The Integrative Neurophysiology (INF) division at the Center for Neurogenomics and Cognitive Research (CNCR) at VU offers a 3-year postdoctoral research project. The focus of the project is on elucidating molecular mechanisms of fast neuronal signaling. A critical requirement of fast neuronal computation and cognitive function is the ability of neurons to generate and maintain fast and stable output - action potentials. Because of difficult access to living human neurons, their function in supporting cognition remains largely unexplored. Our lab has extensive experience in studying the function of human neurons from neurosurgery patients. We recently showed that fast electrical signaling in human neurons directly links to cognitive ability in the same individuals (refs 1,2 below). In the current project, we aim to elucidate molecular mechanisms that underlie fast signaling by manipulating expression of specific genes in human neurons, in organotypic slice cultures as well as human iPSC-derived neurons using CRISPRa/CRISPRi (3,4). We will target genes that have been associated with cognitive ability in human subjects (5). Thereby, we aim to reveal what molecular mechanisms enable human neurons to achieve fast cellular computation ultimately supporting human cognition. As a PhD candidate, your research will aim to uncover the cellular and molecular mechanisms underlying fast electrical signaling in human cortical neurons.
The project is funded by an ERC advanced grant awarded to Prof.dr. Huib Mansvelder: https://inf.cncr.nl/research_teams/Your duties
During the research you use the following approach:
you culture human iPSC-derived neurons and organotypic slices of human brain tissue
you use CRISPRa/CRISPRi tools to manipulate target genes in human neurons, both iPSC-derived as well as in organotypic slice cultures of human brain tissue
you study electrophysiological recordings and analysis from human (iPSC-derived) neurons in cultures
you perform biochemical, transcriptomic and immunohistological analyses of expression in human neurons
Our lab is a part of an inspiring academic environment. In addition to your research, you have an opportunity to participate in teaching. You may also be involved in supervising Bachelor and Master students.

Center for Neurogenomics and Cognitive Research (CNCR)
CNCR includes the Department of Neurosciences at the Faculty of Sciences. The CNCR is a vibrant scientific environment that generates integrated research programs from genes to behavior, each combining mouse and human studies (https://cncr.nl/). In our center, 150 people work closely together in defining how in essence simple molecular and cellular processes shape the emergent complexity of the brain.
We have the specific ambition to unravel the mechanisms by which brain cells and circuitry act both in health and disease. We aim to translate mechanistic knowledge into understanding of (dys)function of the human brain. Our neuroscience research area covers analysis over many spatial levels, from genes to the intact organism, and over a large temporal scale, from microsecond molecular events to the years of functioning of the human brain.
