Which of the following statements best describes the path of visual information in the brain? Visual information from the left half of each eye travels to the brain's right side.
How does the brain process visual information quizlet?
How do the eye and brain process visual information? After processing by bipolar and ganglion cells in the eyes' retina, neural impulses travel through the optic nerve, to the thalamus , and on to the visual cortex. In the visual cortex, feature detectors respond to specific features of the visual stimulus.
Which has the most direct route to the brain?
How does a cochlear implant operate? sense of smell , has the most direct route to the brain, as the only sense bypassing the thalamus.
What detects temperature and then sends information about temperature to the brain?
The hypothalamus also has temperature receptor cells which detect changes in the temperature of the blood flowing through the brain. If the temperature is above or below 37°C, the hypothalamus sends electrical nerve impulses to effectors , which are mainly found in the skin.
Which of the following is the reason why you can see different colors?
Our brain is responsible for deciding what color we are seeing based mainly on one factor: the light that comes through our eyes . White light is composed of radiation of all colors. When an object receives light, it absorbs some wavelengths and reflects others. The ones it reflects are the ones we see as color.
How does the brain process visual information?
Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the brain.
How visual information is transmitted to the brain?
The optic nerve , composed of the axons of the retina's ganglion cells, then transmits these impulses from the eye to the first visual relay in the brain. ... The optic nerve is the pathway that carries the nerve impulses from each eye to the various structures in the brain that analyze these visual signals.
When Petra jumps into a cold lake she feels as though?
When Petra jumps into a cold lake, she feels as though she is freezing. After a few minutes, she no longer notices the cold and feels comfortable in the water. This change is an example of? The process by which a sound is transformed into a neural signal involves which of the following sequences of transformations?
Are the basic building blocks of the nervous system?
A neuron is a nerve cell that is the basic building block of the nervous system. ... Neurons are specialized to transmit information throughout the body.
Which of the following facts support the trichromatic theory of color vision quizlet?
Which of the following facts support the trichromatic theory of color vision? We have more trouble visualizing reddish green than reddish yellow . After staring at a yellow spot, a person sees a blue afterimage. The eye contains three types of cone cells, activated by short, medium, and long wavelengths.
What part of the brain detects temperature?
Our internal body temperature is regulated by a part of our brain called the hypothalamus . The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
What part of the brain detects body temperature?
The hypothalamus helps keep the body's internal functions in balance. It helps regulate: Appetite and weight. Body temperature.
What happens to enable you to see something?
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals . These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
Do we see color differently?
We sometimes think of colors as objective properties of objects, much like shape or volume. But research has found that we experience colors differently , depending on gender, national origin, ethnicity, geographical location, and what language we speak. In other words, there is nothing objective about colors.
What is blind color?
Color blindness occurs when you are unable to see colors in a normal way . It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues.
How do we see Colour?
Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
