Early in an action potential, the inside of the axon becomes less negatively charged relative to the outside, this is called. Polarization Depolarization Hyperpolarization Repolarization ---------------------------------- Neurotransmitters -gated (ligand gated) ions channels are important for ____, while voltage gated ion channels are important for ____ Communication between neurons; communication within neurons communication within neurons; Communication between neurons ------------------------------- In gross neuroanatomy we are interested in structures that are NOT visible to the naked eye. True or false.
The purpose of an action potential (AP) is to propagate a signal down the axon to the axon terminal. What happens once it reaches the axon terminal? Using the experiment showing recordings from the post-synaptic cell (endplate potentials), describe what happens when an AP reaches the axon terminal and subsequently transmits the signal to a neighboring cell. What does this tell us about chemical neurotransmission?
Name the major parts of an axon.
1) The interior of an axon at rest is negatively charged relative to the outside is positively charged relative to the outside has the same charge as the outside has the same concentration of potassium (K+) as the outside 2) The branch-like portions of a neuron that carries information toward the cell body is the axon. dendrite. terminal button. soma.
When they are not being stimulated, neurons have an electrical charge across their membranes called the resting potential. 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.
Why does an action potential move in an all-or-nothing fashion down the length of an axon without stopping?
Neuron A is an inhibitory neuron that is activated when the person feels heat in the tip of their index finger. Neuron A sends signals to neuron B (the postsynaptic neuron). First consider how a stimulus impacts the firing rate of neuron A. For example, when the person touches ice with their index finger vs. when the person touches a hot cup of coffee with their index finger? How would each of these impact the frequency of action potentials, the size of action potentials and the amount of neurotransmitter released. Second, consider Drug-D that causes all sodium channels in neurons to close immediately. How would taking Drug-D affect the firing rate of neuron A when the person touches a hot pan? In turn, how would this affect the firing rate of post-synaptic neuron B? Rubric: Impact of heat on A Impact of ice on A ( Impact of drug X on A Impact of drug X on B 1
"Hebb's Rule" says, in effect, that a neuron that is repeatedly activated will have an increasingly powerful effect on all of its neighbours. neurons that are repeatedly activated together become more strongly connected. neurons that are strongly connected are likely to become activated at the same time. neurons that are strongly connected are typically found in the cortex.
In and around the axon, where is the higher concentration of sodium ions? Where is the higher concentration of potassium ions? What maintains this gradient?
