Distinct developmental trajectories of externally- and internally-generated hippocampal sequences and assemblies Open
The hippocampus generates cognitive maps through two distinct mechanisms: external representations anchored to environmental landmarks and internal sequences integrating self-referenced information. In adult CA1, these functions segregate …

GABAergic neurons are major contributors of network inhibition in the neonatal hippocampus in-vivo Open
During development, neural network maturation is activity dependent. During the neonatal period, activity is provided by intermittent, spontaneous network activity patterns (SNAP) that occur independently of environment stimuli. Among the …

A two-photon lensless endoscope with a double-clad tapered multi-core fiber Open
We present a novel, to the best of our knowledge, multi-core fiber-based lensless micro-endoscope incorporating several key innovations: a Fermat’s golden spiral core layout, a low-index polymer cladding, and a longitudinally varying fiber…

Functional networks of inhibitory neurons orchestrate synchrony in the hippocampus Open
Inhibitory interneurons are pivotal components of cortical circuits. Beyond providing inhibition, they have been proposed to coordinate the firing of excitatory neurons within cell assemblies. While the roles of specific interneuron subtyp…

The rapid developmental rise of somatic inhibition disengages hippocampal dynamics from self-motion Open
Early electrophysiological brain oscillations recorded in preterm babies and newborn rodents are initially mostly driven by bottom-up sensorimotor activity and only later can detach from external inputs. This is a hallmark of most developi…
