b. Sensory information reaches the hypothalamus, which is responsible for our initial physical reaction, before the amygdala and cortex.
c. Sensory information can reach the amygdala rapidly along routes that are separate from the pathways for information going to the cortex.
d. Sensory information can be transmitted incorrectly when the stimuli is not easily understood.
