Q

(Amnesia/Memory decline/Memory deficit) is defined as a significant difference between one’s IQ and declarative memory.

A

Amnesia

22
Q

In contrast to many brain regions that do not lose appreciable numbers of neurons throughout life, 15-20% of the neurons in the ___________ and ____________ may be lost in old age.

A

Neostriatum and prefrontal cortex

23
Q

Increasing numbers of neurofibrillary tangles appear with age in the ____________ beginning in the fifth decade of life.

A

Hippocampus

Alzheimer’s

24
Q

(Anterograde/Retrograde/Source) amnesia is the inability to recall context in which memories are formed.

A

Source

25
Q

(Anterograde/Retrograde/Source) amnesia is the inability to learn or recall new information.

A

Anterograde

26
Q

(Anterograde/Retrograde/Source) amnesia is the inability to recall previously learned information.

A

Retrograde

27
Q

A traditional view of amnesia attributes memory loss to damage within a functional circuit comprised of the hippocampus, fornix, and mammillary bodies known as the ___________.

A

Papez circuit

28
Q

Paul McLean revised the Papez circuit to include the ____________ and __________.

A

Amygdala and hypothalamus

29
Q

(T/F) The amygdala and hippocampal formation receive direct inputs from the olfactory, gustatory, and general visceral afferent systems.

A

True.

30
Q

(T/F) Inputs from modalities such as vision, audition, and somatic sensation gain direct access to the amygdala and hippocampus after leaving the cortical association areas.

A

False. These modalities must first project to the orbital, insular, and perirhinal cortices, and then to the entorhinal cortex and amygdala before gaining access to the hippocampus.

31
Q

The (dentate gyrus/subiculum/hippocampus) is the major source of output in the hippocampus formation.

A

Subiculum

32
Q

Injury to the basal forebrain (nucleus basalis) may cause ____________ or ___________.

A

Amnesia or Alzheimer‘s disease

33
Q

Basal forebrain (nucleus basalis) damage may also occur from aneurysm of the (anterior/middle/posterior) cerebral artery.

A

Anterior Cerebral Artery (ACA)

34
Q

Precommissural fibers of the fornix terminate in the (mammillary bodies/septal nuclei).

A

Septal nuclei

35
Q

Postcommissural fibers of the fornix terminate in the (mammillary bodies/septal nuclei).

A

Mammillary bodies

36
Q

Long-lasting synaptic change in response to brief, high-frequency stimulation is referred to ___________________.

A

Long term potentiation (LTP)

  • In hippocampus
37
Q

The inferior (occipital/parietal/temporal) lobe, especially the ____________, is particularly vulnerable to epileptic seizures.

A

Temporal; hippocampus

38
Q

(T/F) Temporal lobectomy, resection of the hippocampi, or damage to the hippocampal formation may only result in anterograde amnesia.

A

False. Removal or damage of the hippocampi or other associated structures in the temporal lobe may result in both anterograde and retrograde amnesia.

39
Q

What are the three major aspects of the memory profile in Alzheimer’s patients?

A
  • Severe explicit memory deficit due to poor encoding and consolidation after extensive damage to the hippocampal-amygdala complex.
  • Partial implicit memory deficit (priming) for verbal and visuoperceptual material reflecting damage to lexical-semantic system and damage to cortical association areas.
  • Spared implicit memory for visuomotor skills suggests integrity of primary motor and sensory cortex and basal ganglia.
40
Q

Patients with (right/left) medial temporal lesions have difficulty retaining verbal material (prose, word lists, verbal paired associative learning).

A

Left medial temporal lesions

41
Q

Patients with (right/left) medial temporal lesions have difficulty learning nonverbal, patterned stimuli like geometric figures, faces, tonal patterns, and visual and tactile mazes.

A

Right medial temporal lesions

42
Q

The (dorsomedial/anterolateral) temporal lobes are thought to play an important role in the storage and retrieval of past autobiographical memories.

A

Anterolateral

43
Q

After receiving input from the fornix, the mammillary bodies project to the (ventromedial/ventrolateral/dorsomedial/anterior/dorsolateral) thalamic nucleus.

A

Anterior thalamic nucleus

44
Q

After receiving input, the amygdala projects to the (ventromedial/ventrolateral/dorsomedial/anterior/dorsolateral) thalamic nucleus.

A

Dorsomedial thalamic nucleus

45
Q

Patients with severe cases of Wernicke-Korsakoff disease have a history of chronic alcoholism. After recovery, these patients may exhibit severe (anterograde/retrograde/source) amnesia. This is known as Korsakoff’s amnesia.

A

Anterograde

46
Q

Korsakoff‘s amnesia typically results from damage to the (mammillary bodies/dorsomedial nuclei/both).

A

A bit of a trick question. Korsakoff’s amnesia may result from damage to mammillary bodies, the dorsomedial nuclei, OR both.

47
Q

(T/F) In addition to damaged mammillary bodies, dorsomedial nuclei, or in some cases, both structures, patients suffering from Korsakoff’s amnesia may also display damage in the medial pulvinar and lateral dorsal nuclei, the cerebral cortex, the cerebellum, the hippocampus, and the fornix.

A

True.

48
Q

Frontal lobe lesions may result in (anterograde/retrograde/source) amnesia, along with difficulty ordering events in time.

A

Source amnesia

49
Q

In recent murine testing, lesions of the (hippocampal formation/amygdala/striatum) have abolished punishment and reward instincts.

A

Amygdala

50
Q

In recent murine testing, lesions of the (hippocampal formation/amygdala/striatum) have abolished habit learning.

A

Striatum (caudate and putamen)

51
Q

In recent murine testing, lesions of the (hippocampal formation/amygdala/striatum) have abolished spatial memory.

A

Hippocampal formation

52
Q

What two structures are shown to have iconic memory traces in visual perceptions?

A
  • Retina
  • Lateral geniculate
