A biologically inspired spiking model of visual processing for image feature detection [PDF]
To enable fast reliable feature matching or tracking in scenes, features need to be discrete and meaningful, and hence edge or corner features, commonly called interest points are often used for this purpose.

Sleep neuroimaging: Review and future directions
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

A rare case of facial nerve schwannoma masked by a concomitant temporomandibular disorder pain
Facial nerve schwannoma (FNS) is an uncommon benign tumor that arises from the Schwann cells of the facial nerve (FN). Although rare, this is the most frequent type of FN tumor, potentially affecting any segment of the nerve.

The power ratio and the interval map: spiking models and extracellular data [PDF]
We describe a new, computationally simple method for analyzing the dynamics of neuronal spike trains driven by external stimuli. The goal of our method is to test the predictions of simple spike-generating models against extracellularly recorded neuronal responses. Through a new statistic called the power ratio, we distinguish between two broad classes

A Neural Model of Surface Perception: Lightness, Anchoring, and Filling-in [PDF]
This article develops a neural model of how the visual system processes natural images under variable illumination conditions to generate surface lightness percepts. Previous models have clarified how the brain can compute the relative contrast of images

Nerve growth factor, brain-derived neurotrophic factor, and the chronobiology of mood: a new insight into the "neurotrophic hypothesis" [PDF]
The light information pathways and their relationship with the body rhythms have generated a new insight into the neurobiology and the neurobehavioral sciences, as well as into the clinical approaches to human diseases associated with disruption of ...

A Newly Defined, Common Ophthalmologic Condition Requires Special Neurological Attention
A host of acquired abnormalities in visual function are known to occur in persons who suffer stroke, traumatic brain injury, and neurodegenerative disorders. Cerebral visual impairment occurs in children with early neurological injury or disorders, especially neonatal hypoxic‐ischemic injury.

Spontaneous activity patterns propagate through many parts of the developing nervous system and shape the wiring of emerging circuits. Prior to vision, waves of activity originating in the retina propagate through the lateral geniculate nucleus (LGN) of ...

Robust Estimation of Self-Exciting Generalized Linear Models with Application to Neuronal Modeling [PDF]
We consider the problem of estimating self-exciting generalized linear models from limited binary observations, where the history of the process serves as the covariate. We analyze the performance of two classes of estimators, namely the $\ell_1$-regularized maximum likelihood and greedy estimators, for a canonical self-exciting process and ...

Transformation of stimulus correlations by the retina [PDF]
Redundancies and correlations in the responses of sensory neurons seem to waste neural resources but can carry cues about structured stimuli and may help the brain to correct for response errors. To assess how the retina negotiates this tradeoff, we measured simultaneous responses from populations of ganglion cells presented with natural and artificial
