Progress towards expanding the model to the full three-dimensional color space (to include S cone signals) will also be described.</font></div><div><br></div><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><span style="font-size: large;">By attending this webinar you will learn:</span><br></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">- What a color channel or mechanism is</font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">- How cone signals are combined into postoreceptoral mechanisms</font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">- How many color mechanisms there are</font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><span style="font-size: large; font-family: Arial, Helvetica, sans-serif; color: rgb(34, 34, 34);"><br></span></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><span style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: large;">If you are interested, please register to it even if you are unable to attend the live webinar since this webinar will be recorded and Optica will email all registrants when the webinar recording is available.</span><span style="font-size: large; font-family: Arial, Helvetica, sans-serif; color: rgb(34, 34, 34);"><br></span></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><span style="font-size: large; font-family: Arial, Helvetica, sans-serif; color: rgb(34, 34, 34);">You can register at:</span><br></p><div><a href="https://osa.zoom.us/webinar/register/WN_OMNdZWgDR72MRgf9g-rVtA" target="_blank" style="font-family: Arial, sans-serif;"><font size="4">https://osa.zoom.us/webinar/<wbr>register/WN_OMNdZWgDR72MRgf9g-<wbr>rVtA</font></a><br></div><div><br></div><div><font size="4"><br></font></div><div><font size="4">Hope to see you there!</font></div><font color="#888888"><font color="#888888"><font color="#888888" size="4"><div><br></div><div>-Francisco Imai</div></font></font></font></div></div></div></body></html>
