How would changes in grey matter (number of connections) and white matter (myelination of the connecting fibers) change how we see the world?
Step by step
Solved in 2 steps
- Define sensation and perception. Do we have direct contact with our world, or is the world as we know it filtered through our senses? How does the way that we perceive the world influence our mental processes and behavior? Do you think that what we perceive is actually “out there,” or is it what our brain perceives? In other words, can we be mistaken about what we see?Marie is playing soccer with her friends. At one point, she is texting her sister instead of paying attention to the game. At that moment, Marie is hit hard in the back of the head with a soccer ball and is knocked unconscious. When she comes to, she explains that she saw flashes of light right when she was hit with the ball. How can you explain this phenomenon? Use the ideas of modality and labeled line coding to explain your answer.Does the brain process mental images in the same way that it processes physical perceptions?
- What are some general similarities in how receptive fields are represented by the nervous system? What advantage does this give us with respect to those senses?Bryan has normal vision and is wearing a special headset that shows a picture of a sailboat to his left eye and a picture of a dog to his right eye. What is Bryan's perception of these images most likely to be? He will only perceive whichever image is presented to his dominant eye. He will alternate between perceiving the sailboat and perceiving the dog. He will perceive the dog and the sailboat overlaid on top of each other. He will perceive parts of the dog and parts of the sailboat combined together in a fashion similar to a puzzle.The phenomenon of “blindsight” is the ability perform reflexive visual movements such as avoiding objects, despite not being consciously aware that an object was present. Can the phenomenon of blindsight be explained in physiological terms, or is it magic?
- When a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression, scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed. So the photoreceptors in the retina were not stimulated even though they were exposed to light. This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking. Select one: a. 3 and 8 b. 2 and 9 c. 5 and 6 d. 1…You are driving at night on a two lane road, and you see a bright light. The light pass through your pupil, and your lens concentrates the light at retina. This stimulates the visual pathway. Your visual association center processes the signal from your eye and determines the lights is from a flashlight that an old lady is holding while crossing the street. Your visual association center sends a signal to your primary motor cortex, which sends a signal down the lateral corticospinal tract. This signal then proceeds down the spinal cord, out the posterior gray horn of the spinal cord, and out the ventral roots of efferent motor neurons. The motor signal travels from the sacral plexus and out towards the sciatic nerve. To answer this question, number the following steps in the correct order starting with the signal exiting the sciatic nerve. Number in order from 1-15 ______The cycle repeats and now many muscle fibers in the gastrocnemius begin to contracts in unison. _____Calcium ions…Which of these is the BEST example of top-down processing? When Sarah listens to someone speaking Spanish, she can easily hear where one words ends and another begins because she is fluent in Spanish. Shane's sense of taste is based primarily on the chemicals that activate receptors on his tongue. John is able to see blue objects because he has cones that respond to short-wavelength light. Tamara's perception of line length is driven primarily by the true length of the line in space.
- M Which of the following presents the elements of a sensory system in the correct order? Select one: Accessory structure modifies energy and sensory nerves transfer activity to central nervous system, thalamus processes and relays activity to cerebral cortex, cerebral cortex transfers input to accessory structures and sensation or perception is produced. Accessory structure modifies energy, receptor transduces energy into neural activity, sensory nerves transfer activity to central nervous system, thalamus processes and relays activity to cerebral cortex, cerebral cortex receives input and produces sensation and perception. Ob. C. External receptors transduce energy into neural activity, sensory nerves transfer activity to central nervous system and relays activity to cerebral cortex, cerebral cortex receives input and produces sensation and perception. O d. Accessory structure modifies energy, receptor transduces energy and thalamus processes and relays activity to the reticular…What are the neural pathways and mechanisms involved in the processing of visual information, and how do they differ from those involved in processing information from other sensory systems such as hearing, taste, and smell?Claude Monet was an artist who was known for his impressionist paintings.
