Connexin 43 Hemichannels Are Permeable to ATP
Astrocytes are electrically nonexcitable cells that communicate by means of Ca2+ signaling. Long-distance intercellular Ca2+ waves are initiated by release of ATP and activation of purinergicExpand

Activity-Dependent Long-Term Potentiation of Intrinsic Excitability in Hippocampal CA1 Pyramidal Neurons
The efficiency of neural circuits is enhanced not only by increasing synaptic strength but also by increasing intrinsic excitability. In contrast to the detailed analysis of long-term potentiationExpand

Astrocytic glutamate release-induced transient depolarization and epileptiform discharges in hippocampal CA1 pyramidal neurons.
A paroxysmal depolarization shift (PDS) has been suggested to be a hallmark for epileptic activity in partial-onset seizures. By monitoring membrane potentials and currents in pairs of pyramidalExpand

A Central Role of Connexin 43 in Hypoxic Preconditioning
Preconditioning is an endogenous mechanism in which a nonlethal exposure increases cellular resistance to subsequent additional severe injury. Here we show that connexin 43 (Cx43) plays a key role inExpand

Changes in the composition of brain interstitial ions control the sleep-wake cycle
Sleep induction through ion changes How do we switch from sleep to arousal and back? Ding et al. found that a combination of modulatory neurotransmitters influenced the levels of extracellular ionsExpand

Learning multi-finger synergies: an uncontrolled manifold analysis
We used the uncontrolled manifold (UCM) approach to study the synergy formation during learning an unusual multi-finger task. The subjects produced accurate force ramps with challenging sets of fourExpand

Isolation and Identification of Urinary Metabolites of Berberine in Rats and Humans
The urinary metabolites of berberine, an isoquinoline alkaloid isolated from several Chinese herbal medicines, were investigated in rats and humans. Using macroporous adsorption resin chromatography,Expand

Effects of age and gender on finger coordination in MVC and submaximal force-matching tasks.
The objective of the study is to examine the effects of age and gender on finger coordination. Twelve young (24 +/- 8 yr; 6 men and 6 women) and 12 elderly (75 +/- 5 yr; 6 men and 6 women) subjectsExpand

Finger coordination in persons with Down syndrome: atypical patterns of coordination and the effects of practice
The study addresses an issue of possible relations between the apparent “clumsiness” of persons with Down syndrome (DS) and changes in indices of finger coordination. We hypothesized that personsExpand
