Optogenetics is an invaluable technique in neuroscience to study brain circuits. However, conventional optogenetic systems for rodents use optical fibers tethered to steady-state lasers to deliver light to the brain, which increases animal’s anxiety and hinders natural behavior. Therefore, we developed a novel…

Simultaneous recording of extracellular electrophysiological and calcium imaging signals enables a more comprehensive understanding of neural activity. Thus, we aimed to incorporate extracellular recording to our calcium imaging devices. The electrophysio-imaging device consists of a 450 x 1660 µm CMOS chip and…

Neuromorphic electronics, inspired by the functions of neurons, have the potential to enable biomimetic communication with cells. Such systems require operation in aqueous environments, generation of sufficient levels of ionic currents for neurostimulation, and plasticity. However, their implementation requires a…

Neurostimulation employing photoactive organic semiconductors presents a promising alternative to conventional techniques, enabling targeted action and wireless control through light. This study investigates the efficacy of stimulation of the neuronal networks in vivo using organic electrolytic photocapacitors (OEPC)…

One of the advantages of infrared neuromodulation (INM) compared to the classical electrical stimulation is that INM does not induce photoelectric artefacts in electrophysiological recordings. Another advantageous property of INM is that the propagation of light can be shaped easier than in case of electrical signals.…

As the field of neuroscience has undergone significant advancements in understanding individual brain regions, research aimed at elucidating neural networks within multiple brain areas is increased. Techniques like fluorescence imaging, including GCaMP, stand out as formidable methodologies within brain function…

Optogenetics is a powerful tool that allows controlling cellular activity with light by optically activating either excitatory or inhibitory synaptic ion channels. In this project, we study the effect of simultaneous optogenetic activation and inhibition in the same cells of transgenic Drosophila larvae using…
