Exam 4: The Brain and Nervous System

Which of the following lobes of the brain is involved in the ability to do a series of tasks in proper sequence and then to stop doing these tasks at the proper time?

The parietal lobes are at the sides of the brain, just above the ears and behind the temples.

One of the functions of a nervous system is to gather and process information.

Coin-shaped electrodes are pasted onto Miranda's scalp, and they are connected by wires to a machine that translates the electrical energy from her brain into wavy lines on a monitor. From this description, it is evident that Miranda's brain is being studied with the help of:

Which part of a neuron acts like an antenna to receive messages from other neurons and transmit these messages toward the cell body?

Functional MRI can tell where something is happening in the brain better than an EEG.
