On power values of pyramidal numbers, I
For m ≥ 3, the mth order pyramidal number is defined by x(x + 1)((m−2)x+5−m)/6. These combinatorial numbers play an important role in number theory and discrete mathematics. For m = 3 and 4, all the power values of these polynomials have been already found. In the present paper the authors deal with square values for larger m. All integer solutions of the corresponding elliptic curves are given...
متن کاملPyramidal Neurons
The effect of the fluorescent Ca2+ indicator dye Fura-2 on Ca2+ dynamics was studied in proximal apical dendrites of neocortical layer V and hippocampal CAl pyramidal neurons in rat brain slices using somatic whole-cell recording and a charge-coupled device camera. A single action potential evoked a transient increase of intradendritic calcium concentration ([Ca2+]i) that was reduced in size an...

متن کاملPyramidal weakness.
The signs associated with an upper motor neurone syndrome vary considerably between text books. Often included are loss of dexterous, rapid and fractionated voluntary movements, variation of movement with mode of activation (prime mover, synergist, antagonist), weakness, various postural signs (eg, pronator drift), time-dependent tonal and tendon reflex changes and the extensor plantar response...
