’s topographic organization considered efficient? Select all that apply then submit your answer.

• Motor and sensory areas overlap to create flexible responses.

• Adjacent brain areas generally control adjacent body parts.

• Sensory and motor cortices are positioned closely.

• Brain areas are mapped predictably, like a remote control.

Multiple Select

• Hearing other people’s accounts of the event

• Lack of emotional intensity

What does the case of H.M. reveal about memory systems in the brain? Select all that apply then submit your answer.

• The hippocampus is required for forming new declarative memories.

• Working memory is processed separately from long-term memory.

• Procedural and declarative memory rely on different brain regions.

• Using procedural memory requires conscious recall.
