Response inhibition

Question 1

Tasks

Answer 1

Go No-go task (nogo should be rarer)

Stop signal reaction task (Go RT - stop signal delay = inhibitory strength)

Question 2

Inhibition network

Answer 2

Most in the right Inferior Frontal Gyrus (IFG)

Ability to rapidly abort a planned/ongoing action

Question 3

SSRT distribution

Answer 3

You can calculate the SSRT:

• SSD (time between primary stimulus and stop sign) is varied to yield 50% P inhibition (Median no-signal RT)

SSRT = that median GoRT - the average SSD

Question 4

Damage to right IFG

Answer 4

Directly correlated to the experiment, the more damage, the longer the SSRT.
