What is the main function of the insula lobe?

Each hemisphere of the brain is divided into 4 lobes.

The precentral gyrus is located in the parietal lobe.

The postcentral gyrus is responsible for motor control.

What is the main function of the insula lobe?

Which lobe houses auditory centers and receives sensory fibers from the cochlea?

Which type of brain wave is most commonly seen during sleep and originates from the occipital and temporal lobes?

Which brain wave pattern is associated with an active, relaxed brain and is most commonly seen in the frontal and parietal lobes?

Which brain wave pattern is produced with visual stimulation and mental activity, and is most commonly seen in the frontal lobe?

Alpha waves are most commonly seen in the occipital and temporal lobes

Theta waves are produced with visual stimulation and mental activity

Delta waves are also seen in sleep and originate from all over the cerebrum

Theta waves are most commonly seen in the frontal and parietal lobes

Delta waves are associated with visual stimulation and mental activity

Alpha waves are produced with visual stimulation and mental activity

Which category of sleep is characterized by rapid eye movement and the occurrence of dreams?

Which type of brain waves are associated with stages 3 and 4 of non-REM sleep, often called slow wave sleep?

In which category of sleep are theta waves seen?

During which stage of sleep are slow wave prominent?

How often does the sleep cycle repeat in most people per night?

When do people usually awaken naturally during sleep?

During which stage of sleep are breathing and heart rate very irregular?

Which brain region is particularly active during REM sleep and is involved in emotion?

What type of memories does REM sleep benefit the consolidation of?

During REM sleep, breathing and heart rate may be very irregular.

The limbic system, involved in emotion, is very active during REM sleep.

REM sleep benefits the consolidation of nondeclarative memories.

During non REM sleep, what happens to the firing rates of neurons?

What is a benefit of non REM sleep related to memory?

What does non REM sleep allow time for?

Where does memory consolidation occur?

What is the function of nondeclarative memory?

What is the requirement for long term memory?

Memory consolidation occurs in the medial temporal lobe, hippocampus, and amygdala.

Sleep is needed for optimum memory consolidation.

Long term memory can be classified into Nondeclarative and Declarative memory.

Where are the basal nuclei located?

What is the composition of the lentiform nucleus?

What is the function of the basal nuclei?

Basal nuclei are masses of gray matter located in the white matter of the cerebrum.

The corpus striatum is composed of the caudate nucleus and the lentiform nucleus.

The basal nuclei include the subthalamic nucleus of the diencephalon and substantia nigra of the midbrain.

What neurotransmitter is released by the neurons from motor cortex regions of the frontal lobe in the motor circuit?

Which region sends GABA-releasing neurons to the thalamus in the motor circuit?

What is the function of the thalamus in the motor circuit?

What causes Parkinson's disease?

Which tract is affected in Parkinson's disease?

Which neurotransmitter is primarily affected in Parkinson's disease?

Which structure is responsible for the decussation (crossing over) of fibers, allowing each side of the precentral gyrus to control movements on the contralateral side of the body?

Where does somatesthetic sensation from each side of the body project to in the brain?

What happens in severe forms when communication between the two brain hemispheres is severed?

What is the term now preferred to describe the specialization of function in one hemisphere or the other?

Which term is analogous to handedness, suggesting greater competence with one hemisphere than the other?

How do the two hemispheres appear to function according to the concept of cerebral lateralization?

Is cerebral dominance analogous to handedness, suggesting that people generally have greater competence with one hemisphere than with the other?

Is cerebral lateralization the term now preferred to describe the specialization of function in one hemisphere or the other?

Do the two hemispheres appear to have complementary functions rather than one hemisphere being dominant and the other subordinate?

Is the right hemisphere specialized in language, speech, writing, and calculations?

Is the left hemisphere specialized in visuospatial tasks and recognizing faces?

Is cerebral lateralization the concept that suggests each hemisphere is specialized in different functions?

Which hemisphere of the brain is specialized in recognizing faces?

Which hemisphere is specialized in language and writing?

Which type of tasks seem to be performed better by one side of the brain than the other?

True or false: The right hemisphere is specialized in language, speech, and writing?

True or false: The left hemisphere is specialized in visuospatial tasks and recognizing faces?

True or false: Cerebral lateralization suggests that each hemisphere is specialized in different functions?

Which area of the brain is associated with speech and language disorders caused by damage through head injury or stroke?

Where are the language areas of the brain located in most people?

What are aphasias?

Where is Broca's Area located?

Which area does Broca's Area send fibers to?

What is the primary function of Broca's Area?

Where is Wernicke's Area located?

What does Wernicke's Area control?

Where is information about heard words sent by the brain?

Wernicke's Area is located in the left superior temporal gyrus.

Wernicke's Area controls understanding of words (language comprehension).

Information about heard words is sent by the temporal lobe (auditory cortex).

Where does word comprehension originate in the brain?

Where is information about heard words sent by the brain?

Where does Broca's area send information to direct movement of appropriate speech muscles?

Where is the Angular Gyrus located?

What is the main function of the Angular Gyrus?

What happens if there is damage to the Angular Gyrus?

Which type of aphasia involves rapid speech with no meaning, often referred to as word salad?

In which type of aphasia are both Broca's and Wernicke's areas intact, but the damage is caused by the arcuate fasciculus?

Which type of aphasia results from damage in Broca's area and involves slow, poorly articulated speech with no impairment in understanding?
