DEVELOPMENTAL NEUROBIOLOGY LAB

 

WHAT WE DO

Our lab studies the molecular mechanisms that underlie the formation of neural circuits, 

specifically studying the role of adhesion proteins in synapse formation and circuit development

in oligodendrocytes and neurons in the forebrain.

We study several developmental processes: 

1. Proliferation, migration, and differentiation of neurons and glia

2. Synapse formation & Function

3. Myelination

RESEARCH PROJECTS

OLIGODENDROCYTE DEVELOPMENT AND MYELINATION

1. Is activity necessary for oligodendrocyte proliferation and differentiation?

2. Is myelination activity-dependent?

3. Is activity in neuronal- glial microcircuits instructive for myelination?

4. What is the role of ion channel function in OPC differentiation and in neuronal-glial microcircuits? 

5. Do mutations in synaptic adhesion proteins cause defects in neuronal-glial synapse formation and myelination?

ABOUT

Laura Cocas is a developmental neurobiologist at Santa Clara University. She completed her PhD at Georgetown University in the Corbin lab studying the genetic regulation of cell fate in the basal forebrain.. She was then awarded a Fulbright Fellowship to research synapse formation using viral circuit tracing at the University of Basel, Switzerland in the Scheiffele Lab.  She continued her research  as a postdoctoral fellow at UCSF in the Pleasure Lab, using viral tools to probe developing cortical circuits and neural glial connections.


At Santa Clara University, she is a Principal Investigator examining neural circuit formation and myelination in the developing forebrain.

TOOLS AND TECHNIQUES

How we find answers.

We use genetic tools to alter gene expression in the neurons and glia of the embryonic cerebral cortex in vivo and in vitro, using electroporation, transgenic mice, and primary neuronal cultures.

We use viral tools to label and map circuits in the developing cerebral cortex in vivo.

We manipulate activity in neurons using electroporation of channel proteins as well as DREADDs and optogenetics.
