interpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولSynaptic enhancement induced through callosal pathways in cat association cortex.
The corpus callosum plays a major role in synchronizing neocortical activities in the two hemispheres. We investigated the changes in callosally elicited excitatory postsynaptic potentials (EPSPs) of neurons from cortical association areas 5 and 7 of cats under barbiturate or ketamine-xylazine anesthesia. Single pulses to callosal pathway evoked control EPSPs; pulse-trains were subsequently app...
متن کاملThe Synaptic Delay of the Motoneurones
It is generally accepted that the response of the motoneurones to excitatory impulses does not appear immediately; a certain time, the synaptic delay, elapses between the arrival of the excitatory impulses at and the firing off of the motoneurone. This assumption is based upon the fact that the reduced latent period of any reflex, i.e., the observed latent period less conduction time in the aff...
متن کاملCandidate interneurones mediating group I disynaptic EPSPs in extensor motoneurones during fictive locomotion in the cat.
In the present study we sought to find interneurones responsible for the group I-evoked disynaptic excitation of hindlimb extensor motoneurones that occurs during fictive locomotion. Locomotion was produced by stimulation of the mesencephalic locomotor region (MLR) in decerebrate paralysed cats in which activation of ankle extensor group I afferents evoked a disynaptic excitation of motoneurone...
متن کاملEffects of Valproic Acid on Axonal Regeneration and Recovery of Motor Function after Peripheral Nerve Injury in the Rat
Background: Valproic acid (VPA) is used to be an effective anti-epileptic drug and mood stabilizer. It has recently been demonstrated that VPA could promote neurite outgrowth, activate the extracellular signal regulated kinase pathway, and increases bcl-2 and growth cone-associated protein 43 levels in spinal cord. In the present research we demonstrate the effect of VPA on peripheral nerve r...
