TASK 5

Question 1

SYMPATHETIC DIVISON

Answer 1

activity in this region prepares to thretening situations

Question 2

parasympathetic deivision

Answer 2

promotes building of metabolic resources (food & drink)

Question 3

endocrine system

Answer 3

responsible for secretion of hormones in bloostream

Question 4

autonomic & endocrine sytem are part of

Answer 4

the bodys hoemeostatic regulatory mechanis,ms

ivolved in sleep , sex , hunger

Question 5

autonomic system

Answer 5

parasympathetic + sympathetic

Question 6

mclean

Answer 6

hippocampus responsible for bodily responses + concious feeling s

buuuut damgae to hippocampus does not cazse problems with emotion or feelings

Question 7

hypothalamus controls

Answer 7

motivational staes leading to eating drinking, sex

fundamental for life

Question 8

nonlimbic arousal

Answer 8

ARAS in reticular formation of brain stem ; aroeusal same as wehn we encounter novel stimuli

Question 9

limbic arousal

Answer 9

thissystem includes hypothalamus, activates sympathetic n system

arousal is accompanied by strong motivational bejaviour plus strong positive or negative affect ( pleausre& displeasure-> not like nonlimbic

Question 10

….

Answer 10

Amygdala  thalamus  orbital & medial frontal lobes

Amygdala  BG which receives info from PFC
 Thus, amygdala influences selection & initiation of behaviours aimed at obtaining rewards & avoiding punishment
 May also account for subjective feelings of emotional states as they need cognitive self-awareness

Question 11

 Orbital & medial frontal lobes

Answer 11

 Associate info from sensory modalities & integrate those
 Influence content retrieved from memory & help shape mental response plans parallel to amygdala
 Lesion in VMPFC = antisocial symptoms while still actually knowing the “rules”

Question 12

forced pyramidal smile

Answer 12

motor cortex & brainstem voluntairy contractiomn ; motor cortex & barinstem via pyramidal trcat

Question 13

duchenne smile

Answer 13

motor areas in anterior cingulate gyrus,
from medial frorebrain & hypothalamsu

extrapyramidal through reticular fromation

Question 14

reticular formation then

Answer 14

projects to motor neuron pool, produces visceral & somatic motor resposnses that overrides reflex

Question 15

episodic memory circuit

Answer 15

papez

Question 16

spatial memmory

Answer 16

parahippocampal unit

Question 17

emotional subsytem

Answer 17

 Amygdala  stria terminalis  septal nuclei & pre-optic nucleus of H where it can control expression of emotions
 Extended amygdala: central, medial & bed nucleus of stria terminalis (BST, set of nuclei surrounding stria)
 Main output channel
 Nuclei responsible for emotional expression (endocrine, autonomic & somatomotor aspects)
 Give rise to many pathways to hypothalamic & brainstem
 Receives input from several sensory systems

Question 18

Limbic Cortex

Answer 18

 High-end side – involved with cortex & voluntary behaviour
 Edge of the cerebral cortical sheet
 Bottom to top: uncus (= parahippocampal gyrus)  ictus (= ventral cingulate gyrus)  caudal orbitofrontal cortex & rostral insula

Question 19

cortex

Answer 19

 Hippocampal-diencephalic circuit
 Connects memory subsystem via cingulum with the posterior cingulate cortex
 Posterior cingulate cortex is the first major medial hub of the default mode network
 Temporo-amygdala-orbitofrontal network
 Integration of visceral & emotional states with cognition & behaviour
 Connects amygdala via orbitoinsular cortex with anterior cingulate cortex (which is the second major hub)
