About our research

Computational Neuroscience

We are interested in understanding how dendrites and their integrative properties contribute to learning and memory functions. Towards this goal, we build abstract mathematical as well as detailed biophysical models of neural cells and circuits across multiple brain regions (hippocampus, amygdala, PFC) and abstraction levels (single neurons, microcircuits, neuronal networks). We then use the models to study how the anatomical, biophysical and plasticity properties of dendrites contribute to memory functions.

Experimental Neuroscience

Our lab has recently expanded its research activities to include experiments in mice. Using head-fixed behavioral set-ups, in vivo imaging and electrophysiology, our primary goal is to probe dendritic contributions to neuronal and circuit computations as well as behavior. Current projects focus on the role of dendritic nonlinearities in the prefrontal cortex and the animal's ability to exhibit behavioral flexibility.

Our latest take on neural computations of the brain is out now | Nature Communications

It’s been 16 years since Dr. Poirazi, head of the lab, got to publish her research on the nonlinear functions of pyramidal neurons; a theoretical prediction that, however prominent may be now, was against all odds and dogmas.

Despite its success, the concept has yet to escape the realm of excitatory neurons, leaving their inhibitory counterparts rather neglected ...

IMBB-FORTH and Columbia University researchers pinpoint the neurons that control brain's memory flow

The laboratories of Dr. Losonczy at Columbia University in New York, and ours, Dr. Poirazi at the Institute of Molecular Biology and Biotechnology (IMBB) of FORTH, joined forces in order to explain how neurons flexibly lay down or recall memories. The study, which was recently published in Neuron, is the first to provide visual evidence that a particular ...
