Cross-Correlation in the Auditory Coincidence Detectors of Owls [PDF]
, 2008 Interaural time difference (ITD) plays a central role in many auditory functions, most importantly in sound localization. The classic model for how ITD is computed was put forth by Jeffress (1948). One of the predictions of the Jeffress model is that the

Microcircuitry and function of the inferior olive
Trends in Neurosciences, 1998 The inferior olive, which provides the climbing fibers to Purkinje cells in the cerebellar cortex, has been implicated in various functions, such as learning and timing of movements, and comparing intended with achieved movements. For example, climbing-fiber activity could transmit error signals during eye-blink conditioning or adaptation of the ...

Noise reduction of coincidence detector output by the inferior colliculus of the barn owl [PDF]
, 2006 A recurring theme in theoretical work is that integration over populations of similarly tuned neurons can reduce neural noise. However, there are relatively few demonstrations of an explicit noise reduction mechanism in a neural network.

PLoS Comput. Biol., 2012 It is commonly accepted that the Inferior Olive (IO) provides a timing signal to the cerebellum. Stable subthreshold oscillations in the IO can facilitate accurate timing by phase-locking spikes to the peaks of the oscillation. Several theoretical models

Modulation of Purkinje cell complex spike waveform by synchrony levels in the olivocerebellar system
Frontiers in Systems Neuroscience, 2014 Purkinje cells (PCs) generate complex spikes (CSs) when activated by the olivocerebellar system. Unlike most spikes, the CS waveform is highly variable, with the number, amplitude, and timing of the spikelets that comprise it varying with each ...

Pattern of degeneration of the rat inferior olivary complex after the early postnatal axotomy of the olivocerebellar projection [PDF]
, 1996 Neuronal death of inferior olivary neurons after early axotomy of the olivocerebellar tract was studied in newborn (Pl) hemicerebellectomized rats during the first six days after lesion. The degeneration of the inferior olive showed a topographic pattem

The functional role of GABA and glycine in monaural and binaural processing in the inferior colliculus of horseshoe bats [PDF]
, 1992 The functional role of GABA and glycine in monaural and binaural signal analysis was studied in single unit recordings from the central nucleus of the inferior colliculus (IC) of horseshoe bats (Rhinolophus rouxi) employing microiontophoresis of the ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
Advanced Materials, EarlyView.A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Corollary discharge in precerebellar nuclei of sleeping infant rats
eLife, 2018 In week-old rats, somatosensory input arises predominantly from external stimuli or from sensory feedback (reafference) associated with myoclonic twitches during active sleep.
