Describe the basic pathway of information flow through neurons that causes you to turn your head when someone calls your name.
Step by step
Solved in 3 steps
- a channel can be gated mechanically, voltage or by a ligand. When you hear a sound all three of these type channels are being utilized. Explain generally where/how each of these channels are being utilized starting from hearing the sound, through travelling down a nerve to transmission to another nerve.Using the neurons below, how can you decrease the connection strength (amplitude of EPSP) onto the test cell below? You can only change the properties of the blue neuron. How could you change the properties of the blue neuron to increase the connection strength onto the test cell? What type of plasticity is this? Now, briefly explain how the properties of synaptic plasticity could result in “learned” behaviors such as stopping at a stop sign while driving.You are in the library and just found a place in the reading room. You settle down to study when you get a call and must step outside the library to take the call. After finishing the call you are going back to the reading room and your brain helps you navigate to the location in the library that you chose for yourself. Which one(s) of the following is/are correct? * A.1) The basic neural code involved here is the pattern of neuronal firing rate and its match with the stored pattern in your brain A.2) Your exact spatial locus from different spatial boundaries would be indicated by boundary detecting cells (neurons) A.3) The basic neural code involved here is the pattern of neuronal firing rate and its mismatch with the stored pattern in your brain A.4) Boundary detecting neurons would indicate your outbound path A.5) The place cells (neurons) would index your current position in the…
- Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.The serves as gateway routing all signals coming from brain stem to cerebral cortex - 1)Hypothalamus 2)Thalamus 3)corpus Calilosum 4)cerebrum 5)Corpus CallosumA voltmeter is used to measure the potential difference across a neuron’s membrane. A change in potential difference will occur when an action potential is generated. A neurologist uses a giant squid neuron to study the propagation of an action potential. She places two voltmeters on the axon membrane to measure the potential difference: one near the dendrite and the other at the axon terminal. A stimulus is then applied. Often, the stimulus is applied at one end of the neuron. In this experiment, the scientist decides to stimulate the middle of the neuron. Which statement describes what the scientist would observe at the voltmeters? Select one: a. Both voltmeters will indicate changes to the potential difference. b. No changes to the potential differences will be registered at the voltmeters. c. The voltmeter at the dendrite will indicate a change to the potential difference. d. The voltmeter at the axon terminal will indicate a change to the potential difference.

This potential is______ charged inside. When a neuron receives a sufficiently large stimulus, and reaches a potential called the_______ , it produces an action potential. This causes the neuron to become_____ charged inside.
- the bacterium clostridium tetani produce a toxin called tetanospasmin, the causative agent os the disease tetanus. the toxin prevents the release of inhibitory transmitters in the CNS and so blocks the resulting IPSPs they would normally generate. what are some of the functions of inhibitory synapses? considering this what symptoms would you expect from the disease tetanus, and why? ( hint: imagine trying to stand up if all of the muscles in your lower limb contracted at the same time.)You and your lab partner have prepared a frog nerve for gathering data on action potentials. You connect an electronic stimulator to the nerve and ask your partner to gradually increase the voltage until you see an action potential. Your partner says that the voltage knob is stuck and will not increase the voltage. To finally get an action potential, they begin to trouble shoot and instead of increasing the voltage, they begin to simulate the nerve over and over again and see an action potential. What type of summation is this describing? action potentials graded potentials spatial summation temporal summation O thresholdIn the laboratory, researchers can apply an electrical stimulus at any point along the axon, making action potentials travel in both directions from the point of stimulation. An action potential moving in the usual direction, away from the axon hillock, is said to be traveling in the orthodromic direction. An action potential traveling toward the axon hillock is traveling in the antidromic direction. If we started an orthodromic action potential at the axon hillock and an antidromic action potential at the opposite end of the axon, what would happen when they met at the center? Why?
