Document Summary

Movement inhibition: inhibitory laboratory tasks types of inhibitions. We want to respond as fast as we can. Either a go or a no-go signal. We know the response in advance but identifying the stimulus is different. The startle is not prepared in advance. Whe(cid:374) it"s a go, (cid:455)ou release the (cid:271)reaks (cid:271)ut (cid:449)he(cid:374) it"s a (cid:374)o-go you keep the breaks. Two cortical areas involved in inhibition: basal ganglia and reticular formation. If this cortical area is responsible for applying these breaks and we use theta burst stimulations (ctbs) (it decreases activity of neurons) to the neurons, essentially what (cid:449)e"re doi(cid:374)g is re(cid:373)o(cid:448)i(cid:374)g the (cid:271)reaks. Positive e value increased the value of wrong responses. Negative value is improved and they respinded less ofrten. This stimulation impaired their ability to stop (rifg and presma) Even though the area (cid:449)as shut do(cid:449)(cid:374), it did(cid:374)"t (cid:272)ause the(cid:373) to prepare this (cid:373)o(cid:448)e(cid:373)e(cid:374)t. As soon as stimulus is presented, you then start to prepare the response.
