Exam 2: The Brain, the Body, and Behavior

The inferior and superior colliculi are both parts of the

Without a thalamus, your cortex would still be able to process sensory and motor information properly.

During an action potential, the cell becomes _______________ meaning that a flood of sodium (Na⁺) ions enter the cell, raising its electric charge.

The anatomy of the neuron includes four very important regions: dendrites, cell body, axon, and terminal. Define each region and explain how each region contributes to an action potential.

Which of the following provides the best description of hemispheric specialization in the cortex?

The ____________ lobe houses the somatosensory cortex and the ______________ lobe is dedicated totally to visual processing.

Also known as the "reward center" of the brain, these dopamine-rich nuclei provide the motivation to engage in rewarding behavior.

You meet a patient in the hospital who has experienced head trauma that disrupted the function of her primary visual cortex. Which lobe of the cortex has been affected?

Which of the following best describes the flow if information in visual cortical areas?

When a drug increases the effect of a neurotransmitter is called a(n)

In general, neurotransmitters can bind to any receptor on any dendrite regardless of the size and shape.

The human brain is able to reorganize and adapt to environmental input, a concept known as

The phrase "ghost in the machine" is most associated with

This part of the hindbrain is important for functioning of your vital organs.

Axons that make up the white matter of the brain and spinal cord are surrounded by myelin, cells that accelerate the speed of neural communication.

These cells vastly outnumber other neurons and function to pass messages between neurons.

This outer layer of the cerebrum enables humans to interpret sensory information, solve problems, learn, remember, and use language.

GABA tends to produce relaxation and sedition because its action is

These circuits of neurons in the spinal cord are the reason why infants will execute walking movements if placed on a treadmill.

The cells that send information to the muscles and organs of the body are called
