We describe a low-cost, small, remotely triggerable LED device for wireless control of transcranial optical stimulation of cortical neurons, for use in freely moving mice. The device is easily mountable on the head of a mouse with a high-polymer block. Using the Thy1-ChR2-YFP transgenic mice, we demonstrate that the device is capable of remotely triggering muscle twitches upon activation of the...

Since the launch of Landsat-1 28 years ago, remotely sensed data have been used to map features on the earth's surface. An increasing number of health studies have used remotely sensed data for monitoring, surveillance, or risk mapping, particularly of vector-borne diseases. Nearly all studies used data from Landsat, the French Système Pour l'Observation de la Terre, and the National Oceanic an...
