Dr. Rao is a researcher in the fields of computational neuroscience, artificial intelligence, and brain-computer interfacing. With Dana Ballard, he proposed the predictive coding model of brain function in 1999. [2] He has contributed to Bayesian models of perception and decision making. In brain-computer interfacing, Prof. Rao and his collaborators were the first to demonstrate direct brain control of a humanoid robot in 2007. [3] [4]

In the first demonstration of human brain-to-brain communication in August 2013, Rao wearing an electrical brain-signal reading cap triggered the movement of his colleague Andrea Stocco's hand via the Internet, allowing their brains to cooperate to solve a computer game. [5] The demonstration was subsequently replicated across other pairs of humans, [6] and extended to other tasks, [7] and to a BrainNet for more than two brains. [8]

Rao also works on the decipherment of the Indus script. [9] By comparing the entropy of the Indus script with entropies of linguistic scripts such as those for Sumerian and Old Tamil, and nonlinguistic sequences such as DNA and a programming language, his work suggested that the Indus script behaves more like a linguistic script than nonlinguistic sequences. [10] [11] He has also given a TED talk on this topic where he backed the Dravidian hypothesis put forward by Iravatham Mahadevan. [12]

Rao is the author of the book Brain-Computer Interfacing (Cambridge University Press, 2013) and co-editor of two volumes, Probabilistic Models of the Brain (MIT Press, 2002) and Bayesian Brain (MIT Press, 2007). He has given a TEDx talk on "Brain co-processors: When AI meets the Brain." [13]

With Prof. Adrienne Fairhall, Rao offered the first massive open online course in computational neuroscience in 2013. The course continues to be offered on Coursera. [14]

Rao graduated summa cum laude from Angelo State University in 1992 with a B.S. degree in Computer Science/Mathematics. He then attended the University of Rochester where he earned his Master's degree (1994) and Ph.D. (1998) in Computer Science. [1] He was a Sloan Postdoctoral Fellow at the Salk Institute for Biological Studies before joining the University of Washington faculty in 2000.

Computational biology refers to the use of data analysis, mathematical modeling and computational simulations to understand biological systems and relationships. An intersection of computer science, biology, and big data, the field also has foundations in applied mathematics, chemistry, and genetics. It differs from biological computing, a subfield of computer science and engineering which uses bioengineering to build computers.

<span class="mw-page-title-main">Mind uploading</span> Hypothetical process of digitally emulating a brain

Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate the mental state of the individual in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and experience having a sentient conscious mind.

Neuromorphic computing is an approach to computing that is inspired by the structure and function of the human brain. A neuromorphic computer/chip is any device that uses physical artificial neurons to do computations. In recent times, the term neuromorphic has been used to describe analog, digital, mixed-mode analog/digital VLSI, and software systems that implement models of neural systems. The implementation of neuromorphic computing on the hardware level can be realized by oxide-based memristors, spintronic memories, threshold switches, transistors, among others. Training software-based neuromorphic systems of spiking neural networks can be achieved using error backpropagation, e.g., using Python based frameworks such as snnTorch, or using canonical learning rules from the biological learning literature, e.g., using BindsNet.

<span class="mw-page-title-main">Brain–computer interface</span> Direct communication pathway between an enhanced or wired brain and an external device

A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI) or smartbrain, is a direct communication pathway between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary component of the physical movement of body parts, although they also raise the possibility of the erasure of the discreteness of brain and machine. Implementations of BCIs range from non-invasive and partially invasive to invasive, based on how close electrodes get to brain tissue.

<span class="mw-page-title-main">Indus script</span> Symbols of the Indus Valley Civilisation

The Indus script, also known as the Harappan script, is a corpus of symbols produced by the Indus Valley Civilisation. Most inscriptions containing these symbols are extremely short, making it difficult to judge whether or not they constituted a writing system used to record the as-yet unidentified language(s) of the Indus Valley Civilisation. Despite many attempts, the 'script' has not yet been deciphered, but efforts are ongoing. There is no known bilingual inscription to help decipher the script, which shows no significant changes over time. However, some of the syntax varies depending upon location.

Academics find his scholarship to be composed of dishonest polemics in service of a communal agenda.

<span class="mw-page-title-main">Wetware computer</span> Computer composed of organic material

A wetware computer is an organic computer composed of organic material "wetware" such as "living" neurons. Wetware computers composed of neurons are different than conventional computers because they use biological materials, and offer the possibility of substantially more energy-efficient computing. While a wetware computer is still largely conceptual, there has been limited success with construction and prototyping, which has acted as a proof of the concept's realistic application to computing in the future. The most notable prototypes have stemmed from the research completed by biological engineer William Ditto during his time at the Georgia Institute of Technology. His work constructing a simple neurocomputer capable of basic addition from leech neurons in 1999 was a significant discovery for the concept. This research acted as a primary example driving interest in the creation of these artificially constructed, but still organic brains.

Neuroinformatics is the field that combines informatics and neuroscience. Neuroinformatics is related with neuroscience data and information processing by artificial neural networks. There are three main directions where neuroinformatics has to be applied:

Neurorobotics is the combined study of neuroscience, robotics, and artificial intelligence. It is the science and technology of embodied autonomous neural systems. Neural systems include brain-inspired algorithms, computational models of biological neural networks and actual biological systems. Such neural systems can be embodied in machines with mechanic or any other forms of physical actuation. This includes robots, prosthetic or wearable systems but also, at smaller scale, micro-machines and, at the larger scales, furniture and infrastructures.

The Roja Muthiah Research Library (RMRL), in Chennai, India, was founded in 1994, and opened to researchers in 1996; it provides research materials for Tamil studies in a variety of fields of the humanities, social sciences, and sciences. The Library is based on the collection of Roja Muthiah, who accumulated one of the world's finest private libraries of Tamil publications.

Dana Harry Ballard (1946–2022) was a professor of computer science at the University of Texas at Austin and formerly with the University of Rochester.

The concept of biological computation proposes that living organisms perform computations, and that as such, abstract ideas of information and computation may be key to understanding biology. As a field, biological computation can include the study of the systems biology computations performed by biota the design of algorithms inspired by the computational methods of biota, the design and engineering of manufactured computational devices using synthetic biology components and computer methods for the analysis of biological data, elsewhere called computational biology or bioinformatics.

A brain–brain interface is a direct communication pathway between the brain of one animal and the brain of another animal.

In neuroscience, predictive coding is a theory of brain function which postulates that the brain is constantly generating and updating a "mental model" of the environment. According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. With the rising popularity of representation learning, the theory is being actively pursued and applied in machine learning and related fields.
