- MAKE CONNECTIONS What effect would you expect if you depolarizedthe neurons in the VTA (see Concept 48.3)? Explain.arrow_forwardWHAT IF? Our brain receives more action potentialswhen our eyes are exposed to light even though ourphotoreceptors release more neurotransmitter in thedark. Propose an explanation.arrow_forwardConsider the circuit from Q5 (above). We want to add another inhibitory neuron to this circuit to increase the likelihood that neuron D will have an action potential. With which cell (A, B, C or D) should our new inhibitory neuron make a synapse to make it more likely that the post - synaptic neuron will have anaction potential?The diagram below shows a simple neural circuit with three pre - synaptic cells labelled 'A', 'B' and 'C', and a post - synaptic cell labelled 'D ' (see image below). Assume neurons A and B each have outputs of +2 and neuron C has output of -1.arrow_forward
- Distinguish between innate and learned behavior. Explain how an experiment using optogenetics could demonstrate the concept of “fire together, wire together” Predict whether a given change in receptors or neurotransmitter release is likely to strengthen or weaken a synaptic connection. Hypothesize how a channel or another molecule in a plant or animal would detect outside stimuli such as touch, chemicals, or light. Predict how perturbations in light levels, retinal, opsins, and cation channels in photoreceptors affects the photoreceptor’s membrane potential and neurotransmitter release. Given information about a neuron’s responses to stimuli, hypothesize what its receptive field might be.arrow_forwardWatch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.arrow_forwardDraw a picture of Communication Within the Neuron and describe?arrow_forward
- WHAT IF? Suppose you examine two groups of individuals with CNS damage. In one group, the damage hasresulted in a coma (a prolonged state of unconsciousness). In the other group, it has caused paralysis (a loss ofskeletal muscle function throughout the body). Relativeto the position of the midbrain and pons, where is thelikely site of damage in each group? Explainarrow_forwardVISUALIZE Describe the action taking place at each of the numbered steps in the figure.arrow_forwardWatch this video (http://openstaxcollege.org/l/neurotrans) to learn about the release of a neurotransmitter. The action potential reaches the end of the axon, called the axon terminal, and a chemical signal is released to tell the target cell to do something, either initiate a new action potential, or to suppress that activity. In a very short space, the electrical signal of the action potential is changed into the chemical signal of a neurotransmitter, and then back to electrical changes in the target cell membrane. What is the importance of voltage-gated calcium channels in the release of neurotransmitters?arrow_forward

TTX blocks K channel, and TEA blocks Na Channels. No change in the equilibrium potentail. TTX blocks Na channel and TEA blocks K Channels. The equilibrium potentials become less positive TTX blocks Na channel and TEA blocks K Channels. The equilibrium potential becomes more positive for both TTX blocks Na channel and TEA blocks K Channels. No change in the equilibrium potentail. TTX and TEA blocks Na channel. No change in the equilibrium potentail.arrow_forwardQ:1-How graded potential is generated at dendrites and cell body?
