Simultaneous transcranial magnetic stimulation and single-neuron recording in alert non-human primates.
Abstract
Transcranial magnetic stimulation (TMS) is a widely used, noninvasive method for stimulating
nervous tissue, yet its mechanisms of effect are poorly understood. Here we report
new methods for studying the influence of TMS on single neurons in the brain of alert
non-human primates. We designed a TMS coil that focuses its effect near the tip of
a recording electrode and recording electronics that enable direct acquisition of
neuronal signals at the site of peak stimulus strength minimally perturbed by stimulation
artifact in awake monkeys (Macaca mulatta). We recorded action potentials within ∼1
ms after 0.4-ms TMS pulses and observed changes in activity that differed significantly
for active stimulation as compared with sham stimulation. This methodology is compatible
with standard equipment in primate laboratories, allowing easy implementation. Application
of these tools will facilitate the refinement of next generation TMS devices, experiments
and treatment protocols.

My goal is to understand how humans produce purposeful, adaptive behavior. The main
ingredient for adaptive behavior, in all animals, is memory: we understand the world
around us by matching the flow of incoming sensory information to previous experience.
Importantly, by retrieving past episodes that resemble our present situation, we can
predict what is likely to happen next, thus anticipating forthcoming stimuli and advantageous
responses learned from past outcomes. Hence, I am interested i

Our research employs engineering approaches to understand and control neural function.
We work on fundamental questions and applied development in electrical stimulation
of the nervous system to restore function to individuals with neurological impairment
or injury.
Current projects include:• understanding the mechanisms of and developing advanced
approaches to deep brain stimulation to treat movement disorders, • developing
novel approaches to peripheral nerve e

I direct the Brain Stimulation Engineering Lab (BSEL) which focuses on the development,
modeling, and application of devices and paradigms for transcranial brain stimulation.
Transcranial brain stimulation involves non-invasive delivery of fields (e.g., electric
and magnetic) to the brain that modulate neural activity. It is widely used as a tool
for research and a therapeutic intervention in neurology and psychiatry, including
several FDA-cleared indications. BSEL develops novel technology s

Our lab tries to understand how the brain makes decisions. We are particularly interested
in the biological mechanisms that allow people and other animals to make decisions
when the environment is ambiguous or complicated by the presence of other individuals.
We use a broad array of techniques, including single neuron recordings, microstimulation,
neuropharmacology, eye tracking, brain imaging, and genomics to answer these questions.
Our work is motivated by ethology, evolutionary biology, and e

We study circuits for cognition. Using a combination of neurophysiology and biomedical
engineering, we focus on the interaction between brain areas during visual perception,
decision-making, and motor planning. Specific projects include the role of frontal
cortex in metacognition, the role of cerebellar-frontal circuits in action timing,
the neural basis of "good enough" decision-making (satisficing), and the neural mechanisms
of transcranial magnetic stimulation (TMS).
