Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The N170 ERP is thought to be the brain activity occurring after the presentation of what sort of stimulus?
A
Familiar
B
Unfamiliar
C
Faces
D
Names
Explanation: 

Detailed explanation-1: -Face Processing The N170 also shows sensitivity to stimulus inversion. The response produced for inverted human faces is of greater amplitude and longer latency compared to upright human faces. This effect is specific to human face stimuli and has not been observed for animal faces.

Detailed explanation-2: -The N170 wave is an event-related brain potential (ERP) measured using electroencephalography (EEG). The N170 is a negative waveform that peaks at approximately 170 msec after stimulus presentation. It is observed at occipitotemporal sites and with greater amplitude over the right hemisphere.

Detailed explanation-3: -The N170 sources are mainly located in the occipital temporal lobe regions on both sides of the brain (Figures 4A, B).

Detailed explanation-4: -The N170 is a negative component evoked in the occipital temporal lobe region between 150 and 210 ms after visual stimulation, with the amplitude reaching a maximum at about 170 ms after stimulation.
