What is the primary function of the nervous system in relation to sensation?

• To transmit signals from the senses to the brain

• To regulate body temperature

• To control muscle movement

• To produce hormones

Which of the following best describes sensation?

• The action taken in response to stimuli

• Simple elementary processes at the sensory system's start

• Complex processes involving interpretation

• The conscious experience of stimuli

What is the term for the transformation of environmental energy into electrical energy?

• Perception

• Sensation

• Neural processing

Which part of the brain is primarily responsible for processing visual signals?

What is the difference threshold?

• The smallest intensity needed for a stimulus to be detected
