Please find the answer to all three questions   In the ERP Technique, Latency refers to to The number of neurons working together  The time from the onset of a stimulus to the peak of a particular component  The size of electrical change in microvolts of a particular component  The number of trials averaged together  ------------------------- Perception occurs at/in  The sensory receptors  Afferent neural pathways  The brain  The peripheral nervous system    -------------------------   fMRI has better spatial resolution than EEG True  False ------------------------- ERP has better spatial resolution than single unit recordings  True False

Can measures of sensory acuity be obtained through filaments and biothesiometer? Explan why or why not Do you tink changing the frequency of the biothesiometer vibrations would affect your measured results? Why? Which settings affect the frequency of stimulation, which affect amplitude

Required information ◄30s REFLEX ARC Skin Sensory receptor Stimulation of a sensory receptor results in the transmission of an afferent impulse along the axon of a sensory neuron. These axons end in the spinal cord. most cases, the impulse will then travel through an interneuron within the spinal cord to synapse with a motor neuron. 0:00 1:09 Sensory stimuli enter the spinal cord via Multiple Choice Sensory receptors Efferent axons Afferent axons Interneurons 1x 23

Light sensitivitylabel the discussions with titlesDiscussion 1 – Answer in 100 – 150 WordsThere is a relationship between eye color and sensitivity to light. What is that relationship exactly and what causes some color eyes to be more sensitive than others? Discussion 2 – Answer in 100 – 150 WordsExplain the process of perception. Discussion 3 – Answer in 100 – 150 WordsDo humans actually have a “blind spot?” If so, what causes this blind spot and what are some disadvantages of it? Discussion 4 – Answer in 100 – 150 WordsThoughts? Discussion 5 – Answer in 100 – 150 WordsRefer to Figure 3.25 (b) in Ch. 3 of Sensation and Perception. Typically, the right side of the body is controlled and interpreted by the left hemisphere of the brain, and vice versa. How is this different in the visual system? Why? Discussion 6 – Answer in 100 – 150 WordsDescribe the role of light receptors…

Discuss the concept of thought-controlled input devices and their potential in medical applications and assistive technology. What ethical considerations arise when using thought-controlled devices?

Question 14 of 190 FINAL - Science The question is based on the following passage. Although most animals and some plants detect and respond to sound vibrations, the precise sensitivity that we call hearing is rare in the living world. It is highly developed only in birds and mammals, and the same operational system applies in all vertebrate auditory systems. Sound waves cause a liquid within the organism's auditory apparatus to vibrate. These vibrations are picked up by receptors that transmit signals to nerve cells. These cells then communicate the sound to the brain. Humans can hear vibrational frequencies of 20 to 20,000 cycles per second; cats respond to frequencies of up to 50,000 cycles per second; and porpoises and bats pick up frequencies of 100,000 cycles per second. Which statement does the passage support? A. Cats and porpoises are adapted to hearing low frequencies. B. Some frequencies are beyond the human hearing range. C. Ears are damaged by high frequencies. D. Humans…

HELP ME TO ANSWER ALL THE QUESTIONS CORRECTLY PLS

Please help with this question i’m stuck, thank you so much!!

Q.No.3. The goal of a mechanism description is to make the readers confident that they have all the information they need about the mechanism. Write down the description of human eye in detail.

What were the research of William Kaelin, Peter Ratcliffe and Gregg Semenza on shedding light on how cells sense and adapt to oxygen availability. Please explain briefly

1. How would you modify this experiment so that the mass lifted by the muscle contraction continues to increase for every trial?   2. A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.  Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain).

Which of the following statements is correct regarding the experiments performed by Roger Payne? The fact that the owl failed to strike the mouse, but struck the leaf tied to it suggests that the owl was using acoustic cues for target localization. а. b. They supported the conclusion that the owl used thermal detection to hunt because the owls still struck a dummy target made of a leaf which was colder than the surrounding ground. С. The arena filled with sand had scattered leaves in it to mimic the owl's wild habitat. d. Their results remained inconclusive as to whether the owls used their sense of smell because the dummy target made of a leaf which the owls struck did not have any distinct smell. Between a moving leaf on sand vs a moving mouse on sand, the owl would strike them both equally as targets. е.

Like cameras for photography and videography, the temporal and spatial resolutions can be very important in human brain imaging. Which if the following is true regarding temporal and spatial resolution for brain imaging methods? O MEG & especially EEG have better spatial resolution (collect better location information) compared to FMRI and PET, and human brain imaging has generally good spatial resolution compared to non-human methods. MEG & especially EEG have better temporal resolution (collect at a higher rate in time) compared to FMRI and PET, and that first set of methods can be on par with non- human methods in terms of quality of temporal resolution.

Please ASAP> Thanku Which of the following statement about the eye is false: a.Retinal ganglion cells are the only cell type in the retina which fire action potential b.Rods are concentrated in the periphery of the retina c.Cones are concentrated in the fovea d.Cones are very sensitive to dim illumination

Practice 56 Which statement is true? The intensity of a stimulus is encoded by the adaptation of the action potentials. The intensity of a stimulus is encoded by the amplitude of the action potentials. The intensity of a stimulus is encoded by the duration of the action potentials. The intensity of a stimulus is encoded by the frequency of the action potentials.

Please answer fast Provide a thorough anatomical description of how the nervous system transforms light energy in the environment into a neural signal that reaches the primary visual cortex (V1, do not go beyond V1). Define the concept of “receptive field” and describe how the receptive fields (or response properties) of the different types of neurons change as information is processed from the retina through primary (V1) visual cortex (be sure to write about retinal ganglion cells in your answer).

Using microelectrodes, a researcher recorded nerve signals in four neurons in the brain . The neurons are called A, B, C, and D in the table below. A, B, and C all can transmit signals to D. In three experiments, the animal was stimulated in different ways. The number of nerve signals transmitted per second by each of the cells is recorded in the table. Write a short paragraph explaining the different results of the three experiment. 09
