Question

(3) when you turn on the neurons in primary visual cortex (v1), what will the human participant see?
dots moving around
human faces
interposition
lines / edges oriented at specific angl
pokemon

Explanation:

Primary visual cortex (V1) neurons are known to be orientation - selective. They respond best to lines/edges oriented at specific angles. Dots moving around are more related to motion - sensitive areas (like MT/V5 in some cases). Human faces are processed in higher - order visual areas like the fusiform face area. Interposition is a depth cue related to more complex visual scene analysis beyond V1. Pokémon (or any complex, learned object) is processed in higher - level visual and associative areas.

Answer:

lines / edges oriented at specific angl
