billion) neurons. Each neuron may communicate with thousands of other neurons in complex information-processing circuits. Recently developed technologies can record brain activity from outside the skull. One technique is functional magnetic resonance imaging (fMRI)‚ which reconstructs a 3-D map of the subject’s brain activity. The results of brain imaging and other research methods show that groups of neurons function in specialized circuits dedicated to different tasks. The ability of cells

The conduction velocity will be the same in both fibers. Stop & Think Questions: 3. Note the difference in time between the action potential recorded at R1 and the action potential recorded at R2. The distance between these sets of recording electrodes is 10 centimeters (0.1 m). Convert the time from milliseconds to seconds‚ enter

Neurophysiology Lab Report Activity 1: 1. What was your observed threshold voltage? The voltage at which I first observed an action potential was 3.0V 2. How does this tracing compare to the one that was generated at threshold voltage? The small increase in voltage causes a small increase in the height of the action potential peak. 3. What reasons can you give for your answer? Recruitment of the nerve’s neurons. Increasing the voltage will cause most of the neural fibers to experience

carbohydrates and proteins into their building blocks so they can be used by the body. Once these molecules are broken down‚ they can become the raw material for the production of the body’s energy currency‚ adenosine triphosphate (ATP). In this activity‚ you will work with your team to design and build a model of the human digestive system. This model will be used to explain the unique structure and function of the parts of the digestive system to a middle school health class. Each structure and

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
