Short-term adaptation was examined in single unit recordings from 113 superior olive neurons of anaesthetized 3- to 6-month-old Long-Evans rats. Responses to an equal intensity BF probe tone presented 1 ms after an 'adapting' BF tone were adapted by 56.3 +/- 2.6% (mean +/- S.E.) compared to responses at a 512 ms delay. The rapid decrease in discharge rate(More)
Neurons in the lateral superior olivary nucleus (LSO) respond to acoustic stimuli with the "chopper response", a regular repetitive firing pattern with a short and precise latency. In the past, this pattern has been attributed to dendritic integration of synaptic inputs. We investigated a possible contribution of intrinsic membrane properties using(More)
Clinicians utilize electronic health record (EHR) systems during time-constrained patient encounters where large amounts of clinical text must be synthesized at the point of care. Qualitative methods may be an effective approach for uncovering cognitive processes associated with the synthesis of clinical documents within EHR systems. We utilized a(More)
Automated approaches to measuring semantic similarity and relatedness can provide necessary semantic context information for information retrieval applications and a number of fundamental natural language processing tasks including word sense disambiguation. Challenges for the development of these approaches include the limited availability of validated(More)
OBJECTIVE We investigated if auditory neurons have an intrinsic ability to radically transform auditory signals. METHOD We surveyed membrane properties that control coding by neurons, identified with intracellular staining or infrared-DIC videomicroscopy, in three stations of the auditory pathway. We used intracellular and patch-clamp techniques in(More)
The purpose of this study was to understand the factors which promoted the demand for iPads by physicians in two Emergency departments (ED) prior to a system wide implementation of an electronic medical record (EMR). A grounded theory design was employed and 14 semi-structured interviews conducted with ED physicians. Analysis of the interview transcripts(More)
The temporal dependence of neuronal responses in the superior olivary complex (SOC) and central nucleus of the inferior colliculus (ICC) were examined using modified forward masking paradigms. Masking and probe tones were at the unit's best frequency and at the same intensity (20-30 dB above threshold). Short-term adaptation was observed in 85 of 113 SOC(More)
In the lateral superior olive (LSO) the firing rate of principal neurons is a linear function of inter-aural sound intensity difference (IID). The linearity and regularity of the "chopper response" of these neurons have been interpreted as a result of an integration of excitatory ipsilateral and inhibitory contralateral inputs by passive soma-dendritic(More)
The concept of the minimum dataset (MDS) is taking on an increasingly important role in healthcare. In the current environment of health information exchange and universal implementation of electronic health records, work related to the development of one specific type of MDS, the minimum clinical dataset (MCDS), is beginning to permeate the literature.(More)
The impact of implementing a Computerized Provider Order Entry System on ordering patterns is unknown. This study evaluated ordering patterns for CBC, ECG, chest x-ray, BMP, and cardiac enzymes in randomly selected chest pain patients in an adult Emergency Department pre- and post-implementation. The average number of orders documented was significantly(More)
