Circular inhibition: a new concept in long-range interactions in the mammalian visual cortex

E. Niebur, F. Worgotter
1990 1990 IJCNN International Joint Conference on Neural Networks  
This is not the case for circular inhibition, a new connection scheme we propose for long-range interaction.  ...  Horizontal long range interactions are strongly involved in the generation of the receptive fields of visual cortical cells.  ...  In Section 2 we study the tuning of the orientation selective neurons by intracortical long-range interactions] using a detailed computer simulation of the early visual system.  ...

Accounting for uncertainty: inhibition for neural inference in the cerebellum

Ensor Rafael Palacios, Conor Houghton, Paul Chadderton
2021 Proceedings of the Royal Society of London. Biological Sciences  
Here, we discuss the possible contribution of inhibition to the encoding of precision of neural representations in the granular layer of the cerebellar cortex.  ...  In this review, we equate the ensuing excitation-inhibition balance in the granular layer with the outcome of a precision-weighted inferential process, and highlight the physiological characteristics of  ...  We thank Laurence Aitchison for feedback on the manuscript.  ...

Protective effect of synaptic inhibition during cerebral ischemia in rats and rabbits

P D Lyden, B Hedges
1992 Stroke  
Results: Using the bioassay, we found that muscimol exerted a protective effect in rats (p<0.01). There was a dose-response effect seen in muscimol-treated rabbits.  ...  Antagonists of the excitotoxic amino acid glutamate protect neurons in culture and in animal models of stroke but appear to cause unacceptable side effects in humans.  ...  Acknowledgment We are grateful to Freg Gage, PhD, for the use of the water maze.  ...

Center-surround antagonism in spatial vision: Retinal or cortical locus?

Gerald Westheimer
2004 Vision Research  
Not long afterwards psychophysical experiments revealed a center-surround organization closely matching that found in the mammalian retina.  ...  Mach and Hering had early advanced a model of spatial visual processing featuring an antagonistic interaction between adjoining areas in the visual field.  ...  The impetus was the ''channel'' concept in spatial vision according to which at every place in the visual field there are units of a range of receptive field diameters.  ...

Inhibition stabilization is a widespread property of cortical networks

Alessandro Sanzeni, Bradley Akitake, Hannah C Goldbach, Caitlin E Leedy, Nicolas Brunel, Mark H Histed
2020 eLife  
We find clear evidence for ISN operation in mouse visual, somatosensory, and motor cortex. Simple two-population ISN models describe the data well and let us quantify coupling strength.  ...  Taken together, these results show strong coupling and inhibition stabilization are common features of the cortex.  ...  We made 3 to 4 injections spaced 0.5–1.0 mm apart to cover the visual cortex. After the injections a new cranial window was affixed.  ...
