Synesthesia

synesthesia-6

In synesthesia, information between the senses is blended. Letters might trigger the experience of colors, or sounds the experience of taste, or many other combinations. My laboratory has tested and verified over 20,000 synesthetes, and we are working to understand how it sheds light on consciousness, from the genetics to the neural networks.

Time perception

brainclockgears

To understand the neural mechanisms of time perception, David's lab combines psychophysical, behavioral, and computational approaches to address the relationship between the timing of perception and the underlying neural signals.

Neurolaw

lawbook David is founder and co-director of the Center for Science and Law, which studies how new discoveries in neuroscience can navigate the way we make laws, punish criminals, and develop rehabilitation.

Sensory Substitution

VAC

Can sensory data be fed through unusual sensory channels? And can the brain learn to extract the meaning of such information streams?

Yes and yes. Sensory substitution is a non-invasive technique for circumventing the loss of one sense by feeding its information through another channel.

Other Projects

Other projects in our lab include the use of real-time feedback neuroimaging to break drug addiction, intervention programs in high-violence neighborhoods, word aversion, illusory motion reversal, the flash lag effect, a theory of cerebellar glomeruli, extracellular calcium as a neurotransmitter, and dopamine and human decision-making.

Deep brain recording in humans

DBS

Deep brain stimulation (DBS) targets deep nuclei in the brain to help with Parkinsons Disease or tremor. During surgery, we have a window to measure the responses of single neurons in the human brain. While the recording electrodes are in place, we present sights and sounds to a patient while the responses of the neurons are recorded. Find out more.

From the Blog

David appointed Fellow with Institute for Ethics and Emerging Technologies

Posthumanism asks what happens when our technologies allow humans to enhance intellectual, physical, and psychological capacities beyond what biology can give us. Think bionics on crack.
BrainCheck

How can you collect data reflecting the changes in cognitive function that appear when someone has a concussion? BrainCheck combines neuroscience with a mobile platform to gauge changes from baseline.
Can we produce our brains on other media?

Can we reproduce our brains on other media (say, on computers, or out of beer cans and tennis balls)?
Time perception on the Discovery Channel

Watch an experiment in which we studied time perception by dropping volunteer subjects from a 150 foot high tower. Free fall.

How the Internet will save civilization

David's iPad app "Why the Net Matters, or Six Ways to Avert the Collapse of Civilization" was recently called a "superbook" by the New York Times Magazine. For a taste of the argument, read David's article in WIRED or watch a video of his talk at the Long Now Foundation. Don't have an iPad? The manuscript is now available as an eBook.

Antiphospholipid Syndrome

Far to the left-field of my normal research, I'm pursuing a new hypothesis: whether there is a connection between people who get envenomated by the asp caterpillar, and the acquisition of antiphospholipid syndrome (APS)
