BRAIN Initiative: Marmoset Coordination Center (U24 Clinical Trials Not Allowed)

This Notice of Funding Opportunity (NOFO) solicits applications to create a Marmoset Coordination Center. The awardee will be responsible for two separate but related activities. The first activity will be to become the repository for genomic, pedigree, and event records (date of birth, medical, reproductive history) for captive marmosets.

BRAIN Initiative: Marmoset Colonies for Neuroscience Research (U24 Clinical Trials Not Allowed)

The common marmoset (Callithrix jacchus) has emerged as a promising nonhuman primate model system to understand the primate brain. This has come about both from the realization that the behavior of the common marmoset is similar in some ways to human behavior and from recent demonstration of germline transmission of exogenous genetic information.

Live spike sorting for multichannel and high-channel recordings

The goal of this project is to create two prototypes of a novel live spike sorting system which can be used by investigators to spike sort streams of neural data recorded by multi-channel, high channel and ultra-high channel probes. In most in-vivo extracellular recording conditions, an electrode can pick up neural spikes from several nearby neurons resulting in so-called “multi-unit” activity in the recording trace.

A Dry Electrode for Universal Accessibility to EEG

Electroencephalography (EEG) measures the brain’s local field potential from the surface of the scalp. This method is useful for studying cognitive processes, neurological states, and medical conditions. Its relative low- cost, ease-of use, and non-invasiveness increase its utility in brain monitoring for both research and medical applications. Unfortunately, the process of acquiring EEG is often not inclusive of all research subjects. EEG typically requires scalp abrasion and application of conductive gels to create a low impedance contact between exposed skin and the electrode tips.
