Dr. Choa introduces neural circuit exploration and goes on to discuss neural circuit intervention with an emphasis on noninvasive neural modulations.

In modern computing systems and communication networks, are usually separate data channels and control channels.  Control channels are either in-band or out of band, effectively control and route large data flows in data channels. The exploration of equivalent control functions or control networks in human central and peripheral nerve systems (CNS and PNS) may lead to better understanding of neural circuitry. Recently proposed Electroencephalography (EEG) brainwave signals have been sources of brain attention control to synchronize and desynchronize oscillations in different brain areas. Dr. Choa offers techniques to scan and identify preferred EEG control channels in each person’s brain and their influence on the person’s attention control. In addition, he shows an example using EEG coherence calculation to study multi-language and bistable perception.

The ability to apply the use of neural modulation techniques to both CNS and PNS accuracy as a better understanding of neural anatomy of their detailed functions realized.  This provides the opportunity for electrical signal enhancement potentially treating neural diseases, recalibrate sensory systems, and improve health down to cell and even molecular levels. Dr. Choa will present some interesting representative examples and point to future direction of technology development.

For the last ten years, Dr. Choa has successfully continued to work on tunable quantum cascade lasers and photo-acoustic chemical sensing. He is a co- Principal Investigator (PI) of the National Science Foundation (NSF) Mid-Infrared Technologies for Health and the Environment (MIRTHE) Engineering Research Center., As a co-PI, Dr. Choa key responsibilities include the scientific and technical direction of the project. In addition, he currently is researching EEG signal recording and analysis of brain control circuits, with an attention, on transcranial magnetic stimulation (TMS) for treatment of pain, addiction, and neural degenerate diseases.  Choa’s lab undergraduate projects include EEG signal extraction for robot arm control, neuron optical and ultrasonic excitation, and energy generations. Dr. Choa is a contributing local EMBS member, a Fellow of the International Society for Optical Engineering (SPIE) advancing an interdisciplinary approach to the science and application of light as well as the Optical Society of America (OSA).
