How long does attention modulation take to occur from stimulus onset? ~150 ms (200 ms for V4?)
What are some targets of attentional modulation of vision mentioned in the lecture? Superior temporal gyrus (early audition), hMT+/V5 (motion), V1-V4, and Fusiform gyrus (faces/houses).
What are some sources of attentional control mentioned in the lecture? Frontal eye field, superior parietal lobule (SPL) and precuneus, and intraparietal sulcus (IPS).
What did Motter's 1994 experiment show? When switching attention into the receptive field, the response increases, when switching attention out of the receptive field, it decreases. It takes about 200 milliseconds for the attention effect in V4.
What did Reynolds, Chelazzi, and Desimone 1999 show? When attention is away, two stimuli in the same receptive field of a V4 neuron tends to evoke a response that is intermediate of the responses of the individual stimuli. When attention is on one of the two stimuli in the same receptive field, the response goes more towards the response of the stimuli with the attention.
What did Moore, Armstrong (2003) show? They stimulated the FEF below the threshold needed to make a saccade. Stimulation had no effect when the receptive field was empty, but increased the response when a preferred stimulus was in the receptive field.
What did Bisley, Goldberg (2003) show? They recorded LIP neurons when targets or distractors (used to indicate where the probe was going to appear) appeared in their receptive fields. They showed that the response did not indicate whether the monkey was going to make a sacade to that location (response to target and distractor was similar).
What group performed an experiment where they switched attention into and away from receptive fields? Motter (1994).
What group stimulated the FEF below the threshold needed for saccades? Moore and Armstrong (2003)
What group studied the effect of attention selectively on one of two stimuli within the same receptive field? Reynolds, Chelazzi, and Desimone (1999)

What are two locations involved in attention / shifting attention? || Pulvinar nucleus and superior colliculus (also called optic tectum). | What did O'Craven et al (1997) show? || Something about domains of selection. |-
