Answer 1

Agency is loss of internal control

and more mental

Question 2

Somatophrenia

Answer 2

denial of ones limb or body part assoicated with RH and pareital dysfunction

Question 3

Moro

Answer 3

plegic hand, right-fronto-parietal lesion

single case study..

Question 4

Gondola review

Answer 4

patients with SP showed lesion pattern of sub-cortical regions, thalaus, basial gaglia, amygdala, more complex picture…

Question 5

But spence et al

Answer 5

looked at passivity symtpoms–> so thoughts and actions that arent your own, focused more on actions… and found those patients with schizophrenia had right parietal lobe anormalities.. consistent… potential biological mechanisms

Question 6

Alien hand syndrome

Answer 6

when you loose control of your hand, feeling of foreignness

Question 7

Marey and Lopez

Answer 7

patient with right infarct –> consitent with ideas about RH reduced sense of familaritty

Question 8

Cortical-basal degeneration

Answer 8

sometimes displays signs of alein hand syndrome, maybe something to do with basalganglia dysfunction??
got to remeber this is psychiatric phenomena, evidence showing that it seems to have a neurological basis.

Question 9

summary of agency according to physical loss of internal control..

Answer 9

disruption in agency by help from neurlogical findings seems to have an association with pariteal lobe and RH dysfunction

Question 10

Seek

Answer 10

EEG, implants of electrodes Temporoal lobe epilepsey–> psychosis
–> driving forces, left temporal lobe deficits

Question 11

Shenton

Answer 11

thought disorder in schizphrenia, left temporal lobe abnormalites … shows how psychiatric phemomena linked behaviour to brain dysfunction

Question 12

Hersh, 2012

Answer 12

SPECT pharmaco-resistant TLE, psychosis
thought she was being ruled by aliens
thought she was her dead uncle
–> left temporal lobe abnormalties

Question 13

The self

Answer 13

deficits in self processing

body perceptions, thoughts, physical self

Question 14

Autoscopy

Answer 14

Autoscopy is the experience in which an individual perceives the surrounding environment from a different perspective, from a position outside of his or her own body

Question 15

Blanke 2000

Answer 15

reduiplcation phenomena, TLE
had to find parts of the brain needed to save
operating as epilesey so bad
—> when activation of TPJ expereiences of autoscopy

Question 16

depersonalisation

Answer 16

a state in which one’s thoughts and feelings seem unreal or not to belong to oneself.

Question 17

Simeon et al, 2000

Answer 17

DP experienced metabolic abnormalities posteiror cortex and influence of TPJ –> link to autoposy physical self

Question 18

Adaptive mechnism–> detacchment from the self

Answer 18

found in patients with extreme life expeierinces

Question 19

blunted emotional response

Answer 19

Sierra and david –> fronto-limbic suppression mechnism, FL activation, and decrease in insular, limbic related areas

Question 20

Maybe DP is not to do with the physical self???

Answer 20

DP as a defcit to the vestibular system
caloric irrigation thought to evoke DP feelings
-found greater in vetibular disease group
-but frequency and quality of DP is significantly different
-Dp feeling thought to have arisen distorted vestibular signals mismatch with other sensory input that create this feeling

Question 21

Distortions in physical self–> Carey

Answer 21

Body dysmophic disorders, relative pareital + occipital diffusions, perfucsion defcits found in brain areas related to body processing, again see psychiatric phenomena.. but no control group

Question 22

Body dysmoprhic disorder–> fronto-temporal atrophy

Answer 22

Gabbay et al 2003

Question 23

the vestibular system

Answer 23

The Vestibular System, which is a contributor to our balance system and our sense of spatial orientation, is the sensory system that provides the dominant input about movement and equilibrioception. Vestibular sense provides information related to movement and head position
