Project Summary
Intracranial electrical brain stimulation (EBS) remains a central method in the clinic as well as for research in
several animal model systems. However, little is actually known about the ensembles of neurons activated by
typical and clinical intracranial EBS protocols.

Intersectional transgenic targeting of discrete neuronal and glial subtypes
Investigator
Jeffrey Mumm
Institute
johns hopkins university
Fiscal Year
Funding Opportunities Number
Project Number
PROJECT SUMMARY
Tools for exclusively targeting neuronal and glial subtypes are needed to advance our understanding of the brain.
“Intersectional” systems improve targeting by restricting “reporter/effector” transgenes to a subdomain defined
by the expression overlap between two activating factors.

Abstract
Humans have a remarkable ability to flexibly interact with the environment. A compelling demonstration of this
cognitive flexibility is our ability to respond correctly to novel contextual situations on the first attempt, without
prior rehearsal.

Project Number
Project Summary
All animals share motivated behaviors to fulfill their basic needs for survival, including food, water,
sleep, and social interactions, etc. The homeostatic regulatory system energizes behaviors to defend a
target level for these needs (the homeostatic setpoint).
