This flashcard set highlights how specific brain regions and network functions relate to mood, motivation, and personality. State networks are responsible for regulating mood and motivation through widespread cortical and neurotransmitter interactions. Connector regions (hubs linking brain modules) are especially vulnerable—lesions here can cause significant cognitive disruption. Finally, damage to the prefrontal cortex can lead to profound changes in personality and judgment, even when other cognitive functions remain intact.

Mood and motivation are attributed to [state/channel] network functions

Mood and motivation are attributed to state network functions

Many different cortical areas play a role; deficits are usually attributed to interference with neurotransmitter pathways

A legion in which location (connector, or hub) is likely to cause the largest disruption in modularity scores?

Connector

Small legions in connectors can have large effects on cognitio

What regions of the brain, if damaged, can cause a complete change in personality and judgement without impairing other cognitive areas?

Prefrontal cortex

(ex: prefrontal cortical damage)

Arousal is attributed to state network functions

(Deficits cannot be localized to one cortical area)

ARAS is not cortical

List the 5 relevant channel networks

Are deficits localizable to discrete cortical areas?

  1. Language

  2. Learning and memory

  3. Visuospatial perception

  4. Executive function

  5. Emotional regulation and social-interpersonal skills

Deficts ARE localizable to specific cortical (or subcortical regions)

Damage to one area doesn’t necessarily affect the others

Emotional regulation and social-interpersonal skills are attributed to [state/channel] network function

Emotional regulation and social-interpersonal skills are attributed to channel network function

Deficits are localizable to the amygdala, orbitofrontal components of the prefrontal cortex, or the cingulate gyrus

(Note: emotional regulation is not mood; mood and motivation are state network functions w/deficits usually due to neurotransmitter interference)

Learning and memory are attributed to [state/channel] network functions

Learning and memory are attributed to channel network functions

Deficits can be localized to the hippocampus/Papez circuit

Channel = can be localized to a specific brain region

Which 3 brain networks have high significance to psych disorders?

  • Central executive network

    • Executive function

  • Salience network

    • Emotional experiences

  • Default-mode network

    • Memory and internal thought

What is the function of the default mode network?

Abnormal connectivity is seen in which psychiatric disorders?

  • Memory and internal thought

    • Reminiscing about the past

    • Planning for the future

Abnormal connectivity in:

  • Alzheimer’s disease

  • Depression

  • Schizophrenia

List the 2 relevant state networks

Are deficits localizable to discrete cortical areas?

  1. Wakefulness, arousal, attention

  2. Mood, motivation

Deficits are not localizable to discrete cortical areas

Cortical damage must be diffuse to affect arousal (ARAS is not a cortical area)

Language deficits can result from damage to which regions?

  • Left hemisphere perisylvian region

    • Includes Broca’s area (production) and Wernicke’s area (comprehension)

  • Pulvinar nucleus of the thalamus

  • Basal ganglia

Describe some of the effects of damage to the prefrontal cortex

Impulsive/automatic behaviors

Poor planning, judgement, decision making

Executive functions are attributed to [state/channel] network function

Executive functions are attributed to channel network function

Deficits are localizable to the prefrontal cortex

Visuospatial perception is attributed to [state/channel] network function

Visuospatial perception is attributed to channel network function

Deficits can be localized to the ventral (temporal) or dorsal (parietal) regions

Deficits in visuospatial perception may be caused by damage to which two neuroanatomical networks?

“What” pathway (ventral pathway, temporal lobe)

“Where” pathway (dorsal pathway, parietl lobe)

Language is attributed to [state/channel] network function

Language is attributed to channel network function

Damage is localizable to the left hemisphere periSylvian region (Broca and Wernicke)
