MIGUEL A. L. NICOLELIS
In creating the field of neuroengineering, Miguel A.L. Nicolelis’ pioneering work on brain-machine interfaces has completely changed people’s perception of what brains can do and how such research can be rapidly applied to help humans. Nicolelis demonstrated that humans can use raw brain activity to directly communicate with mechanical, electronic, and virtual devices in real time and in a closed control loop. He played a key role in the development of a robotic exoskeleton that can help paralyzed individuals to walk. He focused on methods to read a paraplegic person’s brain waves and decode and use them to move hydraulic drivers on the suit. His work has great implications for patients with epilepsy, Parkinson’s disease, and spinal cord injury. An IEEE Member, Nicolelis is the Duke School of Medicine Distinguished Professor of Neuroscience at Duke University, Durham, NC, USA. TAGLINE: Leader in developing neuroprosthetic devices that harness brain activity is revolutionizing therapies for patients suffering from severe levels of paralysis.

Restoring Movement after Paralysis and the Future of Bioelectronic Medicine
Millions of people worldwide currently suffer from diseases and injuries leading to severe paralysis. Bioelectronic technology is now being developed to restore movement by decoding and re-routing neural signals around damaged or degenerated neural pathways. It has previously been shown that signals recorded in the brain can be decoded and linked to assistive technology and robotic devices. In non-human primates, these signals have also been used to activate chemically paralyzed arm muscles. More recently, it has been shown signals recorded within the brain can be linked in real-time to muscle activation to restore movement in a paralyzed human. Functional movement and rhythmic movement have now both been demonstrated, with the potential to have a positive impact on the quality of life for paralyzed patients. Bioelectronic medicine research has opened many new doors to ways for treating not only spinal cord injury, but potentially stroke and brain injury as well, leading to many potential treatment options for patients worldwide in the future.

Brain circuits involved in phantom limb pain: Implications for treatment
Phantom limb pain is a frequent sequel of an amputation occurring in up to 80% of the amputee population. Peripheral factors such as local changes at the residual limb, alterations in severed nerves and associated dorsal root ganglia, as well as central changes such as spinal and supraspinal plastic changes including structural and functional changes have been examined. Moreover, input from the amputated limb has been discussed as a crucial factor. New insights about central changes have also come from studies on somatosensory illusions and altered body perception. These hypotheses have led to new behavioral and pharmacological treatment option that target maladaptive plasticity and learning and sensory incongruence phenomena. The treatments include prosthesis use, discrimination training, mirror treatment, video feedback, imagery, virtual reality applications, brain-computer interfaces as well as combinations of these treatments with pharmacological interventions. We will provide a critical overview of these recent developments on sources and treatments of phantom limb pain and discuss the need for causal experimental designs.

Neurophysiology of Cognitive Control in Human Prefrontal Cortex
In our day-to-day lives, we are constantly faced with decisions. For example, when approaching an intersection in which the traffic light turns yellow, we must make an optimal decision about whether to hit the brake or accelerator. Our brain’s decision-making circuitry must incorporate relevant information (speed, distance to the intersection, presence of police, etc.), ignore irrelevant information (children arguing in the back seat), factor in long-term goals (avoid a traffic violation), and modify future behavior based on previous outcomes. The neurocognitive processes that permit such controlled decision-making can be subsumed under the term “cognitive control,” which refers to the allocation of mental resources to optimize the performance of goal-driven behavior. The prefrontal cortex (PFC) is known to play an important role in cognitive control. We have studied these processes in the human brain using the opportunities afforded by neurosurgical procedures requiring intracranial neurophysiological recordings, such as deep brain stimulation or epilepsy surgery. In these procedures, we typically have to place electrodes in a variety of brain regions for clinical purposes. Consenting patients can then engage in behavioral tasks that allow us to study components of the decision-making process. Using this paradigm, we have recorded from two critical regions in the cognitive control network, the dorsal anterior cingulate cortex (dACC) and dorsolateral PFC (dlPFC). We find that individual dACC neurons encode specific aspects of stimulus parameters that are relevant for the decision. These neurons’ firing rate also encodes an estimate of the amount of cognitive effort required to perform the task. Analysis of population activity (local field potentials, LFP) reveals that this information is transmitted from dACC to dlPFC using a “carrier signal” in the form of oscillatory activity in the theta (4-7 Hz) range. dACC neurons conveying relevant information synchronize their firing to theta oscillations, which carry the information over the relatively large expanse to dlPFC. A large fraction of dlPFC neurons, in turn, synchronize their firing to the theta signal. This spike-LFP coherence is a likely mechanism for coordinating information transfer between individual neurons and larger neural populations across brain regions. Precise temporal coordination of these signals between these structures allows the decision-making circuitry to optimize the selection and timing of our responses, enabling us to seamlessly execute well-controlled behaviors.
