Biological: Fronto-Parietal Temporal Circuits (Mirror Circuits)

Question 1

What/Where is the Mirror Neuron System?

Answer 1

Cluster of neurons in the frontal parietal system.

Question 2

MNS originally discovered in monkeys, fire when:
The monkey performs an action
The monkey observes another individual performing a similar action

Answer 2

De Pellegrino et al (1992)

Rizzollati et al (1996)

Question 3

fMRI provides evidence that MNS is active during action observation, execution, and imitation

Answer 3

Acaboni et al (2005)

Question 4

MONKEYS

Answer 4

Question 6

DCD

Reynolds (2015)

Answer 6

Functional MRI 14 DCD boys and 12 controls
Observing, executing and imitating a sequencing task with right hand.
DCD=Decreased cortical activation in MN related brain regions.

Question 7

Functional MRI 14 DCD boys and 12 controls
Observing, executing and imitating a sequencing task with right hand.
DCD=Decreased cortical activation in MN related brain regions.

Answer 7

LIMITATION: Lingnau (2009)

Answer 8

Significant asymmetry between motor acts observed>executed and executed>observed
MN do not exist in humans.

Question 9

Significant asymmetry between motor acts observed>executed and executed>observed
MN do not exist in humans.
