Independent component analysis of natural image sequences yields spatio-temporal filters similar to simple cells in primary visual cortex

Autor: Hateren, J.H. van, Ruderman, D.L.

Publikováno v: Proceedings of the Royal Society of London. Series B, Biological Sciences, 265(1412), 2315-2320. ROYAL SOC

Simple cells in the primary visual cortex process incoming visual information with receptive fields localized in space and time, bandpass in spatial and temporal frequency, tuned in orientation, and commonly selective for the direction of movement. I

Using miniature sensor coils for simultaneous measurement of orientation and position of small, fast-moving animals

Autor: Schilstra, C., Hateren, J.H. van

Publikováno v: Journal of Neuroscience Methods, 83(2), 125-131. ELSEVIER SCIENCE BV

A system is described that measures, with a sampling frequency of 1 kHz, the orientation and position of a blowfly (Calliphora vicina) flying in a volume of 0.4 x 0.4 x 0.4 m(3). Orientation is measured with a typical accuracy of 0.5 degrees, and pos

Temporal properties of natural scenes

Autor: Hateren, J.H. van, Schaaf, A. van der, Rogowitz, BE, Allebach, JP

Publikováno v: HUMAN VISION AND ELECTRONIC IMAGING, 139-143
STARTPAGE=139;ENDPAGE=143;TITLE=HUMAN VISION AND ELECTRONIC IMAGING

A major problem a visual system faces is how to fit the large intensity variation of natural image streams into the limited dynamic range of its neurons. One of the means to accomplish this is through the use of fast light adaptation of the photorece

A THEORY OF MAXIMIZING SENSORY INFORMATION

Autor: Hateren, J.H. van

Publikováno v: Biological Cybernetics, 68(1), 23-29. SPRINGER

A theory is developed on the assumption that early sensory processing aims at maximizing the information rate in the channels connecting the sensory system to more central parts of the brain, where it is assumed that these channels are noisy and have

Theoretical predictions of spatiotemporal receptive fields of fly LMCs, and experimental validation

Autor: Hateren, J.H. van

Publikováno v: Journal of comparative physiology a-Sensory neural and behavioral physiology, 171(2), 157-170. SPRINGER HEIDELBERG

1. A theory is presented that utilizes the structure of natural images, and how they change in time, to produce spatiotemporal filters that maximize information flow through a noisy channel of limited dynamic range. For low signal-to-noise ratios (SN

Fast temporal adaptation of on-off units in the first optic chiasm of the blowfly

Autor: Jansonius, N.M., Hateren, J.H. van

Publikováno v: Journal of comparative physiology a-Sensory neural and behavioral physiology, 168(6), 631-637. SPRINGER HEIDELBERG

1. We recorded from spiking units in the first optic chiasm between lamina and medulla in the brain of the blowfly (Calliphora vicina). Both previously characterized neuron types, on-off units and sustaining units, were encountered. On-off units had

Directional Tuning Curves, Elementary Movement Detectors, and the Estimation of the Direction of Visual Movement

Autor: Hateren, J.H. van

Publikováno v: Vision Research, 30(4), 603-614. PERGAMON-ELSEVIER SCIENCE LTD

Both the insect brain and the vertebrate retina detect visual movement with neurons having broad, cosine-shaped directional tuning curves oriented in either of two perpendicular directions. This article shows that this arrangement can lead to isotrop

Membrane parameters, signal transmission, and the design of a graded potential neuron

Publikováno v: Journal of comparative physiology a-Neuroethology sensory neural and behavioral physiology, 166(4), 437-448. SPRINGER HEIDELBERG

The large monopolar cells (LMCs) of the fly, Calliphora vicina, visual system transmit graded potentials over distances of up to 1.0 mm. An electrical model was constructed to investigate the design principles relating their membrane parameters to si

Pattern recognition in bees: orientation discrimination

Autor: Hateren, J.H. van, Srinivasan, M.V., Wait, P.B.

Publikováno v: Journal of comparative physiology a-Sensory neural and behavioral physiology, 167(5), 649-654. SPRINGER HEIDELBERG

Honey bees (Apis mellifera, worker) were trained to discriminate between two random gratings oriented perpendicularly to each other. This task was quickly learned with vertical, horizontal, and oblique gratings. After being trained on perpendicularly
