Internally organized mechanisms of the head direction sense

A Peyrache, MM Lacroix, PC Petersen… - Nature neuroscience, 2015 - nature.com
The head-direction (HD) system functions as a compass, with member neurons robustly
increasing their firing rates when the animal's head points in a specific direction. HD neurons …

Movement is governed by rotational neural dynamics in spinal motor networks

H Lindén, PC Petersen, M Vestergaard, RW Berg - Nature, 2022 - nature.com
Although the generation of movements is a fundamental function of the nervous system, the
underlying neural principles remain unclear. As flexor and extensor muscle activities …

Brain temperature affects quantitative features of hippocampal sharp wave ripples

PC Petersen, M Vöröslakos… - Journal of …, 2022 - journals.physiology.org
Biochemical mechanisms are temperature dependent. Brain temperature shows wide
variations across brain states, and such changes may explain quantitative changes in network …

[PDF][PDF] CellExplorer: A framework for visualizing and characterizing single neurons

PC Petersen, JH Siegle, NA Steinmetz, S Mahallati… - Neuron, 2021 - cell.com
The large diversity of neuron types provides the means by which cortical circuits perform
complex operations. Neuron can be described by biophysical and molecular characteristics, …

Early feeding after necrotizing enterocolitis in preterm infants

…, S Müller, M Dördelmann, CS Peter, C Petersen… - The Journal of …, 2003 - Elsevier
OBJECTIVE: To report our experience with an early initiation of enteral feedings after necrotizing
enterocolitis (NEC). STUDY DESIGN: Over a 4-year period, all inborn infants with NEC …

Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

PC Petersen, RW Berg - elife, 2016 - elifesciences.org
10.7554/eLife.18805.001 When spinal circuits generate rhythmic movements it is important
that the neuronal activity remains within stable bounds to avoid saturation and to preserve …

Metal microdrive and head cap system for silicon probe recovery in freely moving rodent

M Vöröslakos, PC Petersen, B Vöröslakos, G Buzsáki - Elife, 2021 - elifesciences.org
High-yield electrophysiological extracellular recording in freely moving rodents provides a
unique window into the temporal dynamics of neural circuits. Recording from unrestrained …

Premotor spinal network with balanced excitation and inhibition during motor patterns has high resilience to structural division

PC Petersen, M Vestergaard, KHR Jensen… - Journal of …, 2014 - Soc Neuroscience
Direct measurements of synaptic inhibition (I) and excitation (E) to spinal motoneurons can
provide an important insight into the organization of premotor networks. Such measurements …

3D-printed recoverable microdrive and base plate system for rodent electrophysiology

…, H Miyawaki, S Royer, K Diba, E Yoon, PC Petersen… - Bio …, 2021 - bio-protocol.org
Extracellular recordings in freely moving animals allow the monitoring of brain activity from
populations of neurons at single-spike temporal resolution. While state-of-the-art …

[HTML][HTML] Decoupling of timescales reveals sparse convergent CPG network in the adult spinal cord

M Radosevic, A Willumsen, PC Petersen… - Nature …, 2019 - nature.com
During the generation of rhythmic movements, most spinal neurons receive an oscillatory
synaptic drive. The neuronal architecture underlying this drive is unknown, and the …
