The cellular mechanisms of spike-frequency adaptation during prolonged discharges and of the slow afterhyperpolarization (AHP) that follows, as occur in vivo with contrast adaptation, were investigated with intracellular recordings of cortical neurons in slices of ferret primary visual cortex. Intracellular injection of 2 Hz sinusoidal or constant currents for 20 sec resulted in a slow (tau = 1...

BACKGROUND We studied the anomalous head postures (AHPs) of five monocular viewing patients and investigated the possible causes and the appropriate surgical strategies to correct each condition. METHODS Five patients with acquired visual loss in one eye and associated head tilt and/or turn were examined and treated for correcting the head posture according to the etiology of their respective...

Background: Choosing the most suitable candidate for the position of salesperson is indeed a complex task for managers because several criteria important for the position should be taken into consideration. Such a choice should be considered as a multiple-criteria problem, which can be solved by using the AHP method. Objectives: The main goal is to investigate which criteria are the most import...

Memory acquisition and synaptic plasticity are accompanied by changes in the intrinsic excitability of CA1 pyramidal neurons. These activity-dependent changes in excitability are mediated by modulation of intrinsic currents which alters the responsiveness of the cell to synaptic inputs. The afterhyperpolarization (AHP), a major contributor to the regulation of neuronal excitability, is reduced ...

BACKGROUND Regulatory decision-making involves assessment of risks and benefits of medications at the time of approval or when relevant safety concerns arise with a medication. The Analytic Hierarchy Process (AHP) facilitates decision-making in complex situations involving tradeoffs by considering risks and benefits of alternatives. The AHP allows a more structured method of synthesizing and un...

Memory consolidation, the process of transformation of short-term to long-term memory, has been shown to be protein synthesis dependent in a variety of different learning paradigms, brain structures, and species. At the cellular level, protein synthesis was shown to be crucial for induction of long-term synaptic plasticity; application of protein synthesis inhibitors prevents the transformation...

Supplier selection is a multiattribute decision making (MADM) problem which contains both qualitative and quantitative factors. Supplier selection has vital importance for most companies. The aim of this paper is to provide an AHP based analytical tool for decision support enabling an effective multicriteria supplier selection process in an air conditioner seller firm under fuzziness. In this a...

OBJECTIVE The standard obstetric ultrasound examination includes documentation of arms and legs. The purpose of this study is to review the efficacy of ultrasound for the detection of limb anomalies, the type and incidence of associated malformations and pregnancy outcomes. METHOD All cases of polydactyly (POD), abnormal hand position (AHP), limb reduction defects (LRD) and arthrogryposis (AR...

The selection of appropriate requirements for product releases can make a big difference in a product success. The selection of requirements is done by different requirements prioritization techniques. These techniques are based on pre-defined and systematic steps to calculate the requirements relative weight. Prioritization is complicated by new development settings, shifting from traditional ...

CA1 pyramidal cells receive two major excitatory inputs: the perforant path (PP) terminates in the most distal dendrites, whereas the Schaffer collaterals (SC) terminate more proximally. We have examined the mechanism of the afterhyperpolarization (AHP) that follows single subthreshold excitatory postsynaptic potentials (EPSPs) in these inputs. The AHPs were not reduced by a GABAA antagonist or...
