Recording an action potential as it travels down an axon.
(a) When the nerve is at rest, there is a difference in
charge, called the resting potential, of _________ between the inside and outside of the axon. The difference in charge between the recording and reference electrodes is fed into a computer and displayed on a computer monitor. This difference in charge is displayed on the right. (b) As the nerve impulse, indicated by the red band, passes the electrode, the inside of the fiber near the electrode becomes more positive. (c) As the nerve impulse moves past the electrode, the charge in the fiber becomes more negative. (d) Eventually the neuron returns to its resting state.
−70 millivolts (mV)
(a) This value, which stays the same as long as there are no signals in the neuron, is called the ________. In other words, the inside of the neuron has a charge that is 70 mV more negative
than the outside, and this difference continues as long as the neuron is at rest.
resting potential
Shows what happens when the neuron’s receptor is stimulated so that a _________ is transmitted down the axon. As the impulse passes the recording electrode, the charge inside the axon rises to_________ compared to the outside
nerve impulse
+ 40 millivolts,

second).
read
(a) Early work on neural representation and cognition focused on recording from single neurons in the visual cortex, where
“signals first arrive at the cortex”.
(b) Researchers then began to explore other places in the brain and found that “visual stimulation” causes activity that is distributed across many areas of the cortex.
(c) Recent work has focused on looking at how these distributed areas are connected by neural networks and how activity flows in these networks. Note that, except for the visual area in (a), the locations of the areas in this figure do not represent the locations of actual areas. They are for illustrative purposes only.
