Evoked activity in the mammalian cortex and resulting behavioral responses exhibit a large variability to repeated presentations of same stimulus. This study examined whether can be attributed ongoing activity. Ongoing evoked spatiotemporal patterns cat visual were measured with real-time optical imaging; local field potentials discharges single neurons recorded simultaneously, by electrophysiological techniques. The appeared deterministic, resulted from dynamics activity, presumably...
The BCI Competition IV stands in the tradition of prior Competitions that aim to provide high quality neuroscientific data for open access scientific community. As experienced already competitions not only scientists from narrow field compete, but scholars with a broad variety backgrounds and nationalities. They include specialists as well students. goals all have always been challenge respect novel paradigms complex data. We report on following challenges: (1) asynchronous data, (2)...
Brain activity can be used as a control signal for brain-machine interfaces (BMIs). A powerful and widely acknowledged BMI approach, so far only applied in invasive recording techniques, uses neuronal signals related to limb movements equivalent, multidimensional of an external effector. Here, we investigated whether this approach is also applicable noninvasive techniques. To end, recorded whole-head MEG during center-out with the hand found significant power modulation between rest movement...
The balanced random network model attracts considerable interest because it explains the irregular spiking activity at low rates and large membrane potential fluctuations exhibited by cortical neurons in vivo. In this article, we investigate to what extent is also compatible with experimentally observed phenomenon of spike-timing-dependent plasticity (STDP). Confronted plethora theoretical models for STDP available, reexamine experimental data. On basis, propose a novel update rule,...
Pain associates both sensory and emotional aversive components, often leads to anxiety depression when it becomes chronic. Here, we characterized, in a mouse model, the long-term development of these components as well anxiodepressive-like consequences neuropathic pain determined their electrophysiological impact on anterior cingulate cortex (ACC, cortical areas 24a/24b). We show that symptoms evolve recover different time courses following nerve injury male mice. In vivo recordings evidence...
Recent studies showed that the low-frequency component of local field potentials (LFPs) in monkey motor cortex carries information about parameters voluntary arm movements. Here, we studied how different signal components LFP time and frequency domains are modulated during center-out Analysis LFPs domain amplitude a slow complex waveform beginning shortly before onset movement is with direction movement. Examining domain, found direction-dependent modulations occur three ranges, which...

It has been proposed that cortical neurons organize dynamically into functional groups (cell assemblies) by the temporal structure of their joint spiking activity. Here, we describe a novel method to detect conspicuous patterns coincident spike activity among simultaneously recorded single neurons. The statistical significance these unitary events is evaluated joint-surprise. tested and calibrated on basis simulated, stationary trains independently firing neurons, which were inserted under...
A central theme in neurobiology is the search for mechanisms underlying learning and memory. Since seminal work, first of Cajal later Hebb, synapse thought to be basic "storing unit." Hebb proposed that information stored by correlation: synapses between neurons, which are often coactive, enhanced. Several recent findings suggest such a mechanism indeed operative nervous system. Pairing activity on presynaptic fibers with strong postsynaptic depolarization results synaptic enhancement. While...
