Demonstration of eye‐position‐related and visual‐related responses recorded from same inferior parietal lobule neuron. A: animal fixates small light located 20° down from straight ahead in otherwise total darkness. Fixationpoint line indicates times when light was on and off. Lines H and V show horizontal and vertical eye‐position traces in degrees of visual angle (animal has been trained to maintain steady fixation even with fixation light off). B: same as A, but animal fixates target 20° down and 20° right. Tonic rate of activity in B is markedly reduced from that in A even when fixation light is off, indicating that cell is signaling eye position. C: animal fixates target, which does not blink off; a second test stimulus is flashed in visual field evoking visual‐related response. Ordinate, 4 spikes/division; abscissa, 1 s/division.

Figure 12. Figure 12.

Task for demonstrating eye‐position‐related activity. A and B: animal fixates (with head fixed) point of light in center of screen through two 25‐diopter prisms. A: prisms are base down so animal must look 14° up from straight ahead to fixate target. B: prisms are base up so animal must look down 14°. C and D: prisms are removed and animal is made to look 14° up (C) or 14° down (D) by moving fixation point up or down on screen. Angles of gaze are identical for A and C and for B and D; retinotopic positions of visual background are identical in A and B but different in C and D. Recording data indicate that cell activity varies with eye position but not with changes in retinotopic location of visual background. Lines H and V, horizontal and vertical eye positions measured in degrees of visual angle. Ordinate, 5 spikes/division; abscissa, 1 s/division.

Example of smooth‐pursuit‐related activity. Left, animal tracks point of light moving left to right 9°/s. Right, animal tracks in opposite direction. Histograms at top of figure are made from spike rasters immediately below; below rasters are eye‐position recordings; below eye‐position recordings are graphs showing position of fixation point with respect to time. KD, time at which animal pulls back behavior key and target begins to move; LM, time at which target light dims, signaling animal to push key forward; D, mean reaction time.

Figure 14. Figure 14.

Demonstration of pursuit‐related activity for medial superior temporal (MST) area neurons but not for middle temporal (MT) area neurons. A and C: animal tracks spot of light; line above histogram indicates position of tracking target vs. time. B and D: dashed lines of target‐position record indicate times at which tracking target was stabilized on retina and animal maintained smooth pursuit. Decreased activity of MT neuron during stabilization indicates that its activity was mainly due to visual stimulation resulting from movement of target image on retina. Maintained activity of MST neuron during stabilization indicates that cell has pursuit‐related activity not due to visual motion stimulation.

Directional selectivity of area 7a neuron. Upper left: spike raster, histogram, and eyeposition recordings illustrate response to visual stimulus moving 60°/s along horizontal meridian (contralateral to ipsilateral). Lower left: no response when same stimulus is moved in opposite direction. Right: spike rasters show almost no response to same stimulus if stationary and flashed at different locations along horizontal meridian.

Figure 18. Figure 18.

Two area 7a neurons with opposed directional sensitivity. Histograms depict activity evoked by stimuli sweeping along horizontal and vertical meridians. They were cut in half (at fixation point) and arranged so that upper panels show activity when motion was directed toward fixation point and lower panels show activity when stimuli had passed through and were moving away from fixation point. In both examples, cells respond only to inward motion.

Simple model for opposed directionality. Dark arrows, directional sensitivity for long sweeps of visual stimulus; dashed arrows, local directionality (strongest in direction of radial organization). Although some cells show this local directional organization, for many cells, opponent‐vector organization for long sweeps results from long‐range inhibitory interactions between receptivefield regions. +, Fixation point.

Example of inferior parietal lobule neuron sensitive to rotation of visual stimuli. A and B: initially vertical (A) or initially horizontal (B) bar projected onto screen facing test animal produced response when rotated clockwise but not counterclockwise. C: square also produced response only when rotated clockwise. D: same bar stimulus as in A and B did not evoke response when translated horizontally toward right or left. E: paired points rotating about fixation point (FP) activated neuron; F and G: neither point traveling alone in same trajectory produced response.

Example of inferior parietal lobule neuron sensitive to size change. A: cell responds somewhat to horizontal translation of visual stimulus in frontoparallel plane, preferring leftward motion. B: cell responds much more to stimuli moving in depth toward animal. C: expanding size of stimulus also activates neuron; size‐change sensitivity at least in part accounts for movement‐in‐depth sensitivity of cell.
