501 It has been widely accepted that spiking neurons code information in their firing rates1. A related assumption is that each neuron serves as an independent channel transmitting information from one stage to another. In principle, however, much more information can be coded in the activity of a neuronal ensemble if temporal correlations between neurons are also used to code additional inform...

The neostriatum is critically involved in the control of movement. The activity of neostriatal neurons is regulated by two major inputs: a glutamatergic input from the cortex and a dopaminergic input from the substantia nigra. Ionotropic glutamate receptors mediate synaptic transmission and plasticity in the neostriatum through intrinsic ligand-gated ion channels. In contrast, dopamine receptor...

563 A ‘motor plan’ may be defined as a set of muscle commands determined before initiation of movement1. This concept has provided theoretical underpinnings for many studies on the generation of visually directed pointing movements2,3. Thus, most authors subordinate the importance of feedback loops, which allow updating of the trajectory throughout its execution. Here we demonstrate the existen...

Cortical neurons in the waking brain fire highly irregular spike trains that have more in common with the ticking of a Geiger counter than of a clock. What is the source of this irregular firing? Softky and Koch1 noted a theoretical conundrum posed by the irregularity of cortical neurons firing at a constant average rate in vivo. If each cortical neuron were providing independent input to the o...
متن کاملI-18: Evaluating Pregnancy and Long-Term Outcomes of ART
When treating infertile couples by assisted reproductive technologies (ART), all aspects of their care in individual clinics should be evaluated frequently. Results should then be compared with other clinics offering similar treatment. Evaluation of possible adverse longterm outcomes can be achieved by pooling results from individual clinics in national, regional and international registers and...
