Question
Chapter 9.3, Problem 11CC
Summary Introduction
To determine: The observation made by Ehrlich in his experiment of dyeing cerebrospinal fluid (CSF) and other body tissues.
Introduction: The brain, present in the cranium, is surrounded by an aqueous layer of fluid that is called the cerebrospinal fluid. The cerebrospinal fluid or CSF works to provide vascular connection and protection from the physical and chemical stress.

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.

Specifically, you’ll choose an empirical study (2020 or earlier) that was featured in news reports and critically evaluate its presentation there in light of the original research paper. The topic is about visual perception in animals or humans . We already spoke about mantis shrimp so that example is not available however it can be any other animal.arrow_forward
- Juliette lost her left thumb in an accident. Now, whenever she pushes her hair off her forehead, she feels as though she is touching her left thumb, which she no longer has. What best explains what has happened in the area of Juliette’s brain that processes sensation in the body to lead to the phantom sensation. Question 5 options: a) Old memories of sensations related to brushing her hair back simply reassert themselves even though the thumb is no longer present b) Sensory neurons from the scar tissue overlying the stump of the amputated thumb have become hypersensitive to touch sensations c) Sensory neurons that received input from the thumb now respond to input from surrounding cells that receive input from the rest of the hand d) Neurons from the left side of the neocortex serving the right thumb have taken over control of the neurons on the right and are activated by the…arrow_forwardWhich of the following is an illustration of experience-dependent plasticity?

- Tactile acuity refers to the minimum separation required between two objects for the brain to perceive them as two separate points. The Two-Point Discrimination test is one method used to measure tactile acuity. A two-pronged instrument such as a bent paperclip is pressed at various locations on the body. The distance between the two ends is increased gradually until the person feels two distinct points. This distance is then measured. The less the distance that two points can be perceived separately, the higher the tactile acuity of that area. When comparing the tactile acuity of various body parts, what have you concluded about the number of receptors in the palm of your hand relative to the number of receptors on your shoulder? a. The tactile acuity for the palm is higher than for the shoulders. Therefore, more receptors are found on the palm than on the shoulders. b. The tactile acuity for the shoulders is higher than for the palm. Therefore, more receptors are found on the…arrow_forwardOzana was born with cataracts, which made her completely blind. When she was 14 years-old she underwent surgery to remove the cataracts, which allowed visual input to be transmitted to her brain for the first time.
