What is artistic and creative abilities?
The _____ is the transparent front part of the eye that helps to focus incoming light onto the retina.
What is the cornea?
Light-sensitive cells known as rods and cones are primarily located in the _____, which plays a key role in the initial processing of visual information.
What is the retina?
The _____ _____ of function refers to the specialization of each hemisphere for certain cognitive functions or tasks.
What is lateralization of function?
What is the term for the smallest noticeable difference between two stimuli, often referred to as the "just noticeable difference"?
What is the difference threshold?
What is the name for the bundle of nerve fibers that connects the two brain hemispheres, allowing them to communicate and share information?
What is the corpus callosum?
What is the term for the small, adjustable opening in the center of the iris that regulates the amount of light entering the eye?
What is the pupil?
When light enters the eye, the first structure it encounters is the _____, which bends and focuses the light.
What is the cornea?
The _____ _____ is the bundle of nerve fibers that connects the two hemispheres of the brain, allowing them to communicate.
What is the corpus callosum?
The concept of _____ _____ helps us understand how our sensitivity to stimuli can change depending on our state of adaptation.
What is sensory adaptation?
When the left hemisphere of the brain is dominant for language processing, it is referred to as _____ _____.
What is left-hemisphere dominance?
The _____ is the structure in the eye that changes shape to focus light on the retina, allowing us to see objects at different distances.
