Maharbiz, Chair Professor Elad Alon Professor John Ngai Fall 2016 Neural Dust: Ultrasonic Biological Interface Copyright 2016 by Dongjin Seo 1 Abstract Neural Dust: Ultrasonic Biological Interface by Dongjin Seo Doctor of Philosophy in Engineering - Electrical Engineering and Computer Sciences University of California, Berkeley Professor Michel M. Maharbiz, Chair A seamless, high density, chronic interface to the nervous system is essential to enable clinically relevant applications such as electroceuticals or brain-machine interfaces (BMI). Currently, a major hurdle in neurotechnology is the lack of an implantable neural interface system that remains viable for a patient's lifetime due to the development of biological response near the implant. -

Neuroplasticity in Adult Human Visual Cortex
Neuroplasticity in adult human visual cortex Elisa Castaldi1, Claudia Lunghi2 and Maria Concetta Morrone3,4 1 Department of Neuroscience, Psychology, Pharmacology and Child health, University of Florence, Florence, Italy 2 Laboratoire des systèmes perceptifs, Département d’études cognitives, École normale supérieure, PSL University, CNRS, 75005 Paris, France 3 Department of Translational Research and New technologies in Medicine and Surgery, University of Pisa, Pisa, Italy 4 IRCCS Stella Maris, Calambrone (Pisa), Italy Abstract Between 1-5:100 people worldwide has never experienced normotypic vision due to a condition called amblyopia, and about 1:4000 suffer from inherited retinal dystrophies that progressively lead them to blindness. While a wide range of technologies and therapies are being developed to restore vision, a fundamental question still remains unanswered: would the adult visual brain retain a sufficient plastic potential to learn how to ‘see’ after a prolonged period of abnormal visual experience? In this review we summarize studies showing that the visual brain of sighted adults retains a type of developmental plasticity, called homeostatic plasticity, and this property has been recently exploited successfully for adult amblyopia recover. Next, we discuss how the brain circuits reorganizes when visual stimulation is partially restored by means of a ‘bionic eye’ in late blinds with Retinitis Pigmentosa. The primary visual cortex in these patients slowly became activated by the artificial visual stimulation, indicating that -

A New Curriculum in Neural Engineering with Emphasis on Design of Neural Systems
Session ???? A New Curriculum in Neural Engineering with Emphasis on Design of Neural Systems John R. Hetling, Christopher M. Comer*, and Richard L. Magin Departments of Bioengineering / *Biological Sciences, University of Illinois at Chicago Introduction. Academic and commercial research teams are currently developing a new generation of devices that will interact with, incorporate, and/or emulate living nervous systems. Neural prostheses to restore hearing, mobility or sight will offer a wider range of function; robotic devices will become more effective with “neuromorphic” control systems; fundamentally new methods for processing information will be motivated by biological systems. Neural Engineering is the intellectual force behind these developments, supported by recent advances in cellular neurobiology, microfabrication and neural modeling. Based on decades of quantitative approaches to increase our understanding of neural systems, bioengineers are now beginning to design neural systems and neural interfaces. Neural engineers have new tools to control aspects of these systems such as guided axon growth and multielectrode arrays for stimulation and recording. In addition to potential applications attracting the attention of biotech and defense industries, these efforts in turn increase our understanding of natural neural systems. One of the most intriguing aspects of contemporary Neural Engineering is the increasing degree to which scientists can repair and exploit the properties of neural systems, including applications such as neural prostheses, biosensors, or hybrid neural computing devices. The former application currently supports significant industrial involvement; for example, Clarion and Medtronic have commercially available cochlear implants, and Optobionics Inc. (IL) and Second Sight (CA) are companies developing prostheses for vision (in existence for approximately 14 and 4 years, respectively). -

Intention, Emotion, and Action: a Neural Theory Based on Semantic Pointers
Cognitive Science 38 (2014) 851–880 Copyright © 2013 Cognitive Science Society, Inc. All rights reserved. ISSN: 0364-0213 print / 1551-6709 online DOI: 10.1111/cogs.12100 Intention, Emotion, and Action: A Neural Theory Based on Semantic Pointers Tobias Schroder,€ Terrence C. Stewart, Paul Thagard Department of Philosophy, University of Waterloo Received 14 May 2012; received in revised form 3 March 2013; accepted 28 March 2013 Abstract We propose a unified theory of intentions as neural processes that integrate representations of states of affairs, actions, and emotional evaluation. We show how this theory provides answers to philosophical questions about the concept of intention, psychological questions about human behav- ior, computational questions about the relations between belief and action, and neuroscientific questions about how the brain produces actions. Our theory of intention ties together biologically plausible mechanisms for belief, planning, and motor control. The computational feasibility of these mechanisms is shown by a model that simulates psychologically important cases of intention. Keywords: Intention; Emotion; Action; Implementation intentions; Automatic; Deliberative; Planning; Neural engineering framework; Semantic pointers 1. The problem of explaining intention The concept of intention is important in many disciplines, including philosophy, psy- chology, artificial intelligence, cognitive neuroscience, and law. For example, criminal law treats cases where one person intends to kill another very differently from cases where death results unintentionally from negligence. Despite decades of discussions, how- ever, there is no received theory of intention within any of these disciplines, let alone a theory that accounts for all the phenomena identified across all of the disciplines. We propose a unified theory of intentions as neural processes that integrate representa- tions of states of affairs, actions, and emotional evaluation. -
