Baclofen reduces post-synaptic potentials of rat cortical neurones by an action other than its hyperpolarizing action.
1. Intracellular recordings were obtained from neurones in layers 2 and 3 of the rat frontal neocortex in an in vitro slice preparation. Three distinct types of stimulation-evoked post-synaptic potentials were recorded in these neurones: excitatory post-synaptic potentials (e.p.s.p.s); bicuculline-sensitive, chloride-dependent inhibitory post-synaptic potentials (i.p.s.p.s) with times to peak o...
متن کاملMembrane resting and action potentials of single cardiac muscle fibers.
An initial report is made on the electrocardiogram of a single heart muscle cell in vivo. The potential variations obtained by electrodes placed on opposite si(les of the membrane of a heart muscle fibre are 50 to 100 times as large as those recorded by stan(lar(l limb leads. The observations support the assumption that during activation the cell interior becomes positive with respect to its su...

15 صفحه اولAction of brain-derived neurotrophic factor on function and morphology of visual cortical neurons
Brain-derived neurotrophic factor (BDNF) is known to play a role in experience-dependent plasticity of the developing visual cortex. For example, BDNF acutely enhances long-term potentiation and blocks long-term depression in the visual cortex of young rats. Such acute actions of BDNF suggested to be mediated mainly through presynaptic mechanisms. A chronic application of BDNF to the visual cor...
