The behavior of immature cortical networks in vivo remains largely unknown. Using multisite extracellular and patch-clamp recordings, we observed recurrent bursts of synchronized neuronal activity lasting 0.5 to 3 seconds that occurred spontaneously in the hippocampus of freely moving and anesthetized rat pups. The influence of slow rhythms (0.33 and 0.1(More)
1. Cells derived from a rat pituitary tumour (GC cell line) that continuously release growth hormone behave as endogenous pacemakers. In simultaneous patch clamp recordings and cytosolic Ca2+ concentration ([Ca2+]i) imaging, they displayed rhythmic action potentials (44.7 +/- 2.7 mV, 178 +/- 40 ms, 0.30 +/- 0.04 Hz) and concomitant [Ca2+]i transients (374(More)
Introduction Nodding Syndrome (NS) is a neurological disorder of unknown etiology and pathogenesis, reported to occur mainly in the Western Equatoria State in South Sudan, in several districts in northern Uganda, and in Mahenge district in Tanzania [1]. The characteristic clinical feature of NS is a paroxysmal spell where the head nods forward repeatedly,(More)
A working group, representing ACM, DPMA, and IEEE-CS, was formed to draft a set of guidelines, including criteria, for the accreditation of computer information systems' undergraduate programs. The guidelines and criteria are summarized below. Faculty: Typically a minimum of 4 faculty, with 3 full time, are needed. Normally, 25% of a faculty member's time(More)
