Figure 2: (A) In-vivo imaging of neurons with two-photon microscopy. The image shows the xz plane reconstruction of calcium-sensor-expressing cortical neurons in posterior parietal cortex . The dotted line indicates the imaging plane in (B). Neurons coding sound-source distance were extracted by LASSO. 282 neurons colored red or blue were found among 540 neurons (B). The color depth shows the weights in LASSO. (C) Distance estimation extracted from neuronal activity with LASSO. Horizontal and vertical axes show the actual and estimated distance to sound source, respectively. The estimations were successful even during the no-sound periods in the intermittent condition.
