Development of extracellular electrophysiology methods for scalable neural recording
… to test computational models of neural circuits. Extracellular electrophysiology is a neural recording method that has been developed to record from large populations of neurons, but well-known problems with signal attribution pose an existential threat to the viability of further system scaling, …

Devices for Extracellular Detection of Astrocytic Infraslow Electrophysiological Biomarkers
… To investigate the nature of astrocytes’ extracellular electrophysiology and validate the hypothesis that they contribute to the generation of DC shifts, it is crucial to develop tools capable of detecting low-amplitude infraslow electrical signals. Conventional electrodes are invaluable …

Causal evidence for the behavioral impact of oscillations in neocortex and hippocampus
… measures. Finally, I present a new platform for extracellular electrophysiology. This platform, called Open Ephys, makes the closed-loop experiments that are ideal for studying oscillations accessible to a wider audience.

Optical measurement of neural action potentials using low coherence heterodyne interferometry
… be identified with the electric signal from the extracellular electrophysiology. A dual-beam probe was designed and built based on this interferometer. The probe is a fiber optic unit with an integrated referencing surface. The probe simplified the data taking process as well as improved the …

Investigating the role of thalamic activity in visual cortical plasticity
… Chapter 3, I summarize an experiment which used extracellular electrophysiology to compare the differences in dLGN spiking activity to familiar vs. novel stimuli. In short, no differences in the activity of dLGN cells were found to familiar vs. novel stimuli using either method, a novel finding …

Evidence for effects of phoenixin on neurons of the paraventricular nucleus
… of PNX on PVN neuronal activity using in vitro extracellular recordings. Recordings from a total of 824 neurons showed that 16% (n= 130) of these cells were activated by bath administration of PNX, while 14% (n= 117) were inhibited. Remaining cells tested showed no obvious changes in spike …

Finding Common Ground: The Common Marmoset as a Model to Accessing and Providing Insight into the Social Brain
… within face patches has been explored through extracellular electrophysiology, the functional architecture of local ensembles of cells has remained elusive. Recently discovered face patches in the lissencephalic common marmoset brain provide the cortical access necessary in order to employ …

Intrinsic Optical Imaging of Cortex During Deep Brain Stimulation: Parameters, Spatiotemporal Dynamics and Neurovascular Coupling
… thought to be imperative in this therapy. Recent electrophysiology and imaging studies investigating the effects of DBS on motor cortex have reported contradictory results. One reason of this disagreement is that functional imaging techniques (functional magnetic resonance imaging and positron …
