The spread of epileptiform activity was monitored in guinea-pig neocortical slices by the use of a voltage-sensitive dye (RH795) and a fast optical recording technique. Epileptiform activity induced by bicuculline methiodide (10-20 microM) and single-pulse stimulation spread from the stimulation site in layer I or in the white matter across most of the slice. Different lesions were made in the ...

Introduction: Imaging with a reduced field of view (rFOV) is a way to reduce distortion in EPI by acquiring fewer phase-encode lines. However in cases in which regions of signal lie outside the phase field of view, aliasing will occur. This problem has been addressed by suppressing the volume outside the reduced field of view [1] and also by 2D selective excitation [2]. The latter is limited by...

Supragranular pyramidal neurons in the adult rat auditory cortex (AC) show marked long-term potentiation (LTP) of population spikes after tetanic white matter stimulation (TS). For determination of whether this marked LTP is specific to AC, LTP in rat AC slices was compared with LTP in slices of the visual cortex (VC). The amplitude of TS-induced LTP in AC was twice that in VC. LTP of EPSPs was...

This paper is concerned with the defuzzification of the discretised generalised type-2 fuzzy set. In 2008 Liu proposed the α-Plane Representation — a decomposition of the generalised type-2 set into horizontal slices termed ‘α-planes’. An α-plane is akin to an interval type-2 fuzzy set. The α-Plane Representation must be used in conjunction with an interval defuzzification method: The three mai...

Let (X,ω) be a polarized simply connected Calabi-Yau manifold. That is, X is a simply connected compact Kähler manifold of dimension n with zero first Chern class and ω is a Kähler form of X such that [ω] ∈ H(X,Z). In this paper, we study the local properties of the moduli space M of the polarized Calabi-Yau manifold (X,ω). By definition M is the parameter space of the complex structures over X...

In this paper, we propose a new method for morphing between two polygonal, possibly non-simply connected, shapes in the plane. The method is based on reconstructing an xy-monotone surface whose extreme cross-sections coincide with the given shapes. The surface generated by our algorithm does not contain any self-intersections, does not change the topologies of the input slices, does not contain...
