Extracellular single-unit recordings were used to characterize responses of thalamic barreloid and cortical barrel neurons to controlled whisker deflections in 2, 3-, and 4-wk-old and adult rats in vivo under fentanyl analgesia. Results indicate that response properties of thalamic and cortical neurons diverge during development. Responses to deflection onsets and offsets among thalamic neurons...

aim and background: the behavioral inhibition system (bis) and the behavioral activation system (bas) are considered as factors to verify the effects of personality significance on cortical activity. the present study explored the effects of the bis and bas on frontal asymmetry in response to affect stimuli. methods and materials: this study included 36 individuals (18 with high bas sensitivity...

Motor responses evoked by transcranial magnetic stimulation OMS) or transcranial electrical stimulation (TCS) can be facilitated by a prior conditioning stimulus to an afferent nerve. Two facilitation periods are described short (SI), when the nerve stimulus is given near 0 to 10 ms after cranial stimulation, and long (LI), when nerve stimulation is given 25-60 ms before the cranial stimula...

BackgroundEpileptic (absence) seizures in the cerebral cortex can be stopped by pharmacological and optogenetic stimulation of cerebellar nuclei (CN) neurons that innervate thalamus. However, it is unclear how such modify underlying thalamo-cortical oscillations.HypothesisHere we tested whether rhythmic synchronized activity during absence desynchronized single-pulse CN to stop seizure activity...

1. The time sequence of glomerular fibrin deposition, renal cortical fibrinolytic response and thrombocytopenia after thromboplastin infusion in rats has been established. 2. Fibrin clearance is rapid and is associated with markedly increased cortical fibrinolytic activity. 3. Plasma fibrinolytic activity was unchanged. 4. Experiments in which the dose-response relationship between thromboplast...
