You are tasked with devising an experimental approach for studying local spiking interneurones (LSINs) that respond to touch stimulation of the middle legs in locusts. Your experiments need to address three questions: i. Do some or all LSINs receive input from both middle legs? ii. Do some LSINs receive inhibitory tactile input? iii. Do the receptive fields of different LSINs overlap? The recording equipment available to you permits the use of only one recording electrode at a time. Specify and justify your choice of recording site and recording technique (intra- or extracellular), and briefly explain your strategy for addressing questions i–iii.

List four factors that might influence the reaction time to a stimulus .Consider the ruler drop response time test you performed; do you believe it was valid and reliable? Why or why not ? Provide justifications for your answer. [Hints: Here are a few ideas. Will you conduct many tests on the same subjects (that means the people you are testing))? Is it necessary to use averages? Are there any precautions to take? [Are there any variables that must remain constant?]
Single cell recordings in the dorsal stream (parietal areas) tell us about the mechanisms involved in action control. All of the following is true, EXCEPT: a. All listed here are correct b. Neurons in different parietal areas support the link between gaze-centered neurons area to the body-centered neurons c. Some neurons signal whether to move eyes and some neurons signal whether to move hands d. Some neurons in the anterior intraparietal area respond to 3D shapes that vary in size/orientation, but not to 2D shapes e. Some neurons respond based on the position of an object in relation to the hand f. Neurons in the parietal cortex are allocentric and they exhibit activity that reflects learned movements
How can one experimentally differentiate the function of different frontal areas (M1, FEFs, premotor, SMA, PFC) in action control? Answers: a. Examine neural activity using a task design that separates external cue, internal goals, and movement b. Apply TMS to different frontal areas at different time points of a task requiring performance of self-guided and sensory-guided movements c. Separate animals into different groups and lesion different areas and test their ability to control behavior d. Both B & C e. All of these are correct
You touch the skin with two points of a caliper 13 mm apart, and the subject is able to perceive both points. Which of the following are possible explanations? O A. The two points of the calipers were within two different receptive fields, and both primary sensory neurons converged onto the same secondary sensory neuron B. The two points of the caliper were in overlapping receptive fields and lateral inhibition allowed both points to be distinguished C. The two points of the calipers were within two different receptive fields, and both primary sensory neurons converged onto separate secondary sensory neurons. O Only A and B Only B and C
I need help finding a research paper and a news article that evaluates how brain and mind are presented outside the scientific literature. 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.
Which statement about the events of photoreception is false? a) as a rod cell hyperpolarizes, its release of neurotransmitter increases b) there is more Na+ entry into a rod cell in the dark than in the light c) bipolar cells release more neurotransmitter in the light than in the dark d) as a bipolar cell depolarizes, its release of neurotransmitter increases e) when a rod cell releases neurotransmitter the bipolar cell it synapses with hyperpolarizes
You want to record membrane potential changes in axons of neurons that process different types somatosensory information. Which sequence ranks the speed of maximum firing rate from slowest to fastest that you predict you will record a) muscle spindle < cutaneous mechanoreceptor < pain and temperature b) pain and temperature < muscle spindle < cutaneous mechanoreceptor c) cutaneous mechanoreceptor < pain and temperature < muscle spindle d) cutaneous mechanoreceptor < muscle spindle < pain and temperature e) muscle spindle < pain and temperature < cutaneous mechanoreceptor f) pain and temperature < cutaneous mechanoreceptor < muscle spindle
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.
Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.
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.

An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a 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 withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain. question is in bold
