0 a multiunit building contains lots of different apartments or stores:
A hand-held, 1-cm square black flag was used to explore the multiunit visual responses and determine the center of their receptive fields.
The size and location of single and multiunit receptive fields were plotted in azimuth and elevation relative to the area centralis.
What about joint selectivities established from multiunit recordings?
The retinotopic organization of gamma activity is as precise as that of visually evoked potentials and follows that derived from multiunit mapping.
Likewise, the peripheral receptive field was evaluated with a separate stimulus and each parameter was fixed to drive the multiunit activity maximally.
The size of multiunit receptive fields does not change with eccentricity and cortical magnification factors decrease only slightly with increasing eccentricity.
This intermediate level of recordings should help to bridge the gap between multiunit and scalp recordings.
For each recording site, the optimum orientation and ocular preference of the multiunit activity, including the indiscriminate "hash" displayed on the audio monitor, were determined.
