| 15:00 - 16:00 Seminar The code for facial identity in the primate brain School COGNITIVE SCIENCES Abstract: One central question about the visual system is how objects are represented in high-level visual neurons. We investigated this question on a special class of objects--faces. Combining fMRI and electrophysiology, neurons in macaque face patches were targeted for recording while presenting thousands of facial images generated by an algorithm developed in the field of computer vision. We found that each face cell's firing rate is proportional to the projection of an incoming face stimulus onto a single axis in this space. Using this code, we could decode faces from neural population responses and predict neural firing rates to f ... |
