Chronic neural probe for simultaneous recording of single-unit, multi-unit, and local field potential activity from multiple brain sites

2017

Drug resistant focal epilepsy can be treated by resecting the epileptic focus requiring a precise focus localisation using stereoelectroencephalography (SEEG) probes. As commercial SEEG probes offer only a limited spatial resolution, probes of higher channel count and design freedom enabling the incorporation of macro and microelectrodes would help increasing spatial resolution and thus open new perspectives for investigating mechanisms underlying focal epilepsy and its treatment. This work describes a new fabrication process for SEEG probes with materials and dimensions similar to clinical probes enabling recording single neuron activity at high spatial resolution.Polyimide is used as a bi…

Single- and Partial Multiple-Unit Provisional Restorations in the Esthetic Area

2019

The immediate implant-supported provisional restoration in the partially or totally edentulous patients is a predictable and well-accepted procedure in dentistry. The Glossary of Prosthodontic Terms defines a provisional prosthesis as a prosthesis designed to improve or evaluate esthetics, speech, and occlusal function in a period of time between implant placement and final restoration with a definitive prosthesis. Planning and design should always take place during the pre-surgical phase of treatment and constitute a tool for communication among the members of the team, which in most cases is of a multidisciplinary nature (prosthodontist, surgeon, dental technician, and patient).

Multiple-unit responses to pitch changes in rabbits

1996

Multiple-unit activity (MUA) was recorded from the hippocampus (Hc), the visual cortex (VCx) and the cerebellar cortex (CerCx) in rabbits when pitch deviant tones were presented in a series of standard tones (oddball situation) and when standard tones were absent (deviant-alone situation). Significant MMN-like responses (deviant responses minus standard responses in the oddball situation) occurred in Hc, reflecting a MUA increase to the standards and its decrease to the deviants. In accordance with parallel ERPs reported earlier, the MMN-like responses reflected responses only to different presentation frequencies of stimuli. Non-selectivity in the pitch of such responses in VCx and a lack …
