Exam 2: Neuroscience and Behavior

Identify and explain several ways in which drugs can affect brain activity by interfering with synaptic transmission.

Tom, a split-brain patient, is seated in front of a screen. As he focuses on the middle of the screen, the image of an apple is briefly flashed on the LEFT side of the screen. Tom will:

Describe the procedure used for testing split-brain patients and explain what the findings of this research demonstrate about the different functions of the left and right hemispheres.

The medulla, the pons, and the cerebellum make up the midbrain.

Because the drug naloxone acts as an agonist at opioid receptor sites, it prolongs and intensifies the effects of both endorphins and opioids.

In myelinated axons, where are the sodium ion channels concentrated?

A new brain-scanning technique called diffusion spectrum imaging allows neuroscientists to produce three-dimensional images of the neural pathways that connect one part of the brain to another.

When a neuron is in the resting potential state:

Diffusion spectrum imaging can produce three-dimensional images of the neural pathways that connect one part of the brain to another. These neural pathways, made up of bundles of myelinated axons, are sometimes called:

This image depicts the left hemisphere of the cerebral cortex. Which area processes information about body sensations and contains the somatosensory cortex?

As a general rule, communication within a neuron progresses from the:

What evidence supports the notion that the human brain seems to benefit from a stimulating environment?

How does communication in the endocrine system differ from communication in the nervous system?

Which of the following drugs is chemically similar to the endorphins?

The structural organization of the human brain is unique and different from all other animal species, including primates.

The drug called L-dopa:

Briefly describe the functions of the different subdivisions of the peripheral nervous system.

Samuel suffered damage to his temporal lobes during an operation to remove tumors from his brain. He is likely to have problems with his:

The popularity of phrenology triggered scientific interest in which of the following?

Pierre Paul Broca and Karl Wernicke helped demonstrate that speech and language functions are lateralized.
