Question

Considering a cortical motor neuron with a directional specificity that is downwards, ALL the statements below as true or false and explain.

A. The figure above shows that the neuron increased its firing rate over time.

B. The figure above represents the net activity of all neurons observed and the neuron in question probably decreased its firing rate over time.

C. The population activity of the neurons observed becomes organized as I determine the direction in which I should move.

D. This figure shows the preferred direction of a neuron.

E. The length of each line represents the neuron’s firing threshold.

Explanation / Answer

A. The figure above shows that the neuron increased its firing rate over time. FALSE

As seen from the figure the neuron dont have a steady increase firing rate over time. rather it has increased for a time from its origin, then decreased and finally has maintained a probably constant rate of firing.

B. The figure above represents the net activity of all neurons observed and the neuron in question probably decreased its firing rate over time FALSE

It is true that it represents the net activity of all neurons but firing rate is not continuously decreasing.

C. The population activity of the neurons observed becomes organized as I determine the direction in which I should move.TRUE

D. This figure shows the preferred direction of a neuron.FALSE

There is nothing specified as preferred.

E. The length of each line represents the neuron’s firing threshold. TRUE
