Response properties of neighboring neurons in the auditory midbrain
… this organization, we characterized the response properties of neighboring neurons in the ICC. To record reliably from neighboring neurons, we adopted a relatively new electrophysiological technique, tetrode recordings. Tetrodes have four closely spaced recording sites (<20[mu]m) which …

Local Correlation: Implementation and Application to Molecular Response Properties
… dissociation of singlet ketene and propadienone. Properties such as polarizabilities and optical rotation are realized through linear response theory, where the Hamiltonian is subject to an external perturbation and the wave function is allowed to respond to the applied perturbation. Within the …

Towards a Reduced-Scaling Method for Calculating Coupled Cluster Response Properties
… coupled cluster theory to calculate ground-state properties of molecular systems with hundreds of heavy atoms in reasonable computational time. However, efforts towards extension of these methods for describing response properties like polarizabilities, optical rotations, etc., which are related …

Development and Assessment of Pair Natural Orbitals Coupled Cluster Quadratic Response Properties
… less progress has been achieved for molecular properties associated with a system's interaction with electromagnetic fields. Advancing this area would enable accurate simulations of light–matter phenomena, such as nonlinear optical (NLO) processes, which are central to the development of …

Towards an Improved Method for the Prediction of Linear Response Properties of Small Organic Molecules
… methods to predict experimental chiroptical properties by solving the time-dependent Schrödinger equation are useful in the assignment of absolute configurations. Chiroptical properties, being very sensitive to the electronic structure of the system, require highly-accurate methods on the one …

The role of serotonergic afferents in receptive field organization and response properties of cells in rat trigeminal subnucleus interpolaris
… as well as changes in receptive field properties throughout the somatosensory neuraxis following damage to peripheral nerves. Chronic changes in receptive fields and response properties have also been reported in the trigeminal brainstem nuclear complex (TBNC) following trigeminal nerve …

Unique Response Properties and GABA<sub>A</sub> Receptor Function in Medial Geniculate Body Neurons of Young and Aged Fischer Brown Norway Rats
… on GABAergic inhibition. To characterize these properties, the inhibitory neurotransmitters involved and how they may be altered in the aged MGB, specific aims sought to: 1) determine the presence of functional high affinity GABA<sub>A</sub> receptors (GABA<sub>A</sub>Rs) in the MGB, 2) …

Cat and monkey V1 neurons : comparison of the responses to sustained and transiently presented stimuli
… presentation methods for the examination of the response properties of neurons in the primary visual cortices (V1) of cats and monkeys have employed extended presentations of luminance modulated sinusoidal grating patterns or spatiotemporal noise (lasting on the order of several seconds) that are …

Precision and reliability of cochlear nerve response in mice lacking functional synaptic ribbons
… molecular machinery, we characterized the response properties of single auditory nerve (AN) fibers in a mouse with targeted deletion of a presynaptic scaffolding gene, bassoon, in which ribbons are no longer anchored to the active zone. Since each mammalian AN fiber usually receives input …

The Effect of Noise Bandwidth and Modulation on Signal Detection for Single Neurons in the Frog Auditory Midbrain
… the detection threshold for single neurons in response to a synthetic advertisement call. Additionally, seasonal effects on the response properties of neurons were also studied. Extracellular recordings were made from single neurons in the auditory midbrain (torus semicircularis) of the frog …

Distinct roles for inhibitory neuron subtypes in cortical circuits : an examination of their structure, function, and connectivity
… 2) How do inhibitory neurons obtain their response selectivity? 3) How do PV+ and SOM+ neurons affect the responses of their targets? and 4) What are the targets of PV+ and SOM+ neurons? We used Cre-lox recombination to introduce either fluorescent protein or channelrhodopsin to PV+ or SOM+ …

Contrast enhancement of ultrasound images using shunting inhibitory cellular neural networks
… and recurrent SICNN systems. Here, the essential response properties of both SICNN Systems are investigated in depth. The enhancing properties of the recurrent SICNN and its advantages compared to more traditional techniques are also studied. After a thorough investigation into the SICNN response …

Conditioned acquisition and augmenting effects in causal attributions for employee performance
… human causal judgments would reflect acquired response properties that can be either increased (augmented) or decreased (discounted). The learning experiment was masked by describing it as a study testing a computerized employee evaluation system.

Deficient experience-dependent plasticity in the visual cortex of Arc null mice
… of Arc influences plasticity, and how visual response properties differ between cells types containing, and not containing Arc. To elucidate a role for Arc in visual cortical plasticity we took advantage of knockin mice expressing GFP in place of Arc protein (referred to as KO mice for …

Accurate Prediction of Chiroptical Properties
… in an effort to extend the calculation of response properties from the gas phase to the condensed phase. This N-body approach performs admirably for interaction energies and even dipole moments but breaks down for optical rotation, exhibiting large basis set superposition errors and …

Likelihood and Bayesian signal processing methods for the analysis of auditory neural and behavioral data
… consensus on how to model neural and behavioral responses and to quantify important response properties is a challenging signal processing problem because models do not always adequately capture the data and different methods often yield different estimates of the same response property. The …
