Exam 3: Section 4: Neuroscience and Behavior

Genes are comprised of chromosomes.

Damage to the occipital lobe can result in partial or complete blindness without any damage to the eyes.

Glial cells form the nucleus of the cell body.

After his corpus callosum was severed to treat a seizure disorder, Phineas Gage experienced a progressive decline in personality and emotional stability.

During an action potential potassium gates open, allowing potassium to rush into the cell.

Lesions to some areas of the hypothalamus may result in overeating.

Of the three major types of neurons, the majority of the neurons in the nervous system are interneurons.

The split-brain procedure is a last-resort surgical procedure to treat extreme cases of schizophrenia.

The size of the area corresponding to a body part in the somatosensory cortex depends on how critical that part is for survival.

Brain imaging techniques have revealed that phantom limb syndrome occurs when areas in the hippocampus are stimulated, triggering memories of the missing limb.

At rest, the outside of a neuron is more negatively charged relative to the inside of the neuron.

The thalamus is part of the limbic system.

The spinal cord is the major component of the peripheral nervous system.

Low levels of dopamine have been linked to schizophrenia.

The wrinkled nature of the cortex necessitated evolutionary adaptations, including the growth of the human skull.

The temporal lobe contains the somatosensory cortex.

CT scans provide a much higher resolution of anatomical detail than do MRI scans.

Humans have 23 pairs of chromosomes.

Epigenetics refers to how the environment may alter gene expression by changing the underlying DNA sequence comprising the gene.

Alzheimer's disease is associated with the deterioration of the myelin sheath covering the axon.
