Microstimulation of V1 delays visually guided saccades: a parametric evaluation of delay fields
Abstract Electrical microstimulation of macaque striate cortex (area V1) delays the execution of saccadic eye movements made to a visual target placed in the receptive field of the stimulated neurons. The region of visual space within which saccades are delayed is called a delay field. We examined t...

| 520 | |a Abstract Electrical microstimulation of macaque striate cortex (area V1) delays the execution of saccadic eye movements made to a visual target placed in the receptive field of the stimulated neurons. The region of visual space within which saccades are delayed is called a delay field. We examined the effects of changing the parameters of stimulation and target size on the size of a delay field. Rhesus monkeys were required to generate a saccadic eye movement to a punctate and white visual target presented within or outside the receptive field of the neurons under study. On 50% of trials, a train of stimulation consisting of 0.2-ms anode-first pulses was delivered to the neurons before the onset of the visual target. Stimulations were performed in the operculum at 0.9–2.0 mm below the cortical surface. It was found that increases in current (50–100 μA), pulse frequency (100–300 Hz), or train duration (75–300 ms) increased the size of a delay field and increases in target size (0.1°–0.2° of visual angle) decreased the size of a delay field. Delay fields varied in size between 0.1 and 0.6° of visual angle. These results are related to the properties of phosphenes induced by electrical stimulation of V1 in humans and compared to the interference effects observed following transcranial magnetic stimulation of human V1. | ||

The region of visual space within which saccades are delayed is called a delay field. We examined the effects of changing the parameters of stimulation and target size on the size of a delay field. Rhesus monkeys were required to generate a saccadic eye movement to a punctate and white visual target presented within or outside the receptive field of the neurons under study. On 50% of trials, a train of stimulation consisting of 0.2-ms anode-first pulses was delivered to the neurons before the onset of the visual target. Stimulations were performed in the operculum at 0.9–2.0 mm below the cortical surface. It was found that increases in current (50–100 μA), pulse frequency (100–300 Hz), or train duration (75–300 ms) increased the size of a delay field and increases in target size (0.1°–0.2° of visual angle) decreased the size of a delay field. Delay fields varied in size between 0.1 and 0.6° of visual angle.

The region of visual space within which saccades are delayed is called a delay field. We examined the effects of changing the parameters of stimulation and target size on the size of a delay field. Rhesus monkeys were required to generate a saccadic eye movement to a punctate and white visual target presented within or outside the receptive field of the neurons under study. On 50% of trials, a train of stimulation consisting of 0.2-ms anode-first pulses was delivered to the neurons before the onset of the visual target. Stimulations were performed in the operculum at 0.9–2.0 mm below the cortical surface. It was found that increases in current (50–100 μA), pulse frequency (100–300 Hz), or train duration (75–300 ms) increased the size of a delay field and increases in target size (0.1°–0.2° of visual angle) decreased the size of a delay field. Delay fields varied in size between 0.1 and 0.6° of visual angle. These results are related to the properties of phosphenes induced by electrical stimulation of V1 in humans and compared to the interference effects observed following transcranial magnetic stimulation of human V1.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Occipital cortex</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electrical stimulation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Phosphenes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Transcranial magnetic stimulation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Rhesus monkeys</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Slocum, Warren M.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Experimental brain research</subfield><subfield code="d">Berlin : Springer, 1966</subfield><subfield code="g">176(2006), 3 vom: 01.

Microstimulation of V1 delays visually guided saccades: a parametric evaluation of delay fields |
| abstract |
Abstract Electrical microstimulation of macaque striate cortex (area V1) delays the execution of saccadic eye movements made to a visual target placed in the receptive field of the stimulated neurons. The region of visual space within which saccades are delayed is called a delay field. We examined the effects of changing the parameters of stimulation and target size on the size of a delay field. Rhesus monkeys were required to generate a saccadic eye movement to a punctate and white visual target presented within or outside the receptive field of the neurons under study. On 50% of trials, a train of stimulation consisting of 0.2-ms anode-first pulses was delivered to the neurons before the onset of the visual target. Stimulations were performed in the operculum at 0.9–2.0 mm below the cortical surface. It was found that increases in current (50–100 μA), pulse frequency (100–300 Hz), or train duration (75–300 ms) increased the size of a delay field and increases in target size (0.1°–0.2° of visual angle) decreased the size of a delay field. Delay fields varied in size between 0.1 and 0.6° of visual angle. These results are related to the properties of phosphenes induced by electrical stimulation of V1 in humans and compared to the interference effects observed following transcranial magnetic stimulation of human V1. © Springer-Verlag 2006 |
