Perception Influence on Noradrenaline

Researchers found a connection between the hormone noradrenaline and perception of images. It was found that people with higher levels of noradrenaline in their systems were able to discriminate low quality images better. What the researchers attempted to figure out was whether if noradrenaline and an effect on sensory perception and if noradrenaline improved perception of images. Noradrenaline plays a role in the late processing of the cerebral cortex. Therefore, it would determine whether the image would be brought back into the person’s memory. Typically, noradrenaline is expressed during arousal but there are more functions to the neurotransmitter that was found.
