PERIPHERAL COMPONENTS OF EMOTIONAL RESPONSE
- PARASYMPATHETIC RESPONSE
- SYMPATHETIC
- HYPOPHISIS-CORTICO-SUPRARRENAL AXIS

A
  • Parasympathetic: vagus nerve with insulin
  • Sympathetic: adrenaline
  • Hypophisis-cortico-suprarrenal: glucocorticoids

Q

Cannon Bard VS James-Lange

A

Cannon Bard thought that first we have a CENTRAL response and then peripheral (we show it to others)
James-Lange however thought the opposite

Q

Maclean proposed the…

A

TRIUNE ARCHITECTURE
1. BASAL GANGLIA (BRAINSTEM): ANCIENT REPTILIAN BRAIN, fear and aggression
2. LYMBIC SYSTEM: ‘OLD’ MAMMALIAN BRAIN
3. NEO (FRONTAL) CORTEX: ‘NEW’ MAMMALIAN BRAIN (interfaces emotion with cognition)

Q

Hipppcampus is also related to the limbic system (T/F)

A

Yes, we can link it to the memory.
We can learn how to deal with an exam when being anxious.
The hippocampus helps you to remind that sensation.

Q

PAPEZ proposed…

A

The hypothalamus-limbic lobe

17
Q

McLEAN proposed the…

A

Limbic-lobe connected to forebrain.
He said that the hippocampus helped us remember emotions

18
Q

LIMBIC SYSTEM
Role of amygdala

A

Is the emotion POSITIVE or NEGATIVE?

19
Q

We identify other people’s emotions thanks to…

A

The amygdala

20
Q

Where would you localise a lesion in a patient with facial emotion recognition deficits (as fear) and preserved skills in facial recognition?

A

In the amygdala (the person can distinguish the person but not their emotions)

21
Q

Amygdala is connected to…

A

Motor, prefrontal and visual cortex. And then it is sending info towards the brainstem.
If this circuit is damaged=bad emotional response

22
Q

Amygdala and accumbens

A

Fear= amygdala working
Joy/pleasure= nucleus accumbens

23
Q

If a lesion in …: placidity, hyperporality…

A

AMYGDALA

24
Q

Neurotransmitter nucleus accumbens in gratification response

A

Dopamine

25
Q

Nt amygdala in aversion response

A

Glutamate

26
Q

Emotional experience reflect an interpaly between … (Hypothalamus & Amygdala)

A

higher brain centers and subcortical regions

27
Q

Noxious or pleasurable stimuli trigger … ( simple to execute, requiring NO conscious control)

A

autonomic and endocrine responses

28
Q

Second set of mechanisms act later; involving …

A

cerebral cortex (feeling)

29
Q

Primary emotional responses are learned. Amygdala connect with … cortices ( cognitive interpretation of emotional states)

A

temporal & frontal

30
Q

Memory may activate ascending … projections to brainstem–activating the conscious sensation of the remembered emotional state (gut feelings)

A

NA & Ach
