Syntalos: a software for precise synchronization of simultaneous multi-modal data acquisition and closed-loop interventions.

Complex experimental protocols often require multi-modal data acquisition with precisely aligned timing, as well as state- and behavior-dependent interventions. Tailored solutions are mostly restricted to individual experimental setups and lack flexibility and interoperability. We present an open-source, Linux-based integrated software solution, called 'Syntalos', for simultaneous acquisition and synchronization of data from an arbitrary number of sources, including multi-channel electrophysiological recordings and different live imaging devices, as well as closed-loop, real-time interventions with different actuators.

Differential suppression of hippocampal network oscillations by neuropeptide Y.

Neuropeptide Y (NPY) is the most abundant neuropeptide in the brain. It exerts anxiolytic and anticonvulsive actions, reduces stress and suppresses fear memory. While its effects at the behavioral and cellular levels have been well studied, much less is known about the modulation of physiological activity patterns at the network level.

A dendrite is a dendrite is a dendrite? Dendritic signal integration beyond the "antenna" model.

Neurons in central nervous systems receive multiple synaptic inputs and transform them into a largely standardized output to their target cells-the action potential. A simplified model posits that synaptic signals are integrated by linear summation and passive propagation towards the axon initial segment, where the threshold for spike generation is either crossed or not. However, multiple lines of research during past decades have shown that signal integration in individual neurons is much more complex, with important functional consequences at the cellular, network, and behavioral-cognitive level.
